Ingredients

  • 1 lb. sealegs
  • 7 slices bread, crust removed, cut into 1/2-inch strips
  • 1/2 cup chopped onion
  • 1/2 cup chopped green pepper
  • 1/2 cup chopped celery
  • 1 cup grated cheese
  • 4 eggs
  • 1 can cream of mushroom soup
  • 1 cup milk

Instructions

  1. Grease a casserole dish and line the bottom with half of the bread strips.
  2. Mix together sealegs, chopped onion, chopped green pepper, and chopped celery. Spoon over the bread layer.
  3. Add the remaining bread strips to form the top layer.
  4. Beat the eggs and add them to the milk.
  5. Stir the cream of mushroom soup into the milk mixture.
  6. Pour the soup and milk mixture over the layered bread and seafood.
  7. Top with grated cheese.
  8. Bake at 350°F (175°C) for 45 to 60 minutes until bubbly and golden.

Tips & Substitutions

For added flavor, consider using sautéed mushrooms or garlic in the vegetable mix. If sealegs are unavailable, imitation crab or shrimp can be great substitutes. To enhance the dish's creaminess, try using a blend of cream cheese and sour cream instead of just the cream of mushroom soup. This casserole can also benefit from a sprinkle of Old Bay seasoning for a seafood kick.

Serving Suggestions

This Sealeg Casserole pairs beautifully with a fresh green salad or roasted vegetables for a complete meal. Consider serving it alongside a side of mashed potatoes and spinach for a hearty dinner. For a delightful finish, a slice of Pineapple Dump Cake could make a perfect dessert after this savory dish.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a preheated oven at 350°F (175°C) until warmed through, about 20-25 minutes. Alternatively, microwave individual portions on medium power for 1-2 minutes, ensuring even heating.

Frequently Asked Questions

Can I prepare the casserole ahead of time?

Yes, you can assemble the casserole a day in advance. Cover it tightly with plastic wrap and refrigerate. When ready to bake, remove the wrap and let it sit at room temperature for about 30 minutes before placing it in the oven to ensure even cooking.

What type of cheese works best for this recipe?

Cheddar cheese is a popular choice due to its rich flavor and good melting properties. However, feel free to experiment with other cheeses like Monterey Jack or a blend of Italian cheeses for a different taste. Just ensure the cheese is grated to allow for even melting.

Can this recipe be made gluten-free?

Absolutely! You can use gluten-free bread for the layers. Additionally, check that the cream of mushroom soup is gluten-free or consider making your own with gluten-free ingredients. This way, you can still enjoy the casserole without the gluten.
