For an extra layer of flavor, consider adding a pinch of red pepper flakes to the garlic oil while sautéing. If you don't have time to roast your own red peppers, jarred roasted red peppers can be used as a convenient substitute. Be sure to drain them well before adding them to the dish. Pecorino Romano cheese provides a salty and sharp counterpoint to the other ingredients. Parmesan cheese can be substituted in a pinch. The key to a perfect pasta dish is to ensure the pasta is cooked al dente. Overcooked pasta will become mushy and lose its texture. Don't be afraid to adjust the amount of garlic to your personal preference. Some people love a strong garlic flavor, while others prefer a more subtle taste.
