Ingredients
- Russet potatoes: about two pounds peeled and cubed for fluffy texture and soak up all that cheesy sauce Look for firm potatoes with no green spots
- Olive oil: adds richness and helps crisp the kielbasa Choose a good quality olive oil for best flavor
- Smoked kielbasa sausage: one pound sliced into rounds gives a smoky comforting taste Opt for kielbasa with a natural casing for the best snap
- Unsalted butter: four tablespoons builds the base of your roux Go with high quality butter for flavor
- All purpose flour: a quarter cup for thickening the cheese sauce Make sure your flour is fresh for smooth results
- Garlic: three cloves minced adds depth to the sauce Fresh garlic has more kick than jarred
- Two percent milk: one and a half cups gives the sauce creamy body Look for well chilled milk for freshness
- Heavy cream: half a cup for extra creaminess The richer the cream the silkier your sauce
- Ground cumin: half a teaspoon brings a subtle warmth and earthiness Use freshly ground for bold flavor
- Garlic powder: half a teaspoon enhances the garlic background Check your spice jar is not expired for the strongest taste
- Salt and cracked black pepper to taste: season everything just right Use freshly cracked pepper for a bigger punch
- Cheddar cheese soup: one can ten and a half ounces for cheesy thickness This shortcut adds smooth texture
- Shredded sharp cheddar cheese: two cups divided packs a tangy cheese punch Shred from a block for the smoothest melting
Step-by-Step Instructions
- Prep the Potatoes:
- Peel and cube the russet potatoes then place in a large pot of salted water Boil just until tender about seven to ten minutes Drain very well so there is no extra moisture then layer them evenly in a greased baking dish This prevents a watery casserole later
- Brown the Kielbasa:
- While potatoes cook heat up the olive oil in a large skillet over medium high Add the sliced kielbasa and let it sear and caramelize about five to seven minutes This step layers in that smoky flavor and irresistible edges Spread the cooked sausage over the potatoes
- Make the Cheese Sauce:
- Melt butter in that same skillet over medium whisk in the flour and let it cook for two minutes to build a flavorful roux Add the garlic and let it soften for another thirty seconds to unlock its aroma
- Build the Sauce:
- Slowly pour in the milk and heavy cream whisking constantly to avoid lumps Stir in cumin garlic powder salt and pepper plus the can of cheddar cheese soup Keep whisking and simmering three to four minutes until the sauce thickens
- Melt in the Cheese:
- Remove skillet from heat Stir in one and a half cups of shredded cheddar and keep stirring until everything is completely melted and silky smooth This is the magic moment when the sauce comes together
- Assemble and Bake:
- Pour the hot cheese sauce evenly over the potato and kielbasa mixture Top with the last half cup of shredded cheddar Pop the dish in the oven uncovered for thirty minutes until bubbling and the top turns golden
- Rest and Serve:
- Let the casserole rest for ten minutes out of the oven This lets the sauce settle so you get neat squares when serving

Cheddar cheese is my favorite ingredient here Its tanginess offers the perfect contrast to starchy potatoes and smoky kielbasa My son loves helping me shred the cheese and sneaks bits from the bowl every time
