Cook pasta until al dente. In a skillet, over medium heat, add your butter. Once hot, add your garlic and cook for 2 minutes or until very light golden brown. Then add your lemon juice, lemon zest and heavy cream. Cook until slightly thickened. Season to taste with salt and pepper. Add your cooked pasta and toss until evenly coated. Serve with Parmesan cheese and chopped parsley. Enjoy!
