Ingredients

  • 4 Cups Vegetable Broth divided
  • ½ Large Yellow Onion roughly chopped
  • 1 Large Celery Stick roughly chopped
  • 1 Tablespoon Lightly Dried Parsley plus extra for garnish
  • ½ Teaspoon Ground Thyme
  • ½ Teaspoon Salt
  • ¼ Teaspoon Pepper
  • 1 Medium Cauliflower broken into florets
  • 1 Medium Potato diced
  • Zest and Juice of ½ Lemon
  • 2 Tablespoons Dijon Mustard

Instructions

  • Heat ¼ cup of vegetable broth in a pot. Add the onion, celery, parsley, thyme, salt, and pepper. Cook for 8-10 minutes, until the onion is soft. Add more vegetable broth as necessary to prevent sticking.
  • Add the cauliflower, potato, and the remaining vegetable broth. Bring to a boil, then reduce to a simmer, cover, and cook for 8 minutes.
  • Using a slotted spoon, remove half of the cauliflower from the pot and set aside. Let everything simmer for another 5 minutes.
  • Pour the mixture into a food processor and blend until smooth.
  • Return to the pot and add the reserved cauliflower. Stir in the lemon zest, lemon juice, and mustard. Sprinkle with additional parsley. Add additional salt, to taste. Enjoy!
