Wax paper is coated with wax and is primarily intended for uses such as food preparation, separating layers, wrapping, and certain storage applications.
It is not a substitute for parchment paper in a hot oven.
Putting wax paper in the oven can cause the wax coating to melt, smoke, and potentially create a fire hazard.
If you’re standing in the kitchen holding a roll of paper and thinking, “These look basically identical,” check the label before putting it anywhere near an oven.
Trust me on this one!
What Can You Use Instead of Parchment Paper?
If you’re cooking at a temperature above your parchment’s rating—or simply don’t want to use parchment—you have plenty of options.
Silicone Baking Mats
Reusable silicone baking mats can be excellent for cookies and other baked goods when they’re rated for the temperature you’re using.
Again, check the manufacturer’s maximum temperature.
