Preheat your oven to 425°F and line a baking sheet with parchment paper or foil.
In a small bowl, combine the melted Garlic Better Butter, lemon juice, lemon zest, salt, black pepper, and red pepper flakes (if desired). Stir well to mix the flavors.
Place the shrimp in a single layer on the prepared baking sheet.
Pour the butter mixture over the shrimp, ensuring that each shrimp is coated evenly.
Place the baking sheet in the preheated oven and bake for about 10-12 minutes, or until the shrimp are pink and cooked through. Be careful not to overcook the shrimp, as they can become rubbery.
Once cooked, remove the sheet pan from the oven and garnish the shrimp with freshly chopped parsley.
Serve the Buttery Sheet Pan Shrimp Scampi hot, with lemon wedges on the side for squeezing over the shrimp. Enjoy as a standalone dish or serve it over pasta, rice, or crusty bread.
