Eggs are hard to replace in some dishes, especially when they are the star, like in omelets or quiches. You’re probably better off cooking something else.
But if you're baking, and eggs aren’t the main ingredient, many other foods can work in place of an egg. They include:
Egg replacements. That’s not the same as egg substitutes. Egg substitutes can contain egg.
Applesauce. One-fourth cup is a common substitute for one egg in a baking recipe.
Banana. Half a mashed, ripened banana can work in place of one egg.
Mixtures (below) can take the place of 1 to 3 eggs, such as:
- 1 tablespoon water, 1 tablespoon vinegar, 1 teaspoon baking powder
- 1 teaspoon yeast dissolved in 1/4 cup warm water
- 1 1/2 tablespoons water, 1 1/2 tablespoons oil, 1 teaspoon baking powder
- 1 packet gelatin, 2 tablespoons warm water (mix just before using)
- 1 tablespoon ground flaxseed mixed in 3 tablespoons warm water
Keep in mind that egg replacements may not be as fluffy and light as actual eggs.
