01 - Heat olive oil and butter in a large pot or deep skillet over medium heat. Add minced garlic and sauté for 1-2 minutes until fragrant but not browned, being careful not to burn the garlic.
02 - Add uncooked pasta directly to the pot. Pour in vegetable broth or water, ensuring pasta is just covered. Season lightly with salt to enhance flavor absorption during cooking.
03 - Bring to a boil, then reduce to a simmer. Stir frequently to prevent sticking and cook uncovered for 9-12 minutes until pasta is al dente and most liquid has been absorbed, creating a starchy base for the sauce.
04 - Reduce heat to low. Stir in grated Parmesan, lemon zest and juice if using, and chopped parsley. Toss until sauce coats pasta and becomes creamy. Adjust seasoning with salt and pepper to taste.
05 - Serve immediately while hot, garnished with additional parsley and Parmesan if desired. The dish is best enjoyed fresh from the stove.
