Make-Ahead Instructions

I love having this Benihana Onion Soup ready whenever I crave its rich flavors. Here’s how you can prepare parts of the soup ahead of time to make your cooking experience seamless:

  1. Caramelize the Onions Early
  • Start by caramelizing the onions until they turn a deep golden brown. Let them cool completely, then store them in an airtight container in the refrigerator for up to three days.
  1. Prepare the Broth in Advance
  • Follow the recipe to make the beef broth mixture. Once it’s ready, allow it to cool and transfer it to a separate airtight container. Keep it refrigerated for up to two days.
  1. Combine Onions and Broth
  • When you’re ready to serve, combine the pre-caramelized onions with the prepared broth in a large soup pot. Heat the mixture over medium heat, stirring occasionally to blend the flavors.
  1. Grate the Gruyère Cheese Ahead of Time
  • For convenience, grate your Gruyère cheese in advance and store it in a sealed container in the fridge. This saves time during the final assembly.
  1. Final Assembly and Broiling
  • Reheat the soup until it’s simmering. Ladle it into oven-safe bowls, sprinkle a generous amount of grated Gruyère on top, and place the bowls under the broiler. Broil until the cheese is melted and bubbly, achieving that perfect Benihana finish.

Directions

Recreating Benihana’s iconic onion soup at home is simpler than you might think. Follow these steps to achieve that rich, flavorful taste.

Prep

  1. Slice the Onions: Peel and thinly slice 4 large yellow onions using a sharp chef’s knife. Aim for uniform slices to ensure even caramelization.
  2. Prepare Ingredients: Mince 3 cloves of garlic and measure out 2 tablespoons of all-purpose flour. Grate 1 cup of Gruyère cheese and set aside.
  3. Measure Liquids: Pour 4 cups of beef broth and 1/2 cup of dry white wine. Measure 1 tablespoon of Worcestershire sauce.
  4. Gather Herbs and Seasonings: Strip fresh thyme leaves from 2 sprigs and set aside. Have salt and pepper ready for seasoning.

Cook

  1. Caramelize the Onions: In a large soup pot or Dutch oven, melt 4 tablespoons of unsalted butter with 2 tablespoons of olive oil over medium heat. Add the sliced onions and stir to coat them in the fat. Cook, stirring frequently, for about 25-30 minutes until the onions are deeply browned and caramelized. Sprinkle 1 teaspoon of sugar over the onions halfway through to enhance sweetness.
  2. Add Garlic and Flour: Stir in the minced garlic and cook for an additional 2 minutes until fragrant. Sprinkle the 2 tablespoons of all-purpose flour over the onions and garlic, stirring constantly to form a roux. Cook for 1-2 minutes to eliminate the raw flour taste.
  3. Incorporate Liquids: Gradually pour in the 4 cups of beef broth and 1/2 cup of dry white wine, stirring continuously to prevent lumps. Add 1 tablespoon of Worcestershire sauce and the fresh thyme sprigs.
  4. Simmer the Soup: Bring the mixture to a gentle boil, then reduce the heat and let it simmer uncovered for 20-25 minutes. The soup will thicken and the flavors will meld together. Season with salt and pepper to taste, removing the bay leaf before proceeding.

Assemble

  1. Prepare Oven-Safe Bowls: Preheat your broiler. Ladle the hot soup into oven-safe soup bowls, leaving a little space at the top for the cheese.
  2. Add Gruyère Cheese: Sprinkle a generous amount of grated Gruyère cheese over each bowl of soup, covering the surface evenly.
  3. Broil to Perfection: Place the bowls on a baking sheet and position them under the broiler. Broil for 2-3 minutes or until the cheese is melted, bubbly, and lightly golden brown. Keep a close eye to prevent burning.
  4. Serve Immediately: Carefully remove the bowls from the oven using oven mitts. Let them cool slightly before serving to enjoy the perfect balance of savory soup and rich, melted cheese.
