5-minute Whole30 Mayo

Mayo seems daunting to make, I get it! But it can be a budget game changer. Often people will say, “I don’t eat much mayo,” but I use it to make tuna and chicken salad #cheapproteinoptions, as well as use it as a base for three inexpensive #whole30compliant dressings.

5-minute Whole30 Mayo


  • 1 egg
  • 1 cup light tasting olive oil
  • 1 tablespoon lemon juice
  • 1 pinch salt
  • 1 squirt mustard
  • Immersion Blender*


  1. Put all ingredients in a mason jar, making sure the mouth of the jar is slightly bigger than your immersion blender. Put immersion blender in the jar of ingredients, waiting a moment to let ingredients separate after doing so. 

  2. Holding blender down at the bottom of the jar, turn on blender. Once you see the mayo forming, slowly pull blender up towards the top of the jar. Move blender up and down through the jar a few times. And voila!

Recipe Notes

*You have to have an immersion blender for this mayo. But, I have never had this mayo not turn out while using an immersion blender...but totally have failed multiple batches just using a mixer. The immersion blender only costs about $15 at Walmart or on Amazon and is worth the investment!

This ends up being about $2/cup (depending largely on the price of your olive oil), whereas the store-bought Primal Kitchen Whole30 mayo (which is delicious but pricey!) is usually around $6-7/cup. That’s a big difference!

    I made this today and it came together beautifully. I didn’t have light flavored olive oil on hand, only EVOO and the taste was a little heavier than I had wanted. But! It was still delicious and easy to make. I will definitely use the recipe again.

  2. Love your site,,,love your recipes…

    How many days will homemade mayo stay good in the refrigerator?

    • Thank you so much, happy you enjoy them!

      The mayo is generally good for as long as the eggs you used in them (look at the expiration date on your egg carton). For me that’s usually at least 2 if not 3 weeks.

  3. What kind of olive oil do you use? What do you mean light tasting. There seem to be so many types! Also, I don’t have an emersion blender. Are there any other options?

    • If you look in the oil section of most grocery stores, you should be able to find one that is specifically labeled “light tasting” or “extra light tasting.” It will still work with regular olive oil, I just don’t love the heavy olive taste of it personally. You can make this in your blender or kitchen aid by combining all ingredients and, while mixer or blender is running, verrrrry slowly adding the olive oil until it emulsifies (thickens). But, I found many have a hard time with that method as it’s easy to do wrong and end up with an oily mess. The immersion blender is affordable (usually around $15) and worth it for me to have a consistent successful result : ).

    So glad I purchased an immersion blender to make this! I cannot believe how easily and quickly it came together. One of my least favorite things about doing Whole30 was the cost of compliant mayo and other sauces. Thanks for this great recipe!!

    • I’m so happy this felt so easy and doable for you! I agree, condiments on Whole30 can be so pricey and making them yourself is so affordable. Making your own mayo is a super power – good for you!
