Stars of the Show: Main Ingredients in Kielbasa Sausage Cheesy Potato Casserole

• Kielbasa sausage – Smoked, savory, and full of depth, it infuses every bite with bold, meaty flavor.
• Potatoes – Diced and tender, they’re the creamy canvas for all that cheesy goodness.
• Onions – Sautéed until sweet and fragrant, they round out the dish with comforting aroma.
• Garlic – Just enough to wake up the richness with a sharp, savory kick.
• Sharp cheddar cheese – Melts beautifully into the sauce, offering sharp, tangy notes that balance the dish.
• Cheddar cheese soup – Adds velvety texture and a cheesy punch without the need for a roux.
• Heavy cream & chicken broth – Together, they create a rich, luscious base that keeps everything moist and decadent.

Let’s Make It: How to Whip Up This Kielbasa Sausage Cheesy Potato Casserole

Start by browning sliced kielbasa in a bit of water, coaxing out its deep smoky flavors. Once the water evaporates and the sausage caramelizes, toss in diced onions and garlic until they turn soft and aromatic.

Next, add the diced potatoes and pour in the broth, cream, soup, and seasonings. Let the mixture come to a gentle simmer—just until the edges start to bubble—then stir in the cheddar cheese for that signature creamy texture.

Pour everything into a baking dish and cover with foil. Bake until the potatoes are fork-tender, then uncover and return to the oven to create that golden, cheesy top layer. The final result? A bubbling, savory casserole with pockets of molten cheese and hearty bites of sausage in every spoonful.

Recipe Tips & Tasty Twists for Kielbasa Sausage Cheesy Potato Casserole

Want a spicier kick? Try using hot kielbasa or a dash of cayenne pepper for extra heat. If you’re after more vegetables, stir in some diced bell peppers or frozen peas with the potatoes for added color and texture.

For a smoky edge, substitute a portion of the cheddar cheese with smoked gouda. This casserole also adapts well to different sausages—Italian, turkey, or even chorizo can completely change the flavor profile without changing the cooking method.

Making it for a crowd? Double the recipe and bake in two dishes side by side—this one disappears fast!
