I used Cream of Mushroom w/ Roasted Garlic.
Add the cubed beef to a 13x9 baking dish.
Combine the cream of mushroom soup, onion soup mix, brown gravy mix and water. Add the mushrooms and stir to combine. Pour over the beef and stir to mix thoroughly.
Cover with foil and bake at 300° for three hours. Uncover and serve on top egg noodles.
