This classic Italian pasta dish is incredibly simple yet bursting with flavor. Cook spaghetti until al dente, then sauté minced garlic in olive oil until fragrant. Toss the cooked pasta in the garlic-infused oil, adding red pepper flakes for a spicy kick. Finish with a sprinkle of grated Parmesan cheese and chopped parsley. Serve hot and enjoy the perfect balance of garlic, heat, and cheese.
