10-12 ounces firm fish fillets
4 tsp fresh lemon juice
2 tsp chopped fresh dill (or 3/4 tsp dried)
dash of salt and pepper
1/3-1/2 cup sour cream
2-3 thick slices red onion
Preheat the oven to 375. Rinse and dry the fish fillets and place them, skin side down, in an oiled baking pan. Sprinkle with the lemon juice, dill, salt and pepper. Spread the sour cream evenly over the fillets. Break the onion slices into rings and press them into the sour cream.
Cover the pan and bake until the fish is no longer translucent and flakes easily with a fork. The amount of time varies with the thickenss of the fish, but it usually takes 25 to 30 minutes.
