A creamy and low-carb Tuscan-style soup made with Italian sausage, fresh spinach, and cauliflower, simmered in flavorful chicken broth and enriched with heavy cream. This hearty and comforting keto-friendly soup is perfect for a low-carb dinner that doesn’t skimp on taste or texture.

  • Total Time: 30 minutes
  • Yield: 4 servings

Ingredients

Meat and Dairy

  • 1 pound Italian sausage
  • 1 cup heavy cream

Vegetables & Aromatics

  • 1 onion, diced
  • 2 cups cauliflower florets
  • 2 cups spinach or kale
  • 2 cloves garlic, minced

Liquids & Seasonings

  • 3 cups chicken broth
  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste

Instructions

  1. Brown the sausage: In a large pot over medium heat, brown the Italian sausage until fully cooked, breaking it apart with a spoon. Once browned, carefully remove any excess grease from the pot to keep the soup from becoming too oily.
  2. Sauté aromatics: Add the diced onion and minced garlic to the pot with the sausage. Cook, stirring occasionally, until the onions are softened and translucent, about 3-4 minutes, enhancing the soup’s base flavor.
  3. Add vegetables and broth: Stir in the cauliflower florets, chicken broth, Italian seasoning, salt, and pepper. Bring the mixture to a simmer over medium heat.
  4. Simmer until tender: Let the soup simmer gently for 10 to 12 minutes, or until the cauliflower is tender when pierced with a fork, allowing flavors to meld.
  5. Finish with cream and greens: Reduce heat to low and add the heavy cream and fresh spinach or kale. Stir and cook for another 2 to 3 minutes until the greens are wilted and the soup is heated through.
  6. Serve warm: Ladle the soup into bowls and enjoy immediately. Optionally, top with grated Parmesan cheese for extra richness and flavor.

Notes

  • For added richness, sprinkle grated Parmesan cheese on top before serving.
  • You can substitute zucchini for cauliflower for a slightly different texture.
  • This soup keeps well and can be refrigerated for up to 3 days or frozen for longer storage.
  • To make it spicier, consider adding red pepper flakes when cooking the sausage.
