Ingredients
  

Kielbasa potato casserole
  • 1 lb kielbasa Sliced into rounds.
  • 3 lb Yukon gold potatoes Thinly sliced.
  • 1 onion Diced.
  • 4 garlic Minced.
  • 2 cup sharp cheddar Shredded and divided.
  • 1 cup sour cream
  • 1 can (10.5 oz) cream of chicken soup
  • 0.5 cup chicken broth
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • green onions For garnish.
  • salt and pepper To taste.

Equipment

  • 1 sheet pan
  • 1 cast iron skillet

Method
 

Prep and brown
  1. Preheat the oven to 375°F and grease a 9x13 baking dish.
  2. Brown the kielbasa rounds in a skillet, then set aside.
Make the creamy sauce
  1. Whisk sour cream, cream of chicken soup, broth, garlic powder, and onion powder until smooth.
Layer and bake
  1. Layer half the potatoes in the greased dish, then top with half the onion, garlic, kielbasa, sauce, and 3/4 cup cheddar.
  2. Repeat the layers with the remaining potatoes, onion, garlic, kielbasa, sauce, and top with the remaining cheddar.
  3. Cover with foil and bake for 40 minutes at 375°F.
  4. Uncover and bake for 15 more minutes at 375°F until the top is golden and the potatoes are tender.
Finish
  1. Garnish with green onions and serve.

Notes

For even tenderness, slice the potatoes thin and similar in thickness so they cook at the same rate. Store covered in the refrigerator up to 3 days; reheat in the oven at 350°F until hot throughout. Freezing is not recommended due to texture changes in the dairy sauce. For a lighter option, use low-fat sour cream and reduce cheddar slightly without changing baking time.
