Parchment paper is designed to be heat-resistant and can withstand high temperatures in the oven. However, its resistance to heat varies depending on the brand and quality of the parchment paper. Generally, most standard parchment papers are safe to use at temperatures up to 420°F to 450°F (215°C to 232°C). Some higher-quality parchment papers can withstand even higher temperatures.
If the oven temperature exceeds the safe limit of the parchment paper, it may start to brown, smoke, or even ignite in extreme cases. The exact temperature at which parchment paper will burn quickly can vary, but it's essential to avoid pushing the paper beyond its recommended temperature range to prevent any potential hazards.
To be safe, always check the packaging or manufacturer's instructions of the parchment paper you're using to determine its specific heat resistance. If you need to use higher temperatures for baking or cooking, consider using alternatives like silicone baking mats or aluminum foil, which can handle higher heat levels.
