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

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

Ingredients

01 900 g Russet potatoes, peeled and cubed
02 15 ml olive oil
03 450 g smoked kielbasa sausage, sliced into rounds
04 60 g unsalted butter
05 30 g all-purpose flour
06 3 cloves garlic, minced
07 360 ml 2% milk
08 120 ml heavy cream
09 0.5 g ground cumin
10 0.5 g garlic powder
11 Salt and cracked black pepper, to taste
12 300 g canned cheddar cheese soup
13 200 g shredded sharp cheddar cheese, divided

Instructions

Step 01

Set oven to 175°C. Lightly grease a 33x23 cm baking dish.

Step 02

Place cubed potatoes in a large pot with salted water. Bring to a boil and simmer until fork-tender, about 7–10 minutes. Drain thoroughly and arrange evenly in the prepared baking dish.

Step 03

While potatoes cook, heat olive oil in a large skillet over medium-high heat. Add sliced kielbasa and cook until browned and caramelized, about 5–7 minutes. Distribute the sausage over the potatoes.

Step 04

In the same skillet, melt butter over medium heat. Whisk in flour to form a roux and cook for 2 minutes, stirring constantly.

Step 05

Add minced garlic and cook 30 seconds. Gradually whisk in milk and heavy cream until smooth. Stir in cumin, garlic powder, salt, pepper, and cheddar cheese soup. Cook, whisking frequently, until thickened, 3–4 minutes. Remove from heat and incorporate 150 g shredded cheddar until the sauce is smooth.

Step 06

Pour the cheese sauce evenly over the potatoes and kielbasa. Sprinkle the remaining 50 g cheddar cheese on top.

Step 07

Bake uncovered for 30 minutes, until the sauce is bubbling and top is golden. Rest for 10 minutes before serving to allow the sauce to set.

Notes

  1. For the smoothest cheese sauce, shred cheddar from a block; pre-shredded cheese may result in a grainy texture.
  2. Letting the dish rest for 10 minutes after baking aids in setting the sauce and easier portioning.
  3. Yukon Gold potatoes can be substituted for a creamier result, and alternative sausages or a breadcrumb topping can be used for variations.
