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 submerged. Season lightly with salt. Bring to a boil, then reduce to a simmer.
03 - Cook uncovered for 9-12 minutes, stirring frequently to prevent sticking. Continue until pasta reaches al dente texture and most liquid has been absorbed, creating a naturally thickened sauce.
04 - Reduce heat to low. Stir in grated Parmesan, lemon zest and juice if using, and chopped parsley. Toss until sauce evenly coats pasta and becomes creamy. Adjust seasoning with salt and pepper to taste.
05 - Serve immediately while hot. Garnish with additional fresh parsley and extra Parmesan cheese if desired. Enjoy the silky, garlicky pasta while it's at its best texture and temperature.
