Best Roasted French Onion Soup Recipes

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.

ROASTED FRENCH ONION SOUP

Steps:

• In a large soup pot, heat vegetable oil. Add onions and garlic and sautee until lightly browned, 8-10 minutes Add all ingredients up to and including cloves, cover, bring to a boil. Lower heat and simmer for about 50 minutes, until vegetables are very soft. Strain through colander or sieve.
• Preheat oven to 375°F

Roast for 45 to 50 minutes, stirring every 15 minutes, until the onions have softened and lightly browned (cover with foil if getting too brown). Remove from oven, add wine to the baking pans, and stir well to deglaze.

FRENCH ONION SOUP: THE COOK'S ILLUSTRATED WAY

Steps:

• For the soup:.
• Adjust oven rack to lower-middle position and heat oven to 400°. Generously spray inside of heavy-bottomed large (at least 7-quart) Dutch oven with nonstick cooking spray.
• Place butter in pot and add onions and 1 teaspoon salt. Cook, covered, 1 hour (onions will be moist and slightly reduced in volume).
• Remove pot from oven and stir onions, scraping bottom and sides of pot. Return pot to oven with lid slightly ajar and continue to cook until onions are very soft and golden brown, 1 1/2 to 1 3/4 hours longer, stirring onions and scraping bottom and sides of pot after 1 hour.
• Carefully remove pot from oven and place over medium-high heat.
• Using oven mitts to handle pot, cook onions, stirring frequently and scraping bottom and sides of pot, until liquid evaporates and onions brown, 15 to 20 minutes, reducing heat to medium if onions are browning too quickly.
• Continue to cook, stirring frequently, until pot bottom is coated with dark crust, 6 to 8 minutes, adjusting heat as necessary. (Scrape any fond that collects on spoon back into onions.)
• Stir in 1/4 cup water, scraping pot bottom to loosen crust, and cook until water evaporates and pot bottom has formed another dark crust, 6 to 8 minutes.
• Repeat process of deglazing 2 or 3 more times, until onions are very dark brown.
• Stir in wine and balsamic vinegar, stirring frequently, until wine evaporates, about 5 minutes.
• Stir in broths, 2 cups water, the thyme, bay leaf and parsley (tied with twine or wrapped in cheese cloth for easy removal from pot) and 1/2 teaspoon salt, scraping up any final bits of browned crust on bottom and sides of pot.
• Increase heat to high and bring to simmer.
• Reduce heat to low, cover, and simmer 30 minutes. Remove and discard herbs, then season with salt and pepper to taste.
• For the croutons: While soup simmers, arrange baguette slices in single layer on baking sheet and bake in 400-degree oven until bread is dry, crisp, and golden at edges, about 10 minutes. Set aside.
• To serve: Adjust oven rack 4 to 6 inches from broiler and heat broiler.
• Set heat-safe soup bowls or crocks on rimmed baking sheet and fill each with about 1 1/2 cups soup.
• Top each bowl with two toasted baguette slices (try not to overlap) and divide Swiss cheese slices, laying them in a single layer, if possible, on bread.
• Sprinkle each serving with about 2 tablespoons grated Asiago cheese and broil until well browned and bubbly, 7 to 10 minutes.
• If using regular soup bowls, broil the toasts and the cheese only and then place the toasts on top of the soup.
• Cool 5 minutes and serve.
