What Is Mayonnaise?
Everyone knows about mayonnaise, but what really is it? Mayonnaise is an emulsification of oil, egg, and acid – in our case, lemon. When you add these ingredients to the blender in a certain order and in a certain way, the high-powered action of the blender whips it all together turning it from a liquid into a spreadable solid. You can make this low-carb mayonnaise by hand, but you’ll need a good whisk, a large bowl, and plenty of muscle.
Ingredients
It doesn’t take much to make this keto condiment and you probably already have everything you need!
- Oil – Avocado oil is your best pick, or use olive oil.
- Egg – Use a fresh, whole egg. If you’re worried about using a raw egg, look for pasteurized eggs from your grocery store. They’re less likely to cause any issues.
- Dijon mustard – You can also use any smooth mustard.
- Lemon – Just a wee bit of fresh lemon.
- Salt and pepper – Just a pinch to season it.
You’ll Also Need:
- A blender

Chef Jenn’s Tips
- Use a good quality oil to make mayonnaise. Oil can go rancid if it hasn’t been stored properly or if it is too old.
- Start with 1 tablespoon of lemon juice and add more to taste.
- You can over-emulsify mayonnaise. Don’t over-mix it!
How To Use Keto Mayonnaise
You can use keto mayonnaise just like any other mayo. Use it as a spread on chaffle sandwiches, or use it as an ingredient in dishes like:
- Coleslaw – Cool and creamy!
- Egg Salad – This is my 30+ year tried and true recipe!
- Ham Salad – So creamy, so easy!
- Dill Pickle Ranch – Creamy and tangy!
Storage
Homemade mayonnaise does have raw egg in it, and as such, it should be kept refrigerated. If using fresh eggs, you can keep your mayonnaise in an airtight container in the fridge for about a week.
