This 5-ingredient slow cooker hamburger casserole is my kind of weeknight cooking: practical, comforting, and built entirely from pantry and fridge staples. You brown a bit of ground beef, pour it into the slow cooker, scatter on dry pasta, then smother everything with a creamy, tomato-kissed sauce and a blanket of cheese. It has the spirit of a Midwestern hamburger hotdish—simple, hearty, and family-friendly—but streamlined for the slow cooker so you can walk away and let it do the work. If your household loves cheeseburgers and pasta, this is the kind of meal that quietly slips into the regular rotation.
Serve this casserole straight from the slow cooker with a simple green salad or steamed green beans to balance the richness. Garlic bread or warm dinner rolls are great for catching any extra sauce. A tangy side—like dill pickles or a quick cucumber salad—echoes classic burger flavors and keeps the meal from feeling too heavy. For adults, a light red wine or a crisp lager pairs nicely with the beef and cheese, while milk or sparkling water with lemon works well for kids.
5-Ingredient Slow Cooker Hamburger CasseroleServings: 6
Ingredients
1 1/2 pounds ground beef (80–90% lean)
2 cups beef broth
1 can (10.5 ounces) condensed cream of mushroom soup
2 cups dry short pasta (such as rotini, penne, or small shells)
2 cups shredded cheddar cheese, divided
1 teaspoon kosher salt (optional, to taste)
1/2 teaspoon black pepper (optional, to taste)
Nonstick cooking spray or 1 teaspoon neutral oil for the slow cooker insert (optional)
Directions
Lightly coat the inside of your slow cooker with nonstick cooking spray or a thin film of neutral oil to help prevent sticking and make cleanup easier.
In a large skillet over medium-high heat, add the ground beef. Cook, breaking it up with a spoon, until fully browned and no pink remains, about 6–8 minutes. If there is a lot of grease, drain off most of the fat, leaving just a tablespoon or so for flavor.
Season the browned beef lightly with salt and black pepper, if using, then pour the beef evenly into the bottom of the slow cooker, spreading it into a level layer. This should resemble a thick, meaty base in the bottom of the pot.
Sprinkle the dry pasta evenly over the browned beef in the slow cooker. Do not stir; you want the beef on the bottom and the pasta just above it so everything cooks evenly.
In a medium bowl, whisk together the beef broth and condensed cream of mushroom soup until you have a smooth, creamy, pourable sauce. This will look thick but still fluid enough to drizzle.
Pour the creamy sauce mixture evenly over the dry pasta and beef, making sure all the pasta is moistened. Gently press down any exposed pasta so it is mostly submerged in the liquid and sauce, but do not stir the layers together.
Cover the slow cooker with the lid and cook on HIGH for 2–3 hours or on LOW for 4–5 hours, or until the pasta is tender and most of the liquid has been absorbed into a thick, creamy sauce. Avoid lifting the lid frequently, as heat loss can lengthen cooking time.
Once the pasta is tender, sprinkle 1 1/2 cups of the shredded cheddar cheese evenly over the top of the casserole. Cover and cook on HIGH for an additional 10–15 minutes, just until the cheese is fully melted and bubbly.
Turn off the slow cooker. If you like a cheesier top, sprinkle the remaining 1/2 cup cheddar over the hot casserole and let it sit, covered, for 5 minutes to melt from the residual heat.
Serve the casserole straight from the slow cooker, scooping down through the cheesy top to get layers of beef, pasta, and creamy sauce in each portion. Taste and adjust seasoning at the table if needed.
Variations & Tips
You can easily adapt this basic formula without losing the spirit of the recipe. For a slightly lighter version, use 90–93% lean ground beef and reduced-sodium beef broth, and consider a lower-sodium condensed soup to keep the salt in check. If your family prefers a more pronounced tomato note, replace 1/2 cup of the beef broth with tomato sauce or add a few tablespoons of ketchup to the creamy mixture—this leans into a cheeseburger casserole flavor. For extra creaminess, swap cheddar for a blend like Colby-Jack or Monterey Jack, or finish with a spoonful of sour cream stirred gently into the pasta just before adding the cheese topping (do this off heat to prevent curdling). To sneak in vegetables without changing the 5-core-ingredient structure, you can stir in 1–2 cups of thawed frozen peas, corn, or mixed vegetables during the last 30 minutes of cooking; just make sure the pasta is nearly tender first so the added moisture doesn’t dilute the sauce too much. If you want more seasoning depth, a teaspoon of garlic powder, onion powder, or dried Italian seasoning can be mixed with the beef as it browns. Food safety notes: always brown ground beef thoroughly until no pink remains and the juices run clear; the internal temperature should reach 160°F (71°C). Drain excess fat to reduce grease in the finished dish and minimize splattering while cooking. Avoid leaving the cooked casserole at room temperature for more than 2 hours (or 1 hour if your kitchen is very warm); refrigerate leftovers promptly in shallow containers. Reheat leftovers to at least 165°F (74°C) before serving, adding a splash of broth or water if the pasta has absorbed too much sauce. If using a programmable slow cooker, do not start the recipe with raw ground beef in the insert on a delayed timer—meat should not sit at room temperature or in the “danger zone” (40–140°F) for an extended period before cooking.
