This is part of my 2021 Christmas Eve Dinner, a gourmet feast I have made every year since 2010 (except 2020). I started this tradition with my wife and in-laws, and it has grown to include my children and my parents when they moved to be closer to me in 2016. This year's soup is French Onion.
- 4 tablespoons unsalted butter
- 1 tablespoon vegetable oil
- 3 pounds Vidalia (or sweet) onions (about 5 medium), halved lengthwise and thinly sliced
- 3/4 teaspoon salt 1/2 teaspoon freshly ground black pepper
- 3/4 teaspoon granulated sugar
- 1 cup dry white wine
- 2 tablespoons all-purpose flour
- 6 cups beef broth
- 1 teaspoon Worcestershire sauce
- 1/2 teaspoon dried thyme
- 2 bay leaves
- 1 small baguette, cut into 1/2-in slices
- 1 tablespoon dry sherry
- 8 ounces Gruyère cheese, grated (about 2 heaping cups; look for one imported from Switzerland)
- 1/2 cup grated Parmigiano Reggiano
- In a large Dutch oven or soup pot, melt the butter over medium heat. Add the oil, onions, salt,
pepper, and sugar. Cook, uncovered, stirring occasionally with a wooden spoon, until onions are
deep golden brown and caramelized, 45 to 55 minutes. In the beginning, you will only need to stir
the onions only occasionally. As they start to brown midway through cooking, you will need to stir
them frequently, scraping the fond (the brown particles) from the bottom of the pan. If the onions are
browning too quickly, reduce the heat slightly or add a few tablespoons of water to deglaze the pan
and continue cooking.
- Add the wine and raise the heat to high. Cook, stirring with a wooden spoon to scrape any fond from the bottom of the pan, until almost all of the liquid has evaporated and the onions are jammy, 8 to 10 minutes.
- Add the flour and cook, stirring constantly, for one minute.
- Add the broth, Worcestershire sauce, thyme, and bay leaves to the pot. Bring to a boil, reduce the heat to a simmer, and cook, covered, for about 30 minutes.
- While the soup simmers, preheat the oven to 400°F and set an oven rack in the middle position.
- Arrange the baguette slices in a single layer on a baking sheet and bake until the bread is dry, crisp, and golden at edges, about 10 minutes. Set aside.
- When the soup is finished, remove the bay leaves and add the sherry; taste and adjust seasoning if necessary. If the soup needs a deeper flavor, try a few shakes of Worcestershire sauce. If it's not quite sweet enough, add 1/4 teaspoon sugar.
- Adjust an oven rack 6 inches from broiler element and heat broiler. Set individual broiler-safe crocks on a baking sheet and divide the hot soup among the crocks (be sure the soup is very hot as it won't warm up much in the oven).
- Top each crock with 1 or 2 baguette slices (do not overlap slices) and sprinkle evenly with Gruyère
and then Parmigianno Reggiano.
- Slide the crocks into the oven and broil until the cheese is melted and bubbly around edges, 3 to 5 minutes. Let the crocks cool for a few minutes before serving.
(Alternatively, if using regular soup bowls: Top each toast slice with some cheese and return to
broiler to melt, about 2 minutes more. Divide the soup among bowls and top each serving with two
