While the pasta cooks, make the pesto. Add the basil, pine nuts, Parmesan cheese, garlic, lemon juice, and kosher salt to a food processor. Pulse until all the ingredients are finely chopped. Add in olive oil and pulse a few more times to combine.
3 cups fresh basil, ¼ cup pine nuts, ½ cup parmesan cheese, ½ cup extra virgin olive oil, 2 cloves garlic, 1 tablespoon lemon juice, 1 teaspoon kosher salt
