Plant-Based Diet: Exploring Egg Substitute Options

Eggs are a versatile and essential ingredient in many recipes, contributing to texture, flavor, and binding properties. However, for vegans, those with egg allergies, or when you simply run out of eggs, finding suitable substitutes is crucial. Fortunately, numerous plant-based alternatives can replicate the functions of eggs in both sweet and savory dishes.

Understanding the Role of Eggs in Cooking

Before diving into the substitutes, it's important to understand the various roles eggs play in recipes:

  • Binding: Eggs help combine ingredients and hold them together.
  • Leavening: Eggs trap air pockets in foods, causing them to expand during heating. This helps foods puff up or rise.
  • Moisture: The egg liquid is absorbed into the other ingredients in a recipe.
  • Flavor and appearance: Eggs help carry the flavors of other ingredients and brown when exposed to heat.
  • Emulsifying: Eggs contain compounds that bind to both oil and water, stabilizing ingredients that would otherwise separate.
  • Flavor: Sulfur-containing amino acids in egg whites contribute to the characteristic "eggy" flavor.
  • Humectant: Eggs help retain moisture in baked goods.
  • Mouthfeel: Eggs influence the texture of food, contributing to smoothness, chewiness, firmness, and other sensory attributes.
  • Appearance: Carotenoids in egg yolks enhance the color of food.

Knowing which properties eggs provide in a specific recipe is key to successful substitution.

Best Egg Substitutes for Baking

Here's a detailed look at some of the most effective egg substitutes for baking:

1. Aquafaba

Aquafaba is the liquid from a drained can of chickpeas. Its high protein, starch, and fiber content make it an excellent plant-based emulsifier and foam stabilizer. It can be whipped until foamy or soft peaks form, mimicking egg whites.

  • Substitution: 3 tablespoons of aquafaba = 1 egg
  • Best for: Meringues, vegan Eton mess, ginger & marmalade roulade, and recipes calling for egg whites.
  • Pros: Impressive egg white substitute.
  • Cons: May not work if you need the richness of a yolk.

2. Ground Flaxseed

A flax egg is a popular vegan baking substitute made by combining ground flax seeds with water and letting it sit until it thickens. The binding properties of flax seeds make it a great addition to cookies, brownies, and other sweet treats.

  • Substitution: 1 tablespoon of ground flax seeds + 3 tablespoons of water = 1 egg
  • Best for: Cookies, brownies, protein pancakes, vegan chocolate brownies, vegan rhubarb & custard bake, and vegan cherry & almond brownies.
  • Pros: Excellent binder.
  • Cons: Won't add to the rise of cakes; may need baking powder. Can result in a nuttier flavor.

3. Apple Purée

Apple purée adds moisture and binds mixtures together in cakes and bakes. The flavor of apple is subtle, making it a versatile option.

  • Substitution: ¼ cup apple purée = 1 egg
  • Best for: Cakes and bakes where a subtle flavor is desired.
  • Pros: Adds moisture.
  • Cons: May not brown as deeply.

4. Yogurt

Coconut, soya, or Greek yogurt adds moisture and helps bind ingredients together, giving rich results.

  • Substitution: ¼ cup yogurt = 1 egg
  • Best for: Vegan birthday cake, vegan carrot cake, and cookies & cream brownies.
  • Pros: Adds moisture and richness.
  • Cons: May need to bake for an extra 10-12 minutes.

5. Mashed Banana

Mashed banana works best in recipes that call for it specifically, as the banana flavor is quite strong.

  • Substitution: ½ banana = 1 egg
  • Best for: Vegan banana bread, vegan banana cupcakes, and vegan banana pancakes.
  • Pros: Adds sweetness and moisture.
  • Cons: Distinct banana flavor.

6. Silken Tofu

Silken tofu can be used in savory or sweet dishes, such as vegan cheesecake or chocolate mousse. It needs to be whipped until smooth to avoid chunks in the mixture.

7. Chia Seeds

Similar to flax seeds, chia seeds can be mixed with water to create a 'chia egg'. The gel-like texture makes it a brilliant binder.

  • Substitution: 1 tbsp chia seeds + 2.5 tbsp water = 1 egg
  • Best for: Chia & oat breakfast scones with yogurt and berries, and vegan gingerbread cookies.
  • Pros: Excellent binder.

8. Coconut Oil

Coconut oil can be used to replace eggs in vegan baking and when breading foods. Be careful not to add too much, as it can result in a greasy bake.

  • Substitution: 1 tablespoon coconut oil = 1 egg
  • Best for: Vegan lemon cake and vegan sticky pear pudding.
  • Pros: Mixes well into batters and bakes.
  • Cons: Can result in a greasy bake if overused.

9. Pumpkin Purée

Pumpkin purée lends itself perfectly to cakes, cookies, brownies, and quick breads due to its sweet flavor, smooth texture, and vibrant color.

Vegan Egg Taste Test

VeganEgg is a 100% plant-based egg replacer. To prepare, use two level tablespoons of VeganEgg plus a 1/2 cup of ice-cold water, whisking vigorously. Vegan eggs take a bit longer to cook than regular eggs and have a slightly paler color. The consistency is similar, and they scramble nicely.

Vegan Egg Nutrition Facts
