Ingredients You’ll Need
One of the best things about the Kielbasa and Potato Casserole Recipe is how straightforward the ingredients are. Each item serves a purpose, from the smoky kielbasa adding a punch of flavor to the creamy sauce that brings everything together. Using fresh aromatics and quality cheese makes all the difference when it comes to taste and texture.
- 3 cups russet potatoes, peeled and cubed: These provide the perfect starchy base, soft and comforting once boiled.
- 1 tablespoon olive oil: Helps brown the kielbasa beautifully without overpowering the dish.
- 1 pound smoked kielbasa sausage, cut into bite-sized pieces: The star protein, smoky and flavorful for a satisfying bite.
- ¼ cup all-purpose flour: Acts as a thickener to give the sauce a smooth, velvety texture.
- ¼ cup unsalted butter: Adds richness and depth when melting garlic and building the sauce.
- 2 teaspoons minced garlic: Provides a fragrant punch that complements the sausage perfectly.
- 1 ½ cups 2% milk: Keeps the sauce creamy yet light enough to let the flavors shine.
- ½ cup heavy cream (33%): Makes the sauce decadently rich and silky smooth.
- ½ teaspoon ground cumin: Adds a subtle warmth and earthiness to balance the richness.
- ½ teaspoon garlic powder: Enhances the garlic flavor while layering complexity.
- 1 teaspoon salt: Essential for seasoning and bringing out the best in every ingredient.
- ½ teaspoon cracked black pepper: Offers a gentle kick and aromatic edge to the dish.
- 1 can (284 ml) cheddar cheese soup: This classic ingredient delivers a creamy cheddar punch throughout the casserole.
- 2 cups shredded sharp cheddar cheese: Creates a bubbly, golden crust that crisps up beautifully when baked.
How to Make Kielbasa and Potato Casserole Recipe
Step 1: Boil Your Potatoes
Start by boiling those cubed russet potatoes in salted water. This step is crucial because you want the potatoes tender but not falling apart. Around 10 to 12 minutes should do the trick—check by piercing with a fork; it should go through easily. After draining, set them aside to cool slightly while you prepare the other components.
Step 2: Brown the Kielbasa
Heat a tablespoon of olive oil in a skillet over medium heat. Toss in the kielbasa pieces and cook them for about 5 to 7 minutes until they get that mouthwatering browned exterior. Browning creates flavor by caramelizing the sausage’s natural sugars and fats, so don’t rush this part! Once browned, remove the kielbasa and set it aside on a plate.
Step 3: Prepare the Creamy Sauce
In the same skillet, melt your butter and add the minced garlic. Cook for about a minute until fragrant, being careful not to burn it. Next, whisk in the flour to make a roux—this forms the base for your sauce. Gradually add the milk and heavy cream while whisking constantly to avoid lumps. Stir in ground cumin, garlic powder, salt, and cracked black pepper for a subtle seasoning depth. Let this mixture simmer gently for 3 to 4 minutes until it thickens to a creamy, smooth consistency.
Step 4: Combine and Transfer
Preheat your oven to 375°F (190°C). In a large bowl, gently mix together the boiled potatoes, browned kielbasa, and the cheddar cheese soup. Pour the creamy sauce over the mixture and stir carefully to coat everything without breaking the potatoes. Transfer this flavorful combination into a greased casserole dish and spread it evenly. Finally, sprinkle the shredded sharp cheddar cheese generously on top—it will bake into a golden, bubbly crown for your casserole.
Step 5: Bake to Perfection
Bake the casserole for about 20 to 25 minutes until it’s hot and bubbly all over. If you want to add a little extra flair, switch your oven to broil for the last 1 to 2 minutes to achieve a crispy, beautifully golden cheese topping. Just keep a close eye so it doesn’t burn!
How to Serve Kielbasa and Potato Casserole Recipe
Garnishes
A sprinkle of freshly chopped parsley or green onions adds a beautiful pop of color and a fresh bite that balances the casserole’s richness. A dollop of sour cream on the side can also bring creaminess and tang, making every forkful even more indulgent.
Side Dishes
This casserole stands strong on its own, but pairing it with a crisp green salad or steamed vegetables like green beans or broccoli brings a welcome lightness to your meal. For those wanting to embrace comfort fully, some soft dinner rolls or crusty bread are perfect for mopping up the luscious sauce.
Creative Ways to Present
Try serving the Kielbasa and Potato Casserole Recipe in individual ramekins for a classy presentation when entertaining. You can also layer it with sautéed bell peppers and onions for added color and texture, or mix in some fresh herbs like thyme or rosemary right before baking for an extra aromatic touch.
Make Ahead and Storage
Storing Leftovers
Leftover casserole is a delight because it tastes even better the next day! Store leftovers in an airtight container in the refrigerator, and it will keep well for up to 3 days. Just give it a gentle stir before reheating to redistribute the sauce evenly.
Freezing
If you want to prepare in advance, this dish freezes beautifully. Assemble the casserole but don’t bake it—wrap tightly in plastic wrap and foil, then freeze for up to 2 months. When you’re ready, thaw overnight in the refrigerator before baking as directed.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15–20 minutes until warm and bubbly. If you’re in a rush, microwaving on medium power works too, but reheating in the oven helps maintain that wonderful crispy cheese topping texture.
FAQs
Can I use a different type of sausage instead of kielbasa?
Absolutely! While kielbasa brings a unique smoky flavor, you can substitute with other smoked sausages or even bratwurst for a slightly different but equally delicious result.
Is it possible to make this recipe dairy-free?
Yes, by swapping the butter for a plant-based alternative, using dairy-free milk such as oat or almond, and choosing a dairy-free cheese substitute, you can make a tasty dairy-free version of this casserole.
What is the best potato to use for this casserole?
Russet potatoes are preferred because they hold up well after boiling, giving you a creamy interior and fluffy texture without falling apart during baking.
Can I prepare this dish ahead of time and bake later?
Definitely! You can assemble the entire casserole, cover it, and refrigerate for up to 24 hours before baking. Just add a few extra minutes to the bake time if it’s coming out cold from the fridge.
How spicy is this recipe?
This Kielbasa and Potato Casserole Recipe is mild in spice, with warmth coming mostly from the cumin and black pepper. If you like it spicier, consider adding some crushed red pepper flakes or hot sauce to the sauce mixture.
