Ingredients for the Kielbasa Sausage Cheesy Potato Casserole

Kielbasa sausage: The smoky, savory heart of this dish that infuses every bite with bold flavor.
Russet potatoes: Perfect for baking, they hold their shape while soaking up the creamy cheese sauce.
Cheddar cheese: Melts beautifully and adds that irresistible gooey, cheesy richness.
Onion: Adds sweet aromatic depth and blends perfectly with the sausage.
Cream of chicken soup: The base for a rich, velvety sauce that ties everything together.
Sour cream: Gives the casserole a smooth texture and slight tang to balance the cheese.
Milk: Helps loosen the sauce for even coverage and a silky finish.
Garlic powder & black pepper: Simple seasoning that enhances all the savory notes.
Fresh parsley (optional): For a pop of color and fresh flavor just before serving.

How To Make the Kielbasa Sausage Cheesy Potato Casserole

Step 1: Prep the Ingredients

Peel and dice the potatoes into bite-sized chunks. Thinly slice the onion and cut the kielbasa into 1/2-inch rounds. Preheat your oven to 375°F (190°C).

Step 2: Sauté the Sausage and Onion

In a large skillet over medium heat, sauté the sliced kielbasa for 3-4 minutes until lightly browned. Add the onions and cook until soft and translucent. This step builds the base flavor of your casserole.

Step 3: Mix the Creamy Sauce

In a mixing bowl, stir together cream of chicken soup, sour cream, milk, garlic powder, and black pepper. Add in 1 1/2 cups of shredded cheddar cheese and mix until fully combined.

Step 4: Layer the Casserole

In a greased 9×13-inch baking dish, add the diced potatoes, sautéed sausage, and onion. Pour the creamy cheese mixture over the top and gently stir to combine everything evenly.

Step 5: Bake to Perfection

Cover the baking dish with aluminum foil and bake for 50-60 minutes, or until the potatoes are fork-tender. Remove the foil, sprinkle the remaining cheddar cheese on top, and return to the oven uncovered for an additional 10-15 minutes until bubbly and golden.

Step 6: Garnish and Serve

Let it rest for 5-10 minutes before serving. Sprinkle with chopped parsley for a fresh finish if desired.

Serving and Storing Kielbasa Sausage Cheesy Potato Casserole

This casserole is best served warm straight from the oven when the cheese is bubbly and golden. Pair it with a crisp green salad or steamed green beans for a well-rounded meal. It also works great as a standalone dish for casual dinners or family gatherings.

To store: Transfer leftovers to an airtight container and refrigerate for up to 4 days. Reheat individual portions in the microwave or warm the entire dish in the oven at 350°F covered with foil until heated through.

To freeze: Assemble the casserole but skip the baking step. Wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge and bake as directed.

Frequently Asked Questions

Can I use other types of sausage?

Absolutely! Andouille, smoked turkey sausage, or even spicy chorizo work well depending on the flavor profile you’re after.

Can I make this ahead of time?

Yes. You can assemble the dish the night before, cover it tightly, and refrigerate. Simply pop it in the oven when you’re ready to bake.

What potatoes are best for this recipe?

Russet potatoes are ideal because they hold their shape during baking while absorbing all the flavors.

Is it okay to add veggies?

Of course! Feel free to add frozen peas, bell peppers, or even broccoli florets for a veggie-packed version.

How do I make it spicier?

Add a pinch of cayenne pepper or stir in chopped jalapeños with the sausage for some extra heat.

Can I use shredded hash browns instead of fresh potatoes?

Yes, just make sure they’re thawed and well-drained before mixing them in. Reduce the cooking time slightly since they’re already par-cooked.
