01 - Pat shrimp dry with paper towels and season lightly with salt and pepper.
02 - In a large skillet, melt the butter over medium heat. Add garlic and sauté until fragrant, about 1 minute.
03 - Add shrimp to the skillet in a single layer. Cook for 2 minutes per side, or until pink and opaque. Transfer shrimp to a plate and set aside.
04 - Pour heavy cream into the skillet and bring to a gentle simmer, stirring frequently. Add Parmesan and stir until melted and the sauce is smooth, about 2-3 minutes.
05 - Return shrimp and any juices to the skillet. Stir to coat in the creamy sauce. Add lemon juice and chopped parsley. Adjust seasoning with salt and pepper.
06 - Serve immediately, garnished with extra parsley if desired.
