Boil a large pot of salted water and cook the pasta according to package instructions.
In a large skillet, melt the butter over medium heat.
Add minced garlic and sauté until fragrant, about 1 minute.
Pour in the lemon juice and bring to a gentle simmer.
Add the cooked pasta directly to the skillet, reserving some pasta water.
Stir in the lemon zest and heavy cream, mixing well to combine.
If the sauce is too thick, add reserved pasta water until desired consistency is reached.
Season with salt and pepper to taste, and stir in grated Parmesan cheese.
Garnish with fresh parsley before serving.
