Cheesy Cauliflower Potato Soup

~Cheesy Cauliflower Potato Soup ~

Making purée, er, soup doesn’t get simpler than this. It began as a purée. I made a light and fluffy Cauliflower and Potato purée to accompany a stew this week.  However there was so much purée left over, I thinned the remainder with extra chicken stock and renamed it soup. It’s clearly all about the cauliflower, thickened with potato and spiked with a little garlic and piquant Pecorino cheese. Add just a little stock and you’ll have a light and airy side dish. Add more stock and you’ll have a satisfying winter soup. And since it’s the holidays I fancified both purée and soup with a generous pinch of gifted truffle salt sprinkled over the top.

Cheesy Cauliflower Potato Soup
Serves 6

2 yukon gold potatoes, about 1 pound
1 medium head cauliflower
4 garlic cloves
3 tablespoons unsalted butter
1/2 cup finely grated Pecorino Romano cheese
1 quart chicken stock
Salt and freshly ground black pepper to taste
Fresh thyme leaves
Truffle salt (optional)

Peel the potatoes and cut in 1-inch chunks. Cut the cauliflower florets and core in 1-inch pieces. Peel garlic. Smash 3 of the cloves and mince 1 clove. Place potatoes, cauliflower and smashed garlic cloves in a large pot. Cover with water. Add 1 tablespoon salt. Bring to a boil, then reduce heat, cover and simmer until the vegetables are very tender, about 25  minutes. Drain. Transfer half of the vegetables and butter to the bowl of a food processor. Puree until smooth. Add remaining vegetables. Puree again. Return vegetables to soup pot. Add minced garlic. Add chicken enough chicken broth to achieve desired consistency (the soup should not be too thick). Bring to a simmer and add cheese, stirring to incorporate. Season to taste with salt and pepper. Serve with additional cheese and fresh thyme as a garnish. Optional: Sprinkle with truffle salt.
