We had this meal for Ash Wednesday. It was ok, but not fabulous. It's from Recipezaar.
1 lb steelhead trout fillet
1 clove garlic, peeled
1 1/2 tbsp chopped rosemary
juice of 1 lemon
1/4 tsp salt
1/2 tsp pepper
Line a baking dish with foil and rub with olive oil. Preheat broiler.
Grind garlic, rosemary and lemon in food processor. Rub spice paste over fillet. Place fish skin-down in baking dish.
Broil on second rack from heat for 5 minutes, watching to make sure that herbs don't burn. Turn oven to 325 degrees and bake for an additional 10 minutes or until fish is cooked through.
