Brown your hot Italian sausage in a stock pot over medium-high heat. Strain most of the fat.
Reduce heat to medium and add diced onion and minced garlic. Stir for 2 minutes, until translucent
Add fennel seeds and red pepper flakes. Toss until fragrant.
Add chicken broth, scrapping any browned bits off the bottom of your pan. Add cubed potatoes, cover - and allow to simmer for about 20 minutes, or until potatoes are fork tender.
Add cream, shredded kale, parmesan cheese, salt, and pepper (to taste).
Allow to simmer for about 5 minutes - until kale is soft and vibrant.
Serve with an additional sprinkle of red pepper flakes.
Enjoy!
