Let’s have a little chat about homemade mayo, shall we? It’s all the rave right now, well at least in my kitchen it is! I have never been a huge mayonnaise fan but I have always down for using it in recipes. Now, thanks to making my own mayo, I am like the world’s biggest mayo fan (if you didn’t notice already)! Making your own mayonnaise may sound difficult but that is far from the truth– it is so very simple! Only 5 ingredients, and about 5 minutes and you’ll have your own mayo on the table. For real though!

Homemade Mayo

I CANNOT believe I went my first Whole30 Challenge without homemade mayo…what a disgrace! I was seriously missing out! Making a batch of mayonnaise leads to endless, tasty possibilities. Here are some of my favorite uses of mayo in my kitchen when I am (and when I am not) taking on the Whole30 Challenge: 

  1. Use it in tuna or chicken salads for delicious, easy grab-and-go lunches.
  2. Use it to make salad dressings (You can make Ranch and Ceasar by using Mayo as a base).
  3. Change up the flavor of the mayo to make an Aioli to use as a dipping sauce for roasted french fries, veggies, and for steamed artichokes! You can also drizzle aioli sauces over tacos for an extra umph!
  4. Make a tarter sauce to elevate your everyday fish!

As you can see…the possibilities are pretty much endless here and we will continue to include homemade mayo in our recipes so that you can get more inspiration and use out of yours. Now, GO MAKE SOME MAYO!

Homemade Mayo


  • 1 cup avocado oil or other light-flavored oil
  • 1 large egg must be room temp!

Optional for Mayo Spread

  • 1 garlic clove, minced
  • 1 teaspoon freshly squeezed lemon juice
  • 2 teaspoons mustard powder
  • kosher salt, to taste


Immersion Blender Method:

  • Pour the oil into a wide-mouth glass jar with an opening a little bit wider than the head of your immersion blender. Crack the egg into the oil and let settle unto the bottom of the jar.
  • Place the immersion blender into the jar and position the blade directly over the egg yolk. Turn the immersion blender on low and hold in place, while the blender is running, until the bottom of the jar starts to turn into a creamy emulsion, about 10 seconds.
  • Once you see that creamy emulsion at the bottom, start lifting the blender up a bit and pressing it back down, essentially emulsifying the mixture above the mayo at the bottom, bit by bit, until you reach the top and the entire jar is emulsified.
  • Use as-is as a base for dressings or you can also turn it into an actual mayo by blending in the additional ingredients listed above.

Food Processor Method:

  • If your egg is chilled, place it in a cup of hot or very warm water for 3-5 minutes to bring it to room temp. *YOUR EGG MUST BE AT ROOM TEMP OR YOUR MAYO WILL NOT EMULSIFY*
  • Place room temp egg, the mustard powder, the kosher salt, and 1/4 cup of the oil in a food processor or blender, blend until well combined.
  • Now, for the main event...turn your food processor or blender on and keep that blending as you VERY SLOWLY pour in the remaining 3/4 cup of the oil in. When I say slowly pour, just keep a constant flow going as slow as you can possibly go. The slower you pour, the thicker your mayo will come out! If you pour too quickly, it will not emulsify and you'll just have a sloshy mess.
  • When you are done and you have a beautiful, fluffy mayo; squeeze in the juice of the lemon and pulse one more time to combine.

  1. I tried to make this last night using an immersion blender and it did not emulsify and just looked like a disgusting oily mess. The egg was room temperature. What did I do wrong?

      1. Homemade Mayo lasts about 5 to 7 days in the fridge; however, check your egg expiration date and ensure that doesnt come sooner!

  2. The rule of thumb is that the Mayo is good to the life of the egg. When you would have thrown out the egg, do the same with the Mayo.

  3. Curious what you use to store your homemade condiments in? Any other food storage tips for the food you prep weekly?

    1. For me, No, I am not afraid of salmonella. The choice is yours. Feel free to Google “salmonella risk” and make the judgment call for yourself. 🙂

  4. Do you have recommendations for other compliant oils to use in your homemade mayo? Would olive oil or avocado oil work the same?

    1. Hi Katie,
      The best other oil to use other than Safflower in my opinion is “light” olive oil… not “extra virgin” (it’s too heavy in flavor).
