  • 1 pound ground sausage Italian Sausage works best (I used mild)
  • 3 slices bacon, sliced into smaller bits
  • 1 cup onion chopped
  • 3 garlic cloves, chopped
  • 1 head fresh cauliflower, chopped
  • 5 cups low-sodium chicken broth
  • 1 tsp dried oregano
  • salt and pepper to taste I like to season it at the end so that I can taste repeatedly and adjust as necessary.
  • 1 cup heavy whipping cream
  • 3 cups fresh kale, stems removed
  • parmesan for topping optional


  • Add the pieces of bacon and sausage to a large pot (Dutch oven works best) on medium-high heat.
  • Cook until the sausage and bacon have browned. Drain any excess fat, but reserve about a couple of tablespoons of fat in the pot for flavor. (I didn't have to drain any fat.)
  • Add in the chopped onion and cook for 2-3 minutes until the onions are translucent.
  • Add the garlic, chicken broth, fresh cauliflower, oregano. Stir to combine.
  • Cover the pot and reduce the heat to medium. Cook for 15 minutes or until the cauliflower is soft and can be pierced with a fork.
  • Uncover the pot and add the heavy cream, chopped kale, salt and pepper to taste.
  • Cook for a couple of minutes until the kale wilts.
  • Cool before serving.



  • For me a Dutch oven yields the best results. You can use whatever soup pot you want in the recipe.
  • You can use 1/2 cup heavy cream to reduce calories in this recipe.
  • You can add 1/2 tablespoon of Italian Seasoning to standard ground sausage if you choose not to use Italian sausage.
  • I like a lot of kale in my soup (it's loaded with fiber) you can adjust to your taste.
  • Sometimes, when I freeze soup with dairy, the dairy will separate from the soup (especially the longer you freeze). If you know you are planning to freeze in advance, I recommend adding the cream and kale to the soup after you have frozen it, as opposed to adding it when you cook the original batch.
