Ingredients
  

  • 3 large sweet yellow onions (thinly sliced)
  • 3 tbsp unsalted butter (divided, for caramelizing)
  • 1 tbsp olive oil
  • 1/4 tsp kosher salt
  • 2 cloves garlic cloves (finely minced)
  • 1 tbsp fresh thyme leaves (chopped)
  • 1/2 cup rich halal beef bone broth (for deglazing)
  • 1 tbsp Worcestershire sauce (halal / anchovy-free)
  • 8 slices thick-cut artisan sourdough bread
  • 4 tbsp softened unsalted butter (for bread)
  • 1 1/2 cups Gruyère cheese (freshly shredded)
  • 1 cup Swiss or fontina cheese (freshly shredded)
  • to taste freshly cracked black pepper

Method
 

  1. Heat 2 tbsp butter and 1 tbsp olive oil in a wide skillet over medium-low heat. Add sliced onions and kosher salt; cook slowly for 25-30 minutes until deep golden-brown.
  2. Add minced garlic and fresh thyme; cook for 1 minute. Pour in beef bone broth and Worcestershire sauce to deglaze the fond, simmering for 3-4 minutes until reduced to a glossy onion jam.
  3. Generously butter one side of each sourdough bread slice. Place 4 slices butter-side down on your workstation.
  4. Layer each slice with shredded Gruyère, warm caramelized onions, freshly cracked black pepper, and shredded Swiss cheese. Top with remaining bread slices butter-side up.
  5. Heat a heavy cast-iron skillet over medium heat. Place sandwiches in skillet, press gently with a spatula, and griddle for 4 to 5 minutes until crispy and golden.
  6. Flip carefully and griddle the other side for 3 to 4 minutes until the crust is shattered-crisp and cheeses are completely melted and gooey. Serve warm immediately!
