Ingredients
  

  • 1 lb ground beef
  • 1 small onion chopped
  • 2 cloves garlic minced
  • 4 medium potatoes thinly sliced
  • 1 10.5 oz can cream of mushroom soup
  • 1/2 cup milk
  • 1 15 oz can diced tomatoes with green chilies
  • 1 15 oz can kidney beans, drained and rinsed
  • 1 cup frozen corn
  • 1 teaspoon chili powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 1/2 cups shredded cheddar cheese

Instructions
 

  • Brown the Beef: In a large skillet, cook the ground beef, onion, and garlic over medium heat until the beef is browned. Drain any excess fat.
  • Combine Ingredients: Transfer the beef mixture to a slow cooker. Add the cream of mushroom soup, milk, diced tomatoes with green chilies, kidney beans, frozen corn, chili powder, salt, and black pepper. Stir until well mixed.
  • Add the Potatoes: Layer the thinly sliced potatoes over the beef mixture, stirring slightly to coat them in the sauce.
  • Slow Cook: Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until the potatoes are tender.
  • Add Cheese: In the last 20 minutes, sprinkle shredded cheddar cheese on top, cover, and let it melt.
  • Serve: Scoop onto plates and enjoy warm!

Notes

  • Make it Spicy: Add diced jalapeños, cayenne pepper, or chipotle powder for extra heat.
  • Meat Variations: Swap ground beef for ground turkey, chicken, or sausage for a different flavor.
  • Bean Alternatives: Use black beans or pinto beans instead of kidney beans.
  • Storage: Store leftovers in an airtight container in the fridge for up to 4 days or freeze for up to 3 months.
