How to Make Slow Cooker Cheesy Kielbasa Hashbrown Casserole

Grease the slow cooker:
Use butter or a non-stick spray to ensure the casserole doesn’t stick to the pot for an easy cleanup.
Mix the base ingredients:
In the slow cooker, combine the hashbrowns, diced onion, kielbasa, black pepper, onion powder, and 2 cups of the shredded cheese to create the main mixture.
Prepare the creamy sauce:
In a separate bowl, stir the cream of chicken soup, melted butter, milk, and heavy cream until it forms a smooth blend.
Layer and assemble:
Pour the creamy mixture evenly over the hashbrown and kielbasa mixture ensuring everything is coated. Sprinkle the remaining cheese on top to create a golden and cheesy finish.
Cook and serve:
Cover the slow cooker and cook on high for 3 hours until everything is bubbling and perfectly melted. Serve hot for an irresistible cheesy casserole that everyone will love.

Storage Tips

Any leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F for best results or in the microwave if you’re in a hurry.

Ingredient Substitutions

If you do not have kielbasa, you can substitute it with smoked sausage or cooked ham for a slightly different flavor. For a vegetarian version, skip the kielbasa and add sautéed mushrooms or cooked spinach.

Serving Suggestions

Pair this casserole with a fresh green salad, crusty bread, or scrambled eggs to create a balanced meal. It’s also delightful as a stand-alone dish for a hearty breakfast or dinner option.
