For good reason, bowls of French onion soup hold a sacred spot on bistro menus worldwide. How can you go wrong with slowly cooked caramelized onions, hearty broth, crusty bread and Gruyère cheese? Nine feet of snow fell in Boston this year and this simple to prepare soup made its way onto the table more than usual. Yes, the herbs de Provence are unorthodox, but, they just seem to work. After a slog home in bitter cold conditions, the smell of simmering French onion soup causes diners to arrive at the table before the cheese has a chance to blister in the oven.

serves 6


  • 6 large yellow onions, thinly sliced
  • 5 cups water
  • 1 tablespoon veal or beef demi-glace
  • 2 tablespoons chicken demi-glace
  • 2 tablespoons unsalted butter
  • Olive oil
  • 2 tablespoons herbes de Provence
  • 2 cups Gruyère, shredded
  • Day old baguette or petite French square toast crackers


  1. In a large dutch oven on medium low heat, add olive oil to coat bottom of pan. Add sliced onions and cook slowly until golden. If skillet gets dry, add more olive oil. This takes time, at least the better part of an hour to get the rich golden color.
  2.  When onions are ready, add water, both demi-glaces, butter, and herbes de Provence and bring broth to a simmer. Cook for 10 minutes.
  3.  Divide soup into oven safe bowls. When ready to eat, place bread or French toast crackers on top of soup bowls.
  4.  Divide the shredded Gruyére over top of each bowl (be generous and cover the bread all the way to the edges of the bowls so the cheese melts over sides of bowls).
  5.  Place bowls on 1/2 sheet baking tray and place in the oven. Watch carefully until the cheese is bubbly and brown. Remove from oven and serve immediately.
