Ingredients
Ground Beef: Browned and drained for maximum flavor. Ground turkey or chicken works too if you prefer lighter meat.
Potatoes: Russet or Yukon Gold, sliced thin or diced. They create a hearty base and soak up all the delicious sauce.
Kidney Beans: Adds fiber, texture, and bulk. Black beans or pinto beans work just as well.
Corn: Sweet corn balances the savory meat and adds pops of color and sweetness.
Cheddar Cheese: Melted on top for the final touch. Sharp cheddar gives the best flavor!
Onion & Garlic: Build a savory foundation for the beef.
Sauce: A mix of tomato soup (or tomato sauce) and taco seasoning creates a tangy, flavorful coating for all the layers.
Seasonings: Taco seasoning, salt, and pepper bring everything together.
Step-by-Step Instructions
1. Brown Beef: Cook ground beef with diced onions and minced garlic in a skillet over medium-high heat until browned. Drain the fat thoroughly to avoid a greasy casserole.
2. Layer: Spray the slow cooker with nonstick spray. Layer sliced potatoes evenly on the bottom, followed by the beef mixture, drained kidney beans, and corn.
3. Sauce: In a bowl, mix tomato soup (or tomato sauce) with taco seasoning and a splash of water. Pour the sauce evenly over all the layers in the slow cooker.
4. Cook: Cover and cook on Low for 6-8 hours, or on High for 3-4 hours, until the potatoes are fork-tender.
5. Cheese: Sprinkle shredded cheddar cheese generously over the top during the last 15 minutes of cooking. Cover and let it melt into gooey perfection.
Tips for Success
Slice Potatoes Thin: Thinner slices (about ¼-inch) cook faster and more evenly. If they’re too thick, they might stay crunchy or undercooked in the center.
Season Layers: Lightly salt and pepper the potato layer so the bottom isn’t bland. Each layer should taste great on its own!
Lean Beef: Use 90% lean ground beef (or leaner) so the casserole doesn’t end up greasy at the bottom. If using fattier beef, drain it really well.
Stir Gently: If you want to mix things up a bit, give everything a gentle stir halfway through cooking to distribute the sauce.
Slow Cooker Cowboy Casserole Variations
Tater Tot Version: Use frozen tater tots on top instead of sliced potatoes inside. Add them during the last hour of cooking for a crispy, golden topping.
Spicy Cowboy: Add diced jalapeños to the beef mixture and use Pepper Jack cheese instead of cheddar for a spicy kick.
BBQ Twist: Swap the tomato soup for your favorite BBQ sauce for a smokier, sweeter flavor profile. It’s delicious!
Vegetarian Cowboy: Replace the ground beef with extra beans (black beans, pinto, or kidney) and add diced bell peppers and mushrooms.
Serving Suggestions
Top each serving with a dollop of sour cream and a sprinkle of sliced green onions for freshness and tang.
Serve with warm cornbread on the side to soak up all that savory sauce.
A crisp coleslaw pairs perfectly with this hearty meat dish and adds a refreshing crunch.
FAQs
Do I have to cook the beef first?
Yes! Browning the beef adds flavor and removes excess grease. Raw ground beef can leave the casserole greasy and lack that deep, caramelized flavor.
Can I use sweet potatoes?
Absolutely! Sweet potatoes add a sweet and savory twist that’s surprisingly delicious. They cook at about the same rate as regular potatoes.
Is this gluten-free?
Yes, as long as you check your taco seasoning and tomato soup labels. Many brands are naturally gluten-free, but it’s always good to double-check.
