This velvety, rich dish is like chestnut soup with Southern flair, thanks to the delicious (and crunchy) addition of a protein powerhouse ingredient: toasted pecans. We know that pecans are incredibly delicious in desserts and on top of a fresh, crisp salad, but this recipe proves how versatile pecans can be in a savory bowl of soup. Although the star of the meal is the pecans, the celery, onions, and potatoes shine here, too. It's fairly easy to make and ready in about an hour.
