  • 2 cups cooked fish, crab, or shrimp
  • 1/2 cup chopped red or green pepper
  • 1/2 cup onions
  • 1/2 cup chopped celery

  • 1 can mushroom soup or shrimp soup
  • 1/2 cup grated cheese

  5. Chill the casserole overnight or for 2 to 3 hours.
  6. Bake at 325°F (160°C) for 1 hour.
  7. Sprinkle grated cheese over the top and bake a few extra minutes until melted.

Tips & Substitutions

For a twist, consider using leftover shrimp from Shrimp Dip (Hot Or Cold) or substituting the seafood with crab for a richer flavor. If you want a lighter version, opt for low-fat milk and reduced-fat cheese. Ensure the bread is slightly stale for better absorption of the custard mixture, which enhances the texture of the casserole.

Serving Suggestions

This casserole is delightful served with a fresh green salad or steamed vegetables for a balanced meal. Pair it with crusty bread to soak up the delicious sauce. For a complete seafood-inspired dinner, consider serving alongside Ruth'S Shrimp Salad for a refreshing contrast.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to three days. To reheat, place the casserole in a preheated oven at 350°F (175°C) for about 20-30 minutes or until heated through. Cover with foil to prevent over-browning while reheating.

Frequently Asked Questions

Can I use frozen seafood in this casserole?

Yes, you can use frozen seafood, but make sure to thaw and drain it well before adding it to the casserole. This prevents excess moisture that could affect the final texture. Just ensure that it's fully cooked before incorporating it into the dish.

What kind of bread works best for this recipe?

While white bread is traditional, you can also use whole grain or sourdough for added flavor and texture. Just make sure the bread is not too soft, as it needs to hold up under the custard mixture.

Can I make this casserole ahead of time?

Absolutely! You can prepare the casserole up to the point of baking, cover it tightly, and refrigerate it overnight. This allows the flavors to meld. Just add a few extra minutes to the baking time if baking straight from the fridge.
