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!
