Can you put a top on cornning ware in the oven?

CorningWare is designed to be used uncovered in the oven, allowing heat to circulate freely and cook food evenly.

Adding a lid can trap steam, causing uneven cooking, potential for burning, or even breakage of the dish due to pressure build-up.

Here's why it's not recommended:

* Uneven cooking: The steam trapped under the lid can make some parts of the food overcook while others remain undercooked.

* Potential for burning: The steam can also cause food to burn or stick to the bottom of the dish.

* Pressure buildup: The trapped steam can create pressure that can cause the dish to crack or break.

Instead of using a lid, consider these options:

* Use a baking sheet: You can use a baking sheet to catch spills and splatters.

* Cover with foil: You can cover the dish loosely with foil to prevent splattering, but be sure to leave some space for steam to escape.

* Use a different dish: If you need a covered dish, you can use a different type of oven-safe dish.

Always follow the manufacturer's instructions for using CorningWare and other cookware.
