Preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper.
In a large bowl, combine the shrimp, melted butter, minced garlic, 1 tablespoon chopped parsley, and salt and pepper; toss until the shrimp are evenly coated.
In a small bowl, mix the Italian bread crumbs and grated Parmesan.
Sprinkle the breadcrumb mixture over the shrimp and toss gently to coat, then arrange the shrimp in a single layer on the prepared baking sheet.
Bake for about 7 minutes until the shrimp are opaque and cooked through.
Switch the oven to broil and broil for 1–2 minutes, watching closely, until the top is golden and crisp.
Remove from the oven and garnish with chopped fresh parsley before serving.
