How to Make Slow Cooker Cowboy Casserole
- Brown the Beef: In a skillet over medium heat, cook the ground beef with chopped onion and minced garlic until the beef is browned and the onions are softened. Drain any excess fat.
- Combine Ingredients in the Slow Cooker: Transfer the beef mixture to your slow cooker. Add the cream of mushroom soup, milk, kidney beans, diced tomatoes with green chilies, frozen corn, chili powder, salt, and black pepper. Stir to combine.
- Add the Potatoes: Layer the sliced potatoes on top of the mixture, ensuring they are well-coated with the beef and sauce.
- Slow Cook: Cover and cook on low for 6–7 hours or on high for 3–4 hours, depending on your schedule.
- Melt the Cheese: In the last 20 minutes of cooking, sprinkle shredded cheese over the casserole and let it melt before serving.
Storage Tips
Leftovers store beautifully in the fridge for up to 3-4 days in an airtight container. Reheat on the stovetop or in the microwave for a quick meal. For longer storage, freeze portions for up to 3 months. Just thaw in the fridge overnight before reheating. The flavors actually improve after sitting for a bit, making it perfect for meal prep!
Variations and Substitutions
- Meat Variations: Swap the ground beef for turkey, chicken, or pork for a lighter option, or add diced sausage or chorizo for a smoky twist.
- Beans: Experiment with different beans, such as black beans, pinto beans, or even chickpeas. Baked beans will add extra richness.
- Potato Alternatives: Try sweet potatoes for a hint of sweetness or low-carb alternatives like butternut squash or cauliflower.
- Spice It Up: Add jalapeños, chipotle peppers, or a dash of hot sauce for extra heat, or use spicy salsa for a smoky flavor.
Serve With
This casserole pairs wonderfully with a fresh side salad to balance the richness of the dish. For a comforting touch, serve it with cornbread or steamed green beans for a complete, satisfying meal.
