  • 1/2 cup sour cream

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C). Meanwhile, gather your ingredients so nothing gets left behind.
  2. In a large bowl, place the lump crab meat and the peeled, deveined shrimp. Then add the cooked rice and shredded cheddar.
  3. Next, spoon in the mayonnaise and sour cream. Add the chopped onion, minced garlic, and both bell peppers. Mix gently, because you want the crab to stay in nice chunks.
  4. Pour in the Worcestershire sauce and lemon juice, and sprinkle the Old Bay, salt, and pepper. Stir until everything looks creamy and well combined.
  5. Transfer the mixture to a greased 9x13-inch baking dish and spread it evenly.
Baking
  1. In a small bowl, mix the breadcrumbs with the melted butter. Then sprinkle this buttery topping evenly over the casserole.
  2. Bake on the middle rack for 25–30 minutes, or until the top turns golden brown and the casserole bubbles at the edges.
  3. Remove from the oven and let it rest for a few minutes. Finally, scatter the chopped parsley over the top for a bright finish.

Notes

Use leftover rice or quick-cook rice to speed things up. If the casserole seems dry after baking, stir in a splash of cream or a tablespoon of mayo, then warm it briefly. Consider adding smoked paprika or swapping cheddar for Monterey Jack for a different flavor.
