Easy Cauliflower Soup with Dijon and Parmesan


You know those nights were just nothing other than a hot homemade soup will do? But you also don’t want to wait three hours for it? Here’s your answer. I had such a night recently.


Returning from an evening distance run, I was too chilled to settle for anything less than soup, but too lazy tired to bother with something fancy. Even roasting the cauliflower was out. So this was my solution! We devoured this soup, with or without the croutons.



Serves 3-4 as an entree

Prep: 15 min      Cook: 20 min

  • 1 small to medium white onion, chopped
  • 1 tbs olive oil
  • 1 medium head cauliflower, chopped
  • 2 plump cloves of garlic, minced or put through a press
  • 3 1/2 cups vegetable stock
  • 1/2 cup shaved parmesan (it’s worth it to get the quality, aged, raw milk parmesan)
  • 2 heaping tablespoons coarse ground dijon mustard
  • Optional garnishes (to serve): chives, more shaved parmesan, olive oil, cracked pepper

Crouton Ingredients (optional)

  • 2 pieces of bread (I used sourdough)
  • 2 tbs olive oil or melted butter
  • 2 tbs dijon mustard (coarse or fine ground will do)
  • salt to taste


In a large saucepan, saute the onions in the oil over medium-high heat until soft and transparent. Add the cauliflower, cover, and cook for about 5 minutes. Add the vegetable broth and garlic and bring to a boil. Cover, reduce heat to medium-low and simmer for about 15 minutes or until cauliflower is soft. Turn off heat and stir in the parmesan and mustard. Transfer soup to a blender and puree until smooth. Serve with optional garnishes or croutons (see below)

Crouton directions:

Preheat the oven to 350 F. Chop or tear the bread into bite size pieces. Spread over a baking sheet and toss the bread pieces with the oil, mustard, and salt. (I mixed with  my hands to make sure the mustard got spread throughout). Bake until crisp and browned around the edges, about 10 minutes. Keep a close eye on them! They burn pretty easily.

  1. I know EXACTLY what you mean. Nothing like a quick, creamy vegetable soup for those cold nights after a long workday. This one looks so delicious–I love the idea of combining mustard and cauliflower.

    Although, now that you mentioned roasting, I wonder how this soup would be if you roasted the cauliflower first…

    • Right? Pureed veggie soups are just the best. Roasting cauliflower in this recipe would be just fantastic! My goal here was a recipe that was flavorful enough without the extra time spent roasting, but by all means, feel free to roast it. 🙂 Would love to hear your thoughts if you try it!

  2. This is great! I would have roasted the cauliflower, but, it’s great to know that it tastes good without that step. Definitely will try this, because I like quick, one-pot meals when I’m really busy.

      • I”ll let you know probably tonight. I just woke up after working a nightshift and I’m off to see my son and taking him groceries (he moved out to go to university), my husband is working until very late, so, it will be my daughter and I. I know she would love this also.

        • Ok, I made it for my daughter and I tonight and it was great! Loved it so much… quick, healthy, delicious! I added both grainy dijon and smooth dijon to it.I didn’t make the croutons, but, we had some really rustic bread that we dipped into it, yum. 🙂
