  • 1 cup soft bread crumbs

  3. Spoon the mixture into a 1-quart casserole or four individual baking shells.
  4. Combine 1 cup bread crumbs with melted butter and sprinkle around the edge of the casserole.

Tips & Substitutions

For a richer flavor, consider using fresh crab if available. If you’re short on time, pre-packaged seafood salad dressing can be a quick substitute for mayonnaise. Adding a pinch of cayenne or Old Bay seasoning can enhance the dish's flavor profile. Be cautious not to overmix the seafood to maintain a chunkier texture, similar to what you’d find in classic seafood recipes.

Serving Suggestions

This Crab-Lobster Casserole is delightful served with a light green salad or steamed vegetables for a well-rounded meal. A crisp white wine or a light beer complements the seafood flavors beautifully. For a heartier option, pair it with garlic bread or a side of Mom'S Scalloped Oysters. It also makes for an impressive dish at gatherings.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in a preheated oven at 350°F for about 15-20 minutes until heated through. Avoid microwaving, as it may result in a rubbery texture. For best results, cover with foil to prevent drying out.

Frequently Asked Questions

Can this casserole be made ahead of time?

Yes, you can prepare the casserole up to a day in advance. Assemble everything, cover tightly, and refrigerate. When ready to bake, allow it to sit at room temperature for about 30 minutes before placing it in the oven. This ensures even cooking and helps achieve that perfect golden crust.
