Description

This Slow Cooker Cowboy Casserole is a cozy, rustic one-pot meal with ground beef, tender potatoes, creamy sauce, and melted cheddar cheese—perfect for family dinners or make-ahead comfort.


Ingredients

Scale
  • 1.5 lbs ground beef
  • 4 cups thinly sliced russet or Yukon gold potatoes
  • 1 (15 oz) can corn, drained
  • 1 (15 oz) can kidney or pinto beans, drained and rinsed
  • 1 (10 oz) can diced tomatoes (or fire-roasted/Rotel)
  • 1 (10.5 oz) can cream of mushroom soup
  • 1 cup shredded cheddar cheese, divided
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1/2 tsp paprika
  • Salt and pepper, to taste
  • Nonstick cooking spray

Instructions

  1. Spray the inside of the slow cooker with nonstick spray.
  2. Layer the sliced potatoes on the bottom of the slow cooker.
  3. Add ground beef on top, breaking it up into chunks. (Optional: brown beforehand for extra flavor.)
  4. Top with drained beans, corn, and diced tomatoes.
  5. Sprinkle with garlic powder, onion powder, paprika, salt, and pepper.
  6. Spoon cream of mushroom soup over the top—do not stir.
  7. Cover and cook on low for 6–7 hours or high for 3.5–4 hours.
  8. 30 minutes before serving, sprinkle in half the cheddar cheese. Cover and cook until melted.
  9. Serve hot, topped with remaining cheese, sour cream, green onions, or hot sauce as desired.

Notes

Store leftovers in the fridge for up to 4 days or freeze for up to 3 months. Reheat with a splash of broth to restore creaminess. Great with cornbread or crushed tortilla chips for added crunch.
