Creamy Cauliflower Bisque

Creamy cauliflower bisque has been in the recipe queue for a long time, but a recent dinner boosted it to the top. Executive chef Ali Monge of the Dining Room at Little Palm Island presented a wonderful dish that proved how good it can be. So good, it inspired me to create my own.

Soup, Bisque or Burgoo?

Soup is easily identified by its broth and texture, but the line begins to blur as it becomes “hearty”. Bisques fall between soups and stews like my burgoo that will hold a spoon standing straight up.

A silky smooth bisque requires the use of a thickener. Traditional old style bisques use rice, modern bisques use roux, potatoes or creams. I chose potatoes to add the starch necessary for a nice bisque. Choice of potato is important and white potatoes best preserve a pure white color in the finished dish. Locally however they have been replaced completely by russets, golden or rose potatoes.

Russets are tasty and white, but they leave an ever so slight grainy texture in finished bisque regardless how long I blitzed them. Rose gold potatoes taste delicious and creamy, but will give the bisque a light golden tint. So, pick your poison, but get ready for a delicious bisque!

Making Cauliflower Bisque

Begin with a large head of cauliflower, trim away the green leaves and cut it up into large florets. Peel and cut the potatoes into similar size chunks.

sweating onions

Melt the butter in a large pot with the olive oil, add the chopped onion and saute, stirring constantly  for 2-3 minutes until they soften and begin to turn translucent. Add the garlic and cook 1 minute more. Do not allow them to turn color.

boiling the veggies

Pour in the vegetable broth and milk. Add the potatoes and cauliflower to the pot and raise the heat to bring it to a vigorous boil. Reduce the heat and low simmer for 20 minutes until the vegetables are soft.
