  • 4 cups uncooked short pasta, such as penne or fusilli
  • 2 tablespoons butter
  • 2 tablespoons all-purpose flour
  • 2 1/2 cups milk
  • 1 cup sour cream
  • 2 tablespoons Dijon mustard
  • 1 teaspoon garlic powder
  • 1 (16 oz) jar sauerkraut, rinsed and well-drained
  • 1 1/2 lbs smoked Polish sausage or kielbasa, sliced 1/2-inch thick
  • 3 cups Swiss cheese, grated and divided
  • 4 green onions, chopped
  • Kosher salt and freshly ground black pepper, to taste


Step 1: Cook the Pasta

  1. Boil Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions until al dente. Drain and set aside.

Step 2: Prepare the Sauce

  1. Melt Butter: In a large saucepan, melt the butter over medium heat.
  2. Make Roux: Add the flour to the melted butter and whisk continuously for about 1-2 minutes to form a roux. It should be slightly golden but not browned.
  3. Add Milk: Slowly pour in the milk, whisking constantly to avoid lumps. Continue to cook and whisk until the mixture thickens and comes to a simmer, about 5-7 minutes.
  4. Add Sour Cream and Mustard: Stir in the sour cream, Dijon mustard, and garlic powder until well combined.
  5. Season: Season the sauce with kosher salt and freshly ground black pepper to taste.

Step 3: Assemble the Casserole

  1. Preheat Oven: Preheat your oven to 350°F (175°C).
  2. Combine Ingredients: In a large mixing bowl, combine the cooked pasta, sauce, sauerkraut, sliced sausage, and half of the grated Swiss cheese. Mix well to combine.
  3. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish and spread it out evenly.
  4. Top with Cheese: Sprinkle the remaining Swiss cheese and chopped green onions over the top of the casserole.

Step 4: Bake the Casserole

  1. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the casserole is bubbly and the cheese is melted and golden brown.
  2. Cool Slightly: Let the casserole cool for a few minutes before serving.

Cook Notes and Variations

  • Cheese Options: You can use Gruyère or a mix of Swiss and mozzarella cheese for a different flavor profile.
  • Vegetable Additions: Add sautéed mushrooms or bell peppers for extra vegetables and flavor.
  • Spicy Version: Add a pinch of red pepper flakes or a chopped jalapeño for a spicy kick.
  • Breadcrumb Topping: Sprinkle breadcrumbs mixed with a bit of melted butter on top before baking for a crunchy crust.

Keto and Low-Carb Versions

Keto Version:

  • Pasta Substitute: Use low-carb pasta or spiralized zucchini noodles (zoodles) instead of traditional pasta.
  • Flour Substitute: Use almond flour or coconut flour for the roux.
  • Milk Substitute: Use heavy cream instead of milk for a richer, low-carb sauce.

Low-Carb Version:
