Preparation Phase & Tools to Use
Before you begin creating your Kielbasa Sausage Cheesy Potato Casserole, it’s essential to prepare your kitchen and gather the necessary tools. First, ensure you have a clean and organized workspace to make the cooking process smooth and enjoyable.
Here are some key tools you will need:
- 9×13-inch baking dish: This is perfect for layering your delicious ingredients and enables even cooking.
- Skillet: Ideal for browning the kielbasa and sautéing the onions and garlic for enhanced flavors.
- Large mixing bowl: This will allow you to combine the creamy sauce and other ingredients effectively.
- Knife and cutting board: For chopping potatoes, vegetables, and sausage uniformly.
- Measuring cups and spoons: Precision is essential, especially when working with spices and liquids.
Once your tools are in place, preheat your oven to 375°F (190°C) and grease your baking dish to ensure an easy release after baking. Wash and cube your potatoes so they are ready to be parboiled. This step can enhance their texture, helping them absorb the flavors of the sauce beautifully.

Ingredients
- 2 pounds russet or Yukon Gold potatoes, peeled and cut into 1-inch cubes
- 14 ounces kielbasa sausage, sliced into ¼-inch rounds
- 2 cups sharp cheddar cheese, freshly shredded
- 1 cup mozzarella cheese, freshly shredded
- 1 small yellow onion, finely diced
- 3 cloves garlic, minced
- 1 ½ cups heavy cream
- ½ cup sour cream
- 2 tablespoons unsalted butter, melted
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon smoked paprika
- ½ teaspoon dried thyme
- ½ teaspoon dried parsley
- ¼ teaspoon crushed red pepper flakes
- 2 tablespoons fresh parsley, chopped
Instructions
Step 1: Preheat the Oven and Prepare the Baking Dish
Start by preheating your oven to 375°F (190°C), which will provide the perfect baking environment for your casserole. While the oven heats, grab your 9×13-inch baking dish and grease it generously to prevent sticking. This ensures easy serving and cleanup later on.
Step 2: Parboil the Potatoes
Next, peel and cube your potatoes into 1-inch pieces for even cooking. Rinse the cubes under cold water to remove excess starch, which can lead to gummy texture. If desired, you can parboil these potato cubes for about 8 to 10 minutes in salted water. This step helps to soften them slightly, preparing them to soak in the sauce’s incredible flavor during baking. After parboiling, drain the potatoes and set them aside.
Step 3: Brown the Kielbasa
To enhance the flavor of your casserole, heat a skillet over medium heat and add the sliced kielbasa. Cook for 3-4 minutes on each side, allowing them to caramelize nicely. This process develops a rich, smoky flavor that becomes the backbone of your dish.
Step 4: Sauté the Onions and Garlic
In the same skillet, add the finely diced onion. Sauté for around 3-4 minutes until it becomes translucent and aromatic. Finally, toss in the minced garlic and cook for an additional 30 seconds, just until fragrant. These ingredients are essential for layering on the flavor profile.
Step 5: Create the Creamy Sauce
Now, in a large mixing bowl, whisk together the heavy cream, sour cream, and melted butter until smooth. Season the mixture with salt, black pepper, smoked paprika, dried thyme, dried parsley, and crushed red pepper flakes for a hint of spice. This creamy concoction brings richness that complements the other ingredients perfectly.
Step 6: Mix in the Cheeses
With your sauce ready, fold in 1 ½ cups of sharp cheddar and ½ cup of mozzarella cheese. The more cheese, the better—mix well so it becomes a cohesive, cheesy wonder.
Step 7: Combine Ingredients in the Baking Dish
In the prepared baking dish, combine the parboiled potatoes, browned kielbasa, sautéed onions, and garlic. Pour the creamy cheese sauce over the top, and gently mix everything together to ensure that the potatoes and sausages are well-coated with the delicious sauce.
Step 8: Layer with Cheese
To take your casserole over the top, sprinkle the remaining amounts of cheddar and mozzarella cheese evenly on top of the mixture. This will create that irresistible, gooey top layer.
Step 9: Bake to Perfection
Cover the dish with aluminum foil and bake for 30 minutes. After that, remove the foil and continue baking for an additional 20-25 minutes. You’re aiming for a golden, bubbly top and fork-tender potatoes.
Step 10: Rest and Serve
Once baked, allow the casserole to rest for 10-15 minutes before serving. This helps the sauce thicken and makes portioning easier. Garnish with fresh parsley to add a pop of color and freshness just before serving.

- Protein: Swap out kielbasa for chicken, turkey, or even a vegetarian sausage for different flavor profiles.
- Vegetables: Add in mixed veggies like bell peppers, broccoli, or carrots for added nutrition and color.
- Spices: Experiment with different spices like Italian seasoning or Cajun spice for a unique twist.
Cooking Notes

- Let the casserole set for a few moments after baking to allow the sauce to thicken properly.
