It doesn't get any better than a big bowl of Sausage Fennel Soup during the fall and winter months. This soup is bursting with Italian flavors and sure to warm you up!
I love soups that are hearty and filling, but at the same time are healthy and won't weigh you down. This one is made with without cream or dairy and lightened up a bit with the addition of lots of veggies.
It's flavored with one of my favorite underutilized vegetables - Fennel. The fennel gives it a mild anise flavor and pairs so well with the Italian spices in the sausage.
This soup is also made with mushrooms, carrots, and kale that are all simmered in a savory broth in a Dutch oven on the stove top. It's earthy, sweet, and slightly spicy all at the same time.
It's perfect for a weeknight meal and can be enjoyed for lunch or dinner. The leftovers last for a few days in the refrigerator and it can be frozen and enjoyed at a later time.

What Is Fennel?
Fennel is an aromatic Mediterranean vegetable that consists of a large white bulb at the base, green stalks, and small feathery fronds. It is a member of the Apiaceae family, along with carrots, celery, and parsley.
Fennel has a flavor that is similar to anise, or licorice. The entire plant is edible - The bulb can be eaten raw or cooked and used in everything from salads to risotto to stuffing.
The stalks may be chopped and used to make a homemade vegetable stock and the fronds can be minced and used as a garnish.
I find that fennel can be used much in the same way that you would use celery. It can be enjoyed raw, braised, sautéed on the stove top, roasted in the oven, or used to flavor soups and stews.
When added to soups, the strong anise flavor of the fennel tends to soften and it sweetens a bit as it cooks. Fennel seeds are often added to sausage, giving it a distinctly 'Italian' flavor.
You can find fennel in the produce section of most grocery stores, or at your local farmer's market, depending on where you live.
How To Cut Fennel
It may seem intimidating, but the process of cutting fennel is simple. All you need is a cutting board and a sharp knife.
- Start by placing a fennel bulb on a cutting board. Cut both the top and bottom portion from the fennel bulb with a knife, making sure to save some of the fennel fronds for garnish.
- Discard the woody bottom portion of the fennel and feel free to save the stalks for another recipe, or discard them as well.
- Peel any damaged, brown, or tough outer layers and discard.
- Cut the fennel bulb in half.
- Place the flat surface of one of the fennel halves on the cutting board and dice it just as you would an onion.
- Repeat with the other half of the fennel bulb, making sure to place the flat surface on the cutting board when chopping it with a knife.
One medium to large fennel bulb should yield roughly 1 cup of diced fennel.
How To Add Flavor To Soup
One of the best ways to add flavor to any soup is to use a variety of aromatic vegetables and opt for high quality, minimally processed ingredients.
This soup is made with minced garlic, onions, and fennel, all of which are sautéed in olive oil and provide the dish with a great base of flavor.
I love to use a variety of vegetables when making soups, because each one of them adds a distinct flavor and texture to the overall dish.
This one is made with mushrooms, which provide that quintessential umami flavor, along with carrots for sweetness and kale for earthiness.
It's important that each of the ingredients is added in the correct order and sautéed along with olive oil, salt and pepper to achieve optimal flavor and texture. It takes a bit longer than simply dumping everything into a soup pot at once, but the results are worth the effort.

You can opt for mild or spicy Italian sausage, depending on your preferred level of spiciness.

Once most of the vegetables are sautéed and the chicken broth is added to the Dutch oven, the soup is brought to a boil and then reduced to a low boil for 15 minutes.
After 15 minutes, the sausage and kale is added to the soup and it cooks for another 5 minutes on a low boil.

Can I Sub Any Of The Ingredients?
Yes, this soup can be customized to your tastes!
- Feel free to use any variety of mushrooms you like in place of white button mushrooms. Baby Bella (cremini), Portobello, shiitake, oyster, chanterelle, or porcini are all great choices. If using another variety of mushroom, simply prepare just as you would white button mushrooms.
- Any variety of ground Italian sausage may be used in place of pork. The spice level can be adjusted according to the type of sausage used. Alternately, red chili flakes may be added for extra spice.
- The kale may be swapped out for any hearty greens of choice, such as Swiss chard, collards, arugula, or spinach.
- Low sodium vegetable broth may be used in place of chicken broth.
- Feel free to add 1-2 cans of drained cannellini beans to make this soup even heartier.
What To Serve With Fennel Sausage Soup
Once all of the vegetables are tender and the soup is fragrant, it's time to serve.
I love to garnish this soup with some of the reserved fennel fronds. The fronds provide some extra color and fresh anise flavor. Feel free to mince the fennel fronds, or simply tear them with your fingers.
- When it comes to savory soups like this one, I love to serve them with some cheddar chives scones or homemade biscuits for dipping.
- You can also serve it with some warm, crusty bread or Italian breads like focaccia or ciabatta.
- Italian soups are great garnished with some grated Parmesan, Asiago, or Pecorino Romano cheese if dairy isn't an issue for you.
- A dollop of pesto may be added to the soup for extra flavor and richness.
- Soup is perfect paired with this Italian mozzarella grilled cheese or pesto grilled cheese sandwich as well as a pesto flatbread pizza or arugula pesto prosciutto pizza.
