Preheat your oven to 400°F (200°C). Prepare a large baking sheet by greasing it lightly with oil or nonstick spray.

In a medium-sized bowl, combine melted unsalted butter, minced garlic, lemon juice, and Italian seasoning. Whisk until well blended, then season with salt and pepper.

Spread the prepared shrimp in a single layer on the baking sheet for even cooking.

Drizzle the garlic butter mixture over the shrimp and toss gently to cover.

Bake the shrimp in the preheated oven for 8-10 minutes until they turn pink and are firm.

Remove from the oven, let rest for a minute, and sprinkle with chopped parsley before serving.
