  • 1/2 tablespoon oil
  • 1 pound Italian Sausage
  • 1 large carrot peeled, and diced
  • 1 small onion minced
  • 2 cloves garlic minced
  • 4 cups chicken stock or vegetable broth
  • 16 ounces Italian Stewed Tomatoes
  • 1 cup spaghetti sauce or marinara sauce
  • 1 teaspoon dried oregano
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 1/4 teaspoon red pepper flakes optional
  • 1 cup dried pasta such as rotini, campenelle, elbow noodles, etc
  • 2 cups fresh spinach
  • Mozzarella and Parmesan Cheese for serving


  • Turn Instant Pot to Saute function.
  • Once heated, add in oil. Brown Italian Sausage until almost no longer pink, breaking up sausage as it cooks.
  • Add in onions, carrots, and garlic and saute for 2-3 minutes longer. Turn Instant Pot off.
  • Add stock, tomatoes, spaghetti sauce, and pasta to Instant Pot. 
  • Place lid on Instant Pot and turn knob to sealed. Cook on High Pressure for 4 minutes.
  • Once cook time has elapsed, allow pressure to release naturally for 5 minutes. Then do a quick release for any remaining pressure. Be sure to stand away from vent knob, to protect yourself from steam and liquid that may escape.
  • Stir in spinach to soup and let just wilt.
  • Serve soup with cheese as desired.


Use any Italian sausage you like--chicken, turkey, or pork. 
Using pre-made spaghetti sauce or marinara, gives this soup so much more flavor than plain tomato sauce. 
Whole wheat or regular noodles work well in this soup. Barilla gluten free noodles work as well. Other gluten free brands give off too much starch and do not hold up well in this Instant Pot recipe. 
Leftover Lasagna soup may be stored in air tight container in refrigerator for up to 3 days. You may need to add in a bit of extra stock to reheat, as the noodles will absorb the liquid as they sit.
