Ingredients

  • 3 cups sliced mushrooms
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 1 pound sole or lean fish fillet
  • 1/2 cup dry white wine
  • 1/3 cup coarsely crushed zwieback cookies
  • 1/4 cup sliced green onions and tops
  • 3 tablespoons snipped fresh cilantro or 1 tablespoon dried
  • 2 tablespoons reduced-calorie margarine

Instructions

  1. Preheat oven to 425°F.
  2. Place sliced mushrooms in an ungreased 12 x 7 1/2 x 2-inch baking dish.
  3. Sprinkle mushrooms with 1/4 teaspoon salt and pepper.
  4. Arrange fish fillets over the mushrooms.
  5. Sprinkle fish with remaining salt and pepper.
  6. Pour white wine around the fish.
  7. Mix coarsely crushed zwieback cookies, sliced green onions, cilantro, and melted margarine.
  8. Spread this mixture over the top of the fish.
  9. Bake uncovered until fish fillets flake easily with a fork, about 15 to 20 minutes.

Tips & Substitutions

To enhance the flavor, consider using a splash of lemon juice or zest in the white wine before pouring it around the fish. If sole is unavailable, any lean white fish can be substituted. For a crunchier topping, mix in some breadcrumbs with the zwieback cookies. Fresh herbs can also be varied; dill or parsley work well instead of cilantro.

Serving Suggestions

Serve the sole gratin with a side of steamed vegetables or a fresh green salad for a light meal. A crisp white wine, such as Sauvignon Blanc, pairs beautifully. For a heartier option, try serving it alongside garlic mashed potatoes or a quinoa salad. This dish complements other seafood recipes well, making it a versatile addition to your meal rotation.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place in a preheated oven at 350°F for about 10-15 minutes until warmed through, ensuring the fish remains moist. Avoid microwaving to prevent the fish from drying out.

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 ensure even cooking and proper texture. Pat them dry to remove excess moisture, which can affect the final dish.

What can I use instead of zwieback cookies?

If zwieback cookies are not available, you can substitute with crushed saltines or panko breadcrumbs. They will provide a similar crunch and texture. Adjust the seasoning accordingly, as some alternatives may be saltier.

How do I know when the fish is done cooking?

The fish is done when it flakes easily with a fork and is opaque in color. This usually takes about 15 to 20 minutes at 425°F. For best results, check the fish at the 15-minute mark to avoid overcooking.
