1 Tbsp. unsalted butter
1 medium onion, chopped
2 celery stalks, chopped
1 garlic clove, minced
3 cups water (or veggie stock)
1 pound parsnips, peeled, cored*, diced
Salt and pepper
Melt the butter in a medium saucepan over medium-low heat. Sauté the chopped onion and celery for 4 to 5 minutes until soft and translucent. Don't let the vegetables brown. Add the garlic and sauté for 15 seconds until fragrant. Add the water or stock and the parsnips. Bring to a boil. Reduce the heat and simmer until the parsnips are soft, 15 to 20 minutes. Let cool and purée in a blender or with a stick blender until perfectly smooth. Season with salt and pepper. Serves 2 or 3. The recipe can be doubled (just be sure to purée the soup in half-batches if using a blender).
*Some parsnips have a woody central core that runs from top to bottom. To remove it, I usually just slice the peeled sides right off the core, which is a slightly different color. (Then chop up the sides and discard the core.) But if you're not sure exactly where or how big the core is, you can also quarter the parsnip the long way. Then you can see it a lot better. Just trim along the interior edge of each quarter with a paring knife to remove it.
