The Essential Ingredients for Your Cowboy Casserole

This recipe comes together with a handful of simple, easy-to-find ingredients. The magic is in how they combine in the slow cooker to create a wonderfully savory and satisfying meal.

For the Hearty Beef Filling

  • Ground Beef: We recommend using lean ground beef (85/15 or 90/10) to minimize grease.
  • Onion & Garlic: These aromatics form the essential flavor base. Use a sweet yellow onion for a milder taste.
  • BBQ Sauce: Choose your favorite brand; a sweet and smoky variety works exceptionally well here.
  • Diced Tomatoes: A can of undrained diced tomatoes adds moisture and a tangy depth.
  • Corn: You can use canned (drained) or frozen corn. It adds a wonderful sweetness and texture.
  • Beans: Pinto or black beans are classic choices, but kidney beans also work great. Be sure to rinse and drain them.
  • Seasoning: A simple mix of chili powder, smoked paprika, and a pinch of salt and pepper brings it all together.

For the Cheesy Tater Tot Topping

  • Frozen Tater Tots: This is the signature topping that makes the casserole so beloved. No need to thaw them first.
  • Cheddar Cheese: Sharp cheddar provides the best flavor, but a Mexican blend or Colby Jack are also excellent choices. Freshly grated cheese melts best!

Step-by-Step Instructions for the Perfect Slow Cooker Cowboy Casserole

Follow these simple steps to create a flawless cowboy casserole. The process is straightforward, ensuring a delicious outcome with minimal effort.

  1. Brown the Beef: In a large skillet over medium-high heat, cook the ground beef and diced onion until the beef is no longer pink and the onion is softened. Drain any excess grease, then stir in the minced garlic and cook for another minute until fragrant.
  2. Build the Base: Transfer the beef mixture to the basin of your slow cooker. Add the BBQ sauce, diced tomatoes, corn, beans, chili powder, and smoked paprika. Stir everything together until well combined.
  3. Slow Cook to Perfection: Cover the slow cooker and cook on LOW for 4-5 hours or on HIGH for 2-3 hours. This slow simmer allows the flavors to meld and deepen beautifully.
  4. Add the Topping: About 30 minutes before serving, remove the lid. Arrange the frozen tater tots in a single layer over the top of the beef mixture. Sprinkle the shredded cheddar cheese evenly over the tots.
  5. Final Melt: Place the lid back on the slow cooker and continue to cook for another 30-45 minutes, or until the tater tots are cooked through and the cheese is bubbly and melted. For an extra crispy topping, you can carefully transfer the slow cooker’s ceramic insert into the oven and broil for 2-3 minutes (ensure your insert is oven-safe first!).

Expert Tips for Success

A few simple tips can elevate your casserole from great to absolutely unforgettable. For another cheesy and comforting dish, you might also love this classic tater tot casserole.

  • Don’t Skip Browning: Browning the beef and onions before adding them to the slow cooker is a crucial step. It adds a deep, caramelized flavor that you won’t get otherwise.
  • Grate Your Own Cheese: Pre-shredded cheese is often coated in anti-caking agents that can prevent it from melting smoothly. Grating a block of cheese yourself will result in a much creamier, gooier topping.
  • Layer, Don’t Stir (At the End): When you add the tater tots and cheese, layer them on top without stirring them into the filling. This ensures the tots get crispy rather than soggy.

Fun Variations to Try

While this recipe is fantastic as is, it’s also incredibly versatile. Feel free to customize it to your family’s tastes!

  • Switch Up the Meat: Try using ground turkey or ground chicken for a leaner option. You could even use shredded rotisserie chicken.
  • Add Some Spice: For a spicy kick, add a diced jalapeño with the onion or include a pinch of cayenne pepper with the other seasonings.
  • Veggie-Load It: Feel free to add more vegetables like diced bell peppers or mushrooms. Sauté them with the onion and ground beef. For a great side, try these honey-roasted carrots.

Equipment

  • 1 Slow Cooker 6-quart or larger recommended
  • 1 Large Skillet

Instructions

  2. Transfer the beef mixture to a 6-quart or larger slow cooker. Add the BBQ sauce, undrained diced tomatoes, drained corn, rinsed beans, chili powder, and smoked paprika. Stir until everything is well combined.
  3. Cover and cook on LOW for 4-5 hours or on HIGH for 2-3 hours.

Notes
