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.

FRENCH ONION SOUP

Steps:

• Peel and cut the onions into slices to measure 4 cups. In a 4-quart nonstick Dutch oven, melt the butter over medium-high heat. Stir in onions to coat with butter. Cook uncovered 10 minutes, stirring every 3 to 4 minutes.
• Reduce heat to medium-low. Cook uncovered 35 to 40 minutes longer, stirring well every 5 minutes, until onions are deep golden brown (onions will shrink during cooking).
• Stir in broth, water, pepper, thyme and bay leaf. Heat to boiling over high heat. Once mixture is boiling, reduce heat just enough so mixture bubbles gently. Cover with lid; simmer 15 minutes. Meanwhile, shred the Gruyère cheese by rubbing it across the largest holes of a grater to measure 1 cup; set aside.
• You may need to move the oven rack so it is near the broiler. Set the oven control to broil. On a cookie sheet, place the bread slices. Broil with tops about 5 inches from heat 1 to 2 minutes or until golden brown. Turn bread over; broil 1 to 2 minutes longer until golden brown. Place toasted bread in 4 ovenproof bowls or individual ceramic casseroles (do not use glass, which cannot withstand heat of broiler and may break).
• Remove bay leaf from soup. Ladle soup into bowls. Top with Gruyère cheese. Sprinkle with Parmesan cheese. Place bowls in pan with shallow sides.
• Broil soup bowls with tops about 5 inches from heat 1 to 2 minutes or just until cheese is melted and golden brown. Watch carefully so cheese does not burn. Serve with additional French bread if desired.

OUR FAVORITE FRENCH ONION SOUP

Steps:

• In a large Dutch oven or other large pot, melt 3 tablespoons butter over medium heat. Add the oil and onions; cook onions are until softened, stirring occasionally, about 15 minutes. Add the salt, pepper, and sugar; continue to cook, stirring occasionally, until onions are deep golden brown and caramelized, reducing heat slightly if onions seem to be browning too quickly, 35 to 45 minutes more.
• Add wine and raise heat to high. Cook until almost all liquid has evaporated, 8 to 10 minutes.
• Tie thyme and bay leaves into a bundle with twine. Add broth and herb bundle to pot with onions. Bring to a boil, reduce to a simmer, and cook, uncovered, until broth is thickened and flavorful, 20 to 30 minutes. Remove from heat and whisk in remaining 2 tablespoons butter. Taste and adjust seasoning.
• Heat the broiler. Cut two 1/2-inch baguette slices for every serving of soup. Place baguette slices on a rimmed baking sheet and toast in oven until crisp and dry but not browned, about 1 minute per side. Rub one side of each toast with the garlic clove and set aside.
• Place ramekins or ovensafe bowls on a rimmed baking sheet, add 1/2 teaspoon of sherry to the bottom of each, and ladle soup on top. Top each serving of soup with two garlic-rubbed toasts. Divide cheese among the servings, covering the bread and some of the soup. Carefully transfer baking sheet to oven and broil until cheese is melted and bubbling, 4 to 8 minutes. (Alternatively, if using regular soup bowls: Top each garlic-rubbed toast with some cheese and return to broiler to melt, about 2 minutes more. Divide sherry and soup among bowls, sprinkle with remaining cheese, and top each serving with two cheese toasts.)

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.
