Kielbasa Sausage Cheesy Potato Casserole

Kielbasa sausage cheesy potato casserole is the dish I turn to when my family craves big comfort and nostalgia. Each forkful has everything I love: creamy cheddar sauce, smoky rounds of sausage, and pillowy russet potatoes. This is the ultimate bake to bring to potlucks or celebrations—people always ask for the recipe.

I first baked this after coming home from a snowy football game—my husband actually asked for seconds before I sat down at the table. It is that kind of guaranteed crowd pleaser.

Ingredients

• Russet potatoes: They hold their shape and soak up maximum flavor from the sauce Check for firm and unblemished skins
• Olive oil: Helps brown the kielbasa for more savory notes Choose extra virgin for fresh taste
• Smoked kielbasa sausage: Brings smoky depth and hearty texture Sliced evenly cooks best
• All purpose flour: Thickens the cheese sauce making it creamy and rich Sift ahead for even mixing
• Unsalted butter: Adds richness and helps with browning Go for high quality for better flavor
• Minced garlic: Infuses every bite with aromatic warmth Freshly minced has the biggest punch
• 2 percent milk: Keeps the sauce smooth and a touch lighter than whole milk
• Heavy cream: Balances with extra creaminess Choose fresh for the silkiest finish
• Ground cumin: Adds subtle earthy warmth Try to use freshly ground for best aroma
• Garlic powder: Boosts the garlicky flavor for deeper savoriness
• Salt: Seasons all ingredients evenly Use kosher for better control
• Cracked black pepper: Gives some gentle heat Crack fresh for best flavor
• Cheddar cheese soup: This shortcut makes the sauce supremely cheesy and smooth
• Shredded sharp cheddar cheese: Melts into a gooey topping Buy a block and shred for the best melt and flavor

Step-by-Step Instructions

Prep the Potatoes:

Peel and cube potatoes in even pieces so they cook consistently Boil them in well salted water until fork tender about seven minutes Drain well and arrange in a lightly sprayed nine by thirteen baking dish

Brown the Kielbasa:

Heat olive oil in a large skillet over medium heat Add sliced kielbasa and sauté until each piece is caramelized and deeply browned about five minutes Scatter over the potatoes

Start the Roux:

In the same pan melt butter and add the flour Whisk and cook gently until the mixture becomes pale gold and the raw flour taste disappears This happens in two to three minutes

Build the Sauce:

Add minced garlic and let it bloom for thirty seconds Pour in milk and cream whisking quickly to get out lumps Add cumin, garlic powder, salt, pepper, and cheddar cheese soup Cook and stir over medium heat until the mixture is thick and glossy This takes about three to four minutes

Add the Cheese:

Remove the pan from heat and stir in shredded sharp cheddar Let it melt fully so the sauce is rich and smooth

Combine and Bake:

Pour the cheese sauce evenly over the potatoes and kielbasa Use a spoon to help it seep into all the edges Bake uncovered at three hundred fifty degrees Fahrenheit for thirty minutes until bubbly and golden on top

Save

I am obsessed with the crust of bubbling cheese that forms on top Nothing beats the scoop when you serve it fresh from the oven to the table My kids fight over who gets the cheesiest corner

Storage Tips

Cool the casserole fully before storing Cut into squares and place in an airtight container for up to four days in the fridge For longer storage wrap tightly and freeze up to one month To reheat simply warm covered in the oven at a low temperature to keep the sauce creamy

Ingredient Substitutions

Golden potatoes or Yukon Golds can swap in for russets for a creamier texture If you want the dish lighter use turkey smoked sausage Swap cheddar cheese soup for nacho cheese or another melty cheese variety if that is what you have
