Method
 

Preparation
  1. Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking dish.
  2. In a large bowl, combine lump crab meat and shrimp. Fold in cooked rice and shredded cheddar until slightly chunky.
  3. Add mayonnaise, sour cream, chopped onion, minced garlic, green and red bell peppers, Worcestershire sauce, lemon juice, Old Bay seasoning, salt, and pepper. Mix gently to keep crab pieces intact.
Assembly
  1. Transfer the mixture to the prepared baking dish and spread evenly. The surface should be level but not packed tight.
  2. In a small bowl, mix breadcrumbs with melted butter until coated. Sprinkle over the casserole.
Cooking
  1. Bake for 25–30 minutes until the top is golden brown and the filling bubbles at the edges.
  2. Remove from the oven, let it rest for a few minutes. Sprinkle with fresh parsley and serve warm.

Notes

Time-saver: Use pre-cooked shrimp to cut prep time. If the casserole seems too wet, add more rice or cheese. Stir in a teaspoon of Dijon mustard or smoked paprika for extra flavor.
