Ingredients

• 1½ pounds ground beef
• 2 pounds russet potatoes, peeled and thinly sliced
• 1 small yellow onion, diced
• 1 can (10.5 ounces) condensed cream of mushroom soup
• 1½ cups shredded cheddar cheese
• ½ cup beef broth
• 1 teaspoon garlic powder
• 1 teaspoon smoked paprika
• ½ teaspoon black pepper
• ½ teaspoon salt

How to Make Slow Cooker Cowboy Potato Casserole

1. Brown the Beef

Heat a large skillet over medium-high heat. Add the ground beef and diced onion.

Cook until the beef is browned and the onion is softened, breaking the meat into small pieces as it cooks. Drain excess grease if needed.

2. Prepare the Potatoes

Peel the potatoes and slice them thinly and evenly. Keeping the slices similar in thickness helps them cook at the same rate.

3. Mix the Sauce

In a bowl, whisk together the cream of mushroom soup, beef broth, garlic powder, smoked paprika, black pepper, and salt until smooth.

4. Layer the Casserole

Lightly grease the slow cooker.

Add a layer of sliced potatoes, followed by some of the browned beef and onion mixture. Continue layering until everything has been added.

Pour the creamy soup mixture evenly over the top.

5. Slow Cook

Cover and cook on LOW for 5–7 hours, or until the potatoes are tender and the casserole is bubbling around the edges.

Cooking time can vary depending on the thickness of the potato slices and your slow cooker.

6. Add the Cheese

About 20–30 minutes before serving, sprinkle the shredded cheddar cheese evenly over the casserole.

Cover and continue cooking until the cheese is completely melted.

7. Serve

Let the casserole sit uncovered for about 5–10 minutes before serving. Spoon generous portions onto plates while warm.

Tips for the Best Cowboy Potato Casserole

Slice the potatoes thinly and evenly so they cook properly. Very thick slices may remain firm after the recommended cooking time.

For the best texture, avoid lifting the slow cooker lid repeatedly during cooking.

You can use lean ground beef to reduce excess grease, or drain the beef thoroughly after browning.

For an extra golden cheese topping, transfer the finished casserole to an oven-safe dish and place it under the broiler for a few minutes, watching carefully.

Easy Variations

• Bacon: Stir cooked, crumbled bacon into the beef mixture.
• Spicy: Add diced jalapeños or a pinch of chili powder.
• Extra cheesy: Use a combination of cheddar and Monterey Jack.
• Corn: Add a cup of drained canned corn for a slightly sweet contrast.
• Beans: Add drained pinto or ranch-style beans for an even heartier casserole.

What to Serve With Cowboy Potato Casserole

This casserole is filling enough to serve as a complete meal, but it also pairs well with green beans, steamed broccoli, corn on the cob, or a crisp green salad.

A simple dinner roll or slice of crusty bread is also perfect for scooping up the creamy sauce.

How to Store Leftovers

Store leftover casserole in an airtight container in the refrigerator for 3–4 days.

Reheat individual portions in the microwave until heated through. For larger portions, use a covered oven-safe dish at 350°F until warmed.

You can also freeze portions in freezer-safe containers for up to 2–3 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I use ground turkey instead of beef?

Yes. Ground turkey can be substituted for ground beef, although the flavor will be slightly lighter.

Can I use different potatoes?

Yes. Yukon Gold potatoes work especially well because they have a creamy texture. Russet potatoes are also a good choice.

Can I assemble this casserole ahead of time?

Yes. You can brown the beef and prepare the potatoes and sauce ahead of time. Refrigerate the prepared components separately until you’re ready to assemble and cook.

Can I make this without cream of mushroom soup?

You can substitute condensed cream of chicken soup or another creamy condensed soup. The flavor will change slightly but the casserole will remain rich and creamy.
