What Is a Substitute for Eggs?
QUICK ANSWER
The best egg substitute depends on what the egg does in the recipe. For binding in baking: 1 tbsp ground flax plus 3 tbsp water makes a flax egg. For moisture: 1/4 cup applesauce or mashed banana. For leavening or structure: aquafaba (3 tbsp) or silken tofu work best.
Eggs do multiple things in a recipe (bind, leaven, add moisture, provide structure), and no single substitute handles all four. The right egg replacement depends on what the egg is doing in the specific recipe, which is why a flax egg works in cookies but fails in angel food cake.
What's the best substitute for eggs in baking?
For most baked goods, a flax egg or chia egg is the most reliable substitute. Mix 1 tablespoon of ground flaxseed (or chia seeds) with 3 tablespoons of water, let it sit for 5 minutes until it gels, and use it as 1 egg. This works well in cookies, muffins, pancakes, and quick breads where the egg's main job is binding.
Other options: 1/4 cup of applesauce or mashed banana adds moisture (best for sweet baked goods); 1/4 cup of plain yogurt or silken tofu adds structure; 3 tablespoons of aquafaba (the liquid from a can of chickpeas) replicates egg whites for leavening.
How do you make a flax egg or chia egg?
The ratio is the same for both: 1 tablespoon of ground seed plus 3 tablespoons of water equals 1 egg. Use a small bowl, stir, and let it sit for 5-10 minutes. The mixture thickens into a gel that binds the recipe like an egg. Use whole flaxseeds ground in a coffee grinder or buy pre-ground flax meal. Chia seeds work whole or ground. Both add a slight nutty taste that disappears in most baked goods but might be noticeable in delicate recipes like vanilla cake.
Can you substitute eggs in non-baking recipes?
For binding meatballs, meatloaf, or burgers: use 2 tablespoons of mashed potato, 1/4 cup of soaked oats, or 1 tablespoon of cornstarch plus 3 tablespoons of water per egg.
For coating fried foods (replacing the egg wash in breading): use plant milk thickened with 1 teaspoon of cornstarch, or aquafaba straight from the can. For scrambled-egg-style dishes: silken tofu seasoned with turmeric and kala namak (black salt) provides the closest egg flavor and texture.
When can't you substitute eggs?
Recipes that rely on eggs for structure usually fail with substitutes. Angel food cake, sponge cake, meringues, custards, and souffles need real egg whites or yolks to work. The protein structure of beaten eggs creates the rise and texture that no substitute matches.
For these recipes, aquafaba comes closest (it whips into peaks similar to egg whites), but the result is usually less stable. For custards specifically, no substitute matches the smooth set you get from real eggs.
The best egg substitute depends on what the egg is doing in the recipe. Flax and chia eggs handle binding, applesauce or banana adds moisture, aquafaba mimics egg whites for leavening. For structural recipes (meringues, custards), substitutes usually fall short.
