Ingredients

  • 2 lb. frozen fish (cod or halibut)
  • 1 c. sour cream
  • 1/2 c. grated Swiss cheese
  • 1/4 c. finely chopped onion
  • 3/4 tsp. salt
  • 1/4 tsp. pepper
  • 1 tsp. mustard

Instructions

  1. Arrange fish fillets in a lightly greased 2 1/2-quart shallow baking pan.
  2. In a small bowl, combine sour cream, grated Swiss cheese, chopped onion, salt, pepper, and mustard.
  3. Spread the mixture evenly over the fish fillets.
  4. Bake at 425°F for 20 minutes or until the fish flakes easily.

Tips & Substitutions

For a lighter version, consider using Greek yogurt instead of sour cream. If you're short on time, you can use fresh fish fillets instead of frozen, adjusting the baking time accordingly. To enhance the flavor, add some fresh herbs like dill or parsley to the sour cream mixture. This dish is also excellent with a sprinkle of lemon juice before serving.

Serving Suggestions

Serve the baked fish fillets alongside steamed vegetables or a fresh salad for a balanced meal. The dish pairs beautifully with Alberta Salad for a refreshing contrast. A side of rice or quinoa can also complement the creamy sauce well. Consider serving with a light white wine to enhance the flavors.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place the fish in a baking dish and cover with foil to prevent drying out. Bake at 350°F for about 10-15 minutes, or until heated through. Avoid microwaving, as it can make the fish rubbery.

Frequently Asked Questions

Can I use a different type of cheese?

Yes, you can substitute the Swiss cheese with other varieties like Gruyère or mozzarella. Each cheese will bring a different flavor profile to the dish. Just ensure the cheese melts well and complements the creamy sauce.

Is it possible to prepare this dish in advance?

Absolutely! You can assemble the fish and sour cream mixture a few hours ahead of time and keep it covered in the refrigerator. Just bake it when you're ready to serve for a quick and easy meal.

What should I do if my fish is still frozen?

If your fish fillets are still frozen, it's best to thaw them in the refrigerator overnight before preparing the recipe. If you're short on time, you can also run them under cold water in a sealed bag until thawed, then proceed with the recipe.
