Kielbasa Sausage Cheesy Potato Casserole Ingredients
For the Casserole
• Smoked Kielbasa Sausage – Adds savory flavor and protein; you can substitute with turkey kielbasa for a lighter option.
• Frozen Diced Hash Brown Potatoes – Provides the base and texture; no need to thaw before mixing, but freshly shredded potatoes must be soaked and dried first.
• Cream of Chicken Soup – Creates a creamy sauce; substitute with cream of mushroom or celery soup for variation.
• Sour Cream – Adds creaminess and tang; Greek yogurt can serve as a lighter alternative.
• Shredded Cheddar Cheese (divided) – Contributes rich flavor and melty texture; freshly shredded cheese melts better than pre-shredded varieties, but mozzarella can also add creaminess.
• Chopped Green Onions – Provides freshness and a slight bite; sautéed white onions work as a milder alternative.
• Garlic Powder, Black Pepper, Paprika – Essential seasonings that enhance the overall flavor profile.
• Butter (melted) – Used to mix with toppings for added crunch.
For the Topping
• Crushed Cornflakes or Ritz Crackers – Adds a delightful crunch on top; these optional toppings can elevate the dish and provide great texture.

Step‑by‑Step Instructions for Kielbasa Sausage Cheesy Potato Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grab a 9×13-inch baking dish and grease it lightly with butter or cooking spray. This will ensure that your Kielbasa Sausage Cheesy Potato Casserole bakes evenly and doesn’t stick to the pan, setting the stage for a deliciously gooey texture.
Step 2: Mix the Creamy Base
In a large mixing bowl, combine the cream of chicken soup, sour cream, and 1.5 cups of shredded cheddar cheese. Add the chopped green onions along with the garlic powder, black pepper, and paprika. Stir the mixture vigorously until it’s smooth and well-blended. You should see a creamy blend, rich in flavor, that will coat your potatoes beautifully.
Step 3: Add the Potatoes
Now, fold in the frozen diced hash brown potatoes, ensuring each piece is well-coated with the creamy mixture. There’s no need to thaw the potatoes beforehand; they will bake up perfectly in the oven. The mixture will begin to thicken, becoming a hearty base for your Kielbasa Sausage Cheesy Potato Casserole.
Step 4: Incorporate the Kielbasa
Gently stir in the sliced kielbasa sausage, ensuring it’s evenly distributed throughout the potato mixture. This step adds a delicious smokiness to the casserole that really elevates the flavors. You want to see chunks of sausage throughout, inviting warmth and depth into every bite of this comforting dish.
Step 5: Transfer to Baking Dish
Spread the potato and kielbasa mixture evenly into the prepared baking dish. Use a spatula to smooth out the top, making sure it’s distributed evenly to promote even baking. This layer will bubble up beautifully as it cooks, transforming into the cheesy casserole everyone loves.
Step 6: Add the Cheesy Topping
Sprinkle the remaining shredded cheddar cheese generously over the top of the casserole. For an added layer of crunch, mix melted butter with your choice of crushed cornflakes or Ritz crackers before sprinkling them over the cheese. This crunchy topping will offer delightful contrast to the creamy cheesy goodness below.
Step 7: Bake to Perfection
Place the baking dish in the preheated oven and bake uncovered for 40–45 minutes. Keep an eye on it; the casserole is ready when the top is golden brown and bubbly, with edges slightly crispy. The delicious aroma of melted cheese will fill your kitchen, letting you know that dinner is almost ready!
Step 8: Rest Before Serving
Once baked, remove the Kielbasa Sausage Cheesy Potato Casserole from the oven and let it rest for 5–10 minutes. This allows the flavors to meld and makes it easier to serve. The casserole will be hot and bubbly, so be cautious as you dip into this warm, comforting dish.

Kielbasa Sausage Cheesy Potato Casserole Recipe FAQs
What kind of kielbasa should I use?
Absolutely! I recommend using smoked kielbasa for its rich and savory flavor. If you’re looking for a lighter option, turkey kielbasa works beautifully as well. It’s still packed with flavor while being a bit healthier.
Can I use fresh potatoes instead of frozen hash browns?
Very! If you choose to use fresh potatoes, make sure to peel and shred them. Soak the shredded potatoes in cold water for about 30 minutes to remove excess starch. This step is crucial for achieving a fluffy and non-gummy texture in your casserole. After soaking, drain and pat them dry before mixing into your casserole base.
How should I store leftovers of the Kielbasa Sausage Cheesy Potato Casserole?
Absolutely! Place leftovers in an airtight container and refrigerate. They’ll stay fresh for up to 4 days. Make sure to let it cool completely before sealing. This helps maintain its rich, cheesy goodness and prevents moisture loss.
Can I freeze the casserole for later?
Very! To freeze, individually wrap portions tightly in foil or use freezer-safe bags to prevent freezer burn. This way, they can be stored for up to 3 months. When you’re ready to enjoy it, simply thaw overnight in the fridge and reheat in a preheated oven at 350°F (175°C) covered with foil for 25–30 minutes.
What if my casserole isn’t browning on top?
Don’t worry! If your Kielbasa Sausage Cheesy Potato Casserole isn’t browning nicely, try broiling the top for the last 2-3 minutes of baking. Just keep a close eye on it to prevent burning! This step can help achieve that beautiful golden finish.
Are there any dietary considerations I should be aware of?
Definitely! For a gluten-free option, ensure you use gluten-free cream of chicken soup and check the labels on your sausage and toppings. If you’re preparing for someone with dairy allergies, consider using dairy-free alternatives for sour cream and cheese, like cashew cream and vegan cheese, for a deliciously inclusive casserole.
