Preheat your oven to 350°F.

In a large mixing bowl, combine the shrimp with salt and pepper.

In a skillet over medium heat, melt 1 tablespoon of butter and sauté the onion, celery, bell pepper, and garlic until softened.

In the same bowl with the shrimp, add the sautéed vegetables, rice, bread crumbs, parsley, paprika, and cream of mushroom soup. Combine everything until well mixed.

Spread the shrimp mixture evenly in the baking dish.

Sprinkle shredded cheddar cheese on top of the shrimp mixture, then drizzle melted butter over everything.

Bake in the preheated oven for 30 minutes or until bubbly and golden.

Once done, remove from the oven and let it rest for about 5 minutes before serving.
