Ingredients

Why this recipe works

The slow cooker creates a gentle, even heat that allows the flavors to meld and deepen without any effort. The kielbasa releases its smoky juices into the sauce, while the Boursin melts into a velvety cream that coats every piece of pasta. The result is a rich, complex sauce that tastes like it simmered all day, even though you only spent ten minutes on prep. This method is foolproof: no stirring, no watching, no worrying about burning. Just set it and forget it.

Using a whole wheel of Boursin cheese is the secret to this dish's luxurious texture. Unlike shredded cheese, which can sometimes clump or separate, Boursin melts into a smooth, creamy sauce that evenly coats the pasta. The garlic and herbs in the Boursin also infuse the entire dish with flavor, so you don't need to add extra seasonings. Combined with the fontina, which adds a stretchy, melty finish, this dish has the perfect balance of creaminess and cheese pull.

Notes and substitutions

Choose a good-quality marinara sauce for this recipe, as it's a major flavor component. Look for one with a short ingredient list and no added sugar. If you prefer a spicier dish, you can use arrabbiata or add a pinch of red pepper flakes.

The kielbasa should be fully cooked smoked sausage, not raw. The ziti is added dry, so it absorbs the sauce and cooks in the slow cooker. Don't worry if the pasta isn't completely submerged at first; it will soften as it cooks.

The Boursin cheese is the star of this dish, so don't substitute it with a plain cream cheese unless you add extra herbs and garlic. The fontina can be replaced with provolone or mozzarella, but fontina has a nutty flavor and excellent melting properties that really elevate the dish.

If you don't have a 6-quart slow cooker, you can use a 4-quart, but you may need to reduce the amount of pasta slightly. The cooking time may also vary, so check for doneness at the 2.5-hour mark.
