This soup manages to be both comforting and healthful. The broccoli, leek, and potato base comes together quickly, andwith an immersion blenderit only takes one pot. After pureeing, youll stir in a little sour cream and sharp cheddar cheese to boost the body and richness. Quickly baked cheesy croutons double down on the deliciousness. Flavor tip: like most soups, this one tastes even better the next day.
