  • 4 slices bacon diced
  • 1/2 medium (about 70g) onion diced
  • 4 cloves garlic minced
  • 1 pound (~454g) bulk Italian sausage
  • 1/2 teaspoon Italian seasoning
  • 1 teaspoon crushed red pepper flakes or to taste
  • 1 teaspoon fennel seed
  • 1.5 cups (~100g) kale roughly chopped, tough stems removed
  • 5 cups chicken broth
  • 1 small head (250-300g) cauliflower cut into small florets
  • 1 cup heavy cream
  • salt and pepper to taste


Fry Bacon

  • In a large pot over medium heat, fry bacon for 8-10 minutes or until crisp. Drain and set aside. Reserve the bacon drippings in the pot.

Brown Sausage and Wilt Kale

  • Add the onion and garlic to reserved bacon drippings, and cook for 1-2 minutes or until fragrant.
  • Add Italian sausage, Italian seasoning, red pepper, and fennel to pot. Cook for 7-9 minutes, or until sausage is browned and crumbled.
  • Add kale, and cook for 1-2 minutes or until just beginning to wilt.

Add Broth and Cauliflower

  • Increase heat to medium high. Add broth to pot and bring to a boil.
  • Add cauliflower and stir to combine. Continue to boil for 8-10 minutes, or until cauliflower is tender.

Add Cream and Bacon

  • Reduce heat to medium. Stir in cream and bacon. Add salt and pepper to taste if desired.


  • Serve and enjoy!


  • I really recommend using bone broth rather than standard chicken broth for this recipe if possible. It ups the flavor and the health profile!
  • It's normal for this soup to settle in the fridge, so make sure to give it a stir before reheating on the stove or in the microwave.
  • The red pepper flakes add just a bit of heat to up the warming factor of this soup. Feel free to up the amount for more kick, or lower it if you're using hot Italian sausage.
