How to Make Slow Cooker Cowboy Casserole Recipe
Step 1: Brown the Beef and Aromatics
Start by heating the olive oil or butter in a large skillet over medium-high heat. Add the ground beef and cook it, breaking it up with a spoon until it’s no longer pink. Toss in the diced onion and minced garlic, cooking for 3 to 4 minutes until the onion softens and any moisture evaporates. Season lightly with salt and pepper, then remove the skillet from heat. This step builds the hearty, savory foundation of the cowboy casserole.
Step 2: Mix the Sauce Base
In a large mixing bowl, combine the diced tomatoes, tomatoes with green chilies, pinto beans, corn, beef broth, tomato sauce, chili powder, smoked paprika, ground cumin, dried oregano, salt, black pepper, and Worcestershire sauce. Stir everything together until well mixed—this flavorful sauce is the magic glue that holds the Slow Cooker Cowboy Casserole Recipe together.
Step 3: Prep the Slow Cooker
Lightly grease the inside of your 6-quart slow cooker with cooking spray or a thin coating of oil. This prevents sticking and makes clean-up a breeze—an essential step for smooth slow cooker success.
Step 4: Layer Potatoes and Beef
Create the layers starting with a bed of thinly sliced potatoes at the bottom of the slow cooker, slightly overlapping to cover the base evenly. Spoon a portion of the browned beef and onion mixture over the potatoes, then pour some of the tomato-bean sauce on top. Repeat layering potatoes, beef, and sauce until all your ingredients are used, making sure to finish with a layer of sauce on top. This layering helps keep the potatoes tender and ensures every bite is bursting with flavor.
Step 5: Slow Cook Until Tender
Cover the slow cooker and cook on LOW for 7 to 8 hours or on HIGH for 4 to 5 hours. You’re aiming for fork-tender potatoes and a bubbling, inviting casserole. Avoid the temptation to lift the lid too often since that releases heat and can extend the cooking time.
Step 6: Add the Cheese Topping
Once the potatoes are perfectly tender, sprinkle the shredded cheddar cheese evenly over the casserole’s surface. Cover again and let it cook for another 10 to 15 minutes until the cheese is melted, gooey, and utterly irresistible. If you’re not ready to serve right away, switch your slow cooker to the WARM setting to keep everything cozy and melty.
Step 7: Garnish and Serve
Scoop generous portions of the slow cooker cowboy casserole into bowls or onto plates. Sprinkle chopped fresh parsley or sliced green onions for a burst of freshness. Feel free to add your favorite toppings like sour cream, jalapeños, or extra cheese to personalize your experience.

This cowboy casserole stands on its own but pairs wonderfully with a crisp green salad or steamed veggies to balance the meal. Cornbread or warm dinner rolls also make great companions, perfect for soaking up every last bit of that amazing sauce.

FAQs
Can I use other types of ground meat?
Absolutely! While ground beef is classic, ground turkey, chicken, or even sausage can work well if you want a different twist or a lighter version.

You can try sweet potatoes for a sweeter, earthier flavor or even thinly sliced vegetables like zucchini, but keep in mind the cooking times might vary slightly.
Is it possible to make this recipe vegetarian?
Yes, simply skip the ground beef and add extra beans or lentils for protein. You might want to use vegetable broth instead of beef broth for the sauce.
Can I double the recipe for a larger group?
Yes! Just make sure your slow cooker is large enough to accommodate the extra ingredients, or divide the recipe between two slow cookers if needed.
How spicy is this casserole? Can I adjust the heat?
This Slow Cooker Cowboy Casserole Recipe has a mild to moderate kick thanks to the chili powder and tomatoes with green chilies. You can easily adjust the heat by adding more chili powder, fresh jalapeños, or hot sauce, or keep it milder by reducing those ingredients.

Instructions
- Brown the beef and aromatics: In a large skillet, heat the olive oil or butter over medium-high heat. Add the ground beef and cook, breaking it up with a spoon, until no longer pink.

- Prep the slow cooker: Lightly grease the inside of a 6-quart slow cooker with cooking spray or a thin layer of oil to prevent sticking.
- Layer potatoes and beef: Arrange a layer of thinly sliced potatoes over the bottom of the slow cooker, slightly overlapping them. Spoon a portion of the browned beef mixture over the potatoes, then pour some of the tomato-bean sauce over the top.
