Melt the butter in a large skillet over medium heat. Add the garlic and saute until fragrant, about 30 seconds
Stir in the cream and lemon juice. Bring to a simmer and cook for 5 minutes until the sauce is thick enough to coat the back of a spoon.
Remove from the heat and stir in the grated Parmesan cheese. Season with salt and freshly cracked black pepper to taste.
