Prepare and chop the vegetables.
In a heavy bottomed soup pot or Dutch oven, cook mild Italian sausages according to package directions. Remove the sausages to a plate and set aside to cool.
500 grams mild italian sausage
Melt butter (or olive oil) in the same pot and saute celery and onion until tender and translucent. This will also deglaze your pan.
2 tablespoon butter or olive oil, 1 medium onion, 2 stalks celery
Stir in cauliflower and mushroom and add chicken broth. Add some salt and pepper and the herbs.
4 cups cauliflower, 227 grams white mushroom, 4 cups chicken broth, salt and pepper, ½ teaspoon celery seed , 1 teaspoon dried ground sage , 1 teaspoon dried thyme, 2 teaspoon dried parsley
Bring to a boil. Cover and reduce heat and simmer for approximately 15 minutes or until the cauliflower is tender. Meanwhile, slice your sausages.
In a small bowl, whisk flour into the milk until smooth. Add to the pot. Cook and stir over medium heat for several minutes until the soup thickens.
½ cup flour, 3 cups whole milk
Add in the sausage and heat through.
Remove from the heat and add cheese. Stir until the cheese is melted and everything is thoroughly combined. Take your time now to taste the soup and adjust for seasoning until it tastes perfectly salty.
