Magnalite manufactures aluminum roasting pans with covers for cooking large meals in a single vessel. The company makes 15- and 18-inch roasters that are rated to withstand oven temperatures of up to 350 degrees Fahrenheit. The roasters are designed to heat evenly on all sides for more efficient cooking. Magnalite roasters are commonly used for roasting whole turkeys or a large pot roast with vegetables, for example.
Rinse the pan and lid to remove any dust that may have settled on the Magnalite since the last use.
Preheat the oven no higher than 350 degrees Fahrenheit for roasting. If you must cook at higher temperatures, use a different vessel than the Magnalite.
Insert the perforated drip pan into the bottom of the roaster. The drip pan holds food off the bottom of the roasterm, allowing fat and grease to fall through.
Place the food in the roaster, cover with the lid and slide into the oven. Depending on your oven size, you may have to remove one of the wire racks so the roaster will fit. Pull the rack straight out and lift upward to release from the oven.
Roast the food in the Magnalite according to your recipe. Remove the lid from the Magnalite during the last 30 minutes of roasting to brown the food inside. If you want to achieve an attractive, golden-brown color on a holiday turkey, for example, take off the lid during the last half an hour of cooking time.
Remove the roaster from the oven by holding the two side handles while wearing hot mitts.
