Why you’ll love this cauliflower potato soup

I love this Cauliflower and Potato Soup as it’s both hearty and delicious, but lightly creamy (just 1/4 cup of cream).

The star of this soup is definitely the toppings. A bit of the cauliflower is roasted off, together with some Brussels sprout leaves and put on top of the soup, for great texture and flavour. And to finish it off is a sprinkling of crumbled, tangy goat cheese.

You could enjoy this soup as a lunch or dinner soup or as an elegant starter soup for any meal.

Ingredients and Substitutions



Heavy Whipping Cream – This soup only calls for 1/4 cup of heavy cream, but if you don’t have heavy cream or you’d prefer something lighter, simply combine a lighter cream with a half teaspoon of cornstarch and add it to the soup instead. For a dairy-free option, just skip it altogether.

Brussels Sprouts – To prepare the Brussels sprouts, simply cut off the core end by about 1/2-inch, then start peeling the outside leaves off one by one. Stop when you get to the middle and the leaves don’t separate easily and discard that inner bit.

Goat Cheese

Cook’s Notes

I say this every time I post a soup recipe, but I think it can never be said enough. Be sure to season your soup well with salt and freshly ground pepper. If you taste the soup and it seems at all bland, you need more salt!

If your soup ends up too thick (maybe you started with an extra big cauliflower or potato :), simply thin with a little more chicken broth.

Making ahead, storing and freezing.

You can make the soup up to 3 days ahead and simply re-warm to serve. The roasted cauliflower and Brussels sprout leaves can be done ahead as well, or just before serving.

Due to the cream in this soup, freezing is not recommended, as the texture of the soup will change.

Change It Up!

Add crispy herb croutons and/or crumbled, cooked bacon to the topping. Alternately, add a bit of very finely diced, uncooked bacon to the onion at the start to give your soup a bit of a smokey, bacon flavour.

Prep Time: 15 minutes
Cook Time: 35 minutes
Total Time: 50 minutes
Yield: 5 servings


  • 2 lb. (0.91 kg) cauliflower, quartered and cored
  • 2 Tablespoons (2 Tbsp) extra-virgin olive oil
  • 1/2 small (0.5 small) onion, diced
  • Salt and Freshly ground pepper, to taste
  • 1 large (1 large) baking potato (such as Russet), peeled and cut into 1-inch pieces
  • 4 cups (940 ml) chicken broth
  • 3 (3) thyme sprigs
  • 1/4 cup (59.5 ml) heavy whipping cream, 35% b.f.
  • 8 (8) Brussels sprouts, core end trimmed and separated into leaves
  • 4 oz. (113.4 g) goat cheese, crumbled


  • Preheat the oven to 375 F. Take one quarter of the cored cauliflower and cut it in to 1/2-inch thick flat slices. Set aside.
  • Coarsely chop the remaining cauliflower.
  • In a Dutch oven or soup pot, heat the olive oil over medium heat. Add the onion and a pinch of salt and cook, stirring occasionally, until softened, about 3-4 minutes. Stir in the diced potato and the chopped cauliflower, then add the chicken stock and the thyme sprigs. Bring to a boil, then reduce the heat to medium low and simmer, stirring occasionally, until the vegetables are very tender, about 30 minutes. Discard the thyme sprigs.
  • While soup is simmering, place reserved cauliflower floret slices in an even layer on one end of a baking sheet. Prepare the Brussels sprouts as directed above and scatter over the other end of the baking sheet. Drizzle with a bit olive oil and season with salt. Roast for 5 minutes in the preheated oven. Remove from oven and transfer Brussels sprout leaves to a plate. Return to oven and roast a further 10-15 minutes, or until the cauliflower florets are golden on the bottom. Remove from oven and transfer florets to a plate, with the golden side up.
  • Using an immersion blender or in two batches in a blender, puree the soup until very smooth. Return the soup to the pot and stir in the cream. Warm over moderate heat. Taste soup and season generously with salt and some freshly ground pepper, to taste.
  • To serve, ladle into bowls and top with some roasted cauliflower florets and roasted brussels sprout leaves. Sprinkle with crumbled goat cheese and a grind of freshly ground pepper.
  • Making Ahead: The soup can be made ahead and refrigerated for up to 3 days. Reheat gently before serving, then top with garnishes.
