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, and 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 the pasta and becomes creamy. Adjust seasoning with salt and pepper.
05 - Serve immediately, garnished with extra parsley and Parmesan if desired.
