Before you start

Before starting, remove the Italian sausage from its casings and crumble it into small pieces. Slice the pepperoni if it is not already sliced. Measure the cheese and have the sauce ready.

There is no need to pre-cook the meat or pasta; they will cook in the slow cooker. Make sure your slow cooker is clean and dry. Have a large spoon and serving plates ready for when the dish is done.

Ingredients at a glance (6)
  • 4 oz thick-cut cup-and-char pepperoni
  • 1 lb Italian sausage, casings removed
  • 12 oz rigatoni pasta
  • 24 oz roasted garlic tomato basil sauce
  • 2 cups shredded Italian four-cheese blend
  • 1/2 cup freshly grated Parmigiano-Reggiano

Instructions

Layer and Top

  1. Layer the Meat and Pasta
    Place the pepperoni slices and Italian sausage crumbles in the bottom of a 7-quart slow cooker. Spread them into an even layer. Add the rigatoni pasta directly over the meat. Pour the roasted garlic tomato basil sauce over the pasta, covering it as evenly as possible.
    Look for The slow cooker should be about half full, with the sauce just covering the pasta.
    Tip For even cooking, try to nestle the pasta into the sauce so it is mostly submerged.
  2. Top with Cheese
    Sprinkle the shredded Italian four-cheese blend evenly over the top of the sauce. Finish with the freshly grated Parmigiano-Reggiano, covering the surface completely.
    Look for The cheese forms a thick, even blanket over the sauce.
    Tip Grating the Parmesan fresh gives the best melt and flavor.

At the end of this phase, the slow cooker contains a neat stack: meat on the bottom, pasta in the middle, sauce covering it, and a thick layer of cheese on top. The cheese should completely cover the sauce so that it melts into a golden crust. The ingredients are raw, but the visual appeal is already there.

Slow Cook

  1. Slow Cook
    Cover the slow cooker and cook on low for 4 hours, or until the pasta is tender and the sausage is cooked through. Do not stir during cooking unless needed, as stirring can break up the pasta and make it mushy.
    Look for After 4 hours, the sauce should be bubbling gently around the edges and the cheese melted and golden.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip If the sauce looks too thick, add a splash of water or broth, but avoid over-stirring.

After 4 hours on low, the slow cooker is bubbling gently around the edges. The cheese has melted and started to brown, and the sauce is thick and fragrant.

The kitchen smells of garlic, tomato, and herbs. The pasta is tender, and the sausage is cooked through. Do not stir; just peek to check the consistency.

Rest and Serve

  1. Finish and Serve
    Once the pasta is tender and the sausage reaches 160°F (71°C), turn off the slow cooker. Let the dish rest for 5 minutes before serving. Use a large spoon to scoop the cheesy pasta onto plates, making sure to get a good amount of the meat and sauce in each serving.
    Look for The cheese should stretch as you scoop, and the pasta should be al dente.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Serve directly from the slow cooker to keep everything warm.

After resting, the dish is ready to serve. The cheese stretches as you scoop, and the pasta is coated in a rich, meaty sauce. The pepperoni has curled and crisped slightly, and the Parmesan adds a nutty finish. Each serving is a hearty portion that fills the plate.

Common mistakes

A common mistake is stirring the pasta during cooking, which can break the noodles and create a mushy texture. Another issue is using too much sauce, which can make the dish watery. Stick to the amounts listed.

If the sauce seems too thick, add a little water, but do not add extra liquid unless needed. Also, avoid opening the slow cooker lid too often, as that lets out heat and extends the cooking time.

How to tell it’s done

The dish is done when the pasta is tender but still has a slight bite, and the sausage is cooked through with no pink remaining. The internal temperature of the sausage should reach 160°F (71°C).

The cheese on top will be melted and starting to brown in spots, and the sauce will be bubbling around the edges. Let the dish rest for a few minutes before serving to allow the flavors to meld and the cheese to set slightly.

  • Ground meat: 160°F (71°C) in the thickest part
