How can I prevent my baking tray from getting warped in the oven?

To prevent your baking tray from getting warped in the oven, make sure to use a high-quality, heavy-duty baking tray that is designed to withstand high temperatures. Avoid sudden temperature changes by allowing the tray to cool down before washing it or placing it in the oven. Additionally, avoid placing the tray directly on the oven rack, and instead use a baking sheet or parchment paper to provide a buffer.
