Learn what a flax egg is, how to make it and when you should use it! Using a flax egg is a great substitute if you don’t have eggs on hand, want to make an allergy friendly recipe, or for vegan baking.

Have you ever started to make a recipe, only to realize you are out of eggs?  This happened to me recently when I was making some Healthy Peanut Butter Banana Muffins for my toddler.  Luckily, I was able to substitute a flax egg for the egg called for in the recipe.

What is a flax egg?

A flax egg is an egg substitute that is made from ground flax seeds and water.  A flax egg is vegan, gluten free, paleo and whole 30.  Not only is it great for people with allergies or food restrictions, but it also works well as a substitute for when you run out of eggs!

How does a flax egg work?

When the ground flax seeds are mixed with water, the mixture becomes gelatinous, thanks to a gum that is in the seed coating.  This mixture can bind and emulsify ingredients in baking recipes like an egg would.

What recipes can I use a flax egg in?

Flax eggs work best in these kinds of recipes:

  • muffins
  • pancakes
  • quick breads
  • cookies

What can I use instead of a flax egg?

If you need an egg substitute but you don’t have flax seed, you can also make something similar using chia seeds.  Mixing 1 TBSP chia seeds with 3 TBSP water will give you another option for an egg substitute.

You can also use the following in some recipes as an egg substitute

  • 1/4 cup apple sauce
  • 1/4 cup mashed banana
  • 1/4 cup pumpkin puree
  • 1/4 cup mashed avocado
  • 1/4 cup silken tofu
  • 1/4 cup yogurt
  • 3 TBSP creamy nut butter

  1. Meghan, this recipe comes at the perfect time for me because I’ve been making more vegan friendly recipes lately! I have yet to try using a flax egg substitute, but have always wanted to so I’m definitely going to have to give this a try!
