Keto Mayonnaise
When you first started your Keto diet, how exciting was it to realize that you no longer needed to feel guilty about eating fats like butter and mayonnaise? If you’re like me, you quickly started using these two ingredients in EVERYTHING.
Before long, I found myself wondering how hard it would be to whip up my own mayo right at home. That’s when I created this recipe for a super easy homemade Keto mayonnaise!
This recipe couldn’t be simpler. In fact, the only trick is to add the oil very slowly while blending. As long as you don’t rush it, the mayo will turn out perfectly every time.
So, why should you make your own mayonnaise? After all, isn’t mayo considered a pretty Keto-friendly ingredient anyway?
The answer, as usual, comes down to the ingredients. Many store-bought brand of mayonnaise include added sugar, unhealthy oils, preservatives, and other unwanted ingredients. No thanks.
Meanwhile, the brands that DO make clean mayo tend to come with quite the price tag. It’s ridiculous what you have to pay for quality food sometimes.
That’s why I recommend ditching the unhealthy ingredients, saving yourself some money, and making this super easy Keto mayo right at home! Trust me, you’ll never want to buy mayo from the store again.

Variations For Your Keto Mayo
Sunflower oil is a great oil to use in recipes that don’t require heat, like cold sauces or dressings. However, if you’re an olive oil lover, you could replace ⅓ cup of sunflower oil with ⅓ cup of olive oil.
Want to add a little flavor to your mayo? Make a garlic aioli mayonnaise! Just add one clove of minced garlic along with the egg, mustard, lemon juice, and salt, then follow the rest of the recipe like usual.

What To Eat With Keto Mayonnaise
I think the better question is what CAN’T you eat with mayo? There are SO many ways to put this easy recipe to great use!
For example, I love using it in the filling of these Keto stuffed avocados. It’s like a double-whammy of healthy fats.
It would also be perfect for these Keto chicken salad snacks. Of course, you can always skip the fathead puff pastries and just whip up a big batch of traditional chicken salad.
For a delicious brunch or snack, try using Keto mayo in my Spicy Deviled Eggs recipe. You can also follow steps 1-8 to hard boil and peel the eggs, then chop them up, mix with some mustard and mayonnaise, and enjoy an easy egg salad.
Finally, one of my favorite uses for homemade mayo is as a base for sauces or dressings. Keto copycat Chick-Fil-A sauce and Thousand Island Dressing are two perfect examples!
Basically, wherever you’d normally use mayo, you can use this low-carb, sugar-free mayo instead. It’s that simple.

How To Store Keto Mayo
Because we aren’t using any preservatives, your homemade mayo won’t last in the fridge for years like some of the store-bought stuff. But that’s okay! Real food isn’t SUPPOSED to last forever.
You can store this sugar-free mayo in an airtight container in the refrigerator for up to a week. I usually make a batch as part of my Sunday meal-prep to enjoy throughout the week. Trust me, I never have a problem using it all!

How To Make Keto Mayonnaise
In a tall container that is suitable for use with an immersion blender, add the egg, mustard, lemon juice, and salt.

Pulse the blender while very slowly adding the oil. Be sure to lift the blender several times to let air inside the mixture.

Continue to blend for a few minutes as the mixture thickens. If the mayonnaise is still runny, very slowly add more oil and continue to blend.
