Tasty and creamy and rich this is a soup for a cold winter day. Easy to make, it is a wonderful dish to keep in your back pocket for those days when you want to eat well but not necessarily spend all day in the kitchen.
Ingredients
1 tablespoon unsalted butter
1 large leek, white and light green parts only, thinly sliced
5 garlic cloves, crushed
2 1/2 pounds celery root, peeled and cut into 1-inch dice (8 cups)
One 2-inch chunk of Parmigiano-Reggiano cheese (1 ounce), plus 1/4 cup freshly grated cheese
2 cups chicken stock or low-sodium broth
1/2 cup walnuts
1/4 cup extra-virgin olive oil
1/2 cup coarsely chopped parsley
I/2 cup pomegranate seeds
1/2 cup heavy cream
Kosher salt
Pepper
Instructions
In a large saucepan, melt the butter. Add the leek and garlic and cook over moderate heat, stirring occasionally, until softened, 5 minutes. Add the celery root, Parmesan chunk, stock and 5 cups of water and bring to a simmer. Cover and cook over moderately low heat, stirring occasionally, until the celery root is tender, 40 minutes.
Meanwhile, preheat the oven to 375°. Spread the walnuts in a pie plate and toast for 5 to 7 minutes, until golden. Let cool, then finely chop and transfer to a bowl. Add the oil, parsley and grated cheese and mix well.
In a blender, puree the soup in 2 batches until very smooth. Pour into a clean saucepan and stir in the heavy cream; season with salt and pepper and reheat if necessary. Serve topped with the walnut gremolata and pomegranate seeds.
