  • 4 large onions, sliced
  • ¼ cup butter

  • 1 tsp. baking soda
  • 1 Tbs. minced fresh thyme
  • ¾ cup beef broth (optional)

  • 1⅓ cup shredded Gruyere or Swiss cheese


  1. In large skillet over medium-high heat, cook onions in butter, covered, 5 min., stirring occasionally. Uncover; stir in sugar, baking soda and thyme. If pan seems dry, add a few Tbs. beef broth or just enough to moisten. Cook another 10 min. or until golden brown, stirring occasionally. Season to taste with salt and pepper.
