Ingredients Notes

This Slow Cooker Cowboy Casserole comes together with simple, wholesome ingredients that you probably already have in your kitchen. Each one plays a key role in creating the rich, hearty flavors that make this dish so irresistible.

Ground Beef – The base of the casserole, giving it a rich, meaty flavor. You can also use ground turkey or ground sausage for a different twist.
Potatoes – I recommend using Russet or Yukon Gold potatoes, as they hold up well during slow cooking and absorb all the delicious flavors. If you prefer, frozen hash browns can be a great shortcut.
Bacon – Adds a smoky, crispy bite that enhances the overall flavor. You can use pre-cooked bacon for convenience.
Cream of Mushroom Soup – This creamy base gives the casserole a thick, velvety texture. If you’re not a fan, swap it with cream of cheddar or cream of chicken soup for a different flavor profile.
Canned Diced Tomatoes & Green Chiles – Adds a touch of zest and mild spice, balancing the richness of the casserole. If you prefer it milder, use plain diced tomatoes.
Corn & Beans – A mix of sweet corn and kidney beans adds texture, heartiness, and a little southwestern flair.
Cheese – Shredded cheddar cheese melts into the casserole, creating a gooey, cheesy topping. Feel free to experiment with Monterey Jack or Pepper Jack for extra flavor.
Seasonings – A blend of garlic powder, onion powder, smoked paprika, and black pepper gives the dish its warm, savory depth.

Special Equipment

You'll need a slow cooker (4-6 quart size works best) and a skillet to brown the ground beef before adding it to the slow cooker.

How To Make This Slow Cooker Cowboy Casserole

Making Slow Cooker Cowboy Casserole is as simple as layering everything in your slow cooker and letting it do the work for you. Follow these easy steps:

Brown the Beef & Cook the Bacon
Start by browning the ground beef in a large skillet over medium heat. Drain any excess grease and set it aside. If you’re using raw bacon, cook it until crispy, then crumble it into small pieces.
Layer the Ingredients
In your slow cooker, start by adding a layer of sliced potatoes, followed by half the cooked beef, half the bacon, and half the canned ingredients (tomatoes, beans, and corn). Sprinkle a bit of seasoning over each layer. Repeat the layers once more.
Add the Creamy Base
Spread the cream of mushroom soup evenly over the top, ensuring it covers the ingredients below. This will melt down as it cooks, creating a rich, creamy texture.
Slow Cook to Perfection
Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours, until the potatoes are tender. About 30 minutes before serving, sprinkle the shredded cheese on top and let it melt into the casserole.
Serve & Enjoy
Once everything is hot and bubbly, scoop generous portions onto plates and garnish with fresh parsley or green onions for a pop of color. Serve with crusty bread or a simple green salad for a complete meal.

Storage Options

One of the best things about Slow Cooker Cowboy Casserole is that leftovers taste just as good (if not better!) the next day. Here’s how to store and reheat it:

Refrigeration: Store in an airtight container for up to 4 days. Reheat in the microwave or on the stovetop until warm.
Freezing: This casserole freezes beautifully! Store in a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating Tip: If reheating from frozen, add a splash of broth or milk to restore the creamy consistency.

Variations and Substitutions

This cowboy casserole is super adaptable, so feel free to customize it based on your preferences!

Make it Spicier – Add diced jalapeños, hot sauce, or swap cheddar for Pepper Jack cheese for a little extra kick.
Lighten it Up – Use ground turkey, swap the cream of mushroom soup for Greek yogurt, and reduce the cheese for a healthier version.
Vegetarian Version – Skip the beef and bacon, and use black beans, extra corn, and bell peppers for a delicious meat-free option.
Add More Veggies – Mushrooms, bell peppers, and zucchini all work well in this casserole, adding extra nutrients and flavor.
Use Different Cheeses – Try smoked gouda, Monterey Jack, or Colby Jack for a different cheesy twist.
