Preheat the oven to 400°F (200°C).

In a mixing bowl, combine your peeled and deveined shrimp with minced garlic, fresh lemon juice, salt, and pepper. Toss together to coat the shrimp.

Melt about a quarter cup of unsalted butter in a small saucepan over low heat. Stir in half of the grated Parmesan cheese until smooth.

Pour the butter and cheese mixture over the shrimp and toss to coat. Spread shrimp in a single layer on a lined baking sheet.

Roast the shrimp in the preheated oven for 8-10 minutes until they turn pink and opaque.

Sprinkle remaining Parmesan cheese and chopped parsley on top before serving.
