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.
02 - Add uncooked pasta to the pot. Pour in vegetable broth or water, ensuring pasta is just covered. Season lightly with salt.
03 - Bring to a boil, then reduce to a simmer. Stir frequently to prevent sticking. Cook uncovered for 9-12 minutes until pasta is al dente and most liquid has been absorbed.
04 - Reduce heat to low. Stir in grated Parmesan, lemon zest and juice, and chopped parsley. Toss until sauce coats pasta and becomes creamy. Adjust seasoning with salt and pepper.
05 - Serve immediately, garnished with extra parsley and Parmesan if desired.
