The best egg replacements depend on what the egg does in your recipe

An egg in a recipe usually does one of three things: it binds ingredients together, it makes baked goods rise, or it adds moisture. The replacement you choose depends on which job the egg is doing. A flax egg works well for binding in cookies, but it won't help a cake rise the way a real egg does. Applesauce adds moisture to brownies but won't hold a quiche together. Knowing what your recipe needs—not just that it has an egg—is the first step to a successful swap.

Most egg replacements work best in recipes where eggs are not the star ingredient. A custard or soufflé relies entirely on eggs to get its texture, so swapping them out is much harder than replacing an egg in a chocolate cake where three other ingredients are doing most of the work. If your recipe calls for more than two eggs, or if it's a custard, meringue, or angel food cake, you may want to look for a recipe designed for your dietary needs rather than forcing a replacement.

Key Takeaways

  • Flax eggs and chia eggs work best for binding in cookies, brownies, and quick breads where you don't need the recipe to rise much.
  • Applesauce, mashed banana, and yogurt add moisture to cakes and muffins but can make them denser and change the flavor.
  • Aquafaba (the liquid from canned chickpeas) whips into peaks like egg whites and works for meringues and some cakes that need lift.
  • Baking soda or baking powder mixed with an acid like vinegar or lemon juice can replace the rising power of eggs in quick breads and cakes.
  • Cornstarch, arrowroot powder, and commercial egg replacers work as binders in savory dishes like veggie patties and meatballs.

Flax eggs and chia eggs for binding and structure

A flax egg is made by mixing 1 tablespoon of ground flaxseed with 3 tablespoons of water and letting it sit for 5 to 10 minutes until it becomes gel-like. One flax egg replaces one regular egg. Flax eggs work well in recipes where the egg is mainly binding ingredients—cookies, brownies, muffins, and quick breads. They add a subtle nutty flavor and work especially well in chocolate or spiced baked goods where that flavor fits.

Flax eggs do not help recipes rise, so they are not the right choice for angel food cake or any recipe where the egg white is whipped for volume. They also work best in recipes with strong flavors; in a delicate vanilla cake, the flax flavor may stand out. A chia egg works the same way—1 tablespoon of chia seeds mixed with 3 tablespoons of water, left to sit for 15 minutes. Chia eggs are slightly less flavorful than flax eggs and work in a wider range of recipes, though they cost more.

Applesauce, banana, and yogurt for moisture and tenderness

Applesauce, mashed banana, and plain yogurt all add moisture to baked goods. Use 1/4 cup of applesauce or mashed banana to replace one egg, or 1/4 cup of yogurt. These work well in cakes, muffins, brownies, and quick breads. The result will be slightly denser and moister than with eggs, which many people prefer. Applesauce is the most neutral flavor-wise; banana will taste like banana; yogurt adds a slight tang.

The trade-off is that these replacements do not help the recipe rise. If your recipe relies on eggs for lift—a sponge cake, for example—the result will be flatter. Also, applesauce and banana add sugar to the recipe, so you may want to reduce the sugar called for by 2 to 3 tablespoons per egg replaced. Yogurt does not add much sugar, so it needs no adjustment. These replacements work best in recipes that already have fat (butter or oil) and where a denser crumb is acceptable.

Aquafaba for whipping and lift

Aquafaba is the liquid drained from a can of chickpeas (or other beans). Three tablespoons of aquafaba replaces one egg white. When you whip aquafaba with a mixer for 5 to 10 minutes, it forms stiff peaks just like egg whites do. This makes it the only egg replacement that can truly replace the rising power of eggs in recipes like meringues, angel food cake, or chiffon cake.

Aquafaba works best when the recipe calls for egg whites only, not whole eggs. If your recipe calls for whole eggs, you can use aquafaba for the whites and another replacement (like applesauce) for the yolks, but this gets complicated. Aquafaba has a slight bean flavor that is usually hidden in chocolate or spiced cakes but may show up in vanilla or lemon recipes. Start with one cake made with aquafaba before committing to it for a special occasion.

Baking soda and acid for rise in quick breads and cakes

Baking soda mixed with an acid can replace the rising power of eggs in some recipes. For each egg, mix 1 tablespoon of baking soda with 1 tablespoon of lemon juice, vinegar, or yogurt. Let it sit for a few minutes until it foams, then add it to your batter. This works well in quick breads, pancakes, waffles, and some cakes where the recipe already has other wet ingredients.

This method works because the acid reacts with the baking soda to create carbon dioxide bubbles, which help the recipe rise. It does not work as well as eggs do, and the result will be less tender. It also adds a slight acidic or soapy taste if you use too much baking soda, so measure carefully. This replacement is best for recipes where you are already using baking soda or baking powder, not for recipes that rely entirely on eggs for lift.

Cornstarch and arrowroot powder for binding in savory dishes

In savory recipes like veggie burgers, meatballs, or fritters, cornstarch or arrowroot powder can bind ingredients together. Use 1 tablespoon of cornstarch or arrowroot powder mixed with 3 tablespoons of water to replace one egg. Let it sit for a minute to thicken, then mix it into your other ingredients. These starches are flavorless and work well when you do not want any taste change.

Cornstarch and arrowroot powder do not add moisture the way eggs do, so your patties or meatballs may be slightly drier. If the recipe feels too dry after mixing, add a tablespoon of water or oil. These replacements work best in recipes with other wet ingredients like sauces, broths, or oil. They are less useful in dry recipes like breadcrumbs-based meatballs where eggs are doing most of the moisture work.

Commercial egg replacers and when to use them

Commercial egg replacers are powders made from starches, gums, and leavening agents. Brands like Bob's Red Mill Egg Replacer are sold in most grocery stores. Follow the package directions, which usually call for mixing the powder with water. Most commercial replacers work as both a binder and a leavening agent, making them versatile for many recipes.

Commercial egg replacers are convenient and consistent, but they cost more than flax seeds or applesauce. They also contain additives that some people want to avoid. They work well in recipes where you want a result as close to the original as possible, especially in cakes and muffins. Read the package to see whether the replacer is designed for binding, leavening, or both, because not all brands work the same way.

Common mistakes when replacing eggs

The biggest mistake is using the same replacement for every recipe. A flax egg works in a chocolate chip cookie but will make a sponge cake flat and dense. Before you swap, think about what the egg is doing in that specific recipe. If you are not sure, look for a recipe designed without eggs rather than guessing at replacements.

Another common mistake is not adjusting other ingredients. If you use applesauce instead of an egg, you are adding sugar and moisture, so you may need to reduce the sugar in the recipe or add a bit more flour. If you use aquafaba, you are adding liquid, so you may need to reduce other liquids slightly. Small adjustments make a big difference in how the final recipe turns out.

A third mistake is expecting the result to taste and feel exactly like the original. Egg replacements work, but they change the texture and sometimes the flavor. A cake made with applesauce will be moister and denser than one made with eggs. A meringue made with aquafaba will have a slightly different mouthfeel. Accept that the result will be different, not worse—just different.

Frequently Asked Questions

Can I use oil or milk instead of an egg?

Oil and milk do not replace eggs well because they do not bind ingredients together the way eggs do. Oil adds fat but no structure, and milk adds liquid but no binding power. In a recipe where eggs are mainly adding moisture, you could use a bit more oil or milk, but you would also need to add a binder like cornstarch or flax. It is usually easier to use one of the replacements listed above.

What if I only have one egg replacement on hand?

If you only have applesauce, try it in any recipe except one that needs serious rise (like angel food cake). If you only have flax seeds, grind them and use them in cookies or brownies. If you only have baking soda, use it in quick breads or pancakes. Most single replacements work in at least some recipes, so check what you are making before you give up.

Do egg replacements work in savory recipes like quiches or frittatas?

Not well. Quiches and frittatas rely on eggs for their texture and structure, and no replacement truly mimics that. Cornstarch or arrowroot can help bind a savory pie filling, but the result will not be the same. If you need a quiche-like dish without eggs, look for a recipe designed that way, such as one using tofu or a custard made with coconut milk.

How do I know which replacement to use if a recipe calls for multiple eggs?

If a recipe calls for three or more eggs, the eggs are probably doing most of the work, and a replacement may not work well. If it calls for one or two eggs, you can usually replace them. For two eggs, you could use two flax eggs, or one flax egg plus 1/4 cup of applesauce, depending on what the recipe needs. Experiment with one recipe at a time rather than trying a big batch.

Can I mix different egg replacements in one recipe?

Yes. In a cake that calls for two eggs, you could use one flax egg for binding and 1/4 cup of applesauce for moisture. This often works better than using the same replacement twice. Just keep track of what you are adding so you can repeat it if it works well. Write down the replacements you used so you remember for next time.
