Prepare the Shrimp: If not already done, peel and devein the shrimp. Rinse under cold water and pat dry with paper towels. Season with salt and freshly ground black pepper.

Melt the Butter: In a large skillet, melt the butter over medium heat. Allow it to become bubbly but not browned.

Sauté the Garlic: Add the minced garlic to the melted butter and sauté for about 1 minute, or until fragrant. Be careful not to burn the garlic.

Cook the Shrimp: Add the seasoned shrimp to the skillet. Cook for 2-3 minutes on one side until they turn pink and opaque. Flip the shrimp and cook for an additional 1-2 minutes until fully cooked through.

Add Flavor: Sprinkle in the red chili flakes, lemon juice, and lemon zest. Stir well to combine and let the flavors meld for about 1 minute.

Finish with Parsley: Remove the skillet from heat and stir in the chopped parsley. Adjust seasoning with additional salt, black pepper, and red chili flakes if desired.

Serve: Transfer the shrimp to a serving platter and garnish with additional parsley. Serve with lemon wedges on the side for extra zest.
