Lemon Mayo Recipe: Zesty Creamy Spread for Sandwiches

I’ve perfected this creamy lemon mayo to elevate sandwiches, dips, and dressings with minimal effort. The balance of bright citrus and rich mayo creates a versatile spread that outshines store-bought versions every time.

This recipe relies on just a few ingredients—egg yolks, oil, fresh lemon juice, and a touch of seasoning. The key is slowly emulsifying the oil into the yolks for a smooth, stable texture that won’t separate.

What you’ll get is a tangy, velvety condiment that clings to bread, veggies, or seafood. It’s thick enough to spread but light enough to drizzle, with just the right zing from the lemon.

Make a batch and keep it on hand for sandwiches, burgers, or as a dip for fries. The flavor only improves after a few hours in the fridge.

Ingredients for Lemon Mayo

Seven ingredients transform into this velvety citrus spread with minimal effort required.

The oil choice matters here. Avocado oil is my go-to for its neutral flavor and high smoke point, but any light oil works—just avoid strongly flavored extra-virgin olive oil (it overpowers the lemon). Room temperature egg yolks emulsify better than cold ones, so pull them out 30 minutes before starting. If you’re doubling the batch, use a food processor for effortless mixing.

No Dijon? Yellow mustard at half the amount works in a pinch, but the flavor will be milder. Short on fresh lemon juice? Bottled works (just use a bit more for the same zing). Want it thicker? Reduce the oil slightly. Prefer a smoother texture? Strain the finished mayo through a fine-mesh sieve to remove any stray bits.

This keeps 5-7 days in the fridge in an airtight jar. The lemon oil may separate slightly—just give it a stir before using. For longer storage, freeze in ice cube trays for up to 3 months (thaw in the fridge overnight).

Step-by-Step Instructions for Lemon Mayo

This method ensures a smooth, stable emulsion with bright citrus flavor.

Step 1: Whisk Egg Yolks with Acidic Components

Place the 2 whole Egg Yolks in a medium bowl. I always use room temperature yolks because cold ones can cause the emulsion to break later. Whisk them vigorously for 30 seconds until they turn pale yellow and slightly thickened.

Add the 3 tbsp Fresh Lemon Juice and 1 tsp Dijon Mustard, then whisk for another 30 seconds until fully combined. The mustard acts as an emulsifier while the lemon juice provides the signature tang. You’ll notice the mixture lighten slightly as air incorporates.

Step 2: Begin Slow Oil Incorporation

With one hand, continue whisking the egg mixture while very slowly drizzling in the 1.5 cups Neutral Oil with the other. Start with just a few drops at a time – this is critical for creating a stable base. After about ¼ cup of oil has been incorporated, you can increase to a thin stream.

The mixture will begin to thicken and turn opaque as the oil emulsifies. If it starts looking separated, stop adding oil and whisk vigorously for 10-15 seconds to bring it back together. This step requires patience but ensures a creamy texture.

Step 3: Complete Emulsion with Remaining Oil

Once about half the oil is incorporated, you can add the remaining oil in a slightly faster but still controlled stream. Continue whisking constantly – don’t stop until all the oil is in. The mixture should now be thick and glossy, coating the back of a spoon.

Watch for the color to turn a pale, creamy white. This visual change confirms the emulsion is forming properly. The entire oil incorporation process should take about 3-4 minutes of continuous whisking.

Step 4: Season and Adjust Consistency

Add the 0.5 tsp Salt, 0.25 tsp White Pepper, and 0.25 tsp Garlic Powder to the mayonnaise. Fold these in gently with a spatula to avoid breaking the emulsion. Taste and adjust seasoning if needed, though I find these proportions perfect for most palates.

The final product should be thick but still pourable. If it’s too thick, whisk in 1 teaspoon of warm water to loosen. If too thin, whisk in another 1 tablespoon of oil. Transfer to a clean jar and refrigerate for at least 30 minutes before using to allow flavors to meld.

Dietary Considerations for This Recipe

Gluten-Free Friendly

This spread is naturally gluten-free, making it perfect for anyone with sensitivities. All the ingredients—egg yolks, oil, lemon juice, and seasonings—are inherently free of gluten. I always double-check my Dijon mustard label, as some brands add thickeners.

Dairy-Free Option

Despite its creamy texture, this mayo contains no dairy. The richness comes from egg yolks and oil, not butter or cream. That said, if you’re allergic to eggs, this recipe won’t work for you—commercial vegan mayos would be your best alternative.

Low-Carb & Keto

With only 2g net carbs per 2-tbsp serving, this fits perfectly into low-carb and keto diets. The lemon juice contributes minimal carbs, while the oil and eggs provide healthy fats. I love that it adds flavor without derailing my macros. 💪

Egg Allergy Note

Since raw egg yolks are the base, this isn’t suitable for those with egg allergies. For a safe alternative, look for commercial egg-free mayonnaises and mix in 3 tbsp fresh lemon juice and 1 tsp Dijon to mimic the flavor.

Vegan Adaptation

To make this vegan, replace the egg yolks with 3 tbsp aquafaba (chickpea brine) and proceed with the same method. The texture might be slightly thinner, but the lemon flavor shines just as bright. I tested this in my tiny Boston kitchen with great results.

Sodium Considerations

The recipe contains 0.5 tsp salt, which you can reduce or omit entirely. For a lower-sodium version, use ¼ tsp salt and boost flavor with extra lemon juice or a pinch of garlic powder.
