Ingredients

For the Soup

  • 6 sweet yellow onion (not regular onions)
  • 4 tbsp butter
  • 2 tbsp olive oil
  • 3 cloves garlic (minced)
  • 1 tsp dried thyme
  • 2 tsp salt
  • 1/2 tsp black pepper
  • 1/2 cup dry sherry
  • 6 cups low sodium beef broth

For the cheese and bread topping

  • 1/2 loaves French bread (sliced)
  • Shredded Fontina cheese

Instructions

Caramelize the onions

  • Slice the sweet yellow onion into strips.
  • In a heavy-bottomed pot, heat butter and olive oil over medium-high heat. Then add in all of the sliced onions. Cook the onions for about 15-20 minutes while constantly stirring.
  • Once the onion has softened, add the minced garlic, dried thyme, salt, and pepper.
  • Drop the heat to medium and let the onion cook with the spices for about 4 minutes.

Add the wine and beef broth

  • Bring the heat back to high and add the dry sherry. Stir for about 3 minutes to let the wine cook out.
  • Pour the beef broth into the pot and let it simmer for another 15 minutes.
  • Meanwhile, place the sliced French bread onto a baking sheet and bake at a 360 degrees Fahrenheit until golden brown.

Pour soup into oven safe bowls

  • Fill each oven-safe soup bowl with the soup and place 2 pieces of French bread on top of the soup. Then sprinkled a layer of freshly shredded fontina cheese.
  • Broil the soup in the oven until the cheese becomes bubbly and golden brown.

Notes

Note: if you don't have oven-safe soup bowls, the soup can still be enjoyed without the bread and cheese
