Homemade Mayonnaise
Mayonnaise is a staple keto condiments recipe that is perfect for the keto diet. Homemade keto mayo is so much better than store bought mayo. I love that I know exactly what has gone into it when I make my own healthy mayonnaise.
Most mayonnaise recipes are naturally low in carbs as they should basically contain eggs, oil and acid (in the form of vinegar or lemon juice).
Sadly, and I have no idea why sweetener gets added to some, but in my opinion, it totally does not need it.
Making easy, no sugar mayonnaise is just that, easy! It is cheap and tastes so much better. Plus, you can use it for low carb sauce recipes and keto dressings. You can make our amazing Keto Ranch Dressing, Keto Blue Cheese Dressing and so many more delicious low carb recipes with our keto mayo.
Read on for some extra tips to have a no-fail mayonnaise every time. I have even added a how to make mayonnaise in your Thermomix for our thermal cooking lovers too.
Why You’ll Love This Recipe
No sugar! Mayonnaise that is commercially produced usually has sugar added to it, along with lots of other additives; and you don’t need any of that!
Quick and easy – this recipe takes hardly any time to make, so you can make fresh keto mayonnaise with whatever flavour variation you choose.
Keeps for a few days – it is safe to store keto mayonnaise in an airtight container in the fridge for 5-7 days.
Variations – make Whole30 mayonnaise, paleo, and keto-friendly mayonnaise with just a few ingredients.
The Ingredients
Scroll to the recipe card at the bottom for the quantity of ingredients used and the full detailed method to make homemade keto mayonnaise!
There are just 4 main ingredients in this easy keto mayo recipe.
Oil: I use neutral-tasting olive oil, avocado oil or fractionated coconut oil. Neutral taste olive oil is NOT extra virgin olive oil. Please use light olive oil or neutral oil.
You can make avocado oil mayo but check the avocado oil first. Some are quite robust in flavour so look for a mild-tasting one. Fractionated coconut oil is liquid coconut oil or MCT oil. This is perfect for bulletproof mayonnaise.
Eggs: I use fresh free-range room temperature egg yolks. The eggs are not cooked in this recipe. If you have concerns over salmonella then please use pasteurised eggs or whisk the mayonnaise over a gentle heat for a cooked mayonnaise.
Apple cider vinegar or lemon juice: the acid in vinegar or lemon juice is what helps to emulsify the mayo.
How To Make Keto Mayonnaise
Step 1: Mix the room temperature egg yolk, vinegar/lemon juice and mustard together. You can do this with a whisk, food processor, blender, or with a stick blender in a suitable container.
Step 2: While whisking or blending, slowly drizzle the oil in a thin stream until the mayonnaise emulsifies.
Hot Tips & FAQs
Oil choice is very important in making mayonnaise. You want to choose oils that are not strong in flavour. The light olive oil is not the same as virgin or extra virgin. It has more of a neutral flavour and won’t dominate the mayonnaise. Extra virgin olive oil is not recommended.
Whether making mayonnaise with a whisk, stick blender or Thermomix® the trick is to add the oil in a slow steady stream to slowly emulsify the mayonnaise. If you add it too fast, it doesn’t come together properly. As you are whisking or blending the egg mix, the slow stream of oil will slowly help to form a thick delicious consistency.
I love the addition of Dijon mustard (or any mild mustard) and a good seasoning to my recipe.
A few other low carb mayonnaise variations: Chipotle mayonnaise recipes are pretty popular at the moment and the chipotles in adobo can be found in most supermarkets these days. A keto garlic aioli is also a pretty great recipe to have on hand. You can also use roasted garlic or black garlic for some more interesting flavours.
How to Fix a Broken Mayonnaise
I have 3 tips to fix mayonnaise that is broken or is too thin.
- Whisk in two teaspoons of boiling water. This will help the yolks to re-emulsify with the oil, bringing the mayo back together. If it still is not thick add 1-2 more teaspoons to thicken.
- Whisk in 1 teaspoon of extra mustard to the broken mayonnaise until it emulsifies and thickens.
- Add another egg yolk and whisk (or process) until thick.
Mayonnaise Thermomix
It is super simple to make mayonnaise in the Thermomix. The additional benefit is if you would prefer a cooked mayonnaise too. I have included a method to make our easy keto mayonnaise in the thermie. If you would prefer to cook your mayonnaise; add the eggs, mustard and vinegar/juice; set the mixer to 4 min/37°C/speed 4. In the last minute or so begin to pour the oil and mix until thick and emulsified.

Help! I just made this using avocado oil and it has a really strong oily taste. It is also yellow not white . How can I fix it . The oil was expensive so I don’t want to chuck it out . I made it using the Thermomix method
-
Avocado oil is of course going to affect the colour of the mayonnaise. As for the flavour is your avocado oil a “mild taste” one. It should state it on the label. Any oils used for mayonnaise should always be a mild taste or neutral oil as specified in the recipe. In saying that avocado oil mayonnaise will definitely be more robust in flavour than a light tasting oil. To make it less “oily” in flavour you can add more acid or combine it with some sour cream to dilute as you use it.
