Parchment paper is grease- and moisture-resistant paper specially treated for oven use. It is very versatile—use it to line cake molds and baking sheets, to wrap fish and other dishes that are cooked en papillote, and to cover countertops during messy tasks to make cleanup easy.
Simply so, can food be cooked in parchment paper?
Very simply, it’s a cooking technique that involves wrapping food, typically fish, chicken and/or vegetables in parchment paper. Once wrapped like an envelope, the “packet” is baked in the oven until the entire meal is moist, tender and cooked to perfection.
Secondly, can you use parchment paper for casseroles? Some casserole pans come with lids that are oven-safe, but you can also use aluminum foil or parchment paper for a makeshift cover. If you don’t have a lid, foil or parchment, leave the dish uncovered in the oven, but wait to put your crunchy topping on until the casserole has only 5 or 10 minutes left to cook.
