Instructions

Lightly grease the slow cooker with cooking spray or use a crockpot liner to prevent sticking and make cleanup easier.
Add the kielbasa chunks, frozen hashbrowns, diced onion, and 2 cups shredded cheddar cheese into the slow cooker. Stir gently to distribute the ingredients evenly.
In a medium mixing bowl, whisk together the cream of mushroom soup, sour cream, and milk until smooth and creamy.
Add minced garlic, onion powder, salt, and black pepper to the sauce mixture. Stir well to combine the seasonings.
Pour the creamy soup mixture over the sausage and hashbrowns in the slow cooker. Mix everything together until evenly coated.
Sprinkle the remaining 1/2 cup shredded cheddar cheese over the top of the casserole.
Cover with the lid and cook on LOW for 6 hours or on HIGH for 3–4 hours until the casserole is hot, bubbly, and the potatoes are tender.
Let the casserole rest for about 5 minutes before serving, then scoop and serve warm.

Notes

Add 1/4 teaspoon paprika or cayenne pepper for a slight spicy kick.
You can substitute kielbasa with smoked turkey sausage or diced ham.
Freshly shredded cheddar melts better than pre-shredded cheese.
Add vegetables like diced bell peppers, spinach, or mushrooms for extra flavor and nutrition.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
