- 1 (1-ounce) packet dry onion soup mix
- ½ cup water
Instructions
1. Prepare the Oven
Preheat your oven to 300°F (150°C). Lightly grease a 9×13-inch baking dish with cooking spray or a little oil.
2. Add the Beef
Spread the beef stew meat evenly across the bottom of the baking dish, separating any large pieces for even cooking.
3. Make the Creamy Sauce
In a mixing bowl, whisk together the cream of mushroom soup, onion soup mix, and water until smooth and well combined.
4. Assemble
Pour the creamy mushroom mixture evenly over the beef, making sure every piece is coated.
5. Bake
Cover the baking dish tightly with aluminum foil. Bake for 2½ to 3 hours, or until the beef is fork-tender and the sauce has thickened into a rich, creamy gravy.
6. Serve
Let the casserole rest for 5 minutes before serving. Stir gently, then spoon the creamy beef over mashed potatoes, rice, or buttered egg noodles.
