Roasted Cauliflower Soup

Something special happens when you roast vegetables……the sugars caramelize and the flavors intensify creating an entirely new flavor profile. I have been roasting vegetables for many years, and when I just want a simple side dish, I’ll toss my prepared vegetables with a little olive oil and seasonings and pop them into a very hot oven to roast. Some of my favorite vegetables to roast are broccoli, cauliflower, Brussels sprouts, and winter squash.

I had a big bowl of leftover roasted cauliflower in the refrigerator this past week and decided to turn it into a creamy soup. I added in some sautéed onions and garlic, simmered it all in chicken broth, and then pureed the soup into a bowl of creamy goodness. I like to garnish my soups, especially creamy ones, as they can look a little boring without a little added something.

To garnish this soup, I fried up a little finely diced pancetta along with some coarse whole grain breadcrumbs to add texture and interest but you could garnish your soup with just about anything from a dollop of sour cream, to some chopped green onions or chives. You can puree your soup in a blender, food processor, or with a hand wand depending on what you have on hand. I left my soup quite thick, but feel free to add a little additional water or broth to thin your soup if you prefer.

Buon Appetito!
