Sure. The black containers we use are safe in your conventional oven (not a toaster oven) for up to 45 minutes at 400 degrees (be sure to remove all of the plastic cover before placing in the oven). All other plastic containers we use are obviously not safe for either the oven or the toaster oven, but you can easily move meals into oven safe ware for reheating. For the toaster oven, all meals need to be removed from our packaging and placed in toaster oven safe ware. With most of our meals, you’ll get better results reheating in an oven if you loosely cover the meal with foil during reheating.
