Vegetarian French Onion Mushroom Soup

Ingredients

• 1 tablespoon olive oil 
• 1 tablespoon unsalted butter

• Salt
• 8 ounces cremini mushrooms, thinly sliced
• 5 cups of water 
• 6 ounces Gruyere cheese, grated

Instructions

1. 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.

   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.
