In the work bowl of a food processor, pulse together basil, walnuts, Parmesan, garlic, and lemon juice until finely chopped and well combined. With processor running, add oil in a slow, steady stream until incorporated. Add salt and pepper to taste. Pesto may be kept in an airtight container in the refrigerator for up to 1 week or frozen for up to 2 months.
