This simple Italian sauce brings summery flavor to all sorts of dishes, including our Pesto Pizzas and Chicken Fettuccine with Pesto Cream Sauce. Pesto is traditionally made with cheese, but it's just as good without (it freezes better, too).
When you plan on freezing pesto, cook the basil briefly in salted water before mixing with the other ingredients; this will help preserve its bright color and fresh taste. To freeze, spoon pesto into an ice-cube tray (2 tablespoons per cube); cover with plastic wrap. Freeze overnight, then transfer cubes to a resealable plastic bag; keep up to 6 months. Defrost pesto at room temperature, about 20 minutes (or at 30-second intervals in the microwave). Mash with a fork before using in recipes.
