Are you a sucker for condiments? I love a good sauce or spread and this Basil Pesto Aioli, sometimes called Pesto Mayo, is moving to the top of my list pretty fast.
Pesto aioli is the perfect condiment for so many different foods. With fresh flavors of basil and garlic, slather it on sandwiches, paninis or just use it to dip French fries.
Most people think that pesto aioli is as simple as mixing basil pesto with mayonnaise and essentially, that would make sense.
Ingredients for pesto are typically fresh basil, pine nuts, seasoning and olive oil. Mayonnaise made from eggs, oil and salt. But you can even make this version with a spinach pesto or sundried tomato pesto.
Actually, aioli and flavored mayonnaise are a little different, but for quick and easy aioli sauces, using mayo as a base is acceptable. At least in my world…
PRO TIP: Use fresh garlic opposed to pre minced jarred garlic. Jarred garlic is sweet while fresh will be more garlicky.
But if you simply mix the two together, the olive from pesto will not emulsify correctly with the mayonnaise making a sloppy mess with an oil slick on top.
Instead, you want to start with a basic garlic aioli, just mayo and fresh garlic, and then add the other ingredients that make pesto, well, pesto. That means basil!
I also used pine nuts, but these can be easily omitted should someone in you family be allergic to nuts. Or they are just to darn expensive (pine nuts are $$$$).
Lemon juice is also an element that gives this aioli sauce a small acidic kick. It, too, can be omitted. Fresh lemon juice is always more vibrant and bright than bottled, but again, bottled will do.
I like to make mine in a small food processor just because it is easy, but you can also finely chop all the ingredients and fold them together.

Commonly asked questions about how to make basil aioli sauce:
Why do you use jarred mayo?
Don’t assume I meant I was using jarred! I actually make my own mayonnaise. But you can easily buy a GOOD jarred mayo and use that too to save time.
Can I use dried basil?
This is one recipe where fresh basil is really a key element, so I am going to say no. Dried basil doesn’t have the same aromatics or oils to give the mayo enough flavor.
