Roasted Cauliflower Bisque

This cauliflower bisque recipe is light and lovely.  It is inspired by a bisque from Colterra Restaurant in Niwot, Colorado.  Vegans can substitute soy creamer for the whippin’ cream.

  • Method: Stovetop / Oven
  • Cuisine: French


  • one medium head cauliflower (~2lb), chopped into florets
  • 3/4 cup onion, diced
  • 3 Tbsp white wine
  • 3/4 cup heavy whipping cream
  • 1 1/2 Tbsp unsalted butter
  • 4 ounces stale bread, as garnish
  • 3 Tbsp olive oil, divided
  • 3/4 tsp sea salt, divided
  • 1/4 tsp black pepper
  • 1/4 cup parsley, chopped as garnish


  • Preheat oven to 400F.  Line a baking sheet with aluminum foil.  Toss cauliflower florets with enough olive oil to lightly coat (~ 2 Tbsp) and sprinkle with salt (~ 1/4 tsp).  Roast uncovered ~ 10- 12 minutes.  You want them crisp and not browned.  Remove cauliflower and reduce heat to 350F.
  • Add butter to warm stock pot.  Add onions when butter is melted.  Cover and sweat over low heat (you want them translucent and not brown), for ~ 5-7 minutes.  Add cauliflower, wine, and enough water to cover the vegetables with 1″ of water or broth.  Bring to a boil, reduce heat, and simmer covered until cauliflower is soft but not mushy (~ 10 minutes).
  • Immersion blend (or place in blender) the mixture until smooth.  You can also use a blender but will need to add the mixture to the blender in batches.  Add whipping cream.  Add a little more water if you want a thinner consistency.  Stir and add sea salt and black pepper to taste.
  • For Croutons: cut or pull bread apart into 1″ chunks.  Toss in a large bowl with ~1-2 Tbsp extra virgin olive, salt, and pepper and bake on a lined baking sheet at 350F for ~ 7 -9 minutes or until golden and crunchy but not hard.
  • Garnish soup with chopped parsley and croutons.  Happy Eating!  Beckie



  • Want to skip a step to save dishes or time?  Forget roasting the cauliflower and just add it straight to the pot.  It won’t have as sweet or smoky of a flavor, but will still be delicious.
  • A blender will make a smoother bisque, but the immersion blender is easier.
