Ingredients

  • 1 tablespoon olive oil 
  • 1 tablespoon unsalted butter
  • 2 yellow onion, peeled and thinly sliced
  • Salt
  • 8 ounces cremini mushrooms, thinly sliced
  • 5 cups of water 
  • 6 ounces Gruyere cheese, grated
  • French bread, sliced

Instructions

  1. To a medium pot, set over medium-low heat, add the olive oil, butter, onions and a few pinches of salt. Cook until softened, about 5 minutes. Spread the onions out into an even layer on the bottom of the pan. Stirring occasionally, cook for about 10 to 15 minutes until caramelized. Turn the heat to medium-low and cook for an additional 15 minutes, again, stirring occasionally. Add the mushrooms; continue cooking until the mushrooms are softened, about 10 minutes. Add the water and bring to a gentle simmer. Cook for about 5 to 7 minutes. Give it a taste and adjust the salt to your liking.
  2. Divide the soup amongst the soup bowls. Top with slice of bread and a huge handful of shredded cheese. Transfer to a baking sheet and place it under a broiler until the cheese is melted and bubbly, about 5 minutes. Serve immediately.
