Step-by-Step Instructions
Step 1: Prepare and Season Shrimp
Preheat oven to 350°F (175°C). Pat shrimp dry and season with Old Bay seasoning, salt, and pepper. Set aside while preparing other ingredients.
Step 2: Sauté the Vegetables
In a large skillet, melt butter over medium heat. Add diced onion, bell pepper, and celery. Cook for 5-7 minutes until vegetables are softened. Add minced garlic and cook for another minute until fragrant.
Step 3: Cook the Shrimp
Add seasoned shrimp to the skillet with vegetables. Cook for 2-3 minutes per side until shrimp are pink and just cooked through. Remove from heat.
Step 4: Make the Creamy Base
In a large mixing bowl, combine cream of mushroom soup, sour cream, mayonnaise, and 1 cup of shredded cheddar cheese. Whisk until smooth and well combined.
Step 5: Combine All Ingredients
Add the cooked rice, shrimp and vegetable mixture to the creamy base. Stir gently to combine, being careful not to break up the shrimp. Season with paprika and additional salt and pepper to taste.
Step 6: Assemble the Casserole
Transfer the shrimp and rice mixture to a greased 9×13 inch baking dish. Spread evenly and smooth the top.
Step 7: Add the Topping
In a small bowl, combine panko breadcrumbs, remaining cheddar cheese, and melted butter. Mix well and sprinkle evenly over the casserole.
Step 8: Bake to Perfection
Bake for 20-25 minutes until the top is golden brown and the casserole is bubbling around the edges. Let rest for 5 minutes before serving. Garnish with fresh chopped parsley.
