Ingredients

Scale

Meat and Fat

  • 1 Tbsp. olive oil
  • 12 oz. mild Italian sausage, removed from casing
  • 3 slices bacon, chopped

Vegetables

  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • 6 cups cauliflower florets (about 1 1/4 pounds)
  • 4 cups chopped curly kale

Liquids and Dairy

  • 1 (32 oz.) carton chicken broth
  • 1 cup half and half

Seasonings

  • Kosher salt, to taste
  • Fresh black pepper, to taste
  • Red pepper flakes, for serving (optional)

Instructions

  1. Cook Meat: In a large dutch oven or heavy-duty soup pot, heat olive oil over medium heat. Add the Italian sausage and chopped bacon. Cook, breaking up the sausage, until the sausage is browned and the bacon is crisp, about 8-10 minutes. Remove the cooked meat with a slotted spoon to a plate, reserving 2 tablespoons of the grease in the pot.
  2. Sauté Aromatics: Add the diced onion to the pot and cook until soft and translucent, about 3-4 minutes. Stir in the minced garlic and cook for an additional 30 seconds, stirring constantly to avoid burning.
  3. Simmer Cauliflower: Add the cauliflower florets and chicken broth to the pot. Season with kosher salt and freshly ground black pepper to taste. Bring to a simmer uncovered, cooking until the cauliflower is tender, about 15 minutes.
  4. Puree Soup: Using a high-powered blender or an immersion blender, puree the soup until smooth and creamy.
  5. Add Dairy and Greens: Return the pureed soup to the pot, stir in the half and half, and bring back to a gentle simmer. Add the cooked sausage, bacon, and chopped curly kale. Simmer the soup until the kale is wilted, approximately 5 minutes. Adjust seasoning with salt as needed.
  6. Serve: Ladle the soup into bowls and serve with a sprinkle of red pepper flakes for an optional spicy kick.

Notes

  • For a vegetarian version, omit sausage and bacon and use vegetable broth instead of chicken broth.
  • Use an immersion blender for easier cleanup and direct blending in the pot.
  • Your choice of kale can be substituted with spinach or swiss chard if preferred.
  • Red pepper flakes add a nice touch of heat, but can be omitted for a milder flavor.
  • Leftovers store well in the refrigerator for up to 3 days and freeze nicely for up to 2 months.
