Oven-Baked 4-Ingredient Creamy Mushroom Beef Bake

Ingredients:

Step-By-Step Directions:

1. Preheat and prep: Preheat your oven to 300°F (150°C) and lightly grease a 9×13-inch glass casserole dish with cooking spray or oil.

2. Layer the beef: Spread the raw beef stew meat in an even layer across the bottom of the dish, separating any pieces stuck together.

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

4. Pour over beef: Pour the soup mixture evenly over the beef in the baking dish, using a spatula to ensure all meat is coated and sauce reaches the edges.

5. Bake covered low and slow: Cover the dish tightly with aluminum foil and bake for 2 1/2 to 3 hours, until the beef is fork-tender and the sauce turns into a rich gravy.

6. Rest and serve: Remove the foil carefully, give the mixture a gentle stir to re-coat the beef, and let rest for 5 minutes before serving warm over noodles, rice, or mashed potatoes.
