Ingredients

  • 1 lb fish fillets
  • 2 Tbsp margarine
  • 1/2 tsp lemon juice
  • 2 green onions
  • 1/2 cup sliced mushrooms
  • 1 tomato
  • 1/2 tsp salt

Instructions

  1. Arrange fish fillets in a 12 x 7 x 2-inch microproof baking dish with the thick edges toward the outside of the dish.
  2. Dot the fish fillets with margarine.
  3. Sprinkle lemon juice, green onions, mushrooms, tomatoes, and salt over the fillets.
  4. Cover with waxed paper.
  5. Cook on maximum power for 5 minutes.
  6. Let stand, covered, for 5 minutes before serving.

Tips & Substitutions

For a richer flavor, consider using butter instead of margarine. You can substitute the fish fillets with any firm white fish like cod or tilapia. If green onions are unavailable, regular onions can work in a pinch, though they may be stronger in flavor. Feel free to add herbs such as parsley or dill for an extra layer of freshness.

Serving Suggestions

Serve the fish fillets with a side of steamed vegetables or a fresh salad for a light meal. A squeeze of fresh lemon juice over the top can enhance the flavors. This dish pairs beautifully with sides like rice or quinoa. For a heartier option, consider making a batch of Family-Style Salmon Croquettes as a complementary dish.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place the fish fillets in a microwave-safe dish, cover loosely with a damp paper towel, and heat in short intervals until warmed through. Avoid overcooking, as the fish can dry out quickly.

Frequently Asked Questions

Can I use frozen fish fillets for this recipe?

Yes, you can use frozen fish fillets. Just ensure they are completely thawed before cooking to achieve even cooking. You may need to adjust the cooking time slightly if the fillets are particularly thick.

What can I use instead of mushrooms?

If you’re not a fan of mushrooms, you can substitute them with diced bell peppers or zucchini for added texture and flavor. Both options will complement the fish well and maintain the dish's freshness.

How can I make this dish spicier?

To add a kick to the dish, consider sprinkling some red pepper flakes or adding sliced jalapeños along with the other toppings. This will give a nice heat that balances well with the lemon and creaminess of the margarine.
