This Roasted Sweet Potato and Leek Soup is a lovely gently seasoned soup. Made with roasted sweet potatoes, a leek, a head of roasted garlic, and some curated seasonings, this is a comforting soup, especially when served with fresh bread (plain, crusty, or garlic), rolls, focaccia, biscuits, or savory crackers. Whether enjoyed for lunch or a light supper, this thick and creamy soup makes for a comforting meal.  The soup freezes and reheats well, too, so is handy to have on hand in the freezer for when needed.
