  • 1 can (15 oz) kidney beans, drained and rinsed
  • 1 can (15 oz) corn, drained
  • 1 can (14.5 oz) diced tomatoes, undrained
  • 1 small onion, diced
  • 1 packet (1 oz) taco seasoning
  • 1 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • ½ teaspoon salt (adjust to taste)
  • ½ teaspoon black pepper
  • 1 can (10.5 oz) cream of mushroom soup
  • 1 ½ cups shredded cheddar cheese

Optional Garnishes:

  • Fresh parsley or cilantro, chopped
  • Sour cream
  • Green onions, sliced
  • Crushed tortilla chips for extra crunch

Instructions

Step 1: Prepare the Ingredients

  1. In a skillet over medium heat, brown the ground beef until fully cooked. Drain excess fat.
  2. Add the diced onions to the beef and cook until softened (about 3 minutes).

Step 2: Assemble the Casserole in the Slow Cooker

  1. Spray the inside of the slow cooker with non-stick cooking spray.
  2. Layer the diced potatoes at the bottom, followed by the cooked ground beef and onions.
  3. Add the black beans, kidney beans, corn, and diced tomatoes (with their juices).
  4. Sprinkle the taco seasoning, smoked paprika, garlic powder, salt, and black pepper evenly over the layers.
  5. Pour the cream of mushroom soup over the top and spread evenly. Do not mix.

Step 3: Slow Cook the Casserole

  1. Cover and cook on low for 6–7 hours or high for 3–4 hours, until the potatoes are tender.

Step 4: Add the Cheese

  1. In the last 30 minutes of cooking, sprinkle shredded cheddar cheese over the casserole. Cover and allow the cheese to melt.

Step 5: Serve and Enjoy

  1. Once done, garnish with fresh parsley, sour cream, or green onions if desired. Serve warm and enjoy!

Notes

  • For a thicker casserole: Leave the lid slightly ajar during the last 30 minutes of cooking to let excess moisture evaporate.
  • Make it spicy: Add diced jalapeños or a dash of hot sauce.
  • Vegetarian alternative: Swap the ground beef for extra beans or plant-based meat.
  • Storage: Leftovers can be stored in an airtight container in the fridge for up to 3 days.
  • Freezing: Freeze in portioned containers for up to 3 months. Thaw overnight and reheat before serving.
