My sister makes this 4 ingredient classic for Sunday dinners and the meat is always so tender

This Oven Baked 4-Ingredient Sour Cream Swiss Steak turns budget-friendly cube steaks into tender, melt-in-your-mouth portions braised in a velvety gravy. A quick whisk of cream of mushroom soup, sour cream, and dry onion soup mix creates a rich, savory sauce that smothers the beef as it bakes to low-and-slow perfection.

Oven Baked 4-Ingredients Sour Cream Swiss Steak

Ingredients:

Step-By-Step Directions:

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

2. Prep beef: Pat the steaks dry with paper towels. Slice into serving pieces if necessary and season lightly with salt and black pepper if desired. Lay the steaks in a single layer in the prepared baking dish.

3. Whisk sauce: In a medium bowl, whisk together the condensed cream of mushroom soup, sour cream, and dry onion soup mix until smooth and fully combined.

4. Smother steaks: Pour the sour cream mixture evenly over the steaks, spreading it with a spatula to make sure all pieces of meat are well coated.

5. Cover and braise: Cover the casserole dish tightly with aluminum foil. Bake in the preheated oven for 1 1/2 to 2 hours, until the beef is fork-tender.

6. Adjust sauce and serve: Carefully remove the foil. Gently stir the gravy around the steaks to recombine. Return to the oven uncovered for 10 to 15 minutes if you prefer a thicker sauce. Spoon the steaks and plenty of rich gravy onto plates and serve warm.
