Ingredients

  • 1 tablespoon olive oil
  • 1 pound bulk Italian Sausage
  • salt and pepper to taste
  • 1 teaspoon Italian seasoning
  • 1 small onion, peeled and chopped
  • 4 sweet peppers, cored and chopped
  • 2 cloves garlic, peeled and minced
  • 12 ounces uncooked spaghetti
  • 24 ounces Spaghetti sauce
  • 1 can (14.5 ounces) diced tomatoes
  • 3 cups water or beef broth
  • Parmesan cheese, to garnish

Instructions

  • Using the SAUTE feature on NORMAL, heat the olive oil. 
  • Add the Italian sausage, breaking apart with the back of the spoon. Cook, stirring regularly until it loses its pink and begins to render fat.
  • Add onions, sweet peppers, and garlic and cook until softened.
  • Drain the meat of any excess grease.
  • Add Italian seasoning and salt and pepper to taste.
  • Cut the uncooked spaghetti in half and place them in the pot on top of the meat in a crisscross pattern.
  • Add Spaghetti sauce, diced tomatoes, and water. Do NOT stir. Push the noodles down gently so they’ll be submerged in the liquid.
  • Close the lid of the Instant Pot, making sure the valve is on SEALING position. Cook on HIGH pressure for 7 minutes. When the 7 minutes and the pressure cooker beeps, do a QUICK release.
  • Press CANCEL to turn off the Instant Pot and open lid. Let noodles stand for about 1 to 2 minutes and stir to distribute sauce.
  • Ladle on serving plates and sprinkle with Parmesan cheese, if desired. Serve hot.
