Then cut each in half lengthwise, slicing through the root end. Place onions cut-side down on a chopping board, then thinly slice into half-moon pieces. Sliced onions should measure about 5 cups.

2. Heat Butter


and oil in a large wide saucepan over medium heat. Add onions and sprinkle them with sugar. Cook, uncovered and stirring often, until very soft and caramelized – about 15 minutes. Reduce heat if they brown too quickly.

3. Add Broth

wine , Dijon mustard and seasonings. Scrape up brown bits from pan. If using a carton of broth, add 1/2 cup of water. For canned, add 3 cups of water. Bring to a boil over high then cover and simmer over medium low for 30 minutes to develop flavor. Discard bay leaf and thyme springs.

4. Place Oven Rack


in top half of the oven. Cut bread into 8 slices, each about 1/2 inch thick. Butter both sides of each and toast on a baking sheet until slightly golden – about 2 minutes per side.

5. Place Oven-Safe Soup Bowls

on a baking sheet. Ladle in soup. Top each bowl with 2 slices of toasts. Sprinkle with cheese. Place sheet in oven and broil until cheese is slightly bubbly – 2 to 4 minutes. Serve immediately.

If making ahead, soup (without toasts) will keep well in the fridge for 3 days or freeze for up to 2 months and flavor will improve as it sits.
