Finally, add the bowtie pasta. Stir it in and let the soup simmer for the time indicated on the pasta package, usually 9-11 minutes. Stir occasionally to prevent sticking. You want the pasta to be al dente—it will soften a bit more as it sits in the hot soup. I once overcooked the pasta, and it turned mushy in the bowl, which was a textural disappointment. As soon as the pasta is done, turn off the heat. The soup will be thick, rich, and perfectly hearty. Now, it’s time for the signature lasagna touch.
Pro Tips for Best Results
My number one tip is about the pasta. I’ve tested this three different ways: cooking the pasta directly in the soup (best for immediate serving), cooking it separately and adding it per bowl (best for leftovers), and using a different shape. Cooking it in the soup gives the broth a lovely, slightly starchy thickness and lets the pasta absorb all the flavor. However, if you plan on having leftovers, cook the pasta separately and store it apart from the soup to prevent it from bloating and absorbing all the broth overnight.
The second tip is all about layering the flavors. That minute of blooming the dried spices in the sausage fat is non-negotiable. It transforms them from dusty to dynamic. Also, using both tomato sauce and diced tomatoes with herbs gives you the perfect texture—creamy from the sauce and chunky from the tomatoes. Don’t substitute plain diced tomatoes; the Italian herbs in the can are a built-in flavor boost that makes a big difference.
Finally, don’t skip the finishing toppings. They are what truly make it “lasagna” soup. The cool, creamy dollop of ricotta cheese melting into the hot soup is essential. It mimics the rich ricotta layer in traditional lasagna. A generous sprinkle of Parmesan cheese adds the salty, umami punch, and the fresh parsley gives a necessary pop of color and freshness that cuts through the richness. I serve the toppings in bowls on the table so everyone can build their perfect bowl.
Common Mistakes to Avoid
The first mistake I made was using ground beef instead of Italian sausage. I thought I could shortcut with what I had. The soup was fine, but it was missing that distinctive, fennel-spiced, savory depth that makes it taste like lasagna. Italian sausage is the soul of this dish. If you want a lighter version, use mild Italian turkey sausage, but don’t skip it. The seasoning packed into the sausage is irreplaceable. (See the next page below to continue…)
