Cook Dover sole fillets simply with a minimum of seasonings such as salt, pepper and olive oil. Dover sole has a delicate buttery taste that does not require much modification. The fish has a thin texture and can be baked or pan-fried. Turn fish carefully so it does not break apart.
An easy recipe for Dover sole starts with preheating an oven to 425 degrees Fahrenheit. Drizzle olive oil over sole fillets, and place in a greased roaster pan. Season fillets with salt and pepper, and then cook for three minutes before carefully flipping fish. Cook for another five minutes, or until opaque, but still moist.
Dover sole can also be used to make Sole Parmesan. For this dish, combine 1/2 cup grated Parmesan cheese, 3 tablespoons soft butter, 1/8 teaspoon cayenne pepper, 2 tablespoons sliced green onions, 1 teaspoon grated lemon rind and 3 tablespoons mayonnaise in a bowl. Next, place 1 1/2 pounds sole fillets on a greased broiler pan, and drizzle with 2 tablespoons lemon juice.
Preheat the broiler, and arrange racks 3 to 4 inches from the element. Broil fish for three to five minutes or until flaky. Cover fish in Parmesan mixture, and return to the oven. Broil for another three minutes, or until bubbly and golden.
