🔪 How to Make Homemade Keto Mayo

For making homemade low carb mayo, you’ll start by adding fresh eggs along with all the other ingredients to the tall cup that comes with an immersion blender.

With the regular blade attached, place the blender on the bottom and pulse until you see it start to thicken and become creamy.

Then, with the blender still running, gently raise it up and down to thoroughly mix the mayo until well emulsified. Do not raise the stick until you see the egg becoming creamy or the mayo will not come together.

After it has reached the consistency you prefer, taste it to see if you want more salt. If so, add a little in small increments until you get the desired amount that taste right to you.

Tip: If you’re at all concerned about using raw eggs, you can use pasteurized eggs.  While the risk of  illness from eating raw eggs is low, children, the elderly, pregnant women and anyone who has a weakened immune system should avoid eating raw eggs, so please use pasteurized instead.

💡 Tips for Making Mayonnaise

• This is definitely one recipe that I recommend watching my video (in the recipe card) before making it yourself. There is a very specific way that I do it and it works perfectly every time, but you have to follow the steps exactly.
• It is crucial that you first start mixing the egg, which will be down at the bottom, before you lift up the stick. This helps to emulsify the mixture and by slowly lifting up the stick, that allows the oil to slowly get mixed into the egg, keeping it creamy and not soupy.
• If you don’t have an immersion blender, you can use a food processor instead. Just be sure to SLOWLY stream the oil in as you are mixing. You cannot just throw everything in at once and blend, it will never come together and will stay in liquid form. Ask me how I know… yes, I’ve tried it!
• I have some ideas below for different variations of mayonnaise. Just be sure to mix your mayonnaise first, then once it is nice and thick, you can add in the additions.

☑️ Storage Instructions

Place in an airtight jar and store in the fridge for up to a week.

🔄 Substitutions

• You can also use avocado oil instead of light oil, but I would recommend a non-extra virgin avocado oil, otherwise your mayonnaise will turn a pale green color.
• If you don’t have fresh lemon juice, you can use all white wine vinegar or apple cider vinegar instead.

Are There Carbs in Mayonnaise?

There’s only a trace amount of carbs per serving in this homemade Keto mayo. Store bought brands usually have additional carbs from added sugar. Just another great reason to make your own!

Is Mayo Keto Friendly?

Absolutely! In fact, mayonnaise is the top condiment on Keto and low carb diets. And, because it has almost no carbs and is high in fat, it makes an excellent choice for many keto recipes.

Which mayonnaise is keto compliant?

The truth is, most mayonnaise is keto friendly, but more on the “dirty keto” side. This is due to the amount of preservatives that are added to extend the shelf life. Many are unrecognizable and hard to pronounce, which are typically the ones you’d want to avoid.

Which mayonnaise has the least carbs?

Because the main ingredients in mayonnaise are oil and egg, most store-bought brands are very low in carbs, as is this recipe.

Can you freeze mayonnaise?

It’s definitely not recommended. Technically you can and while it will be safe to eat, it will likely separate and have a grainy unpleasant texture.
