How to Make Kielbasa Sausage Cheesy Potato Casserole Recipe
Step 1: Brown the Kielbasa
Start by warming a large skillet over medium heat to brown the sliced kielbasa. Cook it for about 5 to 7 minutes until each piece has a light golden crust. This step unlocks the rich smoky flavors and gives a satisfying texture that contrasts beautifully with the creamy potatoes later on.
Step 2: Mix the Potato Base
In a spacious bowl, combine your thawed hash brown potatoes, diced onion, cream of chicken soup, sour cream, milk, melted butter, garlic powder, paprika, black pepper, and salt. Mix everything thoroughly to ensure every bite is packed with flavor and creamy texture – this is the heart of the Kielbasa Sausage Cheesy Potato Casserole Recipe.
Step 3: Combine and Layer
Gently fold in the browned kielbasa along with half of the cheddar and mozzarella cheeses. Then spread the whole mixture evenly into a lightly greased 9×13-inch baking dish. This layering method ensures the flavors meld beautifully as it bakes.
Step 4: Add the Cheese Topping and Bake
Sprinkle the remaining cheddar and mozzarella evenly over the top. Cover your dish loosely with foil to keep it moist and bake at 375°F for 30 minutes. After that, remove the foil and bake an additional 15 to 20 minutes until the casserole is bubbling hot and the top is a gorgeous, golden brown color.
Step 5: Rest and Garnish
Once out of the oven, let the casserole sit for about 5 minutes. This resting period lets everything set nicely so you get perfect, neat slices. If you like, sprinkle with fresh parsley for a pop of color and a touch of brightness on your plate.
How to Serve Kielbasa Sausage Cheesy Potato Casserole Recipe
Garnishes
A little fresh parsley is a classic choice, but feel free to sprinkle some chopped green onions or a light dusting of paprika for an extra splash of color and flavor contrast.
Side Dishes
This casserole is hearty on its own but pairs beautifully with a crisp garden salad or steamed green veggies like broccoli or green beans. The freshness of the sides cuts through the richness, making your meal balanced and satisfying.
Creative Ways to Present
Try serving individual portions in small ramekins for a charming, crowd-pleasing presentation. You can also top each serving with a dollop of sour cream or a drizzle of spicy mustard to elevate the flavors impressively.
Make Ahead and Storage
Storing Leftovers
Place any leftovers in an airtight container and refrigerate. This casserole keeps well for up to 3 days and tastes even better the next day as the flavors continue to meld.
Freezing
You can freeze the casserole either before or after baking. Wrap it tightly with plastic wrap and foil to prevent freezer burn, and it will keep for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
To reheat, cover with foil and warm in a 350°F oven until heated through, about 20-25 minutes. For a crispy top, remove the foil during the last 5 minutes of reheating.
FAQs
Can I use fresh potatoes instead of frozen hash browns?
Absolutely! Just peel and shred fresh potatoes, then squeeze out excess moisture before mixing. This will keep your casserole from becoming too watery.
Is smoked kielbasa preferred for this recipe?
Yes, smoked kielbasa adds a rich, deep flavor that really makes this casserole shine, but you can use fresh kielbasa if that’s what you have on hand.
Can I make this recipe vegetarian?
To go vegetarian, substitute the kielbasa with smoked tofu or a meatless sausage alternative, and use vegetable soup in place of cream of chicken soup.
How spicy is this casserole?
This casserole is mild and comforting, but you can add a pinch of crushed red pepper flakes or some diced jalapeños if you want to give it a little kick.
Can I prepare this casserole the night before and bake later?
Yes! Prepare the casserole and keep it covered in the fridge overnight. Bake it fresh the next day for a convenient, home-cooked meal with little morning fuss.

There is nothing quite like a warm, cheesy, and savory casserole straight from the oven, and this Kielbasa Sausage Cheesy Potato Casserole Recipe truly delivers that cozy magic. It’s straightforward, satisfying, and packed with layers of flavor that will keep you coming back for more.
