Ah…it’s almost Friday, phew! We made it through another week. And as we get closer to the holidays we begin to get busier, which often means less time to think about cooking. So I present you with another Casual Friday Menu: Roasted Cauliflower Soup (Dairy Free and Whole30 options)

Let’s Dish About This Soup:

This creamy soup is rich and satisfying. Great served alone, in a bread bowl, or as a side dish, and it’s chock full of nutrients. Cauliflower is high in folate, fiber, Vitamin C, and contains many phtyochemicals common in plants that are members the cabbage family. Cauliflower is also high in sulforaphane, a nutrient known to have anti-cancer benefits. All this and  low carb, so even my keto friends can indulge.

How to Make Roasted Cauliflower Soup (with Whole30 option):

Simply roast cauliflower, shallots and garlic cloves in the oven, place in a blender with broth, and your choice of milk (including dairy free options) and blend until smooth. Yep, it’s that easy!

  • 12 cups cauliflower florets (approx 3 small heads of cauliflower)
  • 4 shallots, peeled and quartered
  • 2 cloves garlic cloves, peeled
  • 2-3 Tablespoons olive oil
  • Sea salt and freshly ground pepper
  • 4 cups chicken or veggie broth, divided
  • 2 cups milk or half and half. For dairy free: plain almond milk, or coconut cream
Optional Garnishes:
  • chopped parsley, roasted pine nuts, sliced mushrooms
  1. Preheat oven to 450 and place oven rack in center position.

  2. Cut cauliflower into florets and slice shallots.
  3. Place florets, shallots and garlic gloves on parchment paper, drizzle with olive oil, toss making sure everything is covered in oil

  4. Generously sprinkle with sea salt and pepper. Toss again.

  5. Place in oven and roast for 30 minutes (or until golden), turning with spatula every ten minutes. Remove from oven.

  6. Reserve two cups of cauliflower for later. You may need to do this next part in two batches of your blender is small: Place the remaining cauliflower, garlic and shallots into a blender.Add 3 cups of broth to blender (reserve the last cup for later)

  7. Blend until smooth. Pour into a stock pot and place on medium heat.

  8. Add milk, half and half or non dairy milk to pot. If using almond milk you may need less than recipe calls for as almond milk is somewhat thin. Whisk until smooth while continuing to heat.

  10. Chop reserved cauliflower. When hot, spoon soup into bowls, add remaining chopped cauliflower florets to top the soup, garnish as desired (see suggestions above)
