Notes & Substitutions

You can easily adapt this Slow Cooker Cowboy Casserole recipe to your pantry or preferences. Feel free to use Yukon Gold or small red potatoes if baby reds are unavailable. Swap out the fire-roasted corn and tomatoes for regular canned versions, or use 1.5 cups of frozen corn and a can of plain diced tomatoes. For beans, pinto or black beans work wonderfully instead of kidney beans. If you prefer, make your own taco seasoning with chili powder, cumin, and paprika to control the spice level. You can also opt for leaner ground beef or ground turkey for a lighter version of this hearty casserole.

Equipment

Gathering your tools before you start makes cooking a breeze.

  • You will need a 6-quart slow cooker for this recipe.
  • A large skillet is essential for browning the meat.
  • Grab a sturdy mixing spoon and a cutting board.
  • A sharp chef’s knife will also be helpful for chopping vegetables.

Instructions

Making this Slow Cooker Cowboy Casserole is straightforward, even for beginners. Follow these simple steps for a perfect meal every time.

Step 1: Brown Beef and Sauté Aromatics

Start by heating the olive oil in a large skillet over medium-high heat. Add the ground beef and salt to the hot skillet. Cook, breaking the beef up with a spoon, until it is fully browned and cooked through, which takes about 6 minutes. Carefully drain any excess fat from the skillet. Next, add the chopped onions, minced garlic, and the entire packet of taco seasoning to the beef. Sauté the mixture, stirring often, until the onions have softened, usually about 3 minutes. This step builds the foundation of flavor for your casserole.

Step 2: Combine in Slow Cooker

Transfer the browned beef mixture from the skillet directly into your 6-quart slow cooker. Now, add the remaining vegetables: the chopped potatoes, rinsed and drained kidney beans, drained fire-roasted corn, and drained fire-roasted diced tomatoes. Pour in the condensed cream of chicken soup and the can of mild or hot diced green chiles (do not drain the chiles). Use your mixing spoon to stir all these ingredients together thoroughly in the slow cooker. Press the mixture down into an even layer, ensuring everything is well combined and submerged.

Step 3: Slow Cook

Cover your slow cooker with its lid. Set the slow cooker to the HIGH setting. To ensure safe and effective use of your slow cooker, it’s important to follow recommended slow cooker food safety guidelines. Allow the Slow Cooker Cowboy Casserole to cook, stirring it occasionally to prevent sticking and ensure even cooking. Continue cooking until the potatoes are completely tender, which typically takes between 3 to 4 hours. The cooking time might vary slightly depending on your slow cooker model, so check the potatoes for doneness.

Step 4: Add Cheese and Finish

Once the potatoes are tender, it is time for the final touch. Sprinkle the shredded Cheddar-Jack cheese evenly over the top of the casserole. Re-cover the slow cooker with the lid. Continue cooking on HIGH until the cheese is beautifully melted and bubbly, which should take approximately 15 minutes. Once the cheese is melted, your comforting Slow Cooker Cowboy Casserole is ready to serve. Garnish each serving generously with a dollop of sour cream and a sprinkle of fresh cilantro leaves for a bright finish.

Pro Tips & Troubleshooting

Achieve the best results for your Slow Cooker Cowboy Casserole with these helpful hints. Always brown your ground beef thoroughly before adding it to the slow cooker; this step significantly enhances the overall flavor. When adding taco seasoning to the skillet, cook it briefly with the onions and garlic to “bloom” the spices, intensifying their aroma. Check potato tenderness with a fork; they should be easily pierced. If you are serving later, hold off on adding the cheese until about 15 minutes before you are ready to eat, or move the slow cooker to a “warm” setting. If your casserole seems too watery, remove the lid for the last 30 minutes of cooking. If it’s too dry, stir in a splash of chicken broth. For faster cooking, ensure your potatoes are cut into smaller, more uniform pieces.
