Slow Cooker Italian Sausage Soup

My grandma was the type of grandma that religiously believed that a big bowl of chicken soup was the cure-all for just about any illness. Without fail, she would show up with homemade chicken soup within hours of learning about anyone being sick, whether it was a relative or a neighbor, or even the mailman.


This Slow Cooker Italian chicken sausage soup is a twist on the traditional chicken soup. It adds super healthy veggies, like zucchini and spinach, and uses Italian chicken sausage instead of regular chicken to jack up the flavor profile. The best part: prep takes only minutes and your slow cooker will do the rest!

So today when I’m not feeling so hot, my first thought is always chicken soup. But I call this slow cooker Italian sausage soup my “postmodern chicken soup” because it is chicken soup, kicked up about ten levels.

A big part of my grandma’s chicken soup was noodles. Of course, I eat Paleo, so drop the noodles. But, I’m not just left with a bowl of chicken and broth. The first way this recipe bumps up chicken soup is by adding tons of vegetables. There are the normal chicken soup ones – carrots, celery, and onions – but there are some new additions (which might remind some people of Italian wedding soup): tomatoes, zucchini, and spinach.

The tomatoes add a bright, almost citrus flavor to every bite. The zucchinis, while adding vitamins and nutrients, also make a good substitution for noodles, I think. My grandma always used bowtie noodles, so zucchini pieces are about the same size and have a similar tender chewiness, so you really won’t miss the noodles at all anyway.

And finally, spinach – one of the kings of the vegetable world. Spinach has tons of iron. And you know what Popeye says about spinach – it will make you strong! (There’s actually some truth to that, with all the iron it has!)

Also, instead of using regular chicken, this recipe uses Italian chicken sausage. It has all the great protein of regular chicken, but the flavor is kicked up with traditional Italian sausage flavorings: fennel, garlic, oregano….YUM. You could use pork Italian sausage, but then of course it wouldn’t be chicken soup! And I’m a fan of the chicken because it has all the protein, with less fat. Perfect for Paleo eaters.

In this recipe, you simply get the sausage out of its casing – no need to make meatballs because when you brown the sausage, it crumbles into little balls anyway. If you’re having trouble getting the sausage out of the casing, it is actually easy to do if you just snip the end of the sausage with kitchen shears (make sure to wash them before putting them back in the drawer!) or a sharp knife, and then squeeze the sausage right out of the casing.

Make sure you brown your sausage and cook your veggies according to the recipe before you put everything into the slow cooker. It won’t totally ruin it if you don’t, but, trust me, you’ll have a much more developed flavor if you take this step. It will have that extra something and the flavors will all blend together better if you follow the browning instructions.

  1. I just want to let you know that I invested my time in making this soup. Totally awesome and hearty. My husband loved it as well and it has been placed in our file to use monthly in our meal planning. Thank you for sharing. I also purchased your cookbook with meal plans. I don’t believe I saw one recipe that made me go — oh I so wouldn’t eat that! I am excited that I have found you and you are in my world! Thanks again.

  2. Oh my goodness, this soup is fabulous! I didn’t have oregano so I used dried Italian seasoning and it worked beautifully. Even my Texas-born hubby loves it! Thanks for sharing.

  3. This sounds wonderful! I love to spiralize vegetables to take the place of noodles. You could spiralize the carrots or zucchini……or both. I love to add turnip or rutabaga noodles, yes really. They get really sweet cooking in the soup. The more vegetables the better.

  4. So if I want to cook it in the Dutch oven do I still need to cook it for 2 hours? How long does it need to cooki if I am doing it all stovetop?

  5. I’ve never been a soup person however this recipe sounded so good I had to try it. I used hot italian sausage, added zucchini and yellow squash and all the other veggies you recommended. The result was so amazing that i craze this soup at least twice a month! Thanks so much for turning me into a soup person!
