This oven baked 3-ingredient beef stew meat is one of those dependable old-fashioned dishes that turns a simple package of stew beef into something rich, tender, and deeply comforting. It is the kind of recipe busy families have passed around for years because it uses pantry staples, takes very little hands-on work, and comes out of the oven with a glossy savory glaze that feels special enough for Sunday dinner.
Serve this beef over mashed potatoes, buttered egg noodles, or fluffy white rice so nothing goes to waste when that sauce settles onto the plate. A side of green beans, roasted carrots, or a crisp salad balances the richness nicely, and warm dinner rolls are always welcome for scooping up every last bit from the baking dish.
Oven Baked 3-Ingredient Beef Stew Meat
Servings: 6
Ingredients
2 pounds beef stew meat
1 packet dry onion soup mix, about 1 ounce
1 can condensed cream of mushroom soup, 10.5 ounces
Directions
1. Preheat your oven to 325°F. Lightly grease a 9x13-inch glass baking dish or another oven-safe casserole dish.
2. Add the beef stew meat to the baking dish. Spoon the cream of mushroom soup over the top, then sprinkle the dry onion soup mix evenly over everything.
3. Stir everything together until the beef is well coated. Cover the dish tightly with foil.
4. Bake for 2 1/2 to 3 hours, stirring once or twice during cooking, until the beef is very tender and the sauce has darkened into a rich savory glaze.
5. Let the dish rest for 5 minutes before serving, then spoon the beef and sauce over mashed potatoes, noodles, or rice.
Variations & Tips
For extra moisture: If you like a little more sauce for serving over potatoes or rice, stir in 1/2 cup water or beef broth before baking. The finished dish will be a bit looser but still full of flavor.
For picky eaters: If someone in the family is unsure about mushroom soup, this dish still bakes up mild and savory. Serving it over buttery noodles can make it feel more familiar and easier for kids to enjoy.
For deeper flavor: Brown the stew meat in a skillet with a little oil before adding it to the baking dish. This is optional, but it adds a richer beefy taste and a darker finished glaze.
Make-ahead tip: You can assemble the dish a few hours ahead, cover it, and refrigerate it until baking time. If it goes into the oven cold from the refrigerator, add about 10 to 15 minutes to the cooking time.
Storage tip: Leftovers keep well in the refrigerator for up to 3 days and reheat beautifully. Warm them gently, covered, in the oven or microwave so the beef stays tender.
