Lightened Up One-Pot Lasagna Soup Recipe

Lasagna is comfort food, even if you didn’t grow up in an Italian family. The baked pasta dish has layer upon layer of cheese, meat and more cheese that will put you into a food coma – albeit a delicious one. Instead of overindulging in this Italian classic this winter, try finding comfort in a bowl of lasagna soup – a lighter, but no less delicious – alternative to this classic dish.

About this lasagna soup recipe

As the name implies, lasagna soup recipe captures all the flavors that you’ll find in traditional lasagna, but in liquid form: tomato sauce, cheese, sausage and pasta.

Lasagna Soup ingredients

The soup starts off with a mixture of onions, garlic, spices and tomatoes – all of which are typically found in the tomato sauce that is the backbone of a good lasagna. Two types of tomatoes are used: canned, diced tomatoes and tomato paste. The tomato paste adds a very intense tomato flavor, making the soup seem much richer than a soup made with diced tomatoes alone would. 

Measuing Out Tomato Paste

Since this is a soup, rather than a baked dish, it doesn’t need anywhere near as much cheese as a traditional lasagna. I made a mixture of ricotta, fontina and asiago cheeses while the base of the soup was cooking. This base is added to the bottom of each serving bowl. When the hot soup is added, the cheese melts and adds a wonderful creaminess to every bite, bringing together all the flavors that you get in a bite of regular lasagna.

Cutting back the cheese alone is enough to make this soup “lighter” than traditional lasagna, but I also opted to use a pre-cooked chicken sausage as the primary protein.

Spicy Italian Chicken Sausage

There are quite a few Italian chicken sausages out there to choose from and all are easy to work with when it comes to making soup, since they don’t need to be precooked and bring a lot of flavor to the dish. I used a spicy Italian sausage, but a mild Italian will work equally well. 

You can use any type of pasta in this soup, but a fairly wide, flat pasta is going to give you the best results. Real lasagna noodles are often plain to look at and difficult to break into small, even pieces, so they are not the ideal option for this soup unless they are all you have on hand.

Lasagna Noodles and Malfaldine Pasta

I used malfaldine pasta for my soup. The ribbon-like malfaldine pasta has ruffled edges on both sides and makes for a particularly nice presentation. Mine came in very long ribbons and I broke the long pieces down into 6-inch lengths before adding it to the pot. 

The soup can be made in under an hour and does not need a lot of hands-on cooking time, so it is a good option if your looking for weeknight dinner ideas.
