Roasted Cauliflower Soup

January being the soup month I thought of posting one more delicious soup. This soup is extremely good and creamy.  Roasting cauliflower gives it an incredible nutty flavor.

Ingredients:
 1 head cauliflower, cut into small florets
 2 tablespoons roasted garlic-flavored extra-virgin olive oil

Preheat oven to 450 degrees F (230 degrees C).
Place the cauliflower in a small roasting pan. Drizzle with oil and season with nutmeg, garlic powder, salt, and pepper; toss to coat.
Roast the cauliflower in the preheated oven stirring every 10 minutes until golden brown and tender, 30 to 40 minutes. Remove from the oven and set aside.

Slowly pour the chicken broth and milk into the pan. Mix with a wire whisk until all of the flour is dissolved. Bring to a boil while stirring continuously until it thickens, then reduce heat to low. Stir in the  the roasted cauliflower. Serve as is, or blend half and recombine with the rest of the soup for a thicker consistency.Add thyme before serving.
