Ingredients at a glance (5)
- 1 lb sweet Italian sausage, casings removed, browned and crumbled
- 12 oz medium conchiglie pasta shells
- 2 cups smoky roasted red pepper cream sauce
- 8 oz cream cheese, softened and cubed
- 2 cups shredded whole-milk mozzarella
Instructions
Layer and Go
- Brown the SausageIn a large skillet over medium-high heat, cook the sweet Italian sausage, breaking it into crumbles, until browned and cooked through, about 8 to 10 minutes. Drain excess fat if needed. Transfer the browned sausage to the bottom of the slow cooker.Look for The sausage is browned and sizzling, with no pink remaining.Safe temperature 160°F (71°C) internal temperature (ground meat)Tip Browning adds depth; don't skip this step for the best flavor.
- Add Pasta and SauceSpread the uncooked conchiglie pasta shells over the sausage in an even layer. Pour the smoky roasted red pepper cream sauce over the pasta, using a spatula to gently press the shells into the sauce so they are mostly submerged.Look for The pasta is coated in the red sauce, with some liquid visible around the edges.Tip Ensure the pasta is well coated to prevent sticking.
- Top with CheesesPlace the softened cream cheese cubes in the center of the slow cooker. Sprinkle the shredded mozzarella evenly over the top, covering the pasta and sausage mixture completely.Look for The top is covered with white cream cheese and mozzarella.Tip Soften the cream cheese beforehand for even melting.
After layering the browned sausage, pasta, sauce, and cheeses, the slow cooker should be filled with colorful layers: the sausage at the bottom, the pasta shells coated in red sauce, and the top covered with white cream cheese cubes and a snowy blanket of mozzarella. The aroma is already inviting, with the smoky red pepper and savory sausage mingling. This is the point where you set it and forget it—just cover and turn on low.
Slow-Cook to Creamy
- Slow Cook on LowCover the slow cooker and cook on low for 3 to 4 hours, until the pasta is tender and the sauce is bubbling. Stir gently once after 2 hours to incorporate the melted cheeses, then continue cooking uncovered for the last 30 minutes if the sauce seems too thin.Look for The sauce is bubbling at the edges and the cheese is melted and creamy.Tip Resist lifting the lid frequently; each peek adds cooking time.
- Check Pasta DonenessAfter 3 hours, test a pasta shell for doneness. It should be tender but still hold its shape. If the pasta is still firm, continue cooking in 15-minute increments, checking each time, until al dente.Look for The pasta is tender with a slight bite, not mushy.Tip Cooking times vary; start checking at the 3-hour mark.
After 2-3 hours, the slow cooker will be bubbling gently around the edges. The cheese will have melted into the sauce, and the pasta will be swelling as it absorbs the liquid. The kitchen will smell of roasted red peppers and garlic.
Stir gently to combine the cheeses, and check the pasta for tenderness. The sauce should be creamy and coating the shells, not watery. If it's too thin, leave the lid off for the last 30 minutes.
Serve and Savor
- Stir and ServeGently stir the pasta bake to distribute the creamy sauce and melted cheese. Let it rest for 5 minutes before serving to allow the sauce to thicken slightly. Spoon onto plates or into bowls, making sure each serving gets plenty of sausage and cheesy sauce.Look for The mixture is creamy and cohesive, with cheese stretching from the spoon.Tip For a golden top, broil the finished dish for 2-3 minutes if your slow cooker insert is broiler-safe.
At the end, the pasta bake is a bubbling, golden casserole with melted mozzarella stretching from every scoop. The sauce is thick and creamy, clinging to the shells and sausage. The aroma is rich and comforting.
Let it rest for a few minutes before serving to let the sauce set slightly. Spoon onto plates, making sure each serving gets a generous portion of sausage and cheesy sauce. The result is a hearty, satisfying meal that needs nothing more than a simple green salad.
Common mistakes
One common mistake is lifting the lid too often, which releases heat and extends cooking time. Another is using a pasta shape that's too small, which can turn mushy. If the sauce seems too thick, add a splash of broth or water, but do so sparingly.
Avoid overcooking, as the pasta can become soft and lose its shape. Also, be sure to brown the sausage thoroughly before adding to the slow cooker—this step adds essential flavor and ensures food safety.
How to tell it’s done
The pasta bake is done when the pasta is tender and has absorbed most of the sauce, and the cheese is melted and bubbly. The internal temperature of the sausage should reach 160°F (71°C) if you need to check. The dish should look creamy and cohesive, not soupy. If the sauce is too thin, let it cook uncovered for an additional 30 minutes to thicken. If the pasta is still hard, continue cooking in 15-minute increments until tender.
