Roasted Cauliflower Soup Recipe

If you've been following me for a while, you know I live in the sunny Central Valley of California. Soups and Stews are a favorite in our home in all year long!

Often times recipes and inspiration come from my farmers market. Here in the valley we have amazing produce and a year-round market.

Right now we are enjoying super sweet citrus, beautiful kale, chard and cauliflower. Since cauliflower is in season and at the peak of flavor, this Roasted Cauliflower Soup Recipe is definitely a meal to enjoy!

Grocery list for Cream of Cauliflower Soup Recipe

  • cauliflower
  • parsnips
  • yellow onion
  • Yukon gold potatoes
  • vegetable or chicken stock
  • spices - turmeric

Roasting the vegetables adds a layer of flavor to the soup!

How to make Cream of Cauliflower Soup

  1. Start by cranking up the oven. Preheat it to 450.
  2. While it is preheating, clean the cauliflower. Remove the green leaves and break it into uniformly sized pieces.
  3. Peel the parsnips and slice them into large chunks. You want both vegetables to be about the same size so they finish cooking in the same period of time.
  4. Put the vegetables on a cookie sheet, roast for 10 minutes, then remove, flip the vegetables and return to the oven for another 10 minutes.
  5. When they are done, the vegetables will be tender and golden brown.
  6. While the vegetables are roasting, dice the onions and potatoes. Add the onions and potatoes to a large stock pot with olive oil and sauté.
  7. Add the spices and the minced garlic & saute for another minute, then add about half of the stock. Increase the heat to high, cover tightly and cook until the potatoes are tender.
  8. Using a blender puree the potatoes until they are creamy and smooth. Do the same with the vegetables when they come out of the oven. Add the remaining chicken stock to the blender when you whirl up the vegetables.
  9. Add both pureed potatoes and vegetables to a stock pot, stir well to combine. Adjust to taste with salt & pepper.

Garnishes for Roasted Cauliflower Soup Recipe

  • creme fresh
  • sour cream
  • chunks of roasted cauliflower
  • bacon bits
  • popcorn

If you save out some of the roasted cauliflower you can use it to garnish your soup. Popcorn is also tasty garnish! Toss a handful of popcorn on top of the soup and it gives it a really nice texture. (Your kids will think that's cool and forget that this meal is good for them!)

Cost: $20

Ingredients

  • 1 head cauliflower
  • 2 parsnips peeled
  • 1 sweet yellow onion peeled and chopped
  • 3 yukon gold potatoes about 1 pound
  • 1 clove garlic minced
  • 4 cups chicken or vegetable stock low sodium
  • 1 teaspoon salt (divided)
  • ½ teaspoon black pepper (divided)
  • ½ teaspoon turmeric
  • pinch red pepper flakes

Instructions

  • Preheat the oven to 450 degrees.
  • While it is preheating, clean the cauliflower. Remove the green leaves and break into pieces. Peel the parsnips and slice into large chunks. You want both vegetables to be about the same size so they finish cooking at the same time.
  • Put the vegetables on a cookie sheet, sprinkle with olive oil, salt and pepper. Into the oven they go. Roast for 10 minutes, then remove, flip the vegetables over and return them to the oven for another 10 minutes.
  • While the vegetables are roasting, dice the onions and potatoes. Cut the potatoes into small cubes (about 1 inch) so they will cook quickly. Add the onions and potatoes to a large stock pot with olive oil and sauté for about five minutes.
  • Season with the remaining salt & pepper, red pepper flakes and turmeric. Add the minced garlic also & saute for another minute, then add about half of the stock. Increase the heat to high, cover tightly and cook until the potatoes are tender.
  • Using a blender puree the potatoes until they are creamy and smooth. Do the same with the vegetables when they come out of the oven. Add the remaining chicken stock to the blender when you whirl up the vegetables.
  • Serve topped with a swirl of creme fresh and roasted cauliflower.

Notes

With this soup, I recommend using Yukon gold potatoes, when cooked they have a nice creamy texture.
Optional Garnishes - Creme Fresh or sour cream, chunks of roasted cauliflower, bacon bits or popcorn.

      I love cauliflower. I like that you roasted it - adding extra flavor - rather than steaming it before adding it to this soup. I will be trying this soon!
