Equipment

Ingredients

  • 1 pound ground Italian sausage
  • 1 cup diced white or yellow onion
  • 5 cloves garlic minced
  • ¼ cup red wine
  • 25 ounce jar spaghetti sauce
  • 16 ounces dry spaghetti noodles broken in half
  • 4 cups water
  • 15 ounce jar Alfredo sauce.
  • Grated Parmesan cheese

Instructions

  • Press sauté
  • When hot, add Italian sausage, and cook, stirring occasionally, until browned.
  • Drain grease from Italian sausage and return to the inner pot.
  • Add the onion, and cook, stirring regularly, until softened, about 2-3 minutes.
  • Stir in the garlic and cook, stirring regularly, for 30 seconds.
  • Pour in the wine and scrape up any browned bits.
  • Press cancel.
  • Add the spaghetti sauce, noodles, and water.
  • Close and lock the lid.
  • Turn the pressure release valve to sealing.
  • Press manual high pressure and adjust the cooking time to 5 minutes.
  • When cooking time finishes, let the pressure release for 5 minutes.
  • After 5 minutes, carefully turn the pressure release valve to venting to quickly release the remaining pressure.
  • Unlock and remove the lid.
  • Give the spaghetti a good stir. If the noodles aren't as soft as you would like, cover and let the spaghetti sit for a few minutes.
  • Stir in the Alfredo sauce until combined.
  • Serve topped with grated Parmesan cheese.

Notes

  • Italian sausage: Hot or mild ground Italian sausage will work.
  • Red wine: You can substitute beef broth if you prefer. If you use beef broth, I recommend using reduced-sodium broth.
  • Spaghetti sauce: The spaghetti sauce adds a lot of the flavor, so choose a sauce that you like. 
  • Alfredo sauce: I recommend choosing an Alfredo sauce that you like. 
  • Nutrition values are estimates.
