Cube steak can be used in a hearty casserole with potatoes and vegetables. To make this dish, you will need to season the cube steak with salt, pepper, and garlic powder. Brown the steak in a skillet, then remove it from the pan. In the same pan, sauté sliced onions and garlic until they are tender. Layer sliced potatoes, carrots, and green beans in a baking dish, then top with the browned cube steak. Pour beef broth over the top, then cover the dish with foil and bake in the oven for 45-60 minutes, or until the vegetables are tender. Remove the foil and bake for an additional 10-15 minutes, or until the top is golden brown and crispy.
