Top 5 Keto-Friendly Egg Substitutes

Whilst eggs are healthy and versatile, many people choose to avoid eggs. Whether you’re vegan or eggs just don’t agree with you, there are plenty of egg replacers perfect for cooking or baking. Following a keto or low-carb dietandnot eating eggs is an even larger can of worms! Luckily, we’ll be covering all things keto-friendly egg replacers - how to make them, which are best and how keto-friendly they are!

Eggs: The Basics

Eggs are used in cakes, meringues, cookies, brownies, pancakes - the list goes on! Eggs are in many baking recipes for a reason - their role is to thicken, build volume, stabilise, emulsify and provide distinct flavours. We can reduce this into three key roles:

  • Moisture - Provide and maintain moisture in a mixture
  • Structure/binding - Helps a mixture stay bound together and hold its shape
  • Leavening - Helps a mixture rise 

Eggs can have one or all of these roles in a recipe, it all just depends on the other ingredients and what gap needs to be filled in order to get to that baked treat. Most bakes like cakes or cookies need eggs for a similar reason. 

Using a good egg replacer depends on why the egg is needed in the recipe. In other words, make sure you’re using a substitute that fulfils the egg’s role. For example, cakes tend to need an agent that provides moisture, structure and leavening. So you’ll need an egg replacer that ticks all of these boxes. We’ll get on to discussing the role of each egg replacer and which bake it’s best for below!

Let’s crack on with discussing egg replacers, in order of most to the least recommended options.


Flax Seed Eggs

Flax eggs are the perfect egg substitutes to help mixtures bind together. Flax eggs can be made with the bog-standard flax seed meal, which will add an earthy flavour to your bakes. If you want a more neutral, subtle flavour, then we recommend using golden flaxseed meal. 


How to Make Flax Eggs

The perfect ratio is important to make your flax seeds eggy. To make one ‘egg’, you’ll need a 1:3 ratio of flaxseeds to water. In other words:

1 egg = 1 tbsp of flax meal : 3 tbsp of water

From here on out, it’s a pretty easy process!

  1. Whisk together the flax seed meal and water. 
  2. Refrigerate the mixture for at least 15 minutes. This will let the watery mixture get  thicker. 
  3. All done! Add to any recipe requiring regular eggs.

Flax eggs will last 1-2 days in the fridge, or you can freeze them for 3-4 months.

How Keto-Friendly are flax eggs?

Difference in nutritional value to eggs:

Large chicken egg: 77 calories, 0.6g net carbs

Flax egg: 55 calories, 0.2g net carbs

You read that right, with these flax eggs you have a bit more wiggle room with your daily carb intake! 


Don’t Use Flax Eggs When Making:

  • Recipes that need whipped egg whites for structure, such as soufflés.
  • Flourless recipes - you need some form of flour-like ingredients in the recipe to enable the flax seeds to bind the dry ingredients.
  • Dishes with actual eggs as the main ingredient, including a frittata or omelette.
  • Light and airy bakes that need eggs to do more than just bind ingredients - flax eggs can make things like cakes and pancakes dense as they don’t act as a leavening agent.

When to Use Flax Eggs

All in all, flax seeds work well for binding, though they get a bit of stage fright pretending to be the star of the show. Feel free to use them in denser bakes such as keto cookies or brownies! If there are other ingredients in the recipe that act as leaveners, then you can go ahead and replace all eggs with flax seeds. 


Chia Seeds

Chia seed eggs are similar to flax eggs, with the only difference being that they contain chia seeds. The texture, appearance andnet carbs of chia eggs also differ from flax eggs.


How to Make Chia Eggs

To make chia eggs, you can use the exact same ratio as flax seed eggs.

1 egg = 1 tbsp of chia seeds : 3 tbsp of water

Use the same method as flax eggs and be sure to let this mixture sit for around 5-15 minutes to let the mixture thicken.

Don’t like the texture of Chia seeds? Well you won’t feel the texture of chia when only substituting one or two eggs. But if you don’t like the small seeds showing up in your dishes then you can grind them before adding to water.


How Keto-Friendly are Chia Eggs?

Here’s the difference in nutritional value to eggs:

Large chicken egg: 77 calories, 0.6g net carbs

Chia egg: 58 calories, 0.8g net carbs

Yes chia eggs have slightly morenet carbs then actual eggs and flax eggs, which is why they’re less recommended than flax eggs but are still a keto-friendly option!


Don’t Use Chia Eggs When Making:

  • Any recipes that require more than 3 eggs, as your recipe might become a little too chia heavy! The multiple chia eggs will do more than just bind and you’ll feel the texture of chia.
  • Dishes with actual eggs as the main ingredient, including scrambled eggs or meringues.
  • Light and airy bakes that need eggs to do more than just bind ingredients - chia eggs can make things like cakes and pancakes dense as they don’t act as a leavening agent.

When to Use Chia Eggs

You can confidently substitute all eggs for chia eggs when baking denser treats such as brownies, cookies or muffins. If you’re baking lighter treats like cakes orpancakes and there are other ingredients in your recipe that act as leaveners, then you can go ahead and use chia eggs. Does the recipe lack a leavener? Combine your own leavening substitute with chia eggs! You can even add a little bit of baking powder and soda to help your pancakes rise!

Worried that other people won’t be fond of the appearance or texture of chia in your baked treats? To keep your dishes less chia-y, we recommend using chia eggs as substitutes in recipes that require no more than two eggs. You can even disguise the appearance of chia seeds by darkening your baking mixture with somecocoa powder!

Baking Soda & Vinegar

Baking soda and vinegar as an egg replacer on keto

Baking Soda & Vinegar is a great leavening agent with ingredients you most definitely have laying around in your kitchen cupboards! 

How to Make Baking Soda & Vinegar Eggs

To make this egg substitute, you can use either white distilled vinegar or apple cider vinegar. 

1 egg = 1 teaspoon of baking soda + 1 tablespoon of vinegar

All you have to do is just mix the ingredients in a small bowl. These ingredients cause a reaction that creates carbon dioxide and water, which is great for making baked treats light and fluffy!


How Keto-friendly are Baking Soda & Vinegar Eggs?

1 tbsp of white distilled vinegar has 0g of net carbs and 1 tbsp of apple cider vinegar has around 0 to 1g of net carbs, depending on which one you buy. Baking soda is also free of net carbs! So, let’s compare properly:

Baking soda & Vinegar egg: 0 calories, 0g - 1g net carbs

Large chicken egg: 77 calories, 0.6g net carbs

Using this egg substitute is a great low-calorie, low-carb option. The exact nutritional information will vary from brand to brand, so make sure to double check the bottle of vinegar you’re using. 

Don’t Use Baking Soda & Vinegar When Making:

  • Recipes with actual eggs as the main ingredient or include just egg whites, including scrambled eggs or meringues.
  • Mixtures that need eggs to do more than just make your baked goods light and fluffy. 
  • Recipes that require more than two eggs. Be sure to only use this substitute to replace one or two eggs, as having more than two tablespoons of vinegar regularly can lead to side effects such astooth enamel erosion from all the acidity.

When to Use Baking Soda & Vinegar

Baking soda & Vinegar is a versatile egg substitute that is perfect for delicate bakes because of its subtle flavour and lifting power! Use Baking Soda & Vinegar as an egg substitute when baking cakes, bread or cupcakes.

We recommend using baking soda & vinegar instead of eggs when bakingcakes or cupcakes. A vinegar-y flavour shouldn’t come through your bakes, but just to be safe, stick to using this substitute in larger mixtures - or at least mixtures with more than three ingredients. The bubbly reaction that gives your bakes that lovely airy & light texture won’t last long, so be quick to put your mixtures straight in the oven!


Greek Yoghurt

Greek yogurt as an egg replacer on keto

Yoghurt can mimic the moisture provided by eggs, acting is an easy egg replacer to help complete many baking ventures. Here’s the straightforward recipe:

1 egg = ¼ cup of yoghurt

Simply dump in the yoghurt to your mixture and you’re good to go! Remember that a plain yoghurt will work better than flavoured as it won’t change the flavour of your recipe. 


How Keto-friendly is Greek Yoghurt?

We recommend using full-fat Greek yoghurt to make sure you’re getting the highest fat content. Simply check nutritional information to double check that there isn’t a diet-threatening amount ofcarbs. You can make life easier by opting for keto-friendly brands asnet carbs can vary between products. Here is the nutritional information for one Greek yoghurt egg when using a ¼ cup of plain whole milk Greek yoghurt:

Greek yoghurt egg: 31 calories, 1.28g net carbs

Large chicken egg: 77 calories, 0.6g net carbs

As you can see, the net carbs of Greek yoghurt is higher than a large chicken egg. Whilst this isn’t a huge red flag, it does mean that you have to be careful with how many eggs you’re substituting. Also remember that nutritional information and net carbs will vary from brand to brand, so take some time to find the Greek yoghurt with little to no added sugar. We recommend choosing whole milk, plain Greek yoghurt, or find a keto yoghurt that contains keto-friendlysweeteners.


Don’t Use Greek Yoghurt When Making:

  • Dishes with actual eggs as the main ingredient or include just egg whites, including scrambled eggs or meringues.
  • Baking mixtures that require eggs to act as a leavener or binder. Greek yoghurt is best for adding moisture only!


When to Use Greek Yoghurt

Greek yoghurt is perfect for providing moisture to recipes including cakes and muffins. You can replace all eggs with greek yoghurt if there are other ingredients in the recipe that act as leaveners or binders. Otherwise, use both yoghurt and one other binding or leavening substitute mentioned in this blog!

All in all, Greek yoghurt is very versatile and a keto kitchen stable. If you have any left over, serve yourcake with a dollop of greek yoghurt! 


Aquafaba as an egg replacer on keto

Ever cooked legumes and beans and had a ton of liquid left over? Well that liquid is called Aquafaba and you can use it to replace eggs! It’s the same liquid you’ll find in canned chickpeas or beans. The consistency of aquafaba has a similar consistency to raw egg whites, so it makes sense that this is a common vegan substitute for eggs. 

How to Make Aquafaba Eggs

Aquafaba is a great leavening agent that can replace egg whites. It can also act as a binder to replace whole eggs. You can easily replace eggs with aquafaba by sticking to the following ratio:

1 large egg white = 2 tablespoons of aquafaba

1 large whole egg = 3 tablespoons of aquafaba

A can of chickpeas should be plenty to replace a few eggs, as a can yields around 12 tablespoons of aquafaba.

When using aquafaba as a binder, aka. to replace a whole egg, you can use aquafaba straight out the tin. It is also okay to slightly whip the liquid until foamy - do not properly whip them like egg whites. 

If you’re replacing an egg white, you’ll have to properly whip the aquafaba for between 10 to 15 minutes. You can add ¼ teaspoon of cream of tartar or lemon juice before you start whipping to help the liquid foam up, enabling the aquafaba to whip easier and produce a more stabilised result. It should end up looking similar to the consistency of egg whites. If it seems too watery, then you can thicken up the mixture by simmering it in a pan on low heat until it’s reduced by about 25%.

Aquafaba straight out the tin can be refrigerated for a couple days, though freezing it in cubes is best to help it last much longer.


How Keto-friendly is Aquafaba?

Aquafaba egg: 8 - 15 calories, 1.3g net carbs

Large chicken egg: 77 calories, 0.6g net carbs

Whilst Aquafaba has higher net carbs compared to eggs, it’s not a significant jump and you can easily substitute a couple eggs whilst keeping track of yourmacros


Don’t Use Aquafaba When Making:

  • In recipes requiring both egg yolk & egg white. As whipped aquafaba mimics egg whites, stick to using aquafaba in recipes that call for just egg whites.
  • In recipes where eggs are meant to do more than what aquafaba signed up for! Plain aquafaba is simply a binder, so won’t do much for leavening or adding moisture. Don’t use unwhipped aquafaba where it is needed as a leavener or to provide moisture.
  • Dishes that require actual eggs as the main ingredient, including scrambled eggs or meringues.

When to Use Aquafaba

Unwhipped, aquafaba can work as a binder when baking treats such as cookies orpancakes. The thickness of aquafaba varies across brands, with some being thin and runny and others gelatinous and goopy. When you’re trying to use aquafaba as a binder, it’s best to use the thick and goopy variety!

When whipped into semi-soft peaks, aquafaba is a great whipped egg white substitute - feel free to add this to any recipe calling for whipped egg whites, including marshmallows, meringues or macaroons.
