Ingredients for Homemade Keto Mayonnaise

This homemade mayo keto recipe uses simple pantry staples:

  • 1 large egg, room temperature
  • 1 tablespoon lemon juice or white vinegar
  • ½ teaspoon Dijon mustard
  • ¼ teaspoon sea salt
  • 1 cup light-tasting avocado oil

Optional additions include garlic powder, smoked paprika, or a pinch of cayenne for extra flavor. Using room-temperature ingredients is key to achieving a smooth, thick texture.

How to Make Keto Avocado Oil Mayo

To make this DIY mayonnaise with avocado oil, start by adding the egg, lemon juice, mustard, and salt to a wide-mouth jar. Pour the avocado oil on top.

Place an immersion blender at the bottom of the jar and blend without moving it for about 20 seconds. Once the mixture starts to thicken at the bottom, slowly lift the blender to incorporate the remaining oil. In under a minute, your keto-friendly mayonnaise recipe is ready.

Tips for Perfect Keto-Friendly Mayonnaise

Using a light avocado oil ensures a neutral flavor, while extra virgin olive oil may taste bitter. Always start blending from the bottom and avoid moving the blender too quickly.

If your mayo doesn’t thicken, the ingredients may be too cold. Let them come to room temperature and try again. For a creative twist, this mayo can even be seasoned and used alongside vegetables like Garlic Butter Corn with Melty Cheese.

Is Mayonnaise Keto Friendly?

Yes, mayonnaise can absolutely be keto friendly when made correctly. Store-bought versions often contain sugar and refined oils that don’t align with a keto lifestyle.

This homemade keto mayonnaise recipe uses avocado oil, which provides healthy fats and zero carbs. It’s also an excellent base for meals like Protein-Packed Cottage Cheese Egg Bake.

Ways to Use Keto Avocado Oil Mayo

This easy avocado oil mayo works in countless recipes. Use it as a spread for burgers, mix it into chicken or tuna salad, or serve it as a dip for veggies.

It’s especially delicious with sides like Cheesy Mashed Potato Puffs or tossed into fresh salads for added creaminess.

Flavor Variations for Homemade Mayo Keto Style

You can easily customize this homemade mayonnaise keto recipe. Add roasted garlic for a mild aioli, chipotle powder for smoky heat, or fresh herbs like dill or parsley.

These variations pair wonderfully with light dishes such as Cucumber Dill Salad or roasted vegetables.

How to Store Homemade Keto Mayo

Store your keto avocado oil mayo in an airtight container in the refrigerator for up to one week. Because it contains raw egg, always keep it chilled.

For added safety, you can use pasteurized eggs. If you enjoy make-ahead meals, you may also like Freezer Breakfast Sandwiches for easy weekly prep.

Frequently Asked Questions About Keto Mayo

Can I use olive oil instead of avocado oil?
Yes, but olive oil has a stronger flavor that may overpower the mayo.

Why didn’t my mayo thicken?
Cold ingredients or lifting the blender too early are the most common reasons.

Can I make this without an immersion blender?
Yes, a food processor works, but an immersion blender is faster and more reliable.

Is this Whole30 or Paleo friendly?
Yes, as long as compliant mustard and vinegar are used.
