The secret ingredient in the best Homemade Pesto recipe is actually baby spinach. It mellows the bite of the basil just a little bit, so that the flavor of the pesto doesn't overpower other ingredients. Plus, it's nice and bright green!
Place garlic, basil, spinach, cheese, pine nuts, lemon juice, lemon zest, salt, pepper and red pepper flakes in bowl of food processor fitted with knife blade attachment. Pulse until mixture is very finely chopped.
With processor running, slowly drizzle in oil until all oil is incorporated. Makes 1 cup.
