- In a skillet, brown the ground beef over medium heat and drain any excess fat.
- Layer the ingredients in the slow cooker starting with the sliced potatoes.
- Next, add the browned beef, chopped onion, garlic, beans, corn, and diced tomatoes (don’t forget the juice!).
- In a bowl, mix the cream of mushroom soup, milk, chili powder, salt, and pepper. Pour this mixture over the layers in the slow cooker.
- Cook on low for 6-8 hours.
- About 15 minutes before serving, sprinkle the shredded cheese on top, cover, and let it melt.
Best ways to enjoy it
Serve this cowboy casserole hot, either straight from the slow cooker or transferred to a warm dish. Pair it with a simple side salad or some crusty bread to soak up all those flavors. For a twist, why not add a dollop of sour cream or a sprinkle of fresh chives? This meal also shines when served with a refreshing cucumber salad or sweet cornbread on the side.
Storage and reheating tips
Got leftovers? No problem! Allow the casserole to cool before storing it in an airtight container in the refrigerator. It’s best enjoyed within 3-4 days. When reheating, make sure to heat it thoroughly to 165°F to ensure food safety. You can also freeze individual portions for up to 3 months; just defrost in the refrigerator overnight before reheating.
Helpful cooking tips
- For extra flavor, consider adding a bit of Worcestershire sauce or hot sauce to your beef while browning it.
- If you’re worried about texture, slice your potatoes a little thicker to avoid them becoming too mushy during the slow cook time.
- Consider using sweet potatoes for a slightly different taste and added nutrition.
Creative twists
Feeling adventurous? Try substituting ground turkey or even a plant-based meat alternative for a lighter take. You could also incorporate different vegetables, such as bell peppers or zucchini, for added color and nutrition. If you want more heat, swap in some jalapeños or add extra chili powder. Don’t hesitate to get creative with the cheese, using pepper jack or mozzarella for a different flavor.
Common questions
- How long does it take to prepare? Prep time is roughly 15-20 minutes, and cooking is 6-8 hours on low in the slow cooker.
- Can I make this dish ahead of time? Absolutely! You can prep all the ingredients the night before and store them in the slow cooker insert in the fridge. Just pop it in the cooker the next morning.
- Is it safe to freeze? Yes! Just make sure to let it cool completely before freezing in an airtight container.
- What if I don’t have certain ingredients? You can definitely substitute with what you have on hand. For example, use cream of chicken soup instead of mushroom, or add in any fresh or frozen veggies you have available.
