Step-by-Step Instructions
Step 1 – Cook the Bacon
In a large soup pot or Dutch oven, cook the chopped bacon over medium heat until crispy. Remove with a slotted spoon and set aside. Leave about 1–2 tablespoons of bacon fat in the pot for cooking the sausage.
Step 2 – Brown the Sausage
Add ground Italian sausage to the pot. Break it apart with a spatula and cook until browned and fully cooked. Remove and set aside with the bacon.
Step 3 – Sauté Onion and Garlic
In the same pot, sauté diced onion until translucent, about 3–4 minutes. Add minced garlic and cook for an additional 30–60 seconds until fragrant.
Step 4 – Simmer Cauliflower
Pour in the chicken broth and add cauliflower florets. Bring to a simmer and cook until cauliflower is tender, about 15–20 minutes.
Step 5 – Add Cream and Return Meats
Lower the heat and stir in the heavy cream. Return the cooked bacon and sausage to the pot. Simmer gently for 5–7 minutes to meld the flavors.
Step 6 – Add Greens and Seasonings
Add chopped kale or spinach and cook just until wilted, about 3–5 minutes. Season with salt, black pepper, and optional red pepper flakes to taste.
Step 7 – Serve
Ladle the soup into bowls and sprinkle with grated Parmesan cheese. Serve immediately with low-carb bread or enjoy on its own.
Pro Tips for Success
