  • 1 tbsp olive oil

  • 3 medium onions, sliced thinly, about 3 1/2 cups

  • 1/2 900-mL carton low-sodium beef broth

  • 1 sprig thyme

  • 1/4 cup dry sherry, optional

  • 4 tsp Dijon mustard

  • 8 slices rye bread

  • 4 slices gruyère, or swiss cheese, about 120 g


  • Heat a large non-stick frying pan over high. Add 1 tsp oil, then onions, broth and thyme. Cook, uncovered, stirring often, until liquid is reduced, about 15 min. Add sherry and continue cooking until absorbed, about 5 more min. Remove thyme.

  • Spread Dijon on 4 slices of bread. Top each slice with about 1/3 cup onion mixture and 1 cheese slice. Top with remaining bread.

  • Wipe pan clean. Heat over medium. Brush pan with 1 tsp oil. Cook 2 sandwiches at a time, about 2 min per side. Repeat with remaining oil and sandwiches.
