The older the turnip, the longer it takes to cook and the more strongly flavored and bitter it is. Look for small, young turnips, they'll be only slightly bitter and actually quite sweet.
- 6 Tbsp unsalted butter
- 4 medium onions, thinly sliced
- 3 pounds fresh, young turnips, peeled and thinly sliced
- 1 1/2 pounds of Russet baking potatoes, peeled and thinly sliced
- 6 Cups of chicken stock
- 1/4 teaspoon freshly grated nutmeg
- 2 Tbsp chopped fresh parsley for garnish
1 Sauté the onions in butter: In a large, heavy, thick-bottomed pot, melt the butter on medium heat until it foams. When the butter foam subsides, add the onions and cook until translucent but not browned, about 5 minutes.
2 Add turnips, potatoes, salt, cover and cook: Add the sliced turnips and potatoes and stir to coat with the butter. Add 2 teaspoons of salt, cover and reduce the heat to low. Cook, stirring occasionally, until the turnips and potatoes are tender, about 20 minutes.
3 Add chicken stock: Add the chicken stock and increase the heat to bring to a simmer. Cover partially and cook over medium heat until the turnips and potatoes are very tender, about 10 minutes.
4 Purée the soup: Working in batches, purée the soup in a blender until completely smooth. Return the soup to the pot and season with salt and freshly grated nutmeg. Ladle the soup into shallow bowls and garnish with the parsley before serving.
