The Keto-Friendly Nature of Full-Fat Mayonnaise
At its core, mayonnaise is a simple emulsion of oil, egg yolk, and an acidic ingredient like vinegar or lemon juice. These base ingredients are inherently high in fat and contain virtually no carbohydrates, making traditional, full-fat mayo a natural fit for the ketogenic diet. The high-fat content is beneficial for keto dieters, who rely on healthy fats for energy when carbohydrate intake is restricted. A single tablespoon can provide a significant boost of fat to help meet daily macronutrient goals.
The Hidden Carb Trap: What to Avoid in Store-Bought Mayo
While the basic recipe is keto-approved, many commercial mayonnaise brands add ingredients that compromise their low-carb status. It is essential to read labels carefully to avoid products that could kick you out of ketosis. The main culprits to watch for are added sugars and inflammatory vegetable oils.
Commonly Added Ingredients to Avoid:
- Sugar and High-Fructose Corn Syrup: These are frequently added to enhance flavor and are an immediate red flag for keto dieters.
- Canola and Soybean Oil: Many budget-friendly brands use these highly processed, inflammatory oils as their base, which can have negative health effects.
- Reduced-Fat and Fat-Free Varieties: Removing the fat requires replacement with fillers, often including sugars and starches, making these products non-keto.
- Modified Food Starch: This additive can contribute hidden carbs and is a sign of a highly processed product.
- Sweet-Flavored Mayos: Any flavored mayo, such as honey mustard or sweet chili, will almost certainly contain added sugars.
Choosing the Best Keto-Friendly Mayonnaise
For those who prefer the convenience of store-bought options, there are several brands that cater specifically to the keto market. These products use cleaner, healthier oils and avoid added sugars and preservatives.
Top Store-Bought Keto Mayo Brands:
- Primal Kitchen Avocado Oil Mayo: This brand is certified paleo and keto-friendly, made with avocado oil, organic eggs, and without added sugar.
- Chosen Foods Avocado Oil Mayo: Known for using avocado oil and MCT oil, this mayo is zero-carb and sugar-free.
- Sir Kensington's Avocado Oil Mayo: A good choice for its use of avocado oil and non-GMO ingredients, offering a bright, tangy flavor.
- Duke's Real Mayonnaise: A classic, budget-friendly option that is naturally sugar-free, though some may prefer a healthier oil base.
- Kraft Real Mayo: Another traditional option that can be keto-friendly in its full-fat form, but always check the label for any variations.

How to Make Your Own Keto Mayonnaise
For those who want complete control over their ingredients, making homemade keto mayonnaise is a simple process. The key to success is to use an immersion blender and to add the oil slowly to ensure a proper emulsification.
Simple Immersion Blender Keto Mayo Recipe:
- Ingredients: 1 large, room-temperature egg, 1 tbsp lemon juice or vinegar, 1 tsp Dijon mustard, 1 cup of avocado oil (or a light-tasting olive oil), and salt to taste.
- Instructions: Combine the egg, lemon juice, mustard, and salt in a tall, narrow jar. Pour the oil directly on top.
- Blend: Place the immersion blender head at the bottom of the jar and turn it on high. Do not move it until you see a thick, creamy mayo form at the bottom.
- Emulsify: Slowly begin to tilt and lift the blender head, continuing to blend until all the oil is incorporated and the mixture is thick.
- Store: Keep your fresh, homemade mayo in an airtight container in the refrigerator for up to one week.
Delicious Ways to Use Mayonnaise on a Keto Diet
Mayonnaise is one of the most versatile keto condiments and can be used in a variety of recipes to add flavor and fat content.
- Creamy Salad Dressings: Use it as a base for keto ranch, blue cheese, or thousand island dressings.
- Protein Salads: Create classic tuna, chicken, or egg salad by mixing cooked protein with mayo, chopped celery, and seasonings.
- High-Fat Dips: Serve it as a dip for low-carb vegetables like celery, bell peppers, or cucumber slices.
- Deviled Eggs: A perfect keto appetizer, deviled eggs use mayo to create a rich and creamy filling.
- Binder for Casseroles: Use it in casseroles to provide a creamy texture without adding carbs, like in a creamy broccoli bake.
