In a saucepan, melt the butter and add the shallots with a pinch of salt.
Once translucent, add the chestnuts then pour in the chicken bouillon cube with the water, and cream, salt, and pepper.
Cover, bring to the boil then cook for 15 minutes over low heat. Mix everything in a blender.
Notes
This French chestnut soup can be made completely ahead of time and refrigerated for up to 2 days. Reheat, adding the cream just before serving. Bon appétit!
