Ingredients

Kielbasa Sausage brings a smoky, meaty flavor that defines the dish. I like to use a well-seasoned smoked kielbasa that gets nicely caramelized when baked.

Potatoes are the heart of this casserole. I prefer using Yukon Golds because of their buttery texture and how well they hold up after baking.

Cheddar Cheese is what turns this into comfort food. The sharpness of the cheese complements the sausage and potatoes while melting into a rich, golden layer.

Onion adds a sweet, savory base to balance the richness of the other ingredients. It’s subtle but makes a huge difference.

Heavy Cream gives the dish its luscious, creamy sauce that ties everything together. It infuses the potatoes and sausage with richness during baking.

Butter helps in sautéing and also deepens the flavor profile with its creamy undertones.

Garlic Powder, Salt, and Pepper provide that final touch of seasoning, elevating the overall flavor.

How to Make Kielbasa Sausage Cheesy Potato Casserole

Step 1: Prep the Ingredients

Peel and cube your potatoes into even-sized chunks so they cook evenly. Slice the kielbasa into thick coins. Dice the onion finely.

Step 2: Sauté the Base

In a large skillet, melt the butter over medium heat. Add the onion and cook until it’s translucent. Then add the kielbasa slices and brown them slightly to bring out their flavor.

Step 3: Assemble the Casserole

In a large mixing bowl, combine the sautéed onion and kielbasa with the cubed potatoes. Stir in garlic powder, salt, pepper, and most of the shredded cheddar. Pour in the heavy cream and mix everything gently but thoroughly.

Step 4: Bake to Perfection

Transfer the mixture into a greased baking dish. Sprinkle the remaining cheese on top. Cover with foil and bake in a preheated oven at 375°F (190°C) for 45 minutes. Then uncover and bake for an additional 15-20 minutes until the top is golden and bubbly.

Step 5: Rest and Serve

Let the casserole rest for about 5-10 minutes before serving. This helps everything set slightly and makes it easier to scoop.

Recipe Variations and Possible Substitutions

If you’re looking to switch things up, there are plenty of ways to personalize this Kielbasa Sausage Cheesy Potato Casserole. Swap the kielbasa with turkey sausage or even a spicy andouille for a different flavor profile. For a vegetarian version, you can use plant-based sausage and load up on bell peppers, mushrooms, and spinach.

Not a fan of heavy cream? You can use sour cream, Greek yogurt, or a mix of milk and cream cheese for a tangy twist. Want it extra cheesy? Add mozzarella or Monterey Jack to the mix. You can also try sweet potatoes for a more unique and slightly sweet spin.

Serving and Pairing Suggestions

This casserole is a complete meal on its own, but if you want to serve it with sides, consider a fresh green salad or some roasted Brussels sprouts for balance. It’s also amazing with a warm slice of crusty bread to mop up all that creamy sauce. For brunch, pair it with scrambled eggs and fresh fruit.

If you’re hosting a cozy dinner or potluck, this dish holds up beautifully on a buffet table. It pairs well with lighter drinks like iced tea, sparkling water, or a crisp apple cider.

Storage and Reheating Tips

Leftovers? You’re in luck. Store any remaining casserole in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm the entire dish in the oven at 350°F until heated through.

For longer storage, you can freeze the casserole. Wrap it tightly in plastic wrap and foil, and store for up to 2 months. Thaw in the refrigerator overnight before reheating. If you’re freezing individual portions, use airtight freezer-safe containers.
