Ingredients for Keto Mayo Recipe Immersion Blender
Eight ingredients transform into professional-quality keto mayo with your immersion blender.
| Ingredient | Amount | Notes |
|---|---|---|
| Avocado Oil 🫒 | 1 cup | Neutral-flavored, light refined |
| Large Egg 🥚 | 1 whole | Room temperature, pasteurized preferred |
| Dijon Mustard 🟡 | 1 tsp | Sugar-free variety essential |
| White Vinegar 💧 | 1 tbsp | Or apple cider vinegar |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed preferred |
| Sea Salt 🧂 | ½ tsp | Fine grain, adjust to taste |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground for best flavor |
| Garlic Powder 🧄 | ¼ tsp | Optional for depth of flavor |
The oil choice is critical for a neutral base—avocado oil is ideal due to its high smoke point and mild flavor. Primal Kitchen and Chosen Foods offer excellent refined options. Room temperature eggs are non-negotiable for proper emulsification. Pasteurized eggs are recommended for safety, especially if using raw in other applications. The mustard acts as your emulsifier, so sugar-free Dijon is mandatory to maintain keto compliance.
No avocado oil? Light olive oil works in a pinch (avoid extra-virgin as its flavor is too strong). Out of Dijon? Yellow mustard at equal amount but check the label for added sugars. For vinegar, apple cider or rice vinegar both work well. If you prefer a tangier mayo, increase the lemon juice by half the amount. The garlic powder is optional but adds subtle depth without overpowering.
This keeps 1 week in the fridge in an airtight container. For longer storage, freeze in ice cube trays for up to 3 months. The emulsion may separate slightly after storage—simply re-blend before using. Always use a clean, dry spoon to prevent contamination.

Step-by-Step Instructions for Keto Mayo with Immersion Blender
Master the emulsion technique for a rich, creamy condiment that comes together in under a minute.
Step 1: Combine Acidic Components and Seasonings
In a tall, narrow container suitable for your immersion blender, add the 1 whole Large Egg, 1 tsp Dijon Mustard, 1 tbsp White Vinegar, and 1 tbsp Lemon Juice. The narrow vessel is crucial—it allows the blender to create a strong vortex that pulls the oil into the emulsion.
Next, add the 0.5 tsp Sea Salt, 0.25 tsp Black Pepper, and 0.25 tsp Garlic Powder. I always whisk these dry ingredients into the wet mixture briefly with a fork to distribute them evenly before blending. This prevents pockets of concentrated seasoning in your finished product.
Step 2: Establish the Emulsion Base
Insert the immersion blender and pulse a few times to combine the ingredients. Then, with the blender running continuously at medium speed, begin adding the 1 cup Avocado Oil in a very slow, thin stream. The key here is patience—adding the oil too quickly will break the emulsion.
Watch as the mixture transforms from a pale yellow liquid to a thick, creamy base. This is the emulsion forming. You’ll notice the volume increase significantly as the oil incorporates. The oil should be fully emulsified within 30-40 seconds of blending, depending on your blender’s power.
Step 3: Finish and Adjust Consistency
Once all the oil is incorporated, continue blending for another 10-15 seconds to ensure complete emulsification. The finished product should be thick and glossy, with a pale, creamy color. If it appears too thick, you can thin it slightly with a teaspoon of water, blending briefly to incorporate.
Taste and adjust seasoning if needed. I often find that the flavors meld more intensely after a few minutes, so I recommend letting it sit for 5 minutes before making final adjustments. The garlic powder adds a subtle depth, but feel free to omit it for a more traditional flavor profile.
Step 4: Store and Chill for Optimal Texture
Transfer the mayo to an airtight container. I prefer glass jars for storage as they don’t retain odors and allow you to see the creamy texture. Refrigerate for at least 1 hour before using. This chilling time allows the emulsion to fully set and the flavors to develop.
Your creation will keep in the refrigerator for up to 1 week. The surface may develop a slight separation over time, which is normal—simply stir before using. This method delivers a stable emulsion that won’t break, even when used for dressings or sauces.
Pro Tips For Making Keto Mayo Recipe Immersion Blender
- Use Room Temp Egg: Cold eggs resist emulsifying—let yours sit out for 30 minutes or submerge in warm water for 5. I learned this the hard way after three broken mayos in a row.
- Slow Pour the Oil: Drizzle the avocado oil in a thin, steady stream at first, especially during the first 30 seconds. Sounds tedious, but it’s the only way to guarantee a thick, creamy base.
- Skip the Vinegar Swap: Stick with white vinegar or lemon juice—other acids like apple cider vinegar can overpower the mayo’s mild flavor. My first batch with rice vinegar tasted like salad dressing.
- Pulse, Don’t Blend: Use short pulses with the immersion blender instead of continuous blending. It gives you more control and prevents overheating the mayo, which can cause it to separate.
Troubleshooting This Dish
Broken Emulsion Fix
If your mayo looks thin or separated, don’t panic. Start with 1 tsp of hot water and blend for 10 seconds. The heat helps re-bind the mixture. I’ve saved many batches this way. 💡
Too Thick Texture
When your mayo becomes overly thick, thin it with 1 tsp of water or lemon juice at a time. Blend briefly after each addition until reaching your desired consistency.
Oil Added Too Fast
If you poured the oil too quickly and broke the emulsion, transfer the mixture to a clean container. Add 1 egg yolk and blend again while slowly drizzling in the broken mixture.
Egg Temperature Issues
Cold eggs can prevent proper emulsification. Always use room temperature eggs. If you forget, place the egg in warm water for 5 minutes before starting.
Storage Separation
After refrigeration, you might see slight separation. This is normal. Simply stir vigorously or pulse with your immersion blender for 5 seconds to restore the creamy texture.
Mustard Substitution
If you lack Dijon, use 1 tsp yellow mustard but verify it’s sugar-free. The emulsifiers in mustard are crucial for stability, so never skip this ingredient.
