Tips
Crab meat selection affects texture and flavor; lump crab provides larger pieces while claw meat is more affordable.
Gently stir the bread and milk mixture to avoid compacting the bread pieces.
The recipe uses half the original butter amount; adjust upward if the mixture appears too dry after mixing.
Good to Know
Cover and refrigerate up to 3 days. Reheat at 325 degrees Fahrenheit until warmed through.
Assemble casserole up to 8 hours ahead; refrigerate covered. Bake just before serving.
Serve warm directly from the casserole dish.
Common Mistakes
Do not overstir the bread and milk mixture to avoid creating a dense, gluey texture.
Do not skip the paprika topping, which adds color and suggests Old Bay depth.
Do not bake longer than 45 minutes to avoid a dry, rubbery casserole.
