Ingredients

  • 2 Tbsp olive oil
  • 1 Tbsp Butter
  • 3 lbs yellow onions thinly sliced
  • 1/2 cup cognac
  • 2-3 sprigs Fresh thyme
  • 6 cups Beef stock
  • 1 tsp beef base I use better than Bouillon
  • 8 slices ciabatta bread, thick sliced
  • Salt and Pepper to Taste
  • Gruyere Cheese for topping sliced or grated is fine

Instructions

  • Melt butter and olive oil in a large dutch oven over medium heat. Add onions and sprinkle with salt and pepper. Cook onions until translucent and soft. Turn down heat to med-low and cook until onions are thoroughly caramelized, about 20 minutes. Add cognac for 30 seconds and stir to deglaze the pot. Add fresh thyme to taste and more ground pepper, if desired. Pour in beef stock and base and heat to simmer. Cover and reduce heat, simmer for 30 minutes.
  • Heat oven to 325 degrees F. Brush each side of the bread slices with a bit of olive oil and place on baking sheet. Cook the slices for 15 minutes in the oven on each side (30 minutes total).
  • Pour the soup into oven safe bowls or ramekins, top with bread and cover entirely with gruyere cheese. Place bowls on a cookie sheet and place under broiler until cheese melts and is bubbly.
