The Keto Case for Mayonnaise
Mayonnaise is built on a foundation of fat, which is the cornerstone of the ketogenic diet. A traditional mayonnaise recipe consists of oil, egg yolks, and an acidic agent like vinegar or lemon juice. This macronutrient profile—high fat and very low carb—is what makes it an attractive condiment for keto dieters seeking to add flavor and richness to their meals without spiking insulin levels. A single serving can provide a significant amount of healthy fats, contributing to the daily intake required to maintain ketosis. This creamy base makes it perfect for a wide variety of keto dishes, from dressings to savory dips.
Navigating the Store-Bought Mayonnaise Maze
While basic mayonnaise is keto-friendly, a significant percentage of commercial products are not ideal for a clean ketogenic diet. Here’s what to look for and what to avoid.
The Problem with Unhealthy Oils and Additives
Many mass-produced mayonnaise brands rely on cheap, highly processed vegetable oils such as soybean, canola, corn, and regular sunflower oil. These oils contain high levels of omega-6 fatty acids, which can contribute to inflammation when consumed in excess. Furthermore, many brands include hidden sugars and high-fructose corn syrup to enhance flavor and artificial preservatives to extend shelf life. It is also crucial to avoid products labeled as "light," "reduced-fat," or "fat-free," as these typically contain higher carbohydrate loads and starches to replace the fat.
What to Look for in a Keto-Friendly Brand
For the healthiest store-bought option, prioritize brands that use clean, anti-inflammatory oils. Look for the following:
- Avocado Oil: A favorite among keto enthusiasts for its neutral flavor and high content of monounsaturated fats.
- Olive Oil: Opt for light or extra light olive oil, as extra virgin varieties can have a stronger, more bitter flavor.
- MCT Oil: Some specialty keto mayos incorporate MCT oil to provide a quick source of energy.
- No Added Sugar: The ingredient list should be free of any type of sugar or corn syrup.
- Minimal Ingredients: The fewer ingredients listed, the better. Look for a simple recipe containing just eggs, oil, and vinegar/lemon juice.
The Ultimate Option: Homemade Keto Mayonnaise
For complete control over the ingredients and quality, making your own mayonnaise at home is the best approach. It is surprisingly simple and takes only a few minutes.
Simple Homemade Mayonnaise Recipe
Ingredients:
- 1 large egg (at room temperature)
- 1 cup avocado or light olive oil
- 1 tsp Dijon mustard
- 1 tbsp lemon juice or apple cider vinegar
- Pinch of salt
Instructions:
- Combine the egg, mustard, acid, and salt in a tall, narrow jar or a container that fits your immersion blender snugly.
- Place the immersion blender at the bottom of the jar and turn it on, keeping it still for about 10-15 seconds until you see the mixture emulsify and thicken.
- Slowly tilt and move the blender up through the mixture to incorporate all the oil, continuing until a thick, creamy consistency is achieved.
- Taste and adjust seasoning as needed.

Conclusion: Choose Wisely to Enjoy Mayonnaise on Keto
The question, "Can you use mayonnaise in keto?" is met with a resounding "yes," but with a crucial caveat: ingredient quality is paramount. While the basic composition of mayo aligns perfectly with a low-carb, high-fat diet, the prevalence of unhealthy additives and processed oils in many store-bought jars means dieters must be vigilant. By carefully reading labels to select high-quality brands using avocado or olive oil, or by simply making your own, you can confidently enjoy the rich, creamy flavor of mayonnaise while staying in ketosis. The effort to find or create the right mayo will pay off in improved health benefits and more delicious, satisfying meals.
