Notes
Storage:
For the Fridge: If you've got leftovers (lucky you!), store them in an airtight container in the fridge. They'll keep for up to 5 days. Just bring to room temperature before you're ready to enjoy.
For the Freezer: As a general rule, steer clear from freezing pasta, but you can freeze just the pesto in an airtight container for up to 3 months. Defrost in the fridge and stir into freshly cooked pasta when you're ready to serve. Warning, the color might not be as vibrant, but it'll taste just as good.
Tips:
Nuts: Pine nuts are the classic ingredient, but toasted almonds, walnuts, and even nutty pepitas are delicious.
Herbs & Greens: Basil is the work horse of pesto. It's floral and bright and a fan-favorite. Try adding in other herbs and greens, too - peppery arugula adds a nice, slightly spicy kick: we love this Arugula and Basil Pesto recipe. And herbs like cilantro and parsley add a bright depth of flavor - pepitas and walnuts would pair nicely with these. You can even make a version with fresh spinach for extra color and brightness.
Cheeses: Hard, sharp, nutty cheeses work best in pestos. Parmesan is always a winner, but also give pecorino romano a try- it's slightly tangy and absolutely delicious.
Citrus & Spice: Adding in a bit of citrus zest brightens up any pesto. We love the essence of lemon zest, especially. And if you're a spice lover, don't be afraid to add in a pinch of red pepper flakes for an extra kick.
