While flounder is a favorite, use any firm fleshed fish such as tilapia, grouper, or catfish. Adjust the cooking time according to the thickness of the fish.
1/4 cup grated Parmesan cheese
1 tsp. paprika
4 (6 oz.) flounder fillets
3/4 tsp. salt
1/4 tsp. pepper
1/2 cup butter
2 Tbsp. fresh lemon juice
Place 1 oven rack 5 inches from heat; place a second rack in the middle of oven. Combine Parmesan cheese and paprika. Season fish with salt and pepper.
Preheat oven to 450 degrees. Heat butter in a broiler-safe 13 x 9 inch baking dish in oven 8 minutes or until butter is melted and beginning to brown. Place fish in hot butter, skin side up.
Bake at 450 on middle oven rack 10 minutes. Carefully flip fish; baste with pan juices. Sprinkle with lemon juice and Parmesan cheese mixture. Bake 5 more minutes or just until fish flakes with a fork. Remove from oven, increase oven temperature to broil.
Broil fish on oven rack 5 inches from heat 2 to 3 minutes or until bubbly and golden brown.
