Ingredients for Making Homemade Keto Mayonnaise:
- 2 Eggs
- 2 tablespoons of Dijon Mustard
- 7 ounces of Macadamia Oil
- 20 ounces of Light Extra Virgin Olive Oil

How To Make Keto Mayonnaise:
- Place the eggs and mustard into your food processor and blend on medium speed for 3 minutes, until well combined.

I love this mayonnaise, I didn’t have macadamia so used walnut oil instead.. same macros! Absolutely delicious will make again, maybe try avocado oil thank you!
Doesn’t eating the raw egg kinda turn anyone else off? I really want to make my own, but I can’t get over it…lol
I hate to be the bearer of bad news, Jasmynn, but all the whole egg mayonnaise at the supermarket contain raw eggs. Most mayonnaise, excluding the super processed or vegan ones, contains raw egg yolks at the very least.
There’s a very good chance you’ve been eating it for a long time without realizing, why not take the plunge and try making your own 🙂
I use raw egg blended into my coffee every morning….with a little vanilla and collagen powder. Never gotten sick. Age 64 and been doing this over 5 yrs.
Instead of macadamia oil, can I use all light olive oil?
You sure can.
How about flax seed oil?
Hi Sarah,
Flaxseed oil has a very overpowering flavor, if that is something you enjoy, you are welcome to use it. Personally I’m not a fan, so I wouldn’t recommend it.
