Provolone Kielbasa Red Pepper Shells: Easy Crockpot Dinner Step-by-step instructions

Before you start

Before you start, slice the kielbasa into medallions—about 1/2-inch thick. Have the pasta shells, red pepper sauce, ricotta, and shredded provolone ready to go. No need to cook the pasta or brown the sausage; everything goes into the slow cooker raw.

If your slow cooker is smaller than 6 quarts, you may need to adjust the quantities or cook in batches. Make sure the slow cooker is clean and dry before adding the ingredients.

Instructions

Layer and Top

1. 1Layer the Ingredients
   Place the sliced kielbasa medallions in the bottom of a 6-quart slow cooker. Spread them into an even layer. Add the uncooked pasta shells over the kielbasa. Pour the smoky roasted red pepper cream sauce over the pasta, making sure the sauce covers the shells as much as possible. Use a spoon to gently press the shells into the sauce so they are mostly submerged.
   Look for The kielbasa is in an even layer, the pasta is spread over it, and the sauce coats the shells.
   Tip If the sauce is thick, you can add a splash of water or broth to help the pasta cook, but the video doesn't show that.
2. 2Add the Cheeses
   Spoon dollops of whole-milk ricotta over the top of the sauce. Spread the ricotta gently with the back of a spoon, leaving some areas bare. Sprinkle the shredded provolone evenly over the entire surface, covering the ricotta and the pasta. Do not stir the mixture—leave the layers as they are.
   Look for The top is covered with white ricotta dollops and a blanket of shredded provolone.
   Tip Resist the urge to stir; the layers will meld during cooking.

At the end of this phase, you'll have a neat layer of kielbasa at the bottom, pasta shells on top, and the red pepper sauce poured over. The ricotta dollops and shredded provolone sit on top like a blanket. The ingredients are not stirred, so the layers are distinct. The sauce should coat the pasta, and the cheese should cover the surface. This is the 'dump it in' stage—everything is ready for the slow cooker.

Slow Cook and Simmer

3. 3Slow Cook the Casserole
   Cover the slow cooker with its lid. Cook on LOW for 4 hours, or on HIGH for 2 hours, until the pasta is tender and the sauce is bubbling around the edges. Do not lift the lid during the first 3 hours of cooking, as this releases heat and slows the cooking process.
   Look for The sauce is bubbling gently around the edges, and the aroma of smoked kielbasa and cheese fills the kitchen.
   Tip If the pasta still seems firm after the recommended time, continue cooking in 15-minute increments.
4. 4Check for Doneness
   After the cooking time is up, uncover the slow cooker. Check that the pasta shells are tender by tasting one. The sauce should be creamy and slightly thickened, and the cheese should be melted and lightly browned in spots. If the pasta is still firm, cover and cook for another 15 to 30 minutes.
   Look for The pasta is al dente, the sauce is creamy, and the cheese is fully melted.
   Tip If the sauce seems too thin, let it sit uncovered for 10 minutes to thicken slightly.

After several hours, the slow cooker will be bubbling gently around the edges. The aroma of smoked sausage and cheese will fill the kitchen. The pasta should be tender, and the sauce will have thickened slightly. The cheese will be melted and may be lightly browned in spots. The casserole should look creamy and cohesive, with the kielbasa and shells visible in the sauce. If the pasta is still firm, continue cooking.

Serve and Enjoy

5. 5Serve the Casserole
   Using a large spoon, gently stir the casserole to combine the layers. Spoon the hot pasta and kielbasa onto a serving plate or into bowls. Serve immediately, making sure each portion gets some of the melted cheese and sauce.
   Look for The casserole is steaming, with cheese stretching as you spoon it out.
   Tip For a nice presentation, serve on a white plate to show off the creamy red sauce and browned cheese.

The finished dish is a bubbling, cheesy casserole with a rich red-orange sauce. The kielbasa coins are caramelized at the edges, and the pasta shells are coated in creamy sauce. The ricotta and provolone have melded into a luscious, stretchy topping.

When you spoon it out, the cheese pulls in long strands. It's steaming hot, so let it rest a few minutes before serving. The texture is creamy, with a slight bite from the pasta and a satisfying chew from the sausage.

Common mistakes

One common mistake is lifting the lid too often to check on the pasta—this releases heat and extends the cooking time. Trust the timer and resist the urge to peek. Another mistake is using a pasta shape that's too small, which can turn to mush.

Stick with medium or large shells. Also, don't skip the ricotta dollops—they add creaminess that balances the smoky sauce. Finally, be sure to use a slow cooker that's the right size; if it's too full, the pasta may not cook evenly.

How to tell it’s done

The dish is done when the pasta is tender with a slight bite, and the sauce is bubbling around the edges. The cheese should be fully melted and lightly browned in spots. To check, taste a pasta shell—it should be cooked through but not mushy.

The internal temperature of the casserole should be at least 165°F (74°C) if you want to be precise, though the kielbasa is already cooked. Let it rest for 5 minutes before serving to allow the sauce to set slightly.
