How to Make Slow Cooker Cowboy Casserole
1. Brown the Ground Beef
Heat a skillet over medium heat and cook the ground beef, chopped onion, and minced garlic until the beef is browned and the onions are softened. Drain excess fat to avoid a greasy casserole.
2. Transfer to the Slow Cooker
Add the beef mixture to your slow cooker. Then, mix in the cream of mushroom soup, milk, kidney beans, diced tomatoes with green chilies, corn, chili powder, salt, and pepper. Stir everything together to combine the flavors.
3. Layer the Potatoes
Add the sliced potatoes, making sure they are evenly distributed and well-coated in the beef mixture. This ensures they cook evenly and absorb all the delicious flavors.
4. Slow Cook to Perfection
Cover and cook on low for 6–7 hours or high for 3–4 hours until the potatoes are tender.
5. Add the Cheese
In the last 20 minutes of cooking, sprinkle the shredded cheese on top. Cover again and let it melt into the casserole.
6. Serve and Enjoy
Once the cheese is melted, scoop into bowls and serve warm. Pair it with a side salad or some crusty bread for a complete meal!
