Last week, my youngest had a soccer game that ran way longer than expected. By the time we got home, everyone was starving, including me. I needed dinner on the table fast—but it had to be comforting too, something warm and filling after standing in the wind all afternoon.

⁠

That’s when this Kielbasa Sausage Cheesy Potato Casserole came to the rescue. It’s one of those dishes I turn to when time is tight, ingredients are limited, and I just want something hearty that won’t end in complaints at the dinner table.

I’ve made this casserole so many times, I could probably do it with my eyes closed. It started as a fridge-clean-out meal, honestly. I had a leftover pack of kielbasa, a half-used bag of sharp cheddar, and a few sad potatoes hanging out in the pantry. The first time I threw it together, I wasn’t expecting it to be a hit but it was. And now it’s in regular rotation, especially when we have guests or busy weeknights.

My husband always sneaks a second serving, and my kids barely look up from their plates while eating it (a rare moment of silence I completely treasure). It’s the kind of recipe you’ll keep around, the kind you share with your neighbor when they ask, “What smells so good?”

Short Description

A hearty and comforting casserole loaded with tender potatoes, smoky kielbasa, and a creamy, cheesy sauce—easy to make and even easier to love.

Key Ingredients

3 cups russet potatoes, peeled and cubed
1 tablespoon olive oil
1 pound smoked kielbasa sausage, sliced
¼ cup all-purpose flour
¼ cup unsalted butter
2 teaspoons minced garlic
1½ cups 2% milk
½ cup heavy cream
½ teaspoon ground cumin
½ teaspoon garlic powder
1 teaspoon salt
½ teaspoon cracked black pepper
1 can (284ml) cheddar cheese soup
2 cups shredded sharp cheddar cheese

Tools Needed

Large skillet
Medium pot
9×13-inch baking dish
Wooden spoon or silicone spatula
Strainer
Whisk

Cooking Instructions

Step 1: Prep and Boil the Potatoes
Preheat oven to 350°F and spray a 9×13-inch baking dish with cooking spray. In a medium pot, boil cubed potatoes for about 7 minutes, or until fork-tender but not mushy. Drain and transfer to the prepared dish.

Step 2: Sauté the Kielbasa
In a skillet, heat olive oil over medium heat. Add the sliced kielbasa and cook for 5 minutes, stirring occasionally, until nicely browned. Scatter them over the potatoes in the baking dish.

Step 3: Make the Cheese Sauce Base
Using the same skillet (no need to wash it!), melt butter and whisk in the flour. Cook for 1–2 minutes until the flour disappears and forms a smooth roux.

Step 4: Add the Liquids and Seasonings
Whisk in minced garlic, 2% milk, heavy cream, cumin, garlic powder, salt, pepper, and cheddar cheese soup. Stir constantly over medium heat for 3–4 minutes until the mixture begins to thicken.

Step 5: Stir in the Cheese
Remove skillet from heat. Add shredded sharp cheddar cheese and stir until fully melted and creamy.

Step 6: Assemble and Bake
Pour the cheese sauce evenly over the potato and kielbasa mixture. Gently toss to coat everything. Bake uncovered for 30 minutes, or until bubbling and golden on top.

Mistakes to Avoid & Solutions

Overboiling the Potatoes: If they’re too soft, they’ll turn mushy in the oven.
Solution: Boil just until fork-tender—7 minutes is usually enough.

Cheese Sauce Too Runny: Skipping the flour-butter roux or undercooking it will cause a watery sauce.
Solution: Cook the roux fully before adding liquids. Stir constantly to thicken.

Cheese Not Melting Properly: Adding cheese on high heat can cause it to clump.
Solution: Remove skillet from heat before stirring in the shredded cheese.

Dry Casserole: If you use low-fat milk or less cheese, the sauce may be too thin.
Solution: Stick with the recipe’s mix of 2% milk and heavy cream for best texture.

Uneven Flavor: Forgetting to season will leave the dish bland.

Recipe Variations

Swap half the potatoes for cauliflower or broccoli florets. Add sautéed onions and bell peppers. Follow the same steps, just slightly reduce cooking time as veggies cook quicker.

Southwest Twist
Use spicy smoked sausage, add ½ cup of corn and a drained can of black beans. Season the sauce with a pinch of chili powder and lime zest.

Breakfast Casserole Version
Use breakfast sausage instead of kielbasa, and stir in scrambled eggs before baking. Top with extra cheese and bake the same way.

Low-Carb Option
Replace potatoes with steamed cauliflower florets. Use full-fat dairy for creaminess. Bake until golden.

Creamy Ranch Version
Add a packet of dry ranch seasoning to the cheese sauce. Swap cheddar soup with cream of chicken for a milder flavor.
