Ingredients

  • 2 medium green peppers
  • 2 medium onions
  • 2 medium tomatoes
  • 2 (1 lb.) packs boneless fish
  • salt to taste

Instructions

  1. Layer the green peppers, onions, tomatoes, and fish in a buttered casserole dish.
  2. Dot each layer of fish with butter.
  3. Bake at 325°F (160°C) for 35 to 40 minutes until cooked through.

Tips & Substitutions

For added flavor, consider marinating the fish in lemon juice and herbs before layering. If you don't have green peppers, yellow or red peppers can work just as well. You can also use fresh herbs like parsley or dill to enhance the dish. If you prefer a creamier texture, layer in some cheese or a light cream sauce, similar to what's used in a Deviled Seafood Casserole.

Serving Suggestions

This fish casserole pairs beautifully with a simple green salad or steamed vegetables for a light meal. Consider serving it with a side of crusty bread to soak up the flavors. For a comforting addition, creamy mashed potatoes or rice can complement the dish nicely. You can also explore other seafood recipes like Tuna Patties for more variety.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a preheated oven at 325°F (160°C) for about 20 minutes or until heated through. You can also microwave individual portions, but be careful not to overcook the fish to maintain its texture.

Frequently Asked Questions

Can I use a different type of fish for this casserole?

Absolutely! While the recipe calls for boneless fish, you can substitute it with other types like cod, tilapia, or even salmon. Just ensure the fish is boneless and has a similar cooking time to avoid overcooking. Each type will offer a unique flavor profile to the dish.

Is it possible to make this casserole ahead of time?

Yes, you can prepare the casserole a day in advance. Just assemble all the layers in the dish, cover tightly with plastic wrap, and refrigerate. When ready to bake, remove it from the fridge and let it sit at room temperature for about 15 minutes before baking to ensure even cooking.

What can I do if I have leftover casserole?

Leftover fish casserole can be creatively repurposed. Try flaking the fish and mixing it into a pasta dish, or use it as a filling for a savory pie. You can also blend it into a dip, similar to a Tuna Vegetable Dip, served with crackers or veggies for a different meal.
