Made from material that will change what you think is possible, UltraPro Ovenware is safe for the oven, microwave, fridge and freezer and is beautiful on the table. Save time by tandem cooking: starting in the microwave and finishing to a golden brown in the oven. For beautiful casseroles, lasagnas, roasted vegetables and more. It’s the same length and width as the 6-Qt./5.7 L Roasting Pan with Cover, so it stacks nicely with those pieces as well. • In Cosmos. • Dishwasher safe. • All Tupperware is BPA Free
