Best 8 Rustic French Onion Soup Recipes

FRENCH ONION SOUP

Steps:

• 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 ¼ 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 cheese toasts.)
• Make-Ahead Instructions: The soup can be made and refrigerated up to 3 days ahead (without toasts or cheese), or up to 3 months ahead and frozen. Toasts can be made (without the cheese) and kept sealed at room temperature for up to 3 days.

THE BEST FRENCH ONION SOUP

Steps:

• Melt the butter in a very large Dutch oven or pot over medium heat. Add the onions, bay leaves, thyme, 1 teaspoon salt, and a few grinds black pepper. Cook, stirring occasionally, until the onions are very soft and light golden-brown, about 1 hour. (The onions will begin to stick to the bottom of the pan and turn brown after about 30 minutes; just keep scraping them up and stirring them into the rest of the onions. If they are browning to quickly, lower the heat.)
• Add the wine to the pot, bring to a simmer and cook until it has almost completely evaporated, about 4 minutes. Add the beef broth and 1 cup of water, bring to a simmer and cook until the flavors come together and the soup is rich, about 45 minutes. Remove the bay leaves. Season with 1/2 teaspoon salt and a few grinds of black pepper. Keep the soup warm on a low burner or cool completely and refrigerate to reheat later. (The soup can be refrigerated for up to 2 days or frozen for up to 1 month.)
• Preheat the broiler. Place four soup crocks on a rimmed baking sheet and fill them about 3/4 of the way with hot soup. Float a slice of baguette on top of each and cover with 1/2 cup Gruyere. Broil until the Gruyere is golden brown (don't be alarmed if some soup bubbles out), 2 to 3 minutes.
