2 cups cooked rice

1 tsp paprika

1 tsp Old Bay seasoning

Salt and pepper, to taste

Step-by-Step Instructions
-
Preheat the Oven: Set to 350°F (175°C) for even baking and a golden top.
-
Sauté the Veggies: In a large skillet, heat a little oil over medium heat and cook bell peppers and onions until softened and fragrant, about 5–7 minutes.
-
Mix It Up: In a large bowl, combine the sautéed vegetables, crab meat, shrimp, rice, cream of mushroom soup, paprika, Old Bay, and half the cheese. Stir until everything is evenly coated.
-
Season: Taste and adjust with salt and pepper as needed.
-
Fill the Dish: Transfer the mixture into a greased casserole dish, smoothing it into an even layer.
-
Cheese Topping: Sprinkle the remaining cheddar over the top.
-
Bake: Cook for 25–30 minutes until bubbling hot and golden on top.
-
Garnish & Serve: Let it rest a few minutes, then finish with parsley for a fresh pop of color.
Serving Suggestions
Pair your Crab and Shrimp Casserole with a crisp green salad and light vinaigrette to balance the richness. Garlic bread or crusty rolls are perfect for scooping up every last bit of sauce. For drinks, iced tea or lemonade makes a refreshing match.
Top Tips for Success
-
Seafood swaps: Try scallops, lobster, or even chicken if crab and shrimp aren’t available.
-
Extra creamy: Add a splash of heavy cream before baking for a richer texture.
-
Prevent over-browning: If the cheese starts browning too quickly, cover with foil for the rest of the bake.
Storage & Reheating
-
Fridge: Store leftovers in an airtight container for up to 3 days.
-
Freezer: Freeze for up to 2 months.
-
Reheat: Oven at 350°F until warmed through is best for texture, though the microwave works for single portions.
