Roasted cauliflower soup

The crispy topping of roasted cauliflower and croutons really makes this velvety soup unique. This is Tyler Florence's recipe for roasted cauliflower soup from his cookbook Tyler's Ultimate, which has a lot of great classics. Tyler calls for copious amounts of butter (3/4 cup!) and I'm sure that tastes lovely and very restaurant-like. To lighten things up, I reduced the butter content to four tablespoons in total and I thought the soup still tasted nice and creamy. I used two tablespoons of butter in the soup (instead of the recommended half cup/one stick!). For the topping, I used two tablespoons each of olive oil and butter instead of four tablespoons of butter. Lastly, I made my topping with baguette instead of brioche because that's what I had on hand.
