How to Use Aquafaba. The cooking egg replacer.

Aquafaba is the slightly magical liquid you find inside a can of chickpeas (garbanzo beans).Yes,  the one you used to pour down the drain without thinking, well that is a luscious vegan egg substitute for baking.

That humble chickpea water can be whipped into clouds, folded into batters, baked into cookies, and transformed into glossy vegan meringue with the same structure and lift as egg whites. It sounds fake. It’s not. It’s kitchen science.

So… What Is Not Aquafaba?

Let’s clear up the confusion:

Aquafaba is not:

• The liquid from any random canned bean (not the same substance as chickpeas).
• Just chickpeas blended with water
• The water you soak dry chickpeas in
• A weird processed substitute

It’s specifically the cooking liquid from chickpeas (garbanzo beans), the one that turns slightly thick and golden because it’s full of starches and plant proteins. That’s where the magic lives.

Is Aquafaba Healthy?

You’re not using aquafaba because it’s a protein powerhouse,  you’re using it because it works.

But it still comes with some nutritional value 

• Naturally fat-free
• Very low in calories
• Zero cholesterol
• Helps reduce food waste

It’s also one of the most budget-friendly egg replacements ever, because it starts with an ingredient many of us already have in the pantry.

Why Does It Work Like Eggs?

This is the part that feels like a science experiment (the fun kind). Aquafaba contains dissolved:

• starches
• proteins
• soluble plant solids

When you whip a few tablespoons of aquafaba, those elements trap air and create a foam,  exactly what happens when you whip egg whites.

That foam can:

• expand
• hold structure
• turn glossy
• bake into crispy or fluffy textures

Which means it can act as a binder, a leavening agent, or a base for mousses and frostings. Same function. Different source.
Similar properties, completely plant-based and cruelty free. 

Why Everyone Fell in Love With It

Aquafaba changed plant-based baking because it solved the texture problem.

Not the flavor. Not the ethics. The texture.

It made it possible to create:

• light
• airy
• fluffy
• chewy
• crispy

How to Make Aquafaba at Home (Without Using a Can)

You don’t need a can of chickpeas to get good aquafaba, you can make your own by cooking dry chickpeas and using the reduced cooking liquid. It’s the same chickpea water, just less salty and fully in your control.

NOTE: I prefer using canned aquafaba, is quicker, easier, and more stable (sometimes cooking it at home is a lot of headache and it doesnt turn out as thick as you need it. 

Start by soaking dry chickpeas overnight, then simmering them in fresh water until tender. As they cook, the starches and plant proteins release into the liquid — that’s what gives aquafaba its similar properties to egg whites.

Once the chickpeas are done:

• Strain the cooking liquid
• Return it to the pot
• Let it simmer until slightly thickened

You’re looking for a texture similar to the liquid from a can — viscous, lightly golden, and able to coat a spoon.After cooling, measure it the same way you would from a can: about 3 tablespoons of aquafaba = 1 egg white.

Homemade aquafaba is perfect for both whipped applications like vegan meringue and unwhipped uses in cookies, cakes, and pancakes — and it’s one of the best different ways to reduce waste while keeping your pantry fully plant-based.

What Can You Make With Aquafaba?

Once you start using it, you realize there are so many different ways to work with it.

Some classics:

• Chocolate Mousse: By beating a few tablespoons of aquafaba  into stiff peaks and folding it into melted chocolate, you get a rich dessert that feels decadent but completely egg-free.

• Pancakes: The trapped air in whipped chickpea water creates lift, while its structure holds the batter together, one of the easiest different ways to replace eggs in everyday breakfasts.

• Cookies: In cookies, aquafaba is usually added unwhipped. Just a few tablespoons of aquafaba act like egg whites, helping with moisture, chewiness, and structure. It’s a simple swap that keeps the texture soft in the center and crisp on the edges.

• Lava Cake: Aquafaba gives vegan lava cake its delicate crumb while allowing the center to stay molten. Thanks to its similar properties to eggs, it binds the batter without making the cake dense, creating that classic contrast between fluffy cake and liquid chocolate.

• Pavlova: This is where aquafaba becomes a show-off. When you whip chickpea water with sugar, it transforms into a glossy vegan meringue that can be baked into a pavlova with a crisp shell and marshmallow-soft center, just like traditional versions made with egg whites.

• Vegan Meringue: The most iconic use. Whipped aquafaba turns into a stable foam that behaves almost exactly like egg whites, making it perfect for piping, torching, or baking. It’s the base that proves how powerful this ingredient is and why there are so many different ways to use it.

The Takeaway

Aquafaba is one of those ingredients that makes you feel like you’ve unlocked a secret level in the kitchen. It’s:

• simple
• affordable
• low-waste
• wildly versatile

And it turns a pantry staple into something that can whip, fluff, bind, and bake like a dream. Not bad for bean water.
