You can substitute ground beef with ground turkey or Italian sausage.
Opt for sturdy pasta shapes like macaroni, rigatoni, or penne for this soup. Bowtie pasta works best, but lasagna noodles may overcook in a pressure cooker.
Swap diced tomatoes with crushed tomatoes for a heartier broth.
As the soup cools, it will thicken due to the noodles absorbing the liquid. Simply add extra broth or water to thin it out as needed.
You can replace the canned tomato products with 24 ounces of marinara sauce and 1 cup of water for either cooking method. If using a pressure cooker, you might need an additional cup of water after cooking to adjust the consistency.
