Whole30 Coconut Oil Mayonnaise

This Whole30 coconut oil mayonnaise is a must for any Whole30. Made with fractionated coconut oil (also known as liquid coconut oil), this Whole30 condiment recipe makes an MCT oil mayonnaise that tastes creamy and delicious! This Whole30 coconut oil mayonnaise is always in our fridge, and it's by far my favorite Whole30 condiment recipe.

Prep Time 1 minute
Cook Time 1 minute
Total Time 2 minutes
Servings 1 cups


  • 1 whole egg
  • juice of 1/2 lemon about 1/2 tablespoon
  • 2 teaspoons mustard powder
  • 1-2 medium cloves garlic peeled and smashed
  • 1 cup fractionated coconut oil also known as liquid coconut oil
  • Kosher salt



  1. Place all ingredients in the jar that just fits the head of your immersion blender - if your immersion blender came with a jar, that's perfect. The size of the jar is important, though: the circumference of the jar must be only slightly larger than the head of the blender (letting it fit at all) and the mixture must reach the blades. Let ingredients settle for a few seconds.
  2. Place head of immersion blender down into the mixture, at the bottom of the jar. Turn on high speed. Do not move the head until a white, creamy, thick mayo forms at the bottom by the head - this will take a few seconds. Begin to slowly tilt and lift the immersion blender in order to emulsify all the oil; turn the blender off and use the head to push down the oil at the top if necessary. When all oil is emulsified, remove blender and season with salt to taste.
