Step‑by‑Step Instructions for Kielbasa Sausage Cheesy Potato Casserole
Step 1: Preheat and Prepare Baking Dish
Start by preheating your oven to 375°F (190°C). While the oven heats up, grab a 9x13-inch baking dish and generously grease it with cooking spray or butter. This ensures easy removal later on. The casserole will be ready to receive its cheesy, hearty filling shortly!
Step 2: Prepare the Kielbasa
Slice the smoked kielbasa into half-moons, about ¼-inch thick. For extra flavor, heat a skillet over medium heat and brown the slices for 3-4 minutes until they are slightly crispy on the edges. This step enhances the smoky flavor and adds depth to your Kielbasa Sausage Cheesy Potato Casserole.
Step 3: Mix the Creamy Base
In a large mixing bowl, combine the cream of chicken soup and sour cream to create a creamy base. Add 1.5 cups of shredded cheddar cheese, chopped green onions, garlic powder, black pepper, and paprika. Stir everything together until the mixture is smooth and well combined, ensuring an inviting depth of flavor for your casserole.
Step 4: Incorporate the Potatoes and Kielbasa
Now, gently fold in the frozen diced hash browns into the creamy mixture. Once the potatoes are well coated, incorporate the browned kielbasa, ensuring every ingredient is mixed evenly. This will create a delicious blend of textures and flavors that will bake to perfection in your casserole.
Step 5: Assemble the Casserole
Carefully transfer the mixture into your prepared baking dish, spreading it out evenly. This is the foundation of your Kielbasa Sausage Cheesy Potato Casserole! Sprinkle the remaining cheese evenly over the top, and if you're using them, add any optional crunchy toppings like crushed cornflakes or Ritz crackers for a delightful finish.
Step 6: Bake to Golden Perfection
Place the baking dish in the preheated oven and bake uncovered for 45-50 minutes. You'll know it's done when the casserole is bubbling and the top is golden brown. This baking time allows all those comforting flavors to meld beautifully, resulting in an irresistible aroma wafting through your kitchen.
Step 7: Let it Rest Before Serving
Once baked, remove the casserole from the oven and allow it to cool for 5-10 minutes. This resting time helps the cheese set and makes serving much easier! Take a moment to appreciate the warm, cheesy goodness in your Kielbasa Sausage Cheesy Potato Casserole before diving in with family or friends.

Make Ahead Options
These Kielbasa Sausage Cheesy Potato Casserole is a fantastic recipe for those busy weeknights when time is limited! You can assemble the entire casserole up to 24 hours in advance and simply refrigerate it, making meal prep a breeze. Just follow the initial steps, and once you're ready to bake, allow for an extra 10-15 minutes of cooking time if the casserole is cold. If you'd like to prepare it even earlier, consider making it and freezing it uncovered for up to 3 months; wrap it tightly in foil, and thaw overnight in the refrigerator before baking. This way, you'll enjoy the same comforting flavors—just as delicious as when freshly made!

Kielbasa Sausage Cheesy Potato Casserole Recipe FAQs
What are the best potatoes to use for this casserole?
Absolutely go for frozen diced hash brown potatoes for an easy, no-thaw option! They provide the ideal texture and structure. If using fresh potatoes, shred or dice them finely and soak them in water to remove excess starch, which prevents them from becoming too gummy during cooking.
How should I store leftover Kielbasa Sausage Cheesy Potato Casserole?
Store any leftovers in an airtight container in the fridge for up to 4 days. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) for about 20 minutes, ensuring the cheese remains nice and gooey upon serving!
Can I freeze Kielbasa Sausage Cheesy Potato Casserole?
Very much so! Prepare the casserole without baking it, then wrap it tightly in aluminum foil and freeze for up to 3 months. When you’re ready to bake, thaw it in the fridge overnight, and add an extra 10-15 minutes to the baking time if it's still a bit cold when you put it in.
What should I do if my casserole is too watery?
If you find your casserole ends up watery, it could be due to excess moisture from the frozen hash browns or the soup. To troubleshoot, be sure to mix the ingredients thoroughly but don’t over-stir the potatoes. If you’re using fresh potatoes, make sure they are well-dried after soaking. You can also add a bit more cheese or crushed crackers as a topping to absorb moisture while baking.
Are there any dietary considerations for this recipe?
Definitely! If you have allergies, turkey kielbasa works as a lighter alternative to smoked kielbasa, and you can substitute Greek yogurt for sour cream. Always check ingredient labels for specific allergens, and be cautious when sharing with pets, as certain seasonings could be harmful to them.
Can I make this casserole ahead of time?
Yes! You can assemble your Kielbasa Sausage Cheesy Potato Casserole up to 24 hours in advance. Just cover it tightly and refrigerate until you’re ready to bake. If you put it directly in the oven from the fridge, be sure to add a few extra minutes to the cooking time for a perfectly baked result.
