Serves: 8
Ingredients
*Ingredients currently available at the farmers’ market
● 2½ pounds yellow onions*
● 3 Tablespoons unsalted butter
● 2 Tablespoons olive oil
● 1 teaspoon salt
● Freshly ground pepper
● ½ teaspoon sugar
● 8 cups of beef, chicken, or vegetable broth
● 3 Tablespoon flour
● ½ cup white wine*
● 8 baguette slices, toasted*
● 1½ cup to 3 cups of shredded Gruyere cheese (1/4 to ½ cup per serving)
Instructions
1. Cut onion into thin evenly-sized half-moon slices. Should yield about 6 cups of onion slices.
2. Melt butter with oil in a pan over medium-low heat.
3. After the butter foams up and then settles down, add the onions and stir to coat with the butter.
4. Cover the pan and cook for 15 minutes on low heat.
5. Remove the lid. The onions should have wilted down. Stir in salt, a generous amount of pepper, and sugar.
6. Turn the heat up to medium and cook, uncovered and stirring every few minutes, until the onions are deeply browned.
7. As the onions turn a deep walnut color, heat the broth in a separate pan.
8. Add 3 Tablespoons flour to the caramelized onions and cook, stirring for about 1 minute.
9. Add the hot broth to the caramelized onions and bring to a boil. Add wine if using. Lower the heat and partially cover the pan. Cook gently over low heat for at least 1 hour or until the broth is slightly reduced.
10. Heat the oven to 350 degrees. Divide the soup between oven-safe bowls or use a deep casserole dish. Top each with a slice of toasted baguette and sprinkle grated cheese in a thick layer over the bread and up to the edge of the bowl.
11. Place the bowls on a baking sheet or in a casserole dish, if not using oven-proof bowls. Bake until the cheese is thoroughly melted.
12. Turn the oven from bake to broil and broil the soup for 1 to 3 minutes or until the cheese is browned and bubbling. Remove from the oven and let cool for a few minutes before serving.
Notes:
Top with minced shallots, onions, or crispy bacon. Add thyme with wine and sprinkle over the soup before baking.
