That thick, viscous liquid you've been pouring down the drain when opening a can of chickpeas? It's actually culinary gold. Known as aquafaba, this unlikely egg replacement has revolutionized plant-based cooking, making previously impossible recipes accessible to those avoiding animal products. Whether you're looking to replace eggs for ethical reasons, environmental concerns, or allergies, aquafaba offers a versatile solution that actually works.
Plant-based cooking enthusiasts have embraced aquafaba as a game-changing ingredient that performs remarkably like eggs in recipes ranging from delicate meringues to rich mayonnaise. This miracle liquid, discovered by resourceful vegan bakers, has been championed by innovative plant-based cooking experts who continue to discover new applications for this sustainable ingredient. The best part? It's essentially free if you're already using chickpeas in your cooking.
What Is Aquafaba? The Magic Bean Water Revolutionizing Plant-Based Cooking
Aquafaba (Latin for "bean water") is the viscous liquid that results from cooking legumes, most commonly chickpeas. The starchy water mimics many of the properties of egg whites and whole eggs in cooking and baking. While chickpea liquid is the most popular source, aquafaba can also be obtained from other beans including white beans, black beans, and even the cooking liquid from other legumes.
The discovery of aquafaba as an egg replacer is relatively recent. In 2014, French chef Joël Roessel found that the liquid from canned beans could be whipped into foam. Shortly after, American software engineer Goose Wohlt discovered that this liquid could create stable meringues, and the plant-based community quickly embraced this groundbreaking ingredient. By 2015, the term "aquafaba" was coined, and an entirely new approach to egg-free cooking was born.
What makes aquafaba truly remarkable is its ability to trap air when whipped, emulsify oils when blended, and provide structure when baked – all properties traditionally associated with eggs. This transformative ingredient contains a unique combination of starches, proteins, and other soluble plant solids that create a functional substitute in recipes where eggs provide crucial structural elements.
Aquafaba at a Glance:• Origin: Cooking liquid from legumes (primarily chickpeas)• Appearance: Pale yellow, slightly viscous liquid• Egg Replacement Ratio: 3 Tbsp = 1 whole egg; 2 Tbsp = 1 egg white• Primary Uses: Meringues, mayonnaise, mousses, baked goods• Storage: 1 week refrigerated, 3+ months frozen
Why Aquafaba Works As An Egg Replacement
The magic of aquafaba lies in its unique molecular composition. When chickpeas or other legumes cook, they release a combination of proteins, starches, and soluble plant solids into the cooking water. This combination creates a solution that behaves remarkably like egg whites and whole eggs in various culinary applications. The proteins provide structure, while the starches add binding power and stability.
Unlike many commercial egg replacers that work in limited applications, aquafaba can perform nearly all the functions of eggs in recipes. It can bind ingredients together in cookies and cakes, leaven baked goods, emulsify dressings and sauces, and even whip into stiff peaks for meringues – a feat that was considered impossible without eggs before aquafaba's discovery.
Perhaps most importantly for plant-based cooking enthusiasts, aquafaba works without adding any additional flavors to your recipes. Once cooked or baked, there's no discernible bean taste, making it a truly neutral egg replacement that doesn't compromise the flavor profile of your culinary creations.
The Science Behind Its Whipping Power
Aquafaba's most impressive characteristic is its ability to whip into stiff peaks, just like egg whites. This property comes from its unique protein structure, which forms stable air bubbles when agitated. The proteins in aquafaba unfold and reorganize around air pockets, creating a foam that can maintain its structure even when baked. While egg whites whip up more quickly, aquafaba produces similarly stable foams with a bit more patience and time. For more information on aquafaba's uses, check out this guide to aquafaba as a vegan egg replacer.
Nutritional Profile Compared to Eggs
While aquafaba excels at mimicking the functional properties of eggs, its nutritional profile differs significantly. Aquafaba contains far fewer calories and proteins than eggs, making it a lighter option for baking. A whole egg contains about 70 calories and 6 grams of protein, while 3 tablespoons of aquafaba (the equivalent replacement) contains only about 3-5 calories and trace amounts of protein. For those concerned about cholesterol, aquafaba contains none, compared to the approximately 186mg found in a standard egg.
Environmental Benefits of Choosing Aquafaba
Choosing aquafaba as an egg replacement significantly reduces your environmental footprint. Conventional egg production creates substantial greenhouse gas emissions, requires large amounts of land and water, and often involves questionable animal welfare practices. By contrast, aquafaba is essentially a byproduct that would otherwise be discarded, making it a zero-waste ingredient that aligns perfectly with sustainable cooking principles.
Legume production also requires far fewer resources than egg production. Chickpeas and other beans fix nitrogen in soil, reducing the need for synthetic fertilizers and improving soil health. This circular approach to cooking—using every part of your ingredients—represents the future of sustainable food systems that environmentally-conscious cooks are increasingly embracing.
How To Make Aquafaba At Home
Lotus Ministry Trust Provides Nutritious Plant-Based Meals to Communities in Need - Your Support Makes a Difference
While canned chickpea liquid is the most convenient source of aquafaba, making it from scratch gives you complete control over the ingredients and consistency. Homemade aquafaba can be tailored to your specific needs and typically produces a cleaner flavor profile than the canned variety, which may contain added salt or preservatives.
The process requires minimal active time and yields both aquafaba and cooked chickpeas for other recipes. Many plant-based cooking enthusiasts find that making a large batch of aquafaba and freezing it in ice cube trays creates a convenient supply for spontaneous baking projects. The frozen cubes can be thawed quickly when needed, making egg-free cooking accessible at a moment's notice.
Using Canned Chickpea Liquid
The simplest method for obtaining aquafaba is draining the liquid from a can of chickpeas into a container. One standard 15-ounce can typically yields about ¾ cup of aquafaba, enough to replace 4 whole eggs. For best results, choose cans with no added salt or preservatives, and look for chickpeas packed in water rather than brine. If your recipe requires a thicker consistency, you can simmer the liquid to reduce it by about one-third, creating a more concentrated product.
Creating Aquafaba From Dried Beans
Making aquafaba from dried chickpeas produces a cleaner flavor and allows complete control over the ingredients. Soak 1 cup of dried chickpeas in water overnight, then drain and rinse thoroughly. Place the soaked chickpeas in a pot with 3 cups of fresh water and simmer for 45-60 minutes until tender. The cooking liquid will transform into aquafaba as the beans release their starches and proteins into the water.
After cooking, strain the liquid and allow it to cool completely before using. This homemade version may require reduction to achieve the optimal consistency. The ideal aquafaba should have a viscosity similar to egg whites—able to coat the back of a spoon but still pour easily.
Reducing Aquafaba For Better Results
If your aquafaba seems too thin or watery, reducing it can significantly improve its performance. Place the liquid in a wide-bottomed pan over medium-low heat and simmer gently until it has reduced by about one-third of its original volume. The resulting concentrated aquafaba will have greater binding power and whip more successfully into stiff peaks. Reduced aquafaba works particularly well in delicate applications like meringues and macarons, where stability is crucial.
Storage Tips For Homemade Aquafaba
Fresh aquafaba keeps well in an airtight container in the refrigerator for up to a week. For longer storage, freezing is remarkably effective and doesn't diminish its functional properties. Pour aquafaba into ice cube trays (each compartment typically holds about 2 tablespoons) and freeze until solid. Transfer the frozen cubes to a freezer bag, where they'll keep for at least 3 months. Thaw at room temperature or in the refrigerator before using, and whip or incorporate as needed.
Perfect Substitution Ratios For Every Recipe
Understanding the correct proportions for replacing eggs with aquafaba is crucial for successful plant-based baking. While these ratios provide a reliable starting point, remember that different recipes may require slight adjustments based on the specific role eggs play in that particular dish. The more you experiment with aquafaba, the more intuitive these substitutions will become.
Generally speaking, aquafaba works best in recipes where eggs provide structure, binding, or leavening. It may be less effective in recipes where eggs are the primary ingredient, such as frittatas or quiches, though innovative plant-based cooks continue to push these boundaries with remarkable success.
Replacing Whole Eggs In Baking
When substituting for whole eggs in baking recipes like cakes, cookies, and quick breads, use 3 tablespoons of aquafaba for each egg called for in the recipe. Unlike some commercial egg replacers that work only in specific applications, aquafaba performs remarkably well across a wide range of baked goods. For more information on aquafaba, you can check out this comprehensive guide. For recipes requiring multiple eggs, simply scale up the amount proportionally—a recipe calling for 3 eggs would use 9 tablespoons (slightly more than ½ cup) of aquafaba.
In recipes where eggs primarily provide moisture and binding, like brownies or muffins, aquafaba can be used straight from the can or container without whipping. Simply measure and add it to your wet ingredients as you would eggs. The starches and proteins in aquafaba will bind your ingredients together and help create the proper texture in your finished baked goods.
Substituting For Egg Whites Only
For recipes that call specifically for egg whites, such as meringues, pavlovas, or angel food cake, use 2 tablespoons of aquafaba for each egg white needed. This application is where aquafaba truly shines, creating stable foams that can be baked into crisp meringues or folded into batters for light, airy cakes. When whipped, aquafaba increases in volume just like egg whites, though it typically requires a longer whipping time to reach stiff peaks—about 8-10 minutes with a stand mixer.
When To Add Stabilizers Like Cream Of Tartar
While aquafaba can whip up on its own, adding a stabilizer dramatically improves its performance and longevity. Just as with traditional egg whites, adding ¼ teaspoon of cream of tartar per cup of aquafaba helps achieve stiffer peaks and prevents deflation. The acid in cream of tartar strengthens the protein bonds in the aquafaba, creating a more stable foam that holds its shape longer.
For recipes requiring extended whipping or that need to hold their shape for long periods, such as macarons or meringue cookies, stabilizers are especially important. If cream of tartar isn't available, a few drops of lemon juice or white vinegar can serve as alternatives, though they may impart a subtle flavor. For sweet applications, a small amount of sugar added gradually during whipping also helps stabilize the foam.

Amazing Things You Can Make With Aquafaba
The versatility of aquafaba extends far beyond basic egg replacement. This remarkable ingredient has opened up a world of possibilities for plant-based cooking, making previously impossible recipes accessible to those avoiding eggs. From delicate pastries to creamy condiments, aquafaba performs admirably across a stunning range of culinary applications.
Meringues and pavlovas - Whipped to stiff peaks with sugar for classic crispy-outside, chewy-inside treats
Mousses and puddings - Creates light, airy textures without heavy cream
Mayonnaise and aioli - Emulsifies oils perfectly for creamy, egg-free condiments
Marshmallows - Combined with sugar syrup for fluffy, gelatin-free treats
Macarons - The holy grail of vegan baking, now possible with aquafaba
Buttercream - Whipped with sugar for fluffy, stable frostings
Cakes and brownies - Creates moisture and structure in baked goods
Ice cream - Adds creaminess without dairy or eggs
Nougat and fudge - Forms the base for egg-free confections
Fluffy Meringues And Pavlovas
Perhaps the most impressive feat of aquafaba is its ability to create perfect meringues and pavlovas. To make basic aquafaba meringues, whip ¾ cup of aquafaba with ¼ teaspoon cream of tartar until foamy, then gradually add 1 cup of superfine sugar while continuing to whip until stiff, glossy peaks form. Pipe or spoon onto baking sheets and bake at a low temperature (200°F/95°C) for about 90 minutes until crisp. The result is indistinguishable from traditional egg white meringues – crisp exteriors with slightly chewy centers.
Light And Airy Mousses
Aquafaba makes creating decadent yet light plant-based mousses remarkably simple. For a basic chocolate mousse, melt 7 ounces of dairy-free dark chocolate, let it cool slightly, then fold it into ½ cup of aquafaba that has been whipped to stiff peaks with 2 tablespoons of sugar. The aquafaba holds air bubbles remarkably well, creating a texture that's virtually identical to traditional egg-based mousses. Chill until set and serve with fresh berries for an impressive dairy-free dessert that will surprise even the most dedicated omnivores.
Vegan Mayonnaise And Aiolis
Homemade mayonnaise becomes surprisingly simple with aquafaba. In a blender or food processor, combine 3 tablespoons of aquafaba with 1 teaspoon of mustard, 1 tablespoon of lemon juice, and a pinch of salt. With the machine running, slowly drizzle in 1 cup of neutral oil until thick and emulsified. The resulting mayonnaise is creamy, rich, and completely plant-based, with none of the additives found in commercial vegan mayonnaise. For variations, add minced garlic for aioli, chipotle peppers for a spicy version, or fresh herbs for a garden-inspired spread.
Beyond Chickpeas: Other Beans That Work As Aquafaba
While chickpea liquid remains the most popular source of aquafaba, other legumes can
produce excellent results with slightly different characteristics. Experimenting with alternative bean varieties allows you to tailor the aquafaba to specific recipes, potentially enhancing both flavor and performance. The liquid from any canned or home-cooked bean contains the necessary proteins and starches that give aquafaba its egg-like properties.
Different beans produce aquafaba with varying colors and subtle flavor differences, which can be strategically matched to your recipes. The cooking method also influences the quality of the resulting aquafaba, with pressure cooking typically yielding a more concentrated liquid than stovetop methods.
White Bean Aquafaba For Neutral Flavor
Cannellini beans, navy beans, and other white beans produce an aquafaba with an exceptionally neutral flavor profile and pale color. This makes white bean aquafaba particularly well-suited for delicate applications where even the subtle taste of chickpea aquafaba might be detectable. White bean aquafaba performs admirably in vanilla cakes, and light-colored frostings where visual appeal is important. The liquid tends to be slightly less viscous than chickpea aquafaba, so it sometimes benefits from a brief reduction to concentrate its proteins and starches.
Black Bean Liquid For Chocolate Recipes
The dark liquid from black beans creates an aquafaba that's perfect for chocolate recipes. The slight color and earthy undertones are completely masked by cocoa, making black bean aquafaba ideal for brownies, chocolate cakes, and chocolate mousse. This strategic pairing allows you to make use of a bean liquid that might otherwise be discarded while creating plant-based chocolate desserts with perfect texture and no discernible bean flavor. When using black bean aquafaba in chocolate recipes, you can often skip the reduction step as the darker color won't affect the final appearance.
Troubleshooting Common Aquafaba Problems

Even experienced plant-based cooks occasionally encounter challenges when working with aquafaba. Understanding the science behind this remarkable ingredient helps troubleshoot common issues and achieve consistent results. Most problems stem from either the quality of the aquafaba itself or the techniques used to prepare it. With a few adjustments, these challenges can be easily overcome, leading to perfect plant-based creations every time.
Why Your Aquafaba Won't Whip
If your aquafaba refuses to form stiff peaks, several factors may be at play. First, ensure your aquafaba is sufficiently concentrated – it should have a consistency similar to egg whites. If it seems watery, reduce it by simmering until it coats the back of a spoon. Also crucial is using impeccably clean equipment, as any trace of oil or fat will prevent proper whipping. The temperature matters too – cold aquafaba whips better than room temperature, so consider chilling it before whipping. Finally, patience is key – aquafaba typically takes 8-10 minutes of continuous whipping to reach stiff peaks, significantly longer than egg whites.
Fixing Flat Meringues
Flat or collapsed meringues usually indicate stability issues with your aquafaba foam. Adding stabilizers like cream of tartar or a small amount of xanthan gum (about ⅛ teaspoon per cup of aquafaba) can dramatically improve stability. Baking temperature is equally important – meringues need a low, slow bake (around 200°F/95°C) to dry out without collapsing.
Humidity can also sabotage meringues, so avoid making them on particularly humid days, and store finished meringues in an airtight container with a desiccant packet to maintain their crisp texture.
Eliminating The Bean Flavor
While aquafaba's bean flavor is typically mild and disappears during cooking, some sensitive palates may detect it in delicate applications. To minimize any bean taste, use white bean aquafaba for the most neutral flavor profile. Alternatively, add complementary flavors that mask any subtle bean notes – vanilla extract works wonders in sweet recipes, while lemon juice helps in savory applications. Another effective strategy is to reduce homemade aquafaba with aromatics like a split vanilla bean or lemon peel, which infuse the liquid while concentrating it, effectively replacing any bean notes with more desirable flavors.
Aquafaba Is Your Secret Weapon In Plant-Based Cooking
Aquafaba represents the innovative spirit of plant-based cooking – turning what was once considered waste into a versatile ingredient that outperforms many commercial egg replacers. As you experiment with this remarkable liquid in your kitchen, you'll discover countless creative applications that make plant-based cooking more accessible and exciting. The best plant-based cooking doesn't try to merely imitate traditional recipes – it reimagines them with ingredients that stand on their own merits, and aquafaba exemplifies this philosophy perfectly.
Frequently Asked Questions
As aquafaba continues to gain popularity, many home cooks have questions about its use, storage, and properties. These frequently asked questions address the most common concerns and help demystify this remarkable egg replacer.
How long does aquafaba last in the refrigerator?
Fresh aquafaba can be stored in an airtight container in the refrigerator for 4-7 days. You'll know it's still good if it maintains its slightly viscous consistency and has no off smell. If you've reduced your aquafaba to concentrate it, the higher concentration of starches and proteins may allow it to last slightly longer, up to a week. For optimal results when whipping refrigerated aquafaba, allow it to come to room temperature first, then re-chill in the mixing bowl before whipping.
Can I freeze aquafaba for later use?
Absolutely! Aquafaba freezes beautifully with no loss of its functional properties. Pour it into ice cube trays for easy portioning – each standard ice cube compartment holds about 2 tablespoons of liquid. Once frozen, transfer the cubes to a freezer bag where they'll keep for at least 3 months.
When you're ready to use frozen aquafaba, simply thaw it in the refrigerator overnight or at room temperature for a few hours. Once thawed, it performs exactly like fresh aquafaba, whipping up to the same volume and providing the same binding properties in recipes.
Does aquafaba contain protein like eggs do?
Aquafaba contains some protein, but significantly less than eggs. While a large egg provides about 6 grams of protein, the equivalent amount of aquafaba (3 tablespoons) contains only about 1 gram of protein. The magic of aquafaba lies not in its protein content but in the unique combination of proteins and starches that mimic the functional properties of eggs.
For recipes where eggs are valued primarily for their protein content, you might want to supplement aquafaba with other protein-rich plant foods. However, for most baking and cooking applications, aquafaba's structural properties matter more than its nutritional profile, making it an excellent functional replacement regardless of protein content.
Will my baked goods taste like beans when using aquafaba?
When properly incorporated into recipes, aquafaba leaves no discernible bean flavor in the finished product. The mild taste of aquafaba dissipates during cooking and baking, and is easily masked by other ingredients. In sweet recipes, even a small amount of vanilla extract or other flavorings completely eliminates any subtle bean notes. For those with particularly sensitive palates, using white bean aquafaba provides an even more neutral starting point than chickpea liquid.
Is aquafaba safe for people with legume allergies?
Individuals with legume allergies should avoid aquafaba, as it contains proteins from the beans it's derived from. While the protein content is lower than in the beans themselves, these proteins can still trigger allergic reactions in sensitive individuals. For those with legume allergies seeking egg alternatives, consider commercial egg replacers based on starches, flaxseed gel, or fruit purees depending on the specific application.
