Cube steak is a versatile cut of beef that can be cooked in many ways. One of the most popular ways to prepare cube steak is with mushroom gravy. To make this dish, you will need to season the cube steak with salt and pepper, then dredge it in flour. Brown the steak in a skillet, then remove it from the pan. In the same pan, sauté sliced mushrooms until they are tender. Add flour to the pan to make a roux, then slowly whisk in beef broth to make a gravy. Return the cube steak to the pan and simmer until it is cooked through. Serve with mashed potatoes and green beans for a classic comfort food meal.
