This slow cooker cowboy casserole layers potatoes, ground beef, beans, and corn in the crockpot and finishes with a creamy, cheesy sauce. It’s a hearty, hands-off dinner that’s ready in 4 hours with no oven required!
An Easy Cowboy Casserole Done in the Crockpot!
Okaaaaaaay, let’s talk about this crockpot cowboy casserole, which is TRUE hearty comfort food without turning on the oven or hovering over the stove. It layers seasoned ground beef with tender potatoes, beans, and corn; then finishes everything off at the end with a creamy, cheesy sauce that pulls the whole thing together. It’s the kind of cozy, set-it-and-forget-it dinner that fills up even the hungriest crew at my table, and I’m telling you, your family is going to go bananas for it!
What sets this version apart is definitely the real potatoes and the ground beef. Most cowboy casseroles go the tater tot route, which is fine, but I use Yukon golds or red potatoes that turn meltingly tender right in the slow cooker, soaking up all that savory, smoky sauce. It’s kind of like a cross between scalloped potatoes and chili, in the BEST possible way. I also opted to use ground beef instead of sausage, because who doesn’t love a slow cooker recipe with ground beef? Easy, budget friendly, and family approved!
In testing I learned that you need to stir the sour cream and cheddar in at the very end rather than letting them cook for hours, because that’s what keeps the sauce creamy instead of grainy or separated. And if you love this ground-beef-and-potato combo, my ground beef and potatoes is another hearty, budget-friendly dinner worth keeping on rotation! Or, when you’re craving more easy crockpot comfort, my crockpot beef taco casserole brings the same hands-off, family-friendly vibe with a Tex-Mex spin.

Robyn’s Testing Tips for Crockpot Cowboy Casserole with Meat and Potatoes
- I like to stick with lean ground beef and drain it well after browning. There’s already plenty of richness from the cheese and sour cream, so draining the fat keeps things hearty without going greasy at the bottom.
- This one takes swaps nicely if you want to switch it up! Ground turkey or chicken work in place of the beef, and pinto or black beans slide right in if kidney beans aren’t your thing.
- Leftovers keep in the fridge for up to four days and reheat well. The potatoes drink up the sauce as they sit, so I add a splash of broth when warming a bowl back up to loosen everything if necessary.
Cowboy Casserole (Crockpot)
Ingredients
- 1 teaspoon olive oil
- 1 pound lean ground beef
- 1 small yellow onion, diced
- 1 ¼ teaspoons kosher salt, divided
- 3 cloves garlic, minced
- ½ cup low-sodium beef broth
- 2 tablespoons tomato paste
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon smoked paprika
- ¼ teaspoon black pepper
- 1 ½ pounds Yukon Gold or red potatoes, sliced ¼-inch thick
- 1 (15-ounce) can kidney beans, drained and rinsed
- 1 (15-ounce) can corn, drained (or 1½ cups frozen corn, thawed)
To Add at the End
- ¾ cup sour cream
- 1 ½ cups shredded sharp cheddar cheese, divided
- 2 tablespoons Mexican hot sauce (such as Cholula) optional, to taste)
Equipment
Instructions
- Cook the Beef: Heat a large skillet over medium-high heat. Add the olive oil, ground beef, onion, and ¼ teaspoon of the salt. Break the beef into crumbles and cook until no pink remains and the onion is softened, about 5-6 minutes.
- Add the garlic and cook for 1 minute more until fragrant. Drain any excess fat.
- Make the Sauce: In a medium bowl, whisk together the beef broth, tomato paste, Worcestershire sauce, garlic powder, onion powder, smoked paprika, black pepper, and 1 teaspoon of salt until smooth.
- Assemble: Layer the sliced potatoes in the bottom of a 6-quart slow cooker. Scatter the kidney beans and corn evenly over the potatoes. Add the browned beef mixture on top. Pour the sauce evenly over everything and stir gently to combine.
- Cook: Cover and cook on high for 2-4 hours, or low for 4-6 hours, until the potatoes are completely tender when pierced with a fork.
- Finish: In a small bowl, stir together the sour cream, 1 cup of the cheddar, and the hot sauce (if using) until combined. Gently stir the mixture into the beef potato mixture until evenly incorporated, being careful not to break up the potatoes too much.
- Sprinkle the remaining ½ cup of cheddar over the top, cover, and let melt on high for 5 to 10 minutes. Taste for seasoning and adjust with salt and pepper as needed.
Notes
- Slicing the potatoes to a consistent ¼-inch thickness is key, as uneven slices mean some will be tender while others are still firm.
- Stirring the sour cream and cheddar in at the very end rather than cooking them in prevents separation and keeps the sauce creamy.
