01 -
Wash, peel and chop all vegetables as indicated in the ingredients list.

In a heavy-bottomed soup pot or Dutch oven, cook the mild Italian sausages according to package directions until browned. Remove to a plate and set aside to cool.
03 -
Melt butter (or heat olive oil) in the same pot and sauté celery and onion until tender and translucent, about 5 minutes. This will also deglaze the pan, incorporating the sausage flavors.
04 -
Add cauliflower and mushrooms to the pot, then pour in chicken broth. Season with salt, pepper, celery seed, sage, thyme, and dried parsley.
05 -
Bring mixture to a boil, then cover, reduce heat to low and simmer for approximately 15 minutes or until the cauliflower is tender. Meanwhile, slice the cooled sausages into rounds.
06 -
In a separate bowl, whisk flour into milk until completely smooth with no lumps. Gradually add this mixture to the pot, stirring constantly. Cook over medium heat for 5-7 minutes until the soup thickens.
07 -
Add the sliced sausage back to the pot and heat through for 2-3 minutes.
08 -
Remove pot from heat and stir in shredded cheddar cheese until completely melted and incorporated. Taste and adjust seasoning with additional salt and pepper if needed.
