There are some casseroles that feel like a warm hug from a church potluck, and this Smoked Sausage & Cheesy Potato Casserole is exactly that. It is creamy, cheesy, and deeply satisfying, with tender potatoes, savory smoked sausage, and a golden, bubbly cheese topping that makes every bite irresistible. The best part? It comes together with simple ingredients and about fifteen minutes of prep.

What I love most about this recipe is how effortlessly it delivers on comfort. The smoked sausage infuses the potatoes with a rich, smoky flavor, while the creamy sauce and melted cheddar tie everything together in one cozy, scoopable dish. It is the kind of meal that makes busy weeknights feel a little more special and turns a simple dinner into something everyone at the table will love.

It is perfect for potlucks, holiday brunches, game days, or any time you need a hearty, crowd-pleasing casserole that feeds a crowd. Serve it with a crisp salad and some crusty bread, and watch it disappear before you can even sit down.

Ingredients

2 pounds Yukon Gold or red potatoes, thinly sliced (about 1/8-inch thick)
1 pound smoked sausage or kielbasa, sliced into rounds
2 cups shredded sharp cheddar cheese, divided
1 can (10.5 ounces) cream of mushroom or cream of chicken soup
1 cup sour cream
1/2 cup whole milk
1 small yellow onion, diced
2 cloves garlic, minced
1 teaspoon smoked paprika
1/2 teaspoon salt
1/2 teaspoon black pepper

Optional: 1/2 cup crushed butter crackers or panko breadcrumbs mixed with 2 tablespoons melted butter for topping.

Directions

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
In a large bowl, whisk together the cream soup, sour cream, milk, garlic, smoked paprika, salt, and pepper until smooth.
Add the sliced potatoes, smoked sausage, diced onion, and 1 cup of the shredded cheddar to the bowl. Stir until everything is evenly coated.
Pour the mixture into the prepared baking dish and spread it into an even layer.
Cover tightly with aluminum foil and bake for 45 minutes.
Remove the foil and sprinkle the remaining 1 cup of cheddar over the top. If using cracker topping, scatter it over the cheese.
Bake uncovered for another 20 to 25 minutes, until the potatoes are fork-tender and the top is golden and bubbly.
Let rest for 10 minutes before serving.

Variations

Spicy Sausage Casserole: Use andouille or hot Italian sausage and add a pinch of red pepper flakes.
Broccoli Cheddar Version: Add 2 cups of steamed broccoli florets to the mixture.
Bacon Lover’s: Sprinkle cooked, crumbled bacon over the top before baking.
Cheesy Hash Brown Version:Substitute frozen diced hash browns for the sliced potatoes.
Different Cheese: Try Gruyère, Monterey Jack, or a Mexican cheese blend.
Gluten-Free: Use gluten-free cream soup and gluten-free cracker topping.

Expert Tips

Slice potatoes evenly: Thin, uniform slices ensure even cooking. A mandoline makes this quick and easy.
Don’t skip the foil: Covering the dish traps steam and helps the potatoes cook through without drying out.
Use freshly shredded cheese: It melts more smoothly than pre-shredded, which contains anti-caking agents.
Add cheese at the end: Reserving some cheddar for the top gives you that gooey, golden finish.
Let it rest: Resting allows the casserole to set and makes serving easier.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or in a 350°F oven with a splash of milk or broth to loosen. This casserole freezes well for up to 3 months. Thaw overnight in the refrigerator before reheating.
