Pesto mayo is one of my all-time favorite recipes! I usually try to make a batch of homemade basil pesto beforehand, but if I don’t have the time or ingredients, store-bought pesto works too.

You really do need an immersion blender for this recipe. I’ve tried to make it in a blender and it just doesn’t work as well, or as quickly. The best combination is a handheld immersion blender and a tall narrow jar. A jar that is too wide or too large will not emulsify the ingredients the way a skinny jar will.

I sometimes use pesto mayo as a base for this shredded chicken salad, in wraps, on burgers, as a dip, and to make the best summertime potato salad! It’s super creamy with a light-yet-distinct basil flavor. My family loves it and I hope you do too.

📋 Ingredients

Ingredients to make pesto mayo.

Ingredient Notes

  • Lemon Juice—Fresh lemon juice tastes best but use bottled if that’s what you have.
  • Pesto—You can use homemade or store-bought pesto.

It’s important to note that when making substitutions in recipes, the texture and flavor may be slightly different. However, these substitutes are the best options if you are looking to change the original recipe.

Ingredient Substitutions

  • Olive Oil—If you don’t love the flavor of olive oil, simply omit it and use all canola oil.
  • Pesto—Use any flavor of pesto you like! Roasted red pepper pesto, olive pesto, or this spinach pesto with arugula are especially good.

👩‍🍳 How To make Pesto Mayo

STEP 1—Place the canola oil, olive oil, egg, lemon juice, white vinegar, and salt in a tall, skinny glass jar. I use an 850ml (¾L) Weck jar.

STEP 2—Use a handheld immersion blender to process everything together to a thick mayonnaise-like consistency, about 10 to 15 seconds.

STEP 3—Spoon the mayonnaise into a bowl. Add the pesto and stir gently to combine (you can also do this directly in the jar).

STEP 4—Once mixed, store in a sealed container or jar in the refrigerator for up to one week.

🗣 Expert Tips

1. The ingredient amounts are too small to emulsify in a stand blender.
2. Use a room-temperature egg. It will be more “relaxed” than a cold egg from the fridge.
3. Taste and adjust the salt, lemon juice, or vinegar after blending. I sometimes like a little more salt.

📝 Recipe Notes

  • If your jar is too wide this recipe may not work. The jar should be just large enough to fit the immersion blender inside.
  • If the mayo seems a bit thin after blending, blend in one more teaspoon of canola oil. Repeat until your desired thickness is achieved.

🙋‍♀️ Recipe FAQ

Why is oil used in mayonnaise?

In addition to smoothness, oil binds together and emulsifies with the egg to create the classic creamy texture we know and love.

What does lemon juice do in mayonnaise?

Lemon juice adds acidity to balance the heaviness of the oil and egg. It also helps stabilize the texture of the mayo to prevent it from splitting apart.

How long can homemade mayonnaise be stored in the refrigerator?

I store mine in a clean glass jar for up to one week, however, you can also go by other cues such as smell and look. If you see mold or the mayo smells off, discard it immediately.
