  • Instant Pot or other Electric Pressure Cooker (6 quart or 8 quart)


  • 2 teaspoons olive oil
  • 1 pound mild Italian sausage
  • 1 yellow onion diced
  • 1 red onion diced
  • 1 red bell pepper chopped
  • 1 teaspoon Italian seasoning
  • a pinch or two of salt and pepper
  • 4 1/2 cups chicken stock
  • 15 ounces canned diced tomatoes
  • 1 pound Rigatoni pasta
  • 1/2 cup freshly grated Parmesan cheese optional
  • chopped fresh parsley for serving optional


  • Set the Instant Pot to saute mode and add the olive oil.
  • Add the Italian sausage (casings removed) to the Instant Pot and break the sausage up into small pieces as it browns.
  • Add the diced onions and chopped bell peppers, along with the Italian seasoning, salt and pepper.
  • Stir everything together and let the veggies soften while the sausage browns.
  • Remove the sausage and veggies to a plate and add a splash of chicken stock to deglaze the pan. Scrape up all the caramelized bits - this will help you avoid the dreaded burn notice while pressure cooking.
  • Add about 2 cups of the stock to the Instant Pot and cancel the saute mode.
  • Add about half the noodles gently into the stock, along with half the diced tomatoes and then half the meat/veggie mixture.
  • Add the rest of the stock, and then gently add the rest of the noodles, the rest of the tomatoes, and then the rest of the meat/veggie mixture.
  • Don't stir. Just make sure the noodles are completely submerged in the liquid.
  • Add the lid to the Instant Pot and set the valve to sealing. Set the Instant Pot to cook on High Pressure for 7 minutes (the Instant Pot will take about 8 minutes to come to full pressure before the 7-minute cooking time begins).
  • Once the Instant Pot has finished the 7-minute cooking time, release the pressure manually by moving the valve to venting. It's best to do this under a hood fan if you have one in your kitchen, and by using a long-handled kitchen tool to move the valve (to prevent burning yourself).
  • Once the pressure has released completely, remove the lid immediately.
  • Stir the noodles and the sauce, helping the noodles separate if any are clumped together. As you toss a meaty sauce will form around the pasta. You can add the parmesan cheese at this stage too, or simply serve the pasta with parmesan cheese on top.
  • Serve the pasta immediately in its sauce with a sprinkling of parmesan cheese and some chopped fresh herbs (optional).
