Rinse 1 pound of shrimp under cold water and pat them dry. Remove shells and devein if necessary. Finely mince 4 cloves of garlic.

Melt 4 tablespoons of unsalted butter in a large skillet over medium heat until bubbling, about 1-2 minutes. Add minced garlic and cook for 1 minute until fragrant.

Add the shrimp in a single layer and cook for 2-3 minutes until pink and opaque. Season with salt, black pepper, and red pepper flakes.

Once cooked through, remove from heat and toss the shrimp in the garlic butter sauce.

Transfer to a serving platter, sprinkle with parsley, and serve with lemon wedges.
