Roasted Root Vegetable Soup with Walnut "Croutons" and Crispy Parsley

Root vegetable soup/sunchoke soup with spiced nuts


This soup is my favorite because it combines the earthiness and sweetness of root vegetables with an unexpected spiciness from the cayenne. The herbs add another dimension, and the sweet and spicy walnut "croutons" elevate it from a classic bisque to a multi textured soup worthy of any Pesach table!

Roasted Root Vegetable Soup

  • 2 sweet potatoes, peeled and chopped to 1" pieces
  • 3 parsnips, peeled and diced
  • 2 carrots, peeled and diced
  • 1 small celery root, peeled and diced
  • 1 medium rutabaga, peeled and diced
  • 1 cup non-dairy milk of choice
  • 5 cups water or more, to reach desired consistency
  • 1 ½ teaspoons salt
  • ¼ teaspoon fresh or dried minced rosemary
  • ¼ teaspoon cayenne pepper
  • 1 tablespoon maple syrup
  • 1 teaspoon fresh or dried minced thyme

Walnut "Croutons"

  • ½ cup walnuts
  • 1 tablespoon brown sugar
  • ½ tablespoon oil
  • ¼ teaspoon cinnamon
  • Pinch salt
  • 1/8-1/4 teaspoon cayenne pepper
  • ¼ teaspoon dried rosemary

Crispy Parsley

  • Half a bunch of parsley
  • Cooking spray


  To Prepare Roasted Root Vegetable Soup:

1. Preheat oven to 400°F. 

2. Line two cookie sheets with parchment paper. Generously spray with cooking spray. On one cookie sheet, place the diced carrots and parsnips. On the other cookie sheet, place the sweet potatoes, celery root, and rutabaga.

3. Place both sheets in the oven and roast vegetables until tender, around 45 or so minutes. The sheet with the carrots may be done first, so check once in a while.

4. When all the vegetables have finished roasting, remove from the oven and carefully transfer to a blender or food processor. Add the remaining ingredients. Process until smooth and very velvety.

To Prepare Walnut Croutons: 

1. Preheat oven to 375. Combine walnuts with all the ingredients.

2. Spread on baking sheet and bake 10-15 minutes, or until golden brown and fragrant.

To Prepare Crispy Parsley Garnish: 

1. Clean and shred parsley.

2. Heat a skillet and spray with cooking spray. Let parsley crisp in the pan until reached desired level of crispiness- but keep an eye on it, since it burns easily!

To serve: Spoon soup into bowls, top with walnut croutons and sprinkle with the crispy parsley. Add a sprinkle of cinnamon or cayenne for extra colour. 

Optional: add diced pears.
