🥘Ingredients

For the Soup

4 large yellow onions, thinly sliced
3 tablespoons unsalted butter
1 tablespoon olive oil
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon dried thyme
1/2 cup dry white wine
4 cups beef broth
1 cup water

For the Topping

8 slices French baguette, 1 inch thick
1 1/2 cups shredded Gruyere cheese
1/2 cup grated Parmesan cheese

👨‍🍳Directions

1Preheat the oven to 400 degrees Fahrenheit.
2Melt the butter with the olive oil in a large oven-safe pot over medium heat, then add the sliced onions, salt, pepper, and thyme.
3Cook, stirring occasionally, until the onions are deep golden brown and softened, about 25 to 30 minutes.
4Pour the white wine into the pot and stir, scraping up any browned bits from the bottom.
5Let the wine simmer until mostly evaporated, about 2 minutes, then add the beef broth and water.
6Bring the soup to a gentle boil, then remove the pot from the heat.
7Place the baguette slices on top of the soup in a single layer, pressing them down slightly so they absorb some liquid.
8Sprinkle the shredded Gruyere and grated Parmesan evenly over the bread slices, covering them completely.
9Transfer the pot to the preheated oven and bake until the cheese is melted, bubbly, and golden brown, about 15 to 20 minutes.
10Let the soup cool for 5 minutes before serving, as the pot will be very hot.

For a deeper flavor, let the onions caramelize slowly over medium-low heat. Use a dry white wine like Sauvignon Blanc or Pinot Grigio. You can substitute Swiss or mozzarella cheese for the Gruyere if needed.
