This oven baked 3-ingredient hobo beef casserole is the kind of stick-to-your-ribs supper my uncle swore got him through more than one lean Midwestern winter. He learned it as a young man working long days, when money was tight but appetites were big. Just ground beef, potatoes, and beef broth come together in the oven to make a bubbling, hearty bake with golden slices of potato soaking up rich, dark juices and crumbled browned beef on top. It’s humble, filling, and wonderfully comforting—perfect for nights when you want real food without a lot of fuss.
Serve this casserole straight from the oven with something bright or crisp alongside to balance the richness—think a simple green salad with a tangy dressing, buttered green beans, or steamed peas. A slice of crusty bread or a warm dinner roll is handy for soaking up the savory broth that collects in the bottom of the dish. A jar of dill pickles or pickled beets on the table adds that old-fashioned farmhouse touch and a bit of zip to cut through the hearty beef and potatoes.
Oven Baked 3-Ingredient Hobo Beef Casserole
Servings: 4

Ingredients
1 1/2 pounds ground beef (80–85% lean)
2 pounds russet or Yukon Gold potatoes, peeled and thinly sliced
3 cups canned or boxed beef broth (low sodium if possible)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a medium ceramic casserole dish (about 2 to 2 1/2 quarts) with a bit of oil or a swipe of beef fat from the package if you like, just to keep the potatoes from sticking.
In a large skillet over medium-high heat, crumble the ground beef and cook, stirring often, until it is well browned and no pink remains, about 8–10 minutes. As it cooks, break it into small crumbles with a spoon so it will layer nicely over the potatoes.
Once the beef is browned, drain off most of the excess fat from the skillet, leaving just a light coating to carry the flavor. Set the cooked beef aside while you prepare the potatoes.
Peel the potatoes and slice them into thin rounds, about 1/8 to 1/4 inch thick. Try to keep the slices fairly even so they cook at the same rate and turn tender all the way through.
Arrange the sliced potatoes in the prepared casserole dish in overlapping layers, like shingles on a roof. Spread them out evenly so the whole bottom of the dish is covered and the layers are roughly level.
Sprinkle the browned ground beef evenly over the top of the potatoes, making sure to cover as much of the surface as you can with the crumbled meat.
Slowly pour the beef broth over the casserole, letting it seep down through the beef and potatoes. The broth should come up around the sides and almost cover the potatoes, but the very top layer of beef can sit slightly above the liquid so it browns nicely.
Cover the casserole dish tightly with a lid or a layer of aluminum foil, crimping the edges to hold in the steam. Place the dish on the middle rack of the preheated oven.
Bake the casserole covered for 45 minutes, allowing the potatoes to soften and start absorbing the broth. This covered time helps everything cook through without drying out.
After 45 minutes, carefully remove the lid or foil (watch for escaping steam). Return the uncovered casserole to the oven and bake for another 25–35 minutes, or until the potatoes are very tender when pierced with a fork, the broth has reduced to a rich, dark, bubbling sauce, and the beef on top is nicely browned.
Once done, remove the casserole from the oven and let it rest for about 10 minutes before serving. This short rest allows the bubbling broth to settle and thicken slightly so each spoonful holds together and you get some of everything—tender potatoes, browned beef, and savory juices—in every serving.
Variations & Tips
For a bit of extra comfort without adding more ingredients, you can lightly season the beef with just salt and black pepper while browning, if you keep those as pantry staples. If you’re feeding a crowd with heartier appetites, stretch the casserole by serving it over buttered egg noodles or with an extra boiled potato on the side. To make cleanup easier, line the bottom rack of your oven with a sheet of foil in case the broth bubbles over. If you prefer a slightly thicker, less brothy casserole, reduce the beef broth to 2 1/2 cups or bake uncovered a little longer at the end until the liquid cooks down to your liking. For a deeper roasted flavor, you can par-brown the potato slices by tossing them in a hot dry skillet for a few minutes before layering, though it’s not necessary. Food safety tip: Always cook ground beef to an internal temperature of at least 160°F (71°C); browning it fully in the skillet before baking takes care of that. Be sure to refrigerate leftovers within 2 hours of baking, store them in a covered container, and reheat thoroughly until steaming hot before serving again.
