There’s something deeply grounding about turning simple vegetables into a nourishing bowl of soup. This roasted broccoli soup was born on a quiet evening when I wanted comfort — but not heaviness. Roasting the vegetables first transforms them completely: broccoli becomes nutty and rich, carrots turn sweet, and onions melt into the background.
This is the kind of vegan broccoli soup I make when I want something wholesome, deeply flavorful, and easy enough for a weeknight — yet impressive enough to serve to guests. No cream, no dairy, just vegetables doing what they do best.
