Preheat oven to 400 degrees F. In a small bowl, combine the melted butter, minced garlic, juice of half the lemon and lemon zest.
Spread shrimp on a sheet pan in an even layer. Sprinkle with salt and pepper. Drizzle with lemon butter and toss gently until evenly coated. Bake for 8 to 10 minutes, or until pink and cooked through.
Remove from oven and squeeze remaining lemon half over shrimp.
