  Salt Enhances flavor; adjust to taste.
  Water Used to deglaze the pot while cooking onions. Can use low-sodium broth to avoid excessive salt.
  All-Purpose Flour Thickens the soup base. A gluten-free flour blend can be used as a substitute.

  Beef Stock Forms the rich base. Use vegetable stock for a vegetarian version.
  Low-Sodium Chicken Broth Balances with beef stock; can be substituted with additional beef stock.
  Thyme Enhances flavor with herbal notes. Fresh or dried can be used interchangeably.
  Bay Leaves Adds aromatic complexity; always remove before serving.

• For the Topping
  Baguette Base for the cheese toast, providing crunch; other crusty bread can be used.
  Garlic Infuses flavor into the bread; can be omitted if desired.
  Gruyere Cheese (or Swiss) Melts beautifully atop the soup, imparting flavor; use any melting cheese as a substitute.
  Parmesan Cheese Adds saltiness and depth; can replace with Pecorino Romano.

How to Make French Onion Soup

1. Melt Butter: In a 6-quart heavy pot, melt the unsalted butter over medium heat until it starts to foam, releasing its rich aroma and warming your cooking space.

2. Sauté Onions: Add the sliced yellow onions along with salt to the pot. Sauté for 4550 minutes, stirring frequently until they achieve a deep caramel color.

• First 15 minutes: Stir every 34 minutes.
• Next 30 minutes: Stir more often (every 12 minutes) to prevent burning.
• Use a splash of water to deglaze if necessary.

1. Sprinkle Flour: Once the onions are beautifully caramelized, sprinkle in the all-purpose flour. Sauté for 1 minute, allowing it to absorb those wonderful flavors.

2. Add Wine: Pour in the dry white wine while scraping the bottom of the pot to release the flavorful browned bits, incorporating them into your soup s base.

3. Combine Broths: Add the beef stock, low-sodium chicken broth, thyme, and bay leaves to the pot. Allow the mixture to come to a gentle simmer, filling your kitchen with mouthwatering scents.

4. Simmer: Reduce the heat to low, cover the pot, and let it simmer for 1520 minutes. This lets all those delicious flavors meld together beautifully.

5. Prepare Baguette: Preheat your oven to 450°F. Prepare your baguette slices by rubbing them with garlic and toasting them until they’re golden and crunchy.

6. Ladle Soup: Carefully remove the bay leaves and thyme from the soup. Ladle the warm soup into broiler-proof bowls, topping each with a generous amount of toasted baguette slices and an abundance of cheese.

7. Broil: Place the cheese-topped bowls under the broiler for about 25 minutes, until the cheese is melting and bubbly with a gorgeous golden brown sheen.

8. Serve: Serve the French Onion Soup immediately, garnished with fresh parsley if desired, and enjoy the comforting warmth with every spoonful!

Optional: Pair with a light salad for a delightful contrast.
