Ingredients

Why this recipe works

The slow cooker does all the work: by cooking the pasta directly in the sauce, the shells absorb the smoky red pepper cream as they soften, creating a cohesive, saucy dish without a separate pot of boiling water. The low, gentle heat melts the cream cheese and mozzarella into a silky sauce that clings to every bite, while the browned sausage adds savory depth. This method eliminates the need to watch a pot, making it truly a dump-and-forget meal.

The key to success lies in the layering and the low-and-slow cooking. Placing the pasta at the bottom ensures it stays submerged in the sauce and cooks evenly. The cream cheese, added in a block, melts slowly and creates a luxurious texture without curdling.

The mozzarella on top forms a golden, bubbly crust that's irresistible. This recipe is designed for flexibility—you can adjust the sauce-to-pasta ratio to your liking, and it's forgiving enough for even the busiest cooks.

Notes and substitutions

Use a good-quality smoky roasted red pepper cream sauce for the best flavor. You can find it in the pasta sauce aisle or make your own by blending roasted red peppers with heavy cream and a pinch of smoked paprika. The sauce should be thick enough to coat the pasta but with enough liquid to cook it. If it seems too thick, add a splash of chicken broth or water. Sweet Italian sausage is traditional, but hot Italian sausage adds a nice kick.

This recipe calls for uncooked pasta shells, which is what makes it so easy. The pasta absorbs the sauce as it cooks, so don't pre-cook it. Medium conchiglie work perfectly because their shape holds the sauce and sausage.

If you prefer a different shape, choose something sturdy like rigatoni or penne. The slow cooker size matters: a 7-quart model is ideal for this quantity. If using a smaller slow cooker, reduce the ingredients proportionally.

• sweet Italian sausage: Use hot Italian sausage for a spicy kick, or ground pork seasoned with fennel, salt, and pepper.
• conchiglie pasta: Substitute with any short pasta like penne, rigatoni, or cavatappi. Adjust cooking time if using a smaller shape.
• smoky roasted red pepper cream sauce: Use a jarred roasted red pepper sauce or make a quick version by blending roasted red peppers with heavy cream and smoked paprika.
