Slow-Cooker Lasagna Soup

Every fall and winter, our staff has a soup rotation. I have modified this recipe so I can prep it the night before and put it in the slow cooker in the morning. My colleagues love it! —Sharon Gerst, North Liberty, Iowa

    Very good. I will make again. My husband isn't a fan of soups. I asked him while he was eating the soup how it was and he didn't have any complaints. I used one quart of my home canned tomatoes (what I had on Hand) and two cans of mushrooms because I did not have any fresh ones. Already made two containers for lunches next week.

    I love any recipe that goes into the slow cooker! This is a flavorful soup. We really enjoyed it. I topped ours with a spoonful of ricotta cheese!

    This is my #1 recipe to make for company. It's easy, artisanal-level taste, and it frees your evening so you can actually visit. I haven't had a single person over yet who doesn't love this soup. Plus it freezes well and is great for lunches.

    Used spaghetti sauce instead of tomato sauce. Used beef broth instead of chicken.

    My husband and I loved this recipe. I used half sage sausage and half a spicy sausage. I will definitely be making this again.
