Melt butter in a large skillet over medium heat. Add garlic and sauté 1-2 minutes until fragrant.
Place shrimp in the skillet and season with salt, black pepper, and red pepper flakes (if desired). Cook shrimp 2-3 minutes per side until pink.
Pour in chicken broth and lemon juice, letting the mixture simmer 2-3 minutes.
Sprinkle Parmesan cheese, stirring until it melts. Remove from heat and stir in parsley.
Transfer to a serving dish, garnish with lemon wedges, and enjoy immediately.
