Regardless of the type of lasagna noodles you choose, the key is to ensure they are added to the soup at the right time to cook to perfection. You can cook them separately and add them just before serving to prevent them from becoming overly soft or mushy during the simmering process. You can use broken up regular lasagna noodles as shown or no-boil, whole wheat, vegetable-based, gluten-free, or a different pasta like fettuccini, spaghetti.
