If you love lasagna but hate the effort and time it takes to layer and bake it, this soup recipe is for you. It is loaded with sausage, tomatoes, cheese and pasta and is fun to serve and eat.
Now that the cold weather is really settling in, our minds turn to soup. This great recipe is hearty, filling and sure to warm you up.
Cheesy lasagna has always been one of our favorite meals. But it takes too much time to reasonably put together on a busy weeknight.
This soup makes getting the flavors so much easier. Plus the whole thing is made in the instant pot, so there is only one thing to clean when it is all said and done.
Making lasagna soup
Start by browning a pound of Italian sausage using the saute function of your pressure cooker. It is easiest if you buy bulk Italian sausage, so you don’t have to remove the casings.


Feel free to use hot, mild or sweet sausage, it is up to you and your family’s taste preferences. If there is a lot of grease, go ahead and drain off the excess.
Then add a diced onion and seasonings and saute until the onions are translucent. Add chicken stock and scrape up any bits stuck to the bottom of the pan.

Now break some lasagna noodles into bite sized pieces and toss them in the pot. Cook on high pressure for four minutes and then quick release the pressure.
Now stir in a jar of marinara sauce and cheese. Heat until the cheese is melted and it is ready to go.


That’s it! It really is just as easy at it sounds.
Plus the resulting bowl of soup is so good. My boys don’t love soup in general, but both were big fans of this lasagna soup!
