Gather your ingredients and ensure they are measured out for a smooth process.
In a mixing bowl, add 1 cup of mayonnaise to form the creamy foundation of your aioli.
Pour in 1 tablespoon of fresh lemon juice and add 1 teaspoon of lemon zest.
Add 1 clove of minced garlic to the mixture.
Sprinkle in salt to taste, mixing well after each addition.
Using a whisk or fork, blend all the ingredients until fully combined and smooth.
Refrigerate the aioli for at least 30 minutes before serving to allow the flavors to meld.
