Old Bay Crab and Hash Brown Breakfast Casserole
Savory seafood breakfast casserole layering crispy hash browns, lump crab, and a custardy egg mixture seasoned with Old Bay spice. Golden, cheesy, and substantial enough for brunch entertaining or special weekend mornings. The crab stays tender while hash browns crisp at the edges, and Old Bay provides the coastal backbone throughout. Serve warm with toast and coffee.

Tips
Do not thaw hash browns before mixing; cold shreds distribute more evenly and prevent clumping in the cream cheese layer.
Check doneness by inserting a knife at the 45-minute mark; if liquid still pools in center, bake additional 3-5 minutes rather than relying solely on color.
Slice into portions while warm for clean edges; the casserole firms considerably as it cools.
Good to Know
Cover and refrigerate up to 3 days. Reheat covered at 325F for 15-20 minutes until warmed through.
Assemble through egg mixture pour the evening before; refrigerate covered. Bake directly from cold, adding 10-15 minutes to baking time.
Warm from the oven with crusty bread, fresh fruit, or a simple salad. Pairs well with mimosas or Bloody Marys.
Common Mistakes
Do not skip pressing hash brown layer firmly to prevent separation during baking.
Do not over-thaw hash browns; excess moisture will make the base soggy.
Do not skip the 10-minute rest; it allows the custard to set completely and makes serving cleaner.

FAQ
Can I make this ahead?
Yes. Assemble through the egg mixture step, cover, and refrigerate overnight. Bake directly from cold, adding 10-15 minutes to cook time. Do not freeze assembled casserole as the egg custard does not thaw evenly.
What if I don't have fresh lump crab?
Canned or frozen lump crab works well; thaw frozen and drain thoroughly. Pasteurized crab lasts longer and offers consistent flavor. Jumbo lump gives more impressive texture but costs more.
How long does it keep after baking?
Refrigerate covered up to 3 days. Reheat covered at 325F for 15-20 minutes until warmed through. Not recommended for freezing; custard and crab texture degrade.
