What Makes This Recipe Special

What sets this Keto Mayonnaise apart from others is the use of avocado oil, which not only gives it a creamy texture but also packs a nutritional punch. Avocado oil is rich in healthy fats, vitamins, and antioxidants, making this mayonnaise not just delicious, but also beneficial for your health. Additionally, using a single pasteurized egg yolk ensures safety while still lending the perfect creaminess to the mix. The subtle tang of Dijon mustard and the brightness of fresh lemon juice elevate the flavors, resulting in a mayonnaise that is far superior to anything you can buy in a jar.

To make your own Keto Mayonnaise, you’ll need the following ingredients:
- 1 large pasteurized egg yolk at room temperature
- 1 teaspoon Dijon mustard
- 1 ¾ teaspoons fresh lemon juice
- 1 cup avocado oil
- 1/8 teaspoon salt plus more to taste
Each ingredient plays a crucial role in achieving the perfect balance of flavor and texture, ensuring that your homemade mayonnaise will be a hit at any meal.
Hardware & Gadgets
Before you get started, make sure you have the following tools on hand:
- Immersion blender or food processor: These are key for emulsifying the oil with the egg yolk.
- Measuring spoons and cups: Precise measurements are important for the best results.
- Mixing bowl: A medium-sized bowl will work well for this recipe.
- Spatula: For scraping down the sides and ensuring all ingredients are well mixed.
Having the right equipment will make the process smoother and more enjoyable, so gather these items before you begin.
Build Keto Mayonnaise Step by Step

Step 1: Gather Ingredients
Start by collecting all your ingredients. Ensure that the egg yolk is at room temperature for optimal emulsification.
Step 2: Combine Egg Yolk and Mustard
In a mixing bowl, add the room temperature egg yolk and Dijon mustard. Whisk them together until well combined.
Step 3: Add Lemon Juice
Next, add the fresh lemon juice to the bowl. This will contribute to the flavor and help stabilize the emulsion.
Step 4: Begin Blending
Using your immersion blender or food processor, start blending the egg mixture on low speed. It’s essential to ensure that all ingredients are well incorporated before adding the oil.
Step 5: Slowly Drizzle in Avocado Oil
With the blender running, very slowly drizzle in the avocado oil. Start with just a few drops and gradually increase the flow as the mixture begins to thicken. This slow addition is crucial for achieving a good emulsion.
Step 6: Season to Taste
Once all the oil has been incorporated and the mayonnaise is thick and creamy, add salt to taste. Feel free to adjust the seasoning as per your preference.
Step 7: Store Properly
Transfer your Keto Mayonnaise to a clean jar or airtight container. It can be stored in the refrigerator for up to a week.
Seasonal Flavor Boosts

Want to jazz up your Keto Mayonnaise? Here are some delightful flavor additions you can try:
- Garlic: Add minced garlic for a delicious garlic aioli.
- Herbs: Fresh dill or basil can give your mayo a refreshing twist.
- Spices: A pinch of smoked paprika or cayenne pepper for a smoky or spicy kick.
- Chipotle: Blend in chipotle peppers for a smoky, spicy flavor that pairs well with many dishes.
These variations can elevate your mayo from simple to sensational, making it a versatile addition to your meals.
Missteps & Fixes
Even the best home cooks can encounter a few bumps in the road. Here are some common missteps and how to fix them:
- If the mayonnaise doesn’t thicken: This often happens if the oil was added too quickly. To fix this, start with a new egg yolk in a clean bowl and slowly add the broken mayonnaise while blending.
- If it tastes too acidic: If you find your mayo too tangy, try adding a pinch of sugar or honey to balance the acidity.
- If it’s too salty: Add a little more avocado oil to dilute the saltiness.
- If it separates: This can happen if the emulsion breaks. Again, start with a fresh yolk and slowly whisk in the separated mayonnaise.
Don’t be discouraged if things don’t go perfectly the first time. With practice, you’ll master the art of making Keto Mayonnaise!
Refrigerate, Freeze, Reheat
To keep your Keto Mayonnaise fresh and flavorful, consider the following storage tips:
Your homemade Keto Mayonnaise can be refrigerated in an airtight container for up to one week. Be sure to keep it chilled and use clean utensils to avoid contamination. However, freezing mayonnaise is not recommended, as it can change the texture when thawed.
If you find that your mayo has thickened too much after refrigeration, simply stir in a small amount of water or lemon juice to loosen it up before serving.
