How to Make this Soup

This soup is very easy to make with just a handful of simple ingredients. You’ll start by getting the roasted garlic in the oven.

Simply cut the tops off, drizzle with a little olive oil, wrap in foil and roast away until soft and fragrant. This usually takes about 30 minutes. I used two whole bulbs. Like I said, this soup is for garlic lovers!

After you’ve roasted the garlic, everything gets cooked up in a soup pot then blended and that’s it!

This creamy roasted garlic cauliflower soup is low in fat and carbs but packed with flavour and nutrition. Once the garlic is roasted, it can be ready in about 20 minutes. It’s thick, creamy, rich in flavour and perfect for dunking crispy bread in.
