Crank Up the Oven
Set your oven to a toasty 350 degrees Fahrenheit. Let it warm up while you prepare the delicious ingredients.
Prep the Baking Dish
Grab a 9 x 13 inch baking dish and give it a generous spray of non-stick cooking spray. This will prevent any sticky situations later.
Boil the Potatoes
Fill a medium pot with water and toss in the cubed potatoes. Bring the water to a rolling boil and cook the potatoes until they’re tender but not mushy, about 7 minutes.
Drain the potatoes and spread them evenly in the prepared baking dish.
Sizzle the Kielbasa
Heat olive oil in a frying pan over medium heat.
Toss in the kielbasa sausage pieces and cook until they develop a beautiful golden-brown color, around 5 minutes. Transfer the sausage to the baking dish with the potatoes.
Create the Flour Base
In the same pan, melt butter and sprinkle in the all-purpose flour. Cook the mixture until it loses its raw, white appearance, indicating the flour is fully cooked.
Build the Creamy Sauce
Add minced garlic to the pan and cook briefly. Then pour in:
Stir continuously and let the sauce simmer and thicken for 3-4 minutes.
Melt the Cheese
Remove the pan from heat and stir in the shredded cheddar cheese until it melts completely and blends into a smooth, velvety sauce.
Combine and Coat
Pour the luscious cheese sauce over the potatoes and sausage, making sure every morsel gets a delicious coating.
Bake to Perfection
Slide the baking dish into the preheated oven and bake for 30 minutes. You’ll know it’s ready when the top turns a gorgeous golden brown and the sauce starts bubbling with excitement.

Kielbasa sausage cheesy potato casserole offers hearty satisfaction, with smoky sausage tucked into creamy potatoes and cheese for a rustic, filling dish everyone will love.
Ingredients
- 1 pound smoked kielbasa sausage (sliced into bite-size pieces)
- 3 cups russet potatoes (peeled and cubed)
- 2 cups shredded sharp cheddar cheese
- 1 can (284 ml) cheddar cheese soup
- 1 1/2 cups 2% milk
- 1/2 cup 33% heavy cream
- 1/4 cup unsalted butter
- 1/4 cup all-purpose flour
- 1 tbsp olive oil
- 2 tsp minced garlic
- 1 tsp salt
- 1/2 tsp ground cumin
- 1/2 tsp garlic powder
- 1/2 tsp cracked black pepper
Instructions
- Preheat the oven to 350°F, creating an ideal environment for a hearty casserole.
- Generously spray a 9 x 13 inch baking dish with non-stick cooking spray to prevent sticking.

- Bake in the preheated oven for 30 minutes, watching for a golden-brown top and bubbling sauce edges.
Notes
- Choose waxy potatoes like Yukon Gold or red potatoes for a creamy, firm texture that holds up well during baking.

- Replace cheddar cheese soup with homemade cheese sauce or use a blend of cheeses like Gruyère and sharp cheddar for enhanced depth of flavor.
