The most common egg replacements depend on what you're making

The substitute you choose depends on whether you're baking a cake, making a binding sauce, or cooking scrambled eggs—each uses eggs differently, so one replacement won't work for everything. For baking, applesauce, mashed banana, or commercial egg replacer work well because they add moisture and help bind dry ingredients together. For binding meat or vegetables, aquafaba (the liquid from canned chickpeas) or ground flaxseed mixed with water creates a gel that holds things together. For cooking, tofu or chickpeas can replace eggs in scrambles and fried rice, though the texture will be different.

The reason this matters: using applesauce in a quiche will make it soggy, and using aquafaba in a cake will make it dense. This guide walks you through which substitute works for which cooking task, how much to use, and what to expect from the result.

Key Takeaways

  • Applesauce and mashed banana work best in cakes, brownies, and quick breads where moisture is already part of the recipe.
  • Aquafaba (chickpea liquid) and ground flaxseed create a gel that binds ingredients together, making them useful for meatballs, veggie burgers, and baked goods that need structure.
  • Silken tofu and crumbled firm tofu can replace scrambled or fried eggs in savory dishes, though the flavor and texture will be noticeably different.
  • Commercial egg replacer powders are formulated to mimic eggs in most baking situations and work in a wider range of recipes than single-ingredient swaps.
  • The amount you use matters: one egg is not the same as one-quarter cup applesauce in every recipe, and some substitutes work better in certain ratios.

Applesauce and mashed banana for cakes and brownies

Use one-quarter cup of unsweetened applesauce or mashed banana to replace one egg in cakes, brownies, muffins, and quick breads. These work because they add moisture and a binding agent called pectin, which helps hold the batter together as it bakes. The result will be slightly denser and more moist than a traditional cake, and the crumb will be tighter.

Applesauce is neutral in flavor, so it won't change the taste of chocolate or vanilla cakes. Banana adds its own flavor, which works well in chocolate, spice, and vanilla cakes but will be noticeable in delicate flavors like lemon or almond. If you're using banana, reduce the liquid (milk or water) in the recipe by two tablespoons per egg replaced, because banana adds more moisture than applesauce does.

Do not use applesauce or banana in recipes where eggs are the main structure—custards, meringues, or angel food cakes will fail. These recipes need the protein in eggs to create their specific texture, and fruit puree cannot do that.

Aquafaba and flaxseed for binding and structure

Aquafaba is the liquid you drain from a can of chickpeas. Use three tablespoons of aquafaba to replace one egg in recipes where you need binding power: meatballs, veggie burgers, baked goods that need a sturdy crumb, and some cookies. Aquafaba contains starches and proteins that mimic what eggs do when they set during cooking.

Ground flaxseed works similarly: mix one tablespoon of ground flaxseed with three tablespoons of water and let it sit for five minutes until it becomes gel-like. Use this mixture to replace one egg. Flaxseed adds a slightly nutty flavor and works well in whole-grain breads, oatmeal cookies, and savory baked goods. It does not work well in delicate cakes or anything where you want a light texture.

Both aquafaba and flaxseed create a denser result than eggs do. Cookies will be chewier, cakes will be heavier, and meatballs will be slightly more compact. This is not a flaw—it's just different. If you're making chocolate chip cookies or brownies, the difference is barely noticeable. If you're making a sponge cake, it will be obvious.

Silken tofu for scrambled eggs and fried rice

For scrambled eggs, use one-half cup of crumbled silken tofu to replace two eggs. Silken tofu is soft and creamy, so it mimics the texture of cooked eggs better than firm tofu does. Crumble it into a hot, oiled pan and cook it for three to four minutes, stirring often. Add salt, pepper, and any seasonings you would use in regular scrambled eggs—turmeric for color, nutritional yeast for a savory flavor, or fresh herbs.

The result will look similar to scrambled eggs but will be softer and will not brown the way eggs do. If you want color and a slightly crispy edge, cook it a bit longer and use higher heat, though it will never get as firm as cooked egg white.

For fried rice or stir-fries, use the same amount of crumbled firm tofu instead. Firm tofu holds its shape better when you stir it around the pan. Cook it separately in a little oil until the edges are golden (about five minutes), then add it to your rice or vegetables at the end. This gives you texture and protein without the egg flavor.

Commercial egg replacer powder for most baking

Brands like Bob's Red Mill Egg Replacer and JUST Egg are powders designed to work in place of eggs across many recipes. Follow the package directions—most call for mixing the powder with water to create a slurry. Typically, one egg equals one-quarter cup of water mixed with the amount of powder listed on the box (usually around three tablespoons).

These products work in cakes, cookies, muffins, and some savory baked goods. They are more reliable than single-ingredient swaps because they are formulated to mimic eggs' binding, leavening, and moisture-holding properties all at once. The result is closer to a traditional baked good than applesauce or banana will give you.

The downside is cost—egg replacer powder is more expensive per use than applesauce or a banana. It also requires you to have the product on hand. If you bake occasionally and already have fruit in your kitchen, applesauce is a cheaper first choice. If you bake regularly or need consistent results, egg replacer powder is worth buying.

Cornstarch and arrowroot for thickening sauces

If you're using eggs to thicken a sauce or custard—like in hollandaise, béarnaise, or pastry cream—eggs are doing two jobs: adding richness and creating a thick, smooth texture. Cornstarch or arrowroot powder can replace the thickening function, though not the richness.

Mix one tablespoon of cornstarch or arrowroot with two tablespoons of cold water or milk to make a slurry. Add this to your sauce while it simmers, stirring constantly. Cook for one to two minutes until the sauce thickens and becomes clear. This works for gravies, pan sauces, and straightforward custards. The sauce will be thick and smooth but will not have the creamy mouthfeel that egg yolks provide.

For richer sauces where you need both thickening and creaminess, use a combination: cornstarch for thickening plus a splash of cream or coconut milk for richness. This gets you closer to what eggs would have done.

What to expect: texture and flavor changes

Every egg replacement will change your final dish slightly. Applesauce and banana make baked goods moister and denser. Aquafaba and flaxseed create a chewier texture. Tofu in scrambles is softer and less firm. Cornstarch sauces lack the richness of egg-based ones. None of these is wrong—they're just different.

The most noticeable change happens in recipes where eggs are the star: custards, meringues, soufflés, and angel food cakes. These recipes depend on eggs' unique protein structure, and no single replacement can fully replicate it. For everyday baking and cooking—cakes, cookies, meatballs, scrambles, and sauces—the replacements work well and most people won't notice a significant difference.

Start with a recipe you've made before so you know what the original should taste like. This makes it easier to judge whether the replacement worked. If you're trying a new recipe for the first time, you won't have a baseline to compare against, and you might blame the egg replacement for something that's actually just how that recipe turns out.

Common mistakes when replacing eggs

The biggest mistake is using the same amount of replacement as you would eggs. One egg is not the same volume as one-quarter cup of applesauce. Measure carefully and follow the ratios given for each replacement. If a recipe calls for two eggs and you use two cups of applesauce, your cake will be a puddle.

Another common error is using the wrong replacement for the job. Applesauce in a quiche makes it soggy. Aquafaba in a delicate cake makes it heavy. Tofu in a batter makes it gummy. Match the replacement to what eggs are doing in that specific recipe—binding, leavening, adding moisture, or creating structure.

Finally, don't expect the first try to be perfect. Baking is sensitive to small changes, and switching from eggs to a replacement means your recipe will behave slightly differently. You might need to adjust oven temperature by 25 degrees, bake a few minutes longer, or add a tablespoon more flour. Keep notes on what you change so you can repeat what works.

Frequently Asked Questions

Can I use oil instead of eggs?

Oil adds moisture but not binding power, so it works only in recipes where eggs are mainly adding fat—like brownies or very moist cakes. Use one-quarter cup of oil per egg. In recipes where eggs bind ingredients together (meatballs, veggie burgers, some cookies), oil alone will not work; you need aquafaba, flaxseed, or egg replacer powder.

What's the difference between silken and firm tofu for cooking?

Silken tofu is soft and creamy, making it better for scrambled eggs and blended dishes. Firm tofu holds its shape when you stir it, making it better for fried rice, stir-fries, and any dish where you want distinct pieces. Do not use firm tofu for scrambled eggs—it will be too chunky and won't have the right texture.

Do I need to change the oven temperature when I use an egg replacement?

Usually no, but some replacements bake slightly faster or slower than eggs do. If your baked good is browning too quickly on top, lower the temperature by 25 degrees. If it's taking much longer to bake through, raise it by 25 degrees. Check for doneness a few minutes earlier than the recipe suggests, since timing can shift.

Can I use mayonnaise as an egg replacement?

Mayonnaise is mostly oil and eggs, so it won't help you avoid eggs. It also adds a strong flavor that will change your recipe. If you're avoiding eggs for dietary reasons, mayonnaise won't work. If you're just out of eggs, it can add moisture to a cake, but use only one-quarter cup per egg and reduce other liquids slightly.

What if my baked good turns out dry when I use a replacement?

You likely used too little liquid or too much flour. Egg replacements often need slightly more liquid than eggs do. Add one to two tablespoons of milk or water to your next batch. Also check that you're measuring flour correctly—scoop and level, don't pack it down. If the problem persists, try a different replacement; applesauce and banana add more moisture than aquafaba or flaxseed do.
