Creamy Homemade Keto Mayonnaise Recipe

Nothing beats easy homemade mayonnaise. It’s a perfect keto-friendly condiment without the hidden sugars found in many store-bought varieties.

Once you start making your own, you’ll likely never want the bland, preservative-filled white slop from supermarket jars again. Homemade mayonnaise contains wholesome ingredients, good oils, and protein — and you control exactly what goes in. It takes a little practice to master the technique, but it’s straightforward and rewarding.

Making Homemade Mayonnaise

I now make mayonnaise weekly with an electric whisk and can easily whip up a batch. The key is to add the oil very slowly while whisking so the mixture emulsifies. The choice of oil greatly affects the flavor: light grapeseed or light olive oil gives a delicate taste, while avocado oil offers a richer, buttery note if you can find it affordably. Using lemon juice instead of apple cider vinegar, or varying the type of oil, will change the final flavor profile, so experiment until you find your favorite.

Once you have a basic mayonnaise, you can customize it with seasonings: garlic or garlic powder for savoury depth, lemon zest or juice for brightness, or fresh herbs like basil or dill for a more aromatic mayonnaise. Small additions can transform the condiment into a dip, spread, or dressing tailored to whatever you’re serving.

Ingredients

  • 1 egg yolk
  • 1 teaspoon Dijon mustard
  • 2 teaspoons apple cider vinegar or lemon
  • 200 ml light olive oil
  • ½ teaspoon salt adjust to taste

Instructions

  1. Place the egg yolk in a bowl, add the Dijon mustard and a drop of the oil. Whisk until smooth — an electric whisk works well.
  2. Slowly add the oil while whisking. Start drop by drop until the mixture begins to emulsify, then continue adding the oil gradually until it’s all incorporated.
  3. Add the apple cider vinegar (or lemon), season with salt and pepper, and whisk until fully combined.
  4. Taste and adjust: add more vinegar/lemon, mustard, salt, pepper, or a pinch of garlic powder to suit your preference.
  5. Store the mayonnaise in a sealed jar in the refrigerator.
