If you don’t already have a cast iron skillet, go get one! Kidding. But they really do come in handy and cook food in a way regular pans just don’t do. However, if you don’t have one on hand, no worries! You can use a regular pan or skillet to sear the pork chops and cook the gravy and onions. You will need to then transfer everything to a baking dish for the oven portion. No longer a one pot recipe but an extra dish never hurt anyone.
