Our plant-based roasted cauliflower soup is nutty, toasted and sweet with the perfect amount of earthiness in every bowl. Top it with breadcrumbs, chives and cauliflower florets with a drizzle of olive oil and serve hot on a cold day.

During the summer months, one of our favourite ways to eat our veggies is straight off the barbecue or the smoker. Grill marks, charred skin and the natural sweetness of vegetables from bok choy to mushrooms to asparagus to roasted peppers. Ahh, summer… slather us in sunscreen and pass us a cold one.

During the winter months, our favourite way to prepare vegetables (and keep the condo warm) is roasting them in the oven, especially beets, cauliflower, carrots, garlic heads and butternut squash. The dry heat of the oven caramelizes the natural sugars in vegetables, bringing out an elevated and layered depth of flavour. Ahh, roasted veggies… grab the Vitamix, pour in some broth and make soup. And soup is exactly what we made, roasted cauliflower soup.

Ingredients

Vegetable Stock

  • 1 lb carrots
  • 1 lb tomatoes
  • 1 1/2 lbs sweet onions
  • 2 tbsp olive oil
  • 1 lb celery
  • 6 cloves garlic
  • 4 whole cloves
  • 12 whole peppercorns
  • 1 bunch bunch parsley (about 1 cup)
  • 2 whole bay leafs
  • 12 cups water
  • 1 + 1/2 tsp salt

Soup

  • 1 medium onion (diced)
  • 3 heads garlic
  • 1 large head cauliflower
  • 5 tbsp olive oil
  • 1 cup white wine
  • 1 + 1/2 tsp salt
  • 1 tsp fresh ground pepper
  • 1 cup bread croutons
  • 3 tbsp chives (finely chopped)

Instructions

No. 1 | Preheat your oven to 450°.

No. 2 | Roughly chop carrots, tomatoes and onions into 1” chunks. Place in a roasting pan and drizzle with olive oil and ½ tsp salt. Give it a quick mix and place in the oven for 60 mins, mixing it every 20 minutes or so.

No. 3 | Cut your celery into 1” pieces and place in large stock pot with garlic, whole cloves, peppercorns, parsley, bay leaves, water and 1 tsp salt. Add the roasted vegetables and bring to a rapid boil. Lower to medium low heat so it is still lightly boiling and reduce liquid by half, about 60-90 minutes. Strain the stock through a sieve and discard vegetables.

No. 4 | While the stock is reducing, chop the cauliflower into small florets. Place in the same roasting pan you used for the vegetable stock and drizzle with 2 tbsp olive oil and ½ tsp salt. Place in oven and roast for 60 minutes, mixing every 20 minutes.

No. 5 | Cut the tops off of the 3 heads of garlic. Place them on a piece of aluminum foil large enough the wrap them. Drizzle the garlic and a tsp of olive each. Wrap tightly and place in the oven once you stir the cauliflower the first time.

No. 6 | Remove the cauliflower and the garlic from the oven. They should be brown and caramelized. Once cool enough to handle, squeeze the roasted garlic into a small bowl and remove any skins.

No. 7 | Sautee the diced onions in your soup pot in 2 tbsp olive oil for 3 minutes. Add the cauliflower and garlic. Cook for about 5 minutes then add the white wine to deglaze the pan.

No. 8 | Pour in the vegetable stock (should be about 6 cups). Bring the soup to a light boil, then reduce heat to simmer. Add salt and pepper and cook for 30 minutes.

No. 9 | Blend the soup using an emulsion or countertop blender. Adjust seasoning to taste.

No. 10 | Serve with a sprinkling of chives and croutons.

Notes

If you are tight for time you can use store bought vegetable or chicken stock and start with step 4
