Oven baked 3-ingredient beef Lockwood is the kind of practical Midwestern potluck dish that earns a permanent place in a recipe box because it turns a short ingredient list into something deeply savory and crowd-pleasing. The magic is in slow oven time, which gives the beef a chance to become fork-tender while the simple sauce reduces into a rich glaze. It is an old-fashioned style of recipe—economical, unfussy, and dependable—which helps explain why dishes like this have stayed popular for decades.
Serve this beef over mashed potatoes, buttered egg noodles, or steamed rice to catch every bit of the sauce. For a potluck table, I like it alongside green beans, glazed carrots, a crisp cabbage slaw, or simple dinner rolls. If you are serving it for a cool-weather supper, a spoonful of the beef next to baked acorn squash or roasted root vegetables makes a particularly comforting plate.
Oven Baked 3-Ingredient Beef Lockwood
Servings: 6
Ingredients
2 pounds beef stew meat, cut into bite-size pieces
1 cup ketchup
1 packet dry onion soup mix
Directions
1. Preheat the oven to 325°F. Lightly grease a 9x13-inch glass baking dish.
2. Spread the beef pieces evenly in the baking dish.
3. In a small bowl, stir together the ketchup and dry onion soup mix until combined, then spoon the mixture over the beef and toss gently to coat.
4. Cover the dish tightly with foil and bake for 1 hour 30 minutes, stirring once halfway through.
5. Remove the foil, stir the beef, and continue baking for 20 to 30 minutes more, until the sauce is thickened and the beef is very tender.
6. Let the dish rest for 5 minutes before serving so the glaze settles over the beef.
Variations & Tips
Use the right cut: Stew meat works well, but if you have time to cube chuck roast yourself, you will usually get better marbling and more even tenderness after baking.
Keep it covered first: The covered portion of the baking time is what helps the beef soften. If the dish seems dry before the meat is tender, add a few tablespoons of water and cover it again.
Sweeter glaze option: If you like that classic potluck sweet-savory balance, stir 1 to 2 tablespoons of brown sugar into the sauce mixture. It will help the glaze caramelize a bit more around the edges.
Make it ahead: This dish reheats very well, which is one reason it has always fit potluck cooking so nicely. Bake it earlier in the day, cool slightly, and rewarm covered in a low oven before serving.
Stretch the sauce: For serving over noodles or rice, you can stir in 1/4 cup water before baking if you want a little more sauce without changing the character of the dish too much.
