  2. Step 2: Blend 2 cups packed fresh basil, 1 clove minced garlic, 1/4 cup toasted pine nuts, and 3 tbsp freshly grated pecorino in a food processor until finely chopped, then slowly drizzle in 1/2 cup extra-virgin olive oil while processing until smooth.
  3. Step 3: Cook 8 oz spaghetti in salted boiling water for 8 minutes until al dente. Reserve 1/4 cup pasta water, then toss drained spaghetti with 3/4 cup pesto and 1/4 cup reserved pasta water until glossy and fully coated.
