Roasted Cauliflower and Fennel Sausage Soup

I’m all about easy cooking during these holiday months when things get al little crazier than usual. Luckily it also happens to coincide with soup season. With that, I’m mixing up one of my staple soups by adding in Johnsonville ground Italian Sausage and for extra sustenance.

A must, if I want to feed my hungry boys soup as a bonafide meal.

To build the flavors and the base I roasted cauliflower and fennel. The cauliflower will give the soup a creamy and rich tasting flavor. The fennel gives the soup some contrast, while the sausage gives the ensemble added depth—so make sure you brown the sausage in the pan you’ll be cooking the soup in. Lastly, I threw in some kale for a healthy hit because sneaking greens into soup is a great way to get my family to eat more of it.

For some time-saving tips, make sure to use the Johnsonville’s ground Italian sausage, that way you can bypass decasing the links. The vegetables can be roasted two days in advance.

To finish I melted a slice of Swiss cheese on top and then threw on some crispy kale chips and crunchy onions—totally optional. Skip it if you want, but I promise you aside from giving the soup some visual appeal, it adds another layer of flavor. Aside from that, there is just something about stabbing my way through cheese and slurping it down with my soup that I love.

    I roasted the cauliflower with cooking spray instead of olive oil and used fresh garlic. It came out really well and everyone like it! Will make this again for dinner. Thanks a lot for sharing this recipe :)
