Instructions

Prepare the Ingredients: Dice the red potatoes into 1/2 inch cubes, cut the chicken breast into 1-inch cubes, slice the kielbasa into small rounds, and finely dice the white onion.
Combine Base Ingredients in Crockpot: Lightly grease your crockpot, then add the diced potatoes, chicken cubes, sliced kielbasa, diced onion, and 2 cups of shredded cheddar cheese. Mix gently to distribute the cheese among the ingredients.
Make the Creamy Sauce: In a separate bowl, whisk together the can of cream of chicken and herbs soup, sour cream, heavy cream, Italian seasoning, garlic powder, salt, and pepper until fully combined and smooth.
Add Sauce to Crockpot and Mix: Pour the creamy sauce mixture over the potato and meat mixture in the crockpot, then stir carefully to combine all the ingredients evenly.
Add Topping Cheese: Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top of the casserole mixture in the crockpot without stirring it in.
Cook the Casserole: Cover and cook on low for 6 to 8 hours or on high for about 5 hours. The casserole is ready when the potatoes and onions are tender and fully cooked but still holding their shape. Avoid overcooking to prevent the potatoes from becoming mushy.
Serve and Enjoy: Once cooked through, give it a gentle stir if desired, then serve warm for a satisfying cheesy and flavorful meal.

Notes

Cooking time may vary depending on your crockpot model; check potatoes for doneness before serving.
You can substitute kielbasa with smoked sausage or omit for a lighter dish.
For a thicker sauce, add an extra 1/4 cup of sour cream or cream of chicken soup.
This casserole can be prepared the night before and cooked the next day—just refrigerate overnight before slow cooking.
Leftovers store well in the refrigerator for up to 3 days and reheat nicely in the microwave or oven.
