Tips for the Best Italian Sausage & Kale Soup

For the most flavor, let the sausage brown until it forms little caramelized bits in the pot—those browned bits enrich the soup’s base.

Use full-fat heavy cream for the best texture and mouthfeel. Add the kale just before finishing to keep it tender but vibrant.

If using cauliflower, don’t overcook—it should be fork-tender but not mushy. Finally, always taste before serving and adjust salt and spice levels to your liking.

  .
• Reheating: Warm gently on the stovetop over low heat. Avoid boiling once cream has been added.
