It’s a question that comes up often, and not just in cooking circles: Can you put styrofoam in the oven? The short answer is yes. Styrofoam is a type of plastic foam made from polystyrene beads, which makes it heat-resistant like other plastics. It can be used to line baking sheets so that food doesn’t stick or to make disposable containers for takeaway meals.

However, there are some caveats when it comes to using this material in the oven. The first thing you should know about putting styrofoam in the oven is that all types of styrofoam will expand once heated—even if they’re labeled “low density.” This means that anything you line your pan with will need to be loose and flexible enough to allow for this expansion.

The second thing you should know is that styrofoam can melt when heated too high or left on the oven rack without anything in it, so make sure not to leave any pieces of food out during cooking. By itself, a piece of expanded foam could potentially catch fire if it comes into contact with an open flame; however, as long as your dish doesn’t contain any flammable ingredients (like butter or oil), then there shouldn’t be anything hazardous about leaving some non-flammable insulation behind while prepping your tasty treat. Tips: * Make sure you’re using foil aluminum baking sheets—not steel ones! Steel conducts heat more quickly
