Best 5 Restaurant Style 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.

RESTAURANT-STYLE FRENCH ONION SOUP

Steps:

• Melt butter in a large soup pot over medium heat. Cook and stir onions, garlic, salt, black pepper, and thyme until onions are soft and brown, about 30 minutes. Pour in red wine and sherry; bring to a boil. Reduce heat to low and simmer until you can no longer smell alcohol cooking off, about 15 more minutes.
• Sprinkle onion mixture with flour and stir until coated; cook for 10 minutes. Pour in broth, stir to blend in flour, and simmer until slightly thickened, about 20 minutes.
• Preheat oven to 350 degrees F (175 degrees C) while soup is simmering. Arrange bread slices on a baking sheet and drizzle with olive oil.
• Toast the baguette slices in the preheated oven until golden brown, 12 to 14 minutes, turning the bread over halfway through cooking. Remove toast and set aside.
• Set an oven rack about 8 inches from the heat source and turn on the oven's broiler.
• Ladle soup into 6 oven-proof crocks, filling them about 3/4 full. Place 1 or 2 bread slices into the bowls and top each with a slice of Swiss cheese and a slice of provolone. Carefully place filled crocks onto a sturdy baking sheet.
• Broil soup until the cheese is browned and bubbling, 3 to 4 minutes.
