Ingredients
For the Casserole
1. 1 pound (450 g) lean ground beef
2. 1 small onion, diced
3. 2 cloves garlic, minced
4. 1½ pounds potatoes, cut into 1-inch cubes
5. 1 can (15 ounces) black beans, drained and rinsed
6. 1 cup corn kernels, fresh or frozen
7. 1 can (14.5 ounces) diced tomatoes, with juices
8. 1 cup tomato sauce
9. 1 teaspoon smoked paprika
10. 1 teaspoon chili powder
11. 1 teaspoon ground cumin
12. ½ teaspoon dried oregano
13. 1 teaspoon salt, or to taste
14. ½ teaspoon black pepper
15. ½ cup sour cream or plain Greek yogurt
16. 1½ cups shredded sharp cheddar cheese
17. Fresh parsley or green onion, for garnish
How to Make It
1. Brown the beef: Cook the ground beef and onion in a skillet until the beef is browned and the onion is softened. Drain excess fat.
2. Add garlic: Stir in the minced garlic and cook for about 30 seconds.
3. Layer potatoes: Place the cubed potatoes in an even layer in the slow cooker.
4. Add the remaining ingredients: Add the beef and onion, black beans, corn, tomatoes, tomato sauce, and seasonings.
5. Slow cook: Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the potatoes are fork-tender.
6. Stir in creaminess: During the final 10–15 minutes, stir in the sour cream or Greek yogurt.
7. Add cheddar: Sprinkle cheddar over the top, cover, and cook for 5–10 minutes until melted.
8. Garnish and serve: Finish with parsley or green onion and serve hot.
Tips for the Best Cowboy Casserole
1. Cut potatoes evenly: Uniform cubes cook at a similar rate.
2. Brown the beef first: This improves flavor and removes excess grease.
3. Check the potatoes: Start checking near the end of the cooking time so they remain tender rather than mushy.
4. Add dairy near the end: This helps keep the creamy element smooth.
5. Watch the cheese: Keep the lid closed while the cheddar melts for the best finish.
Easy Variations
Ground turkey can replace the beef, while pinto beans can replace black beans. Add bell peppers or jalapeños for more vegetables and heat, or swap cheddar for Monterey Jack. A little cooked bacon can also be added for extra smoky flavor.
Make-Ahead & Storage
Cool leftovers promptly and refrigerate them in a covered container. Reheat gently in the microwave or on the stovetop. Add a splash of broth or water if the casserole thickens during storage.
Serving Suggestions
Top with green onions, fresh parsley, avocado, hot sauce, or a spoonful of sour cream. Serve with a simple green salad or steamed vegetables.
