Ingredients (Serves 6)

• 2 to 2½ pounds beef cube steak or round steak, tenderized
• 1 (10.5 oz) can cream of mushroom soup
• 1 cup sour cream
• 1 packet dry onion soup mix
• 1 tablespoon oil or butter (for greasing, optional)
• Salt and black pepper, to taste (optional)

Step-by-Step Instructions

1. Preheat the Oven

Set your oven to 325°F (165°C). Lightly grease a 9×13-inch casserole dish with oil, butter, or nonstick spray.

2. Prepare the Steak

Pat the beef dry. If using round steak, cut into serving-sized pieces and tenderize lightly. Season with salt and pepper if needed.

3. Arrange the Meat

Place the steaks in a single layer in the baking dish. Slight overlapping is fine since the sauce will fully coat and tenderize the meat.

4. Make the Creamy Sauce

In a bowl, whisk together the cream of mushroom soup, sour cream, and onion soup mix until smooth and well blended.

5. Coat the Steak

Pour the creamy mixture evenly over the beef, making sure each piece is fully covered for maximum flavor and tenderness.

6. Bake Low and Slow

Cover tightly with foil and bake for 1½ to 2 hours, until the steak becomes fork-tender.

7. Adjust the Gravy

Remove foil carefully and stir the sauce.

• If too thin: bake uncovered for 10–15 minutes
• If too thick: add a splash of warm water or beef broth

8. Serve and Enjoy

Serve hot with creamy mashed potatoes, egg noodles, or rice. Add a side of green beans, roasted vegetables, or a fresh salad for a complete meal.
