Ingredients
  

  • 1 lb beef or turkey Italian-style sausage, casings removed
  • 1 tbsp olive oil (as needed if sausage is lean)
  • 1 small yellow onion, diced
  • 3 cloves garlic, minced
  • 4 cups cauliflower florets, bite-size
  • 4 cups low-sodium chicken broth
  • 1/2 cup sun-dried tomatoes, chopped (optional)
  • 1/2 tsp Italian seasoning
  • 1/4 tsp crushed red pepper flakes, optional
  • 3 cups kale or baby spinach, chopped
  • 1 cup heavy cream (or full-fat coconut milk for dairy-free)
  • fine sea salt and black pepper, to taste
  • 1/3 cup grated Parmesan, plus more for serving (optional)

Instructions
 

  • Heat a Dutch oven over medium heat. Add olive oil if sausage is very lean. Add the beef or turkey Italian-style sausage, breaking it into small pieces, and cook 5–7 minutes until browned and cooked through. Transfer to a bowl, leaving drippings in the pot.
  • Add diced onion to the pot with a pinch of salt. Cook 3–4 minutes until softened. Stir in minced garlic and cook 30 seconds until fragrant.
  • Add cauliflower florets and toss with the aromatics 1 minute. Pour in low-sodium chicken broth, scraping up any browned bits. Stir in sun-dried tomatoes (if using), Italian seasoning, and crushed red pepper flakes.
  • Return the browned sausage to the pot. Bring to a gentle boil, then reduce heat and simmer 8–10 minutes, until cauliflower is tender.
  • Stir in chopped kale or spinach and simmer 2–3 minutes until wilted and vibrant.
  • Lower heat to the barest simmer. Stir in heavy cream (or coconut milk) and grated Parmesan if using. Warm gently 2–3 minutes—do not boil—then season to taste with salt and black pepper.
  • Ladle into bowls and garnish with extra Parmesan and freshly ground black pepper, if desired.
