One of my favorites growing up Mom made us. Very simple easy to prepare. Now all of my cooking is usually done either in cast iron or on the grill. Or even both, the grill is an under utilized tool in most homes. In this instance I would also consider putting my cast iron skillet on the grill instead of in the oven.
To make the cube steak:
First rinse the cube steaks with water, next cover them in a simple flour breading or use a preseason mix. I use Kentucky Kernel seasoned flour.
Second warm cooking oil of your choice (I prefer olive oil) over medium heat cast iron pan. Brown both sides of the cube steaks. Once browned, place the cube steaks in cast iron skillet with a lid or any covered dish you have. Preheat oven to 350 degrees.
Third pour 1 can of Campbell’s mushroom gravy over the cube steaks also pour 1 cup of milk over. mix and coat all the cube steaks.
Last place the covered dish in the oven for 1 hour, remove after 1 hour and serve.
