Add one cup of mayonnaise and one cup of basil to a food processor and pulse until fully combined, typically 45-60 seconds.
Then, add three cloves of garlic (ideally chopped or run through a garlic press) and then pulse again until well combined, typically 30-45 seconds.
Finally, add 1 tablespoon of lemon juice and 1 teaspoon of fresh lemon zest and pulse until well combined, typically 30 seconds.
Serve with all your favorite sandwiches and wraps!
Notes
Mayonnaise and aioli are slightly different in that the former uses eggs and canola oil, the latter uses garlic and olive oil. However, if you use vegan mayonnaise, it becomes quite easy to transform this into an aioli.
You can totally use other herbs than basil - for instance, I've tried this with cilantro, parsley and oregano to name a few. You do have to use fresh herbs though!
