Ingredients
- 2 pounds beef stew meat, cut into 1 to 1½-inch cubes
- 2 (10.5-ounce) cans condensed cream of mushroom soup
- 1 (1-ounce) packet dry onion soup mix
- ½ cup water
Equipment Needed
- 9×13-inch glass baking dish
- Medium mixing bowl
- Whisk
- Aluminum foil
- Measuring cup
- Wooden spoon
Instructions
Step 1 – Prepare the Oven
Preheat your oven to 300°F (150°C). Lightly grease a 9×13-inch glass baking dish with cooking spray or a little oil.
Step 2 – Arrange the Beef
Spread the beef stew meat evenly across the bottom of the prepared baking dish, separating any pieces that are stuck together.
Step 3 – Mix the Sauce
In a medium bowl, whisk together:
- Cream of mushroom soup
- Dry onion soup mix
- Water
Mix until smooth and well combined.
Step 4 – Cover the Beef
Pour the mushroom mixture evenly over the beef, making sure every piece is coated with the creamy sauce.
Step 5 – Cover & Bake
Cover the dish tightly with aluminum foil.
Bake for 2½ to 3 hours, or until the beef is fork-tender and the gravy is thick and creamy.
Avoid opening the oven often to keep the moisture trapped inside.
Step 6 – Stir & Rest
Remove the foil carefully.
Gently stir the beef back into the gravy and let the casserole rest for 5 minutes before serving.

Frequently Asked Questions

Absolutely. Cook on LOW for 7–8 hours or HIGH for 4–5 hours.
Can I add vegetables?
Yes. Carrots, mushrooms, onions, and peas all work well in this recipe.
Why is my gravy too thin?
Remove the foil during the last 15–20 minutes of baking to allow excess moisture to evaporate naturally.
