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.
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.

Ingredient Swaps
- Olive Oil—if you don’t love the flavor of olive oil, simply omit and use all canola oil.

👩🍳Step-By-Step Instructions
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, process in more canola oil by the teaspoon until your desired thickness is achieved.
🙋♀️Recipe FAQ
In addition to smoothness, oil binds together and emulsifies with the egg to create the classic creamy texture we know and love.
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.
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 immediately.
