Here's a buttery, lemony baked white fish recipe that only takes a few minutes and tastes great. Use any white fish you have - haddock, orange roughy, whatever. If you have some small brown paper lunch bags on hand, perfect--if not, cut up a large brown paper grocery bag.
Preheat the oven to 350. For each person, use 2 fillets, of about equal size/thickness. Cut the bag so it's one flat piece, lay it on a baking sheet with an edge, and brush the bag with just enough vegetable oil to coat. If you've thawed the fish, drain it first on paper toweling so its not waterlogged and wet. Lay one fillet on the paper, and sprinkle with 1/2 to 1 tsp lemon juice, depending on fillet size. Sprinkle generously with garlic powder and paprika. Top with 2-4 thin slices of cold butter. If limiting fat, you can use Smart Beat or a similar butter-substitute product and smear it on. Lay the next fillet crosswise over it and repeat the steps.
Slice a lemon into 6-8 slices, and cover the fish pile, pinning the lemon slices with toothpicks. Pull the edges of the bag closed, folding them under to make a loose package- it does not need to be airtight. Place package on baking sheet in the oven for 30-40 minutes, depending on the size and thickness of the fish.
We had this tonight with blueberry cole slaw, and thought it had lots of buttery. lemony flavor.
