  • 3 tbsp organic, grass-fed unsalted butter
  • 4 yellow onions thinly sliced
  • 3 cups low sodium beef broth
  • 1 tbsp balsamic vinegar
  • 1 tsp dried thyme
  • 1 tsp sea salt plus more to taste
  • 1/2 tsp pepper to taste plus more to taste
  • 1/2 cup low sodium chicken broth
  • 1 tbsp chickpea flour
  • French baguette sliced into 1/2-inch slices (whole grain if possible)
  • 4 slices provolone cheese
  • 8 oz grated Gruyere cheese


  1. Melt butter in a deep stock pot or Dutch oven over medium-high heat.
  2. Add onions and cook, stirring occasionally, until tender and browned, about 15-20 minutes.
  3. While onions are cooking, heat the oven broiler.
  4. Add beef broth, white wine, balsamic vinegar, thyme, salt, and pepper and bring to a simmer.

  5. In a small bowl, combine the chicken broth with the flour and then add to the onion mixture. Cook for an additional 10 minutes.
  6. Line a baking sheet with tin foil and place the baguette slices down flat. Use 2-3 per person, depending on the size of your serving bowl. Place into oven and broil for 1-2 minutes per side, until golden brown. Remove from oven but leave broiler on.
  7. Ladle the onion soup evenly into 4 oven-safe serving bowls, starting with the onions and then with the liquid.
  8. Place 2-3 baguette slices atop each bowl, followed by a slice of provolone cheese, and then topped with the shredded gruyere cheese.
  9. Place bowls on the baking sheet you used for the baguettes and broil until the cheese is bubbly and golden, about 5 minutes.
