Preheat the Oven: Preheat your oven to 400°F (200°C) to ensure the shrimp roast quickly and evenly.
Prepare the Shrimp: In a bowl, combine the peeled and deveined shrimp with olive oil, minced garlic, oregano, parsley, salt, and pepper. Toss the shrimp well to coat them evenly in the seasoning mixture.
Coat with Parmesan and Breadcrumbs: Add the grated parmesan cheese and breadcrumbs (if using) to the shrimp. Toss gently to ensure each shrimp is coated with the parmesan and breadcrumbs, creating a cheesy crust.
Arrange the Shrimp: Line a baking sheet with parchment paper or lightly grease it with oil. Arrange the shrimp in a single layer on the baking sheet, ensuring they are not overlapping for even cooking.
Roast the Shrimp: Roast the shrimp in the preheated oven for 8-10 minutes, or until they turn pink and opaque, and the parmesan has formed a crispy, golden layer.
Serve and Garnish: Once the shrimp are roasted, remove them from the oven and transfer to a serving platter. Garnish with freshly chopped parsley and a squeeze of lemon juice for a fresh, zesty touch. Serve with lemon wedges on the side for extra flavor.
