Question: is parchment paper good for roasting vegetables?
Answer: Parchment paper is safe up to 420°F, so if you are roasting vegetables at a temperature above that (say 450°F or 500°F), you'll need to use foil. If you prefer slow-roasting veggies at a lower oven temperature, you can line the pan with either—though, if you do use foil, go with nonstick.
