  • 1 small onion diced onion
  • 2.5 cups shredded cheddar cheese, divided

  • 1 tsp Creole seasoning Or your preferred seasoning blend.
  • to taste salt and pepper

Instructions
 

Preparation

  • Grease the slow cooker with nonstick spray or a little butter to prevent sticking.
  • Place hash browns (fresh diced potatoes), turkey kielbasa pieces, diced onion, and 2 cups of the shredded cheddar into the slow cooker. Toss gently to combine.
  • In a medium bowl, whisk together cream of mushroom soup, sour cream, Creole seasoning, and a pinch of salt and pepper until smooth.
  • Pour the creamy mixture over the potato and turkey kielbasa mixture. Stir gently until everything is evenly coated.
  • Sprinkle the remaining 1/2 cup of cheddar evenly over the top.

Cooking

  • Cover and cook on LOW for 6 hours or HIGH for 4 hours. The casserole is done when potatoes and onions are tender.
  • Let sit 5–10 minutes before serving for easier scooping.

Notes

This casserole reheats and freezes well. For a vegetarian version, replace turkey kielbasa with smoked tempeh or a blend of mushrooms and smoked paprika.
