A flax egg (or flaxseed egg) is a vegan egg substitute for baking. It’s just ground flax meal mixed with water, and takes 5 minutes to make. Even if you’re not vegan, you can use flax eggs as an egg replacement for baking in a pinch when you run out of eggs. Learn how to make a flax egg with the perfect flax egg ratio in this post.


  • 1 tbsp ground flax seed (flax meal)
  • 2 1/2 tbsp water


  1. Add the ground flax seed and water to a small bowl.
  2. Use a small whisk or a spoon to thoroughly mix it together for 15-30 seconds.
  3. Let the mixture sit for 5 minutes.
  4. Stir well again. The mixture should be a gelatinous consistency, similar to that of raw egg.
  5. If not fully gelatinized, let the mixture sit for another 5 minutes.
  6. Use as a vegan egg substitute in baking recipes.


How to grind flaxseed

There are a few kitchen tools you can use to grind flaxseed into flax meal:

For this particular recipe, I used a NutriBullet blender and it worked perfectly.

To make flax meal, just add whole flaxseeds to a food processor, blender, spice grinder, or coffee grinder. Grind it up until powdery.

When not to use flax eggs in recipes

While flax eggs are a good vegan egg replacement in many baking recipes, there are times when you should avoid using flax eggs as an egg substitute. Regular chicken eggs are best for:

  • Any egg recipe, such as scrambled eggs or omelettes.
  • A baking recipe with whipped egg whites, like meringue or macarons.
  • Recipes where egg is used for a coating, like French toast.
  • A baking recipe or dessert recipe where eggs are a key ingredient, like custard, mousse, or souffle.

Can I use chia seeds instead of flax?

Yes! Chia seeds are another ingredient you can use to make a vegan egg substitute for baking. To make a chia egg, mix 1 tablespoon of chia seeds (either whole or ground) with 2 1/2 tablespoons of water. Let the mixture sit for 5-10 minutes to gel.
