Oven Baked 4-Ingredient Beef Wellesley
Servings: 6
Ingredients
2 pounds beef stew meat
Directions
1. Preheat the oven to 325°F and lightly grease a medium casserole dish or Dutch oven.
2. Place the beef stew meat in the dish, then add the dry onion soup mix, cream of mushroom soup, and beef broth.
3. Stir everything together until the beef is evenly coated and the sauce is well combined.
4. Cover tightly with a lid or foil and bake for 2 to 2 1/2 hours, stirring once halfway through, until the beef is very tender.
5. Remove from the oven, let it rest for 5 to 10 minutes, then spoon over mashed potatoes, noodles, or rice and serve warm.
Variations & Tips
Make It Mushroomier: If your family loves a deeper mushroom flavor, add a handful of sliced mushrooms to the dish before baking. They cook down into the gravy and make the finished casserole feel even heartier.
For a Thicker Gravy: If you like a more spoon-coating sauce, uncover the dish for the last 20 minutes of baking so the gravy can reduce a bit. Letting it rest before serving also helps the sauce thicken naturally.
Best Cut Tip: Stew meat works well for convenience, but chuck roast cut into chunks usually gives the most tender result after a long bake. If your beef seems lean, an extra splash of broth can help keep everything nice and saucy.
Make-Ahead Option: You can assemble everything the night before, cover, and refrigerate it until the next day. This is one of those great busy-week recipes where a few minutes of prep earlier makes dinner feel a lot easier later on.
