Parchment paper is generally safe in a gas oven when used correctly, though some caution is warranted. The key concern is temperature: parchment paper typically has a maximum safe temperature of 400–450°F (200–230°C), depending on the brand. Gas ovens that maintain steady, even heat within this range pose no problem. However, parchment paper can scorch or ignite if it comes into direct contact with a gas flame or burner element, or if oven temperatures exceed its heat rating.
To use parchment paper safely in a gas oven, keep it away from the heating elements at the bottom and sides of the oven. Line baking sheets rather than placing it directly on oven racks. Check your parchment's heat rating before use, as some premium brands tolerate higher temperatures. Silicone-coated parchment is more heat-resistant than bleached parchment and may be a better choice if you regularly bake at higher temperatures.
Alternatively, you can use aluminum foil, which is universally safe in gas ovens, or simply use well-seasoned cast iron or quality baking sheets. Many bakers prefer avoiding parchment in gas ovens simply to eliminate any small risk, though millions use it safely daily. If you choose parchment paper, monitor your oven and don't exceed the manufacturer's temperature recommendation.
