Seasonings & Broth
- 1/2 teaspoon red pepper flakes
- 1/4 teaspoon black pepper
- 1/2 teaspoon salt (more to taste)
- 16 oz chicken broth
- 1 quart water
- 1 teaspoon chicken bouillon (optional, for deeper flavor)
This combination keeps the soup budget-friendly while delivering bold, cozy flavor.
Low-Carb Veggies & Creaminess
- 1 head cauliflower, cut into small florets

Cauliflower steps in as a low-carb alternative to potatoes, while greens add a nourishing, weeknight-friendly balance.
How to Make It
Brown the Sausage
In a large soup pot over medium-high heat, crumble and brown the Italian sausage until fully cooked and fragrant.
This step builds that savory, protein-packed base that makes the soup feel like true comfort food.
Soften the Aromatics
Add the chopped onion and garlic to the pot.
Cook until the onion turns translucent, then season with salt, pepper, and red pepper flakes for gentle warmth.
Build the Broth
Reduce heat to medium and stir in the cauliflower florets, chicken broth, and water.
Add bouillon if using, creating a rich, slow-simmered flavor perfect for a cozy weeknight meal.
Simmer Until Tender
Let the soup cook for 15–20 minutes, until the cauliflower is fork-tender and the broth feels well blended.
This is where the soup transforms into a comforting, nutritious slow-simmer dinner.
Finish with Greens and Cream
Lower the heat and sprinkle in the chopped kale or Swiss chard.
Pour in the heavy cream, stir gently, and let everything warm through. Serve hot and comforting.
