- 2 cups cheddar cheese, divided
- ½ cup sour cream

How to Make Dump and Go Kielbasa Casserole
This is truly a dump-and-go recipe—no extra pots, no browning meat, no stress. Just layer, stir, and walk away.
Step 1: Mix the Base
Lightly grease the inside of your slow cooker with nonstick spray or a small amount of oil. Add the sliced kielbasa, frozen hash browns, diced onion, and 1 cup of cheddar cheese. Gently toss the ingredients to distribute evenly.
Step 2: Make the Sauce
In a medium mixing bowl, combine the cream of mushroom or chicken soup, milk, sour cream, salt, pepper, garlic powder, and onion powder. Stir until well-blended into a smooth sauce.
Step 3: Assemble the Casserole
Pour the prepared sauce evenly over the ingredients in the slow cooker. Use a spoon or spatula to gently mix everything together, ensuring the sauce coats the potatoes and sausage well.
Sprinkle the remaining 1 cup of cheddar cheese over the top to create a melted, golden topping once cooked.
Step 4: Cook Low and Slow
Cover the slow cooker with the lid and set it to:
- Low for 6 to 8 hours
- High for 3 to 4 hours
Avoid lifting the lid too often, as that can slow the cooking process. The dish is done when the hash browns are tender, the cheese is melted, and everything is bubbling.
Step 5: Serve and Enjoy
Scoop into bowls and serve hot. This casserole pairs perfectly with a crisp green salad, roasted vegetables, or buttered dinner rolls.
Tips for the Best Kielbasa Casserole
- Use Smoked Kielbasa: It adds a deep, savory flavor that complements the creamy sauce and cheese.
- Customize with Veggies: Try adding diced bell peppers, mushrooms, or thawed frozen broccoli to sneak in some greens.
- Make It Spicy: Add a dash of hot sauce or a sprinkle of red pepper flakes to the sauce if you like heat.
- Crispier Texture: For a crisp top, transfer the cooked casserole to a baking dish, top with breadcrumbs and extra cheese, then broil for 3–5 minutes.
- Storage and Reheating: Refrigerate leftovers in an airtight container for up to 4 days. Reheat in the microwave or oven until warmed through.
Frequently Asked Questions
Can I make this recipe ahead of time?
Yes! You can assemble all ingredients in the slow cooker insert the night before, cover it, and store it in the fridge. In the morning, just place the insert in the cooker and start cooking.
Can I use fresh potatoes instead of frozen hash browns?
Yes, you can. Just peel and shred or dice the potatoes. Make sure to soak and pat them dry first to remove excess starch and prevent sogginess.
Can I freeze this casserole?
Definitely. Let it cool completely, then transfer it to a freezer-safe container. It’ll keep for up to 2 months. Thaw overnight in the fridge and reheat in the oven or microwave.
What can I use instead of kielbasa?
Smoked sausage, turkey sausage, or even leftover cooked chicken or ham work well. Just slice or cube them and follow the same instructions.
Can I cook this in the oven instead of a slow cooker?
Yes. Layer all the ingredients in a greased 9×13 baking dish and bake at 375°F (190°C) for about 45–55 minutes, or until hot and bubbly.
Is this recipe gluten-free?
It can be, if you use a gluten-free cream of mushroom or chicken soup. Always check labels on packaged ingredients to be sure.
