One of the soups that brings me the most comfort when the weather is cold is classic French onion soup. It’s a favorite in this house too, despite the onions which are normally a turnoff for the kids. Tender in the soup, the hunks of baguette soaking underneath the layer of melted cheese are just too irresistible to anyone. It’s a soup I’ll make any day of the week yet is perfectly fit for company too!
