Leftover Chicken & Mushroom Soup with Crispy Skin Crostini

Notes from Nourishible editors

Written by our recipe team from the video and the method above.

• Quantity · Step 4: The video gives no amount for the mushrooms; as an estimate, about 250g suits four servings alongside one onion.
• Technique · Step 4: Let the onion and mushrooms go properly dark before the flour goes in; the browning is where the soup gets its savoury depth, so don't rush it.
• Equipment · Step 7: The video uses a hand blender; a jug blender works too, in batches, with the soup cooled slightly first.
• Swap · Step 8: No double cream? A spoonful of crème fraîche is another rich dairy topping and gives a similar swirl.
