❤️ Why you’ll love it

This immersion blender mayo is so finger-licking good, you’ll want to spread it on everything! Make your own deliciously creamy mayo in about two minutes; your family won’t even know it’s keto! 

Is mayonnaise keto-friendly?

It can be. Regular mayo and salad dressings sometimes contain sugar and other additives that are not allowed on the ketogenic diet, so I prefer to make my own mayonnaise. Always check the label carefully if you pick one up from the grocery store.

Better yet, you can make your own with this homemade recipe made with no added sugar and only keto-friendly ingredients. With only five ingredients, you can whip up a delightfully tastier and healthier version. Read on to learn how to make the best keto mayo out there!

All you need to make this easy recipe are an immersion blender and a mason jar. I prefer just to whisk the simple ingredients in a mason jar and store it in the same container for easy clean up.

If you don’t have an immersion blender, a hand mixer will work just fine. Of course, you can also use a regular blender if you prefer, but it might be a challenge to scrape out a small amount of mayo out of a large blender.  

🧾 Ingredients Used

acv, dijon mustard, eggs for keto mayo recipe.
  • Olive oil: Use your choice of oil, ideally olive oil or avocado oil. Avoid inflammatory vegetable oils like soybean oil or canola oil.
  • Whole egg: This will help bind the ingredients together. If you’re scared of the risk of salmonella, you can use pasteurized eggs instead.
  • Dijon mustard: I prefer Dijon mustard, but you can use yellow mustard instead. Mustard also helps bind and stabilize the ingredients in this low carb mayonnaise.
  • Apple cider vinegar: You can use white vinegar if that’s what you have on hand.
  • Salt: To taste.

🔪 How To Make This Recipe

  1. Add the apple cider vinegar, egg, Dijon mustard, and salt to a mason jar. Pour in the olive oil last.
  2. Put the immersion blender into the bottom of the mason jar, and then turn it on.
  3. Keep it still and let it start to blend the entire mixture from the bottom of the jar. 
  4. Once it starts to thicken, move the immersion blender upwards as it blends the mix.
  5. Blend for 20 – 30 seconds till it is thoroughly mixed in a creamy consistency.

🥫 Storing and Reheating

You can store your homemade keto mayo recipe in an airtight container in the refrigerator for about a week at most. You should use it all up within that time for best results. I recommend that you do not freeze the mayonnaise. If you do, it would curdle and separate. 

💭 Tips and Variations

  • Make sure the egg and other ingredients are at room temperature. This is important so that the mayo doesn’t split up. Room temperature will also help it thicken properly.
  • Use a mason jar or airtight container with a wide mouth so it’ll be easy for you to scoop the mayo out.
  • You can skip the egg for a vegan option.
  • If you need something sweeter for your salad dressing, try this homemade sweet mayo dressing.
  • Add some lime juice or lemon juice for a little bit of zesty flavor.
  • For a spicy version, try this spicy mayo recipe.
  • Jazz it up with different spices and flavorings for an exciting treat. Add some garlic powder, black pepper, or herbs to switch things up. Have fun with it!

👩‍🍳 Frequently asked questions

Is homemade mayonnaise healthy?

Homemade mayonnaise is quite healthy, especially if you’re on a low carb or keto diet. The healthy fats in it are much needed, and it contains little to no carbs at all! The best part is that you can be sure there are no hidden additives to the keto mayonnaise because it’s homemade. So go ahead and indulge in it. You know you want to.

Is it safe to eat mayonnaise?

Mayonnaise is safe to eat. Sometimes, there is the fear of salmonella in eating raw eggs, but the risk is the same if you eat your eggs runny. However, the acidity in the vinegar kinda neutralizes harmful bacteria, so the risk is really very tiny. To be absolutely safe, though, you can use pasteurized eggs for this keto mayonnaise recipe.

Can you eat mayonnaise on keto?

Yes! Mayo can be a great source of healthy fats for your keto lifestyle, especially in this easy keto mayonnaise. Be cautious with storebought mayo as it is often made with unhealthy oils, added sugar, and preservation. Primal Kitchen is your best choice for storebought mayo, but it’s easy enough to make it yourself!
