In a skillet over medium heat, melt 1 tablespoon of butter. Add the shrimp, salt, and pepper. Cook for 2-3 minutes on each side until the shrimp are pink and opaque.

Remove the shrimp from the skillet and set aside. In the same skillet, add the remaining tablespoon of butter and minced garlic. Sauté for 1-2 minutes until fragrant.

Stir in the lemon juice and red pepper flakes, then return the shrimp to the skillet. Toss to coat in the sauce and heat through for another minute.

Garnish with chopped parsley and serve immediately.
