Ingredients

Why this recipe works

The slow cooker gently simmers the pasta and kielbasa together, allowing the flavors to meld and the pasta to absorb the creamy sauce. The low, even heat prevents the dairy from curdling and gives the cheese time to melt into a silky sauce. The Boursin, with its garlic and herb notes, infuses the entire dish with flavor without any extra seasoning.

Using smoked kielbasa means the meat is already fully cooked, so it only needs to heat through and caramelize slightly in the sauce. This makes the recipe incredibly forgiving and nearly impossible to overcook.

The combination of the smoky sausage, sweet roasted red pepper, and rich, creamy cheese creates a balanced, deeply satisfying flavor profile that will please the whole family.

Notes and substitutions

Choose a good-quality smoked kielbasa for the best flavor. Look for one that is plump and juicy, with a nice smoky aroma. Slice it diagonally into thick medallions so they hold their shape during cooking and provide a hearty bite. The pasta shells should be medium-sized so they cook evenly and capture the sauce in their curves.

The roasted red pepper cream sauce can be homemade or store-bought. If using store-bought, look for a brand with a rich, roasted pepper flavor and a creamy consistency.

Boursin cheese is a soft, spreadable cheese flavored with garlic and herbs; it melts beautifully and adds a luxurious texture. Fontina is a good melting cheese with a nutty, buttery taste, but mozzarella or provolone can be substituted.

• smoked kielbasa: Smoked turkey kielbasa or andouille sausage for a different smoky flavor.
• conchiglie pasta shells: Any short pasta like rigatoni, penne, or cavatappi works well.
• roasted red pepper cream sauce: Use a jarred roasted red pepper sauce or make a quick sauce from blended roasted peppers and cream.
• fontina cheese: Substitute with shredded mozzarella or provolone for similar meltability.
