Crockpot Boursin Sausage Pasta Shells Step-by-step instructions

Before you start

Before starting, remove the sausage from the refrigerator and let it sit at room temperature for up to 30 minutes. Heat a large skillet over medium-high heat. Have your slow cooker insert ready.

Measure the sauce and shred the fontina if not pre-shredded. Keep the Boursin in the fridge until ready to use. No need to pre-cook the pasta; it will cook in the sauce. Ensure the slow cooker is clean and dry.

Instructions

Phase 1: Brown and Layer

1. 1Brown the Sausage
   Heat a large skillet over medium-high heat. Add the sausage in crumbles and cook, breaking it up with a wooden spoon, until browned and cooked through, about 8 minutes. Drain any excess fat.
   Look for The sausage should be deeply browned and no longer pink inside.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Browning adds flavor, but ensure the sausage reaches 160°F (71°C) before moving on.
2. 2Layer in the Crockpot
   Place the browned sausage crumbles evenly in the bottom of a 6-quart slow cooker.
   Look for The sausage forms an even layer covering the bottom.
   Tip No need to grease the insert; the sausage provides enough moisture.

The sausage should be browned and crumbly, with no pink remaining. The bottom of the slow cooker is covered with a savory layer of meat. The kitchen smells of fennel and pork. The pasta and sauce are added, and the top is scattered with cheese. Everything is ready for the slow cook.

Phase 2: The Slow Simmer

3. 3Add Pasta and Sauce
   Add the uncooked conchiglie pasta shells over the sausage, then pour the smoky roasted red pepper cream sauce over the pasta, making sure the shells are mostly submerged.
   Look for The sauce should coat the shells; some shells may peek out.
   Tip Stir gently to coat the pasta, but keep it in an even layer.
4. 4Top with Cheeses
   Place the Boursin wheel in the center of the slow cooker, then scatter the shredded fontina over the top.
   Look for The Boursin sits like a creamy island, surrounded by fontina.
   Tip Do not stir after adding the cheeses; they will melt into the sauce during cooking.

After 4 hours on low, the sauce is bubbling at the edges, and the cheese has melted into a golden, creamy blanket.

The pasta is tender, and the whole dish is fragrant with garlic, herbs, and roasted red peppers. The sauce has thickened, and the shells are coated. A spoonful should hold its shape.

Phase 3: Stir and Serve

5. 5Slow Cook Until Bubbling
   Cover and cook on low for 4 hours, or until the pasta is tender and the sauce is bubbling and creamy. Do not lift the lid during the first 3 hours.
   Look for The sauce will be thick and bubbling at the edges, and the kitchen will smell of garlic and herbs.
   Tip Cooking on low prevents the pasta from becoming mushy.
6. 6Stir and Serve
   Stir the pasta gently to combine the melted Boursin and fontina into the sauce. Serve hot, straight from the slow cooker.
   Look for The sauce is silky and coats each shell; the cheese stretches when lifted.
   Tip The pasta will continue to absorb sauce as it sits, so serve promptly.

After stirring, the sauce is silky and clings to every shell. The Boursin and fontina are fully incorporated, creating a rich, creamy texture. The dish is steaming and ready to plate. A spoonful lifts with a satisfying cheese pull. The flavors are balanced—savory, slightly sweet, and smoky.

Common mistakes

The most common mistake is lifting the lid too early. This releases steam and drops the temperature, which can leave the pasta undercooked. Resist the urge to stir during the first 3 hours. Another mistake is using a watery sauce; it won't thicken enough, and the pasta will be soupy.

Choose a thick, creamy sauce. Overcooking is also a risk: on high, the pasta may become mushy. Stick to low and check at the 3.5-hour mark. Finally, don't skip browning the sausage—it adds essential flavor.

How to tell it’s done

The dish is done when the pasta is tender but still holds its shape, and the sauce is bubbling around the edges. The Boursin and fontina should be fully melted, and the sauce should be creamy and slightly thickened.

To check the sausage, it should have reached 160°F (71°C) during the browning step; if you're unsure, use a thermometer. The pasta should be al dente, not mushy. Let the dish rest for 5 minutes before serving to allow the sauce to settle.
