When you need dinner to stick to your ribs without emptying your wallet, Cowboy Casserole gets the job done. It’s a no-fuss meat, potatoes, beans, and tomato supper that works in either the crockpot for an easy hands-off meal or the pressure cooker when you need dinner on the table fast.
Place the onions on the bottom, layer the ground meat and sliced potatoes. You can use whatever kind of tomatoes you like, we used Italian seasoned diced tomatoes, because that's what we had on hand! Mix in 2 tablespoons of flour into the tomatoes, then pour it over the top. Set the pressure cooker for 12- 15 minutes. Seal and cook. Let it release naturally for about 5 minutes before manually releasing the pressure.
The combination is simple, filling, and practical. Serve it as-is for a hearty one-dish dinner, or reheat leftovers the next morning with a fried egg on top if you want breakfast to pull its weight too.

How to Make Cowboy Casserole
You can make this two ways, depending on whether you want convenience or speed.
Crockpot Directions
- Dice the onion, wash and slice the potatoes, and brown the ground chuck or turkey with 1 teaspoon salt, 1/2 teaspoon pepper, and 1 teaspoon garlic powder. Drain well.
- Layer the diced onion in the bottom of the crockpot.
- Add the browned meat, then layer on the sliced potatoes and drained red beans.
- Mix the diced tomatoes with 2 tablespoons flour, or use 1 can of tomato soup instead, then spread it over the top.
- Season with additional salt, pepper, and garlic to taste.
- Cover and cook on LOW for 7 to 9 hours, until the potatoes are tender.
Digital Pressure Cooker Directions
- Place the diced onions in the bottom of the pressure cooker.
- Layer the browned, seasoned meat over the onions, then add the sliced potatoes.
- Stir 2 tablespoons flour into the diced tomatoes, then pour the mixture over the top.
- Seal the cooker and set it for 12 to 15 minutes.
- Let the pressure release naturally for about 5 minutes, then manually release the remaining pressure before serving.
Tips for Best Results
Slice the potatoes evenly. That’s the difference between tender layers and random crunchy bits nobody asked for. Aim for thin, consistent slices so they cook at the same rate.
Drain the browned meat well. Too much grease can make the finished casserole heavy instead of hearty.
Don’t skip rinsing the beans. It improves the flavor and keeps the dish from tasting like canned bean liquid.
Use the tomato option that fits what’s in your pantry. Diced tomatoes with flour give you a chunkier finish, while tomato soup makes the sauce smoother and a little richer.
Easy Variations
- Swap the meat: Ground turkey works in place of ground chuck if you want a leaner version.
- Change the beans: Pinto beans or kidney beans will fit the same cowboy-style flavor profile if that’s what you have.
- Use seasoned tomatoes: Italian-style diced tomatoes work well here and add flavor without extra fuss.
- Top it at the table: A spoonful of sour cream, shredded cheese, or chopped green onions can dress it up fast if you want more of a loaded-baked-potato feel.
Storage and Reheating
Store leftovers in a shallow airtight container in the refrigerator for up to 4 days. For longer storage, freeze portions for up to 3 months. Those time frames are based on general leftover safety guidance from the USDA Food Safety and Inspection Service.
Reheat individual portions in the microwave until hot throughout, or warm larger portions in a covered baking dish in the oven. If you cooked it in the slow cooker, move leftovers to the refrigerator promptly rather than letting the crock sit around on the counter pretending it’s helping.
Serving Suggestions
This casserole is filling enough to stand on its own, but it also works well with a simple green salad, buttered bread, or cooked vegetables on the side.
Leftovers reheat well for lunch, and they’re especially good the next morning topped with a fried egg, just as suggested. If you like practical, savory meals that stretch well, take a look at Pork Chops with Creamy Scalloped Potatoes too.

Frequently Asked Questions about Cowboy Casserole
You can, and it works just fine. Ground turkey gives you a lighter casserole, but because it’s leaner, make sure you brown it well and season it fully so the finished dish doesn’t taste flat or watery.
Yes, brown it first. That step adds flavor, lets you drain off excess fat, and keeps the casserole from turning greasy after several hours of slow cooking.
Medium russet potatoes are a solid choice because they soften well and help thicken the casserole a bit as they cook. If you use waxier potatoes, they’ll hold their shape better but the dish may stay a little looser.
That small amount of flour helps thicken the tomato juices into more of a sauce instead of a thin broth. It’s a simple pantry fix that helps the casserole hold together better when you scoop it out.
Absolutely. Tomato soup gives you a smoother, more uniform sauce, while diced tomatoes make the casserole chunkier and a little less rich. Use whichever one fits your pantry and the texture you want.
Slice them evenly and keep the cooker on LOW for the full 7 to 9 hours. Thick, uneven potato slices are the usual culprit when part of the casserole is tender and part still chews like a bad decision.
Yes, freeze it in meal-size portions for up to 3 months. The potatoes may soften a bit more after thawing, but the casserole still reheats well for an easy lunch or backup dinner.
Plan on 6 servings for a practical family dinner. The original yield is given as 4 to 6 servings, and using 6 keeps the portions realistic if you’re serving it with bread, salad, or a vegetable on the side.
Keep it simple with a green salad, buttered bread, or a plain vegetable. The casserole already covers meat, starch, and beans, so the best side is usually something fresh or crisp to balance all that comfort food weight.
You can, and it’s a smart use of leftovers. Warm a portion until it’s hot throughout, then top it with a fried egg if you want the same hearty breakfast idea mentioned in the recipe.
