Ingredients You’ll Need

Here’s a detailed list of everything required to make this casserole. These measurements serve 6–8 people.

Main Ingredients

• 1 ½ pounds ground beef (80/20 recommended)
• 1 small yellow onion, finely chopped
• 3 cloves garlic, minced
• 6 medium russet potatoes, peeled and sliced into ¼-inch rounds
• 1 can (10.5 oz) cream of mushroom soup (or cream of cheddar)
• 1 cup sour cream
• 1 ½ cups shredded cheddar cheese (divided)
• 1 cup shredded Monterey Jack cheese
• 1 teaspoon smoked paprika
• 1 teaspoon salt
• ½ teaspoon black pepper
• 8 slices cooked bacon, crumbled
• 2 tablespoons chopped chives or green onions (optional garnish)
• Nonstick cooking spray or butter (for greasing the slow cooker)

Step-by-Step Instructions

Step 1: Brown the Ground Beef

Start by heating a large skillet over medium heat. Add the ground beef and cook until browned, about 6–8 minutes. Drain any excess fat.

Next, add the chopped onion and garlic. Sauté for another 3–4 minutes until the onion turns translucent and fragrant. Season the mixture with salt, pepper, and smoked paprika. Remove from heat and set aside.

Step 2: Prepare the Potatoes

While the beef cooks, peel and slice the potatoes. Aim for consistent thickness (around ¼ inch) to ensure even cooking. A mandoline slicer can help save time and improve uniformity.

Step 3: Mix the Sauce

In a mixing bowl, combine the cream of mushroom soup, sour cream, and 1 cup of cheddar cheese. Stir until well blended. This creamy mixture will bind all the ingredients together and add richness to every bite.

Step 4: Layer the Ingredients in the Slow Cooker

Lightly grease the bottom and sides of your slow cooker with nonstick spray or butter. Now it’s time to build the layers:

1. First Layer: Spread a third of the sliced potatoes on the bottom.
2. Second Layer: Spoon a third of the beef mixture over the potatoes.
3. Third Layer: Add a few dollops of the creamy cheese mixture, spreading gently.
4. Repeat the layers two more times in the same order.
5. Sprinkle the top with the remaining cheddar and all the Monterey Jack cheese.

Step 5: Cook on Low and Let It Simmer

Cover the slow cooker with its lid. Cook the casserole on LOW for 6–7 hours or until the potatoes are fork-tender. Avoid lifting the lid too often, as it releases heat and increases cook time.

Step 6: Add Bacon and Finish with a Garnish

About 15 minutes before serving, sprinkle crumbled cooked bacon on top and let it warm through. When ready, garnish with fresh chives or green onions for color and freshness.

Helpful Tips for Perfecting Cowboy Potato Casserole

Making this dish is easy, but a few expert tips can take it to the next level:

• Use Waxy Potatoes: While russet potatoes are common, Yukon Golds hold their shape better during long cook times.
• Drain Fat Thoroughly: Excess grease from beef can make the casserole oily. Take the time to drain it well after browning.
• Even Slicing Matters: Thinner slices cook faster. Use a mandoline or a sharp knife for uniform pieces.
• Cheese Melting Tip: For a smoother melt, shred your own cheese instead of using pre-shredded varieties coated with anti-caking agents.

Variations to Try

Want to switch things up? This dish is highly adaptable.

1. Add Vegetables

Include layers of diced bell peppers, corn, or peas for extra nutrition and color.

2. Try Different Meats

Substitute ground beef with ground turkey, sausage, or even chopped rotisserie chicken for a lighter or different flavor profile.

3. Spice It Up

Add a dash of cayenne or chopped jalapeños if you like your meals with a kick.

4. Go Vegetarian

Swap the meat for black beans and use cream of celery soup for a delicious meat-free version.

5. Tex-Mex Twist

Use taco-seasoned beef and add drained canned tomatoes and green chiles. Top with crushed tortilla chips before serving for a crispy contrast.

Conservation and Storage

This casserole stores and reheats wonderfully, making it ideal for meal prep.

Refrigerator

Store leftovers in an airtight container for up to 4 days. Reheat individual servings in the microwave for 2–3 minutes or until heated through.

Freezer

To freeze, allow the casserole to cool completely. Transfer to a freezer-safe container or wrap in plastic wrap and aluminum foil. Freeze for up to 3 months.

Reheating from Frozen

Thaw overnight in the refrigerator. Reheat in a 350°F oven for about 25–30 minutes or until hot in the center. You can also reheat in the microwave, though texture may be slightly softer.

Serving Suggestions

Pair this hearty dish with lighter sides to balance the richness.

• Fresh Green Salad: A simple vinaigrette offsets the creamy casserole perfectly.
• Steamed Broccoli or Green Beans: Adds a healthy, vibrant touch.
• Dinner Rolls or Cornbread: Great for soaking up the cheesy sauce.
• Pickles or Coleslaw: For a tangy contrast that refreshes the palate.

For drinks, consider sweet iced tea, sparkling lemonade, or even a bold red wine like Zinfandel for adults.

Frequently Asked Questions

Can I cook this on high instead of low?

Yes, you can cook it on HIGH for 3–4 hours, but the texture of the potatoes may be slightly firmer. Low and slow delivers better results.

Can I make this casserole ahead of time?

Absolutely! You can assemble all layers the night before and refrigerate the insert. In the morning, place it into the slow cooker base and start cooking.

Can I use frozen potatoes?

Frozen diced or hash brown-style potatoes can work in a pinch. Just note they may release water and affect consistency, so reduce other liquid ingredients slightly.

Is it gluten-free?

It can be! Use gluten-free cream of mushroom soup and verify that other ingredients (like bacon or cheese) are certified gluten-free.

Can I double the recipe?

If you have a large-capacity (7–8 quart) slow cooker, you can double the recipe. Extend the cook time by 1–2 hours and make sure not to overfill past the two-thirds mark.
