Prep time: 15 minutesCook time: 1 hourServes: 4
Ingredients
4 large yellow onions, thinly sliced
3 tablespoons unsalted butter
2 tablespoons olive oil
1 teaspoon salt
1/2 teaspoon fresh ground black pepper
1/4 teaspoon sugar
1 tablespoon all-purpose flour
6 cups beef broth

Salt and pepper to taste
8 slices French baguette
2 cups Gruyère cheese, grated

1. In a large pot, melt the butter with olive oil over medium heat.

8. Place bowls under the broiler until cheese is melted and bubbly, about 3 minutes.
