This oven-baked beef stew casserole is the kind of practical Midwestern supper that earns a regular place in the dinner rotation: a few pantry staples, one casserole dish, and a long, gentle bake that turns inexpensive stew meat tender without any stovetop browning. It borrows the comfort of classic beef stew but streamlines the method into a true dump-and-bake meal, making it especially useful on busy days when you want hearty results with very little hands-on work.
Serve it with mashed potatoes, buttered egg noodles, or crusty bread to catch the rich pan juices. A simple green salad, steamed green beans, or peas make good balancing sides, and if you want an extra-comforting plate, spoon the beef and carrots over hot rice or creamy polenta.
Oven Baked 4-Ingredient Beef Stew Casserole
Servings: 6
Ingredients
2 pounds raw beef stew meat
Directions
1. Preheat the oven to 325°F. Spread the raw beef stew meat in a single layer in a glass 9x13-inch casserole dish, then tuck the baby carrots around the beef so everything cooks as evenly as possible.
2. Spoon the cream of mushroom soup over the beef and carrots, then sprinkle the onion soup mix evenly across the top. Cover the dish tightly with foil to trap moisture during the long bake.
3. Bake for 2 1/2 to 3 hours, checking at the 2-hour mark. The beef is done when it shreds easily with a fork and the carrots are tender.
4. Remove the foil and stir once before serving so the pan juices coat the beef and carrots evenly. Serve hot.
Variations & Tips
For extra sauce: If you plan to serve this over mashed potatoes, noodles, or rice, add 1/2 cup water when you add the soup mixture. That little bit of extra liquid helps create more gravy as the casserole bakes.
For the most tender beef: Stew meat can vary from package to package, so start checking at 2 hours but expect that some batches need the full 3 hours. If the beef still seems firm, cover it back up and keep baking until it pulls apart easily.
Pan setup tip: A tight foil seal matters here because this recipe relies on trapped moisture rather than browning. Press the foil firmly around the edges of the glass dish so the meat gently braises instead of drying out.
Add a vegetable side later: Because this is a true 4-ingredient casserole, keep the baking dish simple and serve extra vegetables on the side instead of adding them to the pan. Green beans, peas, or broccoli work especially well.
