serves 4

8 tilapia fillets (fresh or thawed)
4 tablespoons unsalted butter
2 tablespoons freshly squeezed lemon juice
salt and pepper to taste
1/4 - 1/2 teaspoon dried chervil (see note below)

Preheat oven to 375F.  Spray a 9x13-inch casserole dish with nonstick cooking spray.  Place fish fillets in a single layer, overlapping slightly.  Sprinkle with salt and pepper.  Melt butter and stir in lemon juice; pour over fillets.  Bake uncovered for 10-15 minutes or until the internal temperature in the thickest part of the of the fillet reaches 140F.  Remove casserole dish from oven and sprinkle fillets with dried chervil; rest 5 minutes before serving. 

Note:  Chervil, which is related to parsley, has a delicate flavor and is used extensively in French cuisine.  Parsley may be substituted.
