French onion soup

Ingredients

• 2 lbs Onion -- substitute: Shallot
• 3 tbsp Butter
• 2 cloves Garlic
• 1/2 cup White Wine -- substitute: Lemon
• 6 cups Beef Broth -- substitute: Water
• 1 Bay Leaf
• 1 tsp Fresh Thyme -- substitute: Rosemary, Sage
• 1/4 tsp Black Pepper
• 1/2 tsp Salt
• 1 baguette Sourdough Bread
• 2.5 cups Gruyère Cheese

Steps

1. Slice 2 lbs of onions into thin half-moons, about 1/4 inch thick.

   10 min

2. Melt 3 tablespoons of butter in a large heavy-bottomed pot or Dutch oven over medium heat. Add the sliced onions and stir to coat evenly.

   3 min — onions are glistening and starting to soften

3. Continue cooking the onions, stirring occasionally, until they are deeply caramelized and golden brown. This is the critical step—do not rush it.

   45 min — onions are a rich amber color, sweet-smelling, and have reduced significantly in volume

4. Add 2 minced garlic cloves and stir constantly until fragrant, about 1 minute.

   1 min — fragrant and the raw garlic smell is gone

5. Pour in 1/2 cup of dry white wine or dry sherry, scraping the bottom of the pot to release any browned bits. Simmer until the liquid is mostly reduced, about 3 minutes.

   3 min — wine is nearly evaporated and the pot smells rich and concentrated

6. Add 6 cups of beef broth, 1 bay leaf, 1 teaspoon of fresh thyme leaves (or 1/2 teaspoon dried thyme), and 1/4 teaspoon of black pepper. Bring to a simmer.

   5 min — broth reaches a gentle simmer with small bubbles breaking the surface

7. Simmer the soup uncovered for 20 minutes to allow the flavors to meld. Taste and adjust seasoning with salt and additional black pepper as needed.

   20 min — flavors are well-integrated and the soup tastes rich and savory

8. While the soup simmers, preheat your oven to 400°F. Slice a baguette into 1/2-inch-thick slices and arrange them on a baking sheet. Toast in the oven for 3 to 4 minutes until golden and crisp.

   5 min

9. Ladle the hot soup into oven-safe bowls. Top each bowl with 1 to 2 toasted baguette slices, then sprinkle 1/2 cup of shredded Gruyère cheese (or a mix of Gruyère and Emmental) over the bread.

   3 min

10. Place the filled bowls on a baking sheet and broil for 2 to 3 minutes, watching carefully, until the cheese is melted, bubbly, and lightly browned on top.

    3 min — cheese is melted, bubbling at the edges, and golden brown

Plating ideas

• Serve each bowl with a generous layer of melted, bubbling cheese draped over the toasted bread, so the cheese stretches as you dip your spoon into the soup. — The contrast of crispy bread, molten cheese, and silky soup is essential to the dish's appeal.
• Garnish with a small sprig of fresh thyme placed on top of the cheese before broiling for a touch of color and aroma. — This adds visual refinement and a hint of herbal fragrance as the diner lifts the bowl to their lips.
• Serve in rustic ceramic or stoneware bowls that can go directly from oven to table, emphasizing the homestyle, warming nature of the dish. — The bowls retain heat and add to the tactile, comforting experience of eating the soup.
