It is important to know if your cookware is oven safe before using it in the oven. Here are a few tips on how to tell if stainless steel is oven safe:
1. Check the manufacturer's instructions. Oftentimes, the manufacturer will specify on the packaging or in the product manual if the cookware is oven safe.
2. Look for a symbol. Some cookware has a symbol of an oven on it, which indicates that it is oven safe.
3. Check the construction. If the cookware is made of multiple layers of stainless steel, it is likely oven safe.
4. Test it out. Place the cookware in a cold oven and then preheat the oven to the recommended temperature. If the cookware becomes warped or distorted, it is not oven safe.
Keep in mind that even if a piece of stainless steel cookware is oven safe, it may not be safe to use under the broiler. Be sure to check the manufacturer's instructions to be sure.
