An ovenproof skillet should be made from very sturdy materials that will not crack or warp when exposed to high heat. You may want to cover some dishes while cooking, so a lid that fits tightly can be helpful. The pan should not be either too shallow or too deep but the length and width of this skillet can depend on what you may want to use it for. It can be a good idea to choose one that has been seasoned at the factory, as this can help keep food from sticking.
Cast iron is generally a good choice for an ovenproof skillet because this material can withstand high temperatures. You may also use stainless steel or aluminum pans provided they do not have any plastic or wooden pieces attached. Skillets with a non-stick coating could produce an offensive odor or the coating itself might melt when placed in the oven.
An ideal ovenproof skillet will have a lid specifically designed for that model. Like the skillet, this lid should not contain plastic or wooden pieces. Oven skillets with glass or cast iron lids are generally a good choice. You should make sure the lid is the right size and sits securely over the top of the skillet. It is a good idea to select one without rubber gaskets around the inside, as these pieces may crack after a few uses.
Pans that are too deep may not allow food to cook thoroughly, but those that are too shallow could cause dishes to burn easily. A good depth for an ovenproof skillet is usually somewhere between 2 and 3 inches (about 5 to 7 cm). This device can be round, square, or rectangular, and each shape comes in a variety of sizes. One that is around 9 by 13 inches (22.86 to 33.02 cm) can allow you to cook most casseroles, but a 9-inch (about 23 cm) square pan might be better for baking cornbread. A 12-inch (0.3 m) round pan is typically ideal for pizza, while an 8-inch (20.32 cm) diameter one can be best for many desserts.
Many types of skillets need to be seasoned, or coated with oil and then baked over low temperatures. It is especially important to do this when cooking with cast iron. Seasoning should be performed prior to using an ovenproof skillet, so if you are able to find one that was seasoned at the factory it could save you a great deal of time.
