Can I Use Any Type of Kielbasa or Sausage?

Absolutely! Kielbasa is traditionally a Polish smoked sausage that adds great depth to this dish.

For a slightly spicier edge, chorizo or Cajun sausage can also do wonders.

Ingredients for the Kielbasa Sausage Cheesy Potato Casserole

This dish calls for simple ingredients you likely already have in your pantry or fridge. Each one contributes to the creamy texture and bold flavor.

• Kielbasa sausage: This smoked sausage is the star of the dish, bringing savory, rich flavor to every bite.
• Frozen hash browns: They make prep quick and easy, offering the perfect potato base that crisps up nicely on the edges.
• Shredded cheddar cheese: Melts into a creamy layer and gives the casserole that signature cheesy finish.
• Cream of mushroom soup: Helps bind everything together while adding a comforting creaminess.
• Sour cream: Adds tang and smooth texture to the sauce.
• Chopped onions: Give the dish a little bite and boost of flavor.
• Butter: Helps with richness and browning.
• Garlic powder and black pepper: Adds warmth and mild spice without overpowering.

How To Make the Kielbasa Sausage Cheesy Potato Casserole

Step 1: Prep the Baking Dish

Preheat your oven to 375°F and lightly grease a 9×13-inch baking dish. This ensures nothing sticks and clean-up is easier.

Step 2: Cook the Kielbasa

Slice the kielbasa into bite-sized pieces and brown them in a skillet over medium heat. This brings out even more flavor and gives the edges a nice crisp.

Step 3: Mix the Base

In a large bowl, combine frozen hash browns, sour cream, cream of mushroom soup, chopped onions, garlic powder, black pepper, and half the shredded cheese. Stir until everything is well mixed.

Step 4: Assemble the Casserole

Pour the potato mixture into the baking dish, spreading it evenly. Nestle the browned kielbasa pieces throughout the top and sprinkle the remaining cheddar cheese across the surface.

Step 5: Bake to Golden Perfection

Bake uncovered for 40-45 minutes, or until the top is golden and bubbly. Let it rest for a few minutes before serving to set.

How to Serve and Store Kielbasa Sausage Cheesy Potato Casserole

This casserole feeds about 6 to 8 people, depending on serving size. Serve it warm straight from the oven with a sprinkle of parsley or green onion for freshness. It’s filling enough to be a main dish, but can also play well as a side at gatherings.

To store leftovers, let the casserole cool completely before transferring it to an airtight container. Refrigerate for up to 4 days or freeze for up to 2 months. Reheat in the oven at 350°F until warmed through.
