Ingredients

To craft this classic dish, you'll need the following ingredients:

For the Soup:

• 6 large yellow onions, thinly sliced
• 4 tablespoons unsalted butter
• 2 tablespoons olive oil
• 1 teaspoon salt
• 1 teaspoon sugar
• 4 cups beef broth (or a mix of beef and chicken broth for lighter flavor)
• 2 cups water (optional, for a thinner consistency)
• 1/2 cup dry white wine (such as Sauvignon Blanc)
• 1 tablespoon all-purpose flour
• 1 bay leaf
• 3-4 sprigs of fresh thyme (or 1/2 teaspoon dried thyme)
• Salt and black pepper, to taste

For the Topping:

• 1 baguette, sliced into rounds
• 2 cups grated Gruyère cheese
• Optional: Parmesan or Swiss cheese for added flavor

Instructions

French Onion Soup relies on patience and technique to produce its signature depth of flavor. Follow these steps to create the perfect bowl:

1. Caramelize the Onions

• Melt the butter with the olive oil in a large, heavy-bottomed pot over medium heat. Add the sliced onions and sprinkle on the salt. Cook, stirring occasionally, until the onions become soft and translucent (about 10 minutes).
• Stir in the sugar to help the onions caramelize. Reduce the heat to medium-low and cook for 30-40 minutes, stirring often. The onions should turn a deep golden-brown color. Be patient here; this step is key to the soup's flavor.

2. Build the Broth

• Sprinkle the flour over the caramelized onions and stir to coat. Cook for 1-2 minutes to remove the raw flour taste.
• Deglaze the pot with white wine, scraping up any browned bits from the bottom. Allow the wine to simmer and reduce slightly (about 2-3 minutes).
• Add the beef broth, water (if using), bay leaf, and thyme sprigs. Bring the soup to a boil, then reduce the heat to low and simmer uncovered for 20-30 minutes. Taste and adjust the seasoning with salt and black pepper. Remove the bay leaf and thyme sprigs before serving.

3. Prepare the Topping

• Preheat your oven's broiler. Place the baguette slices on a baking sheet and toast under the broiler until golden, flipping once.
• Once toasted, rub the bread lightly with a cut clove of garlic for added flavor (optional).

4. Assemble and Serve

• Ladle the soup into oven-safe bowls. Place 1-2 baguette slices on top of each bowl, then cover generously with Gruyère cheese.
• Place the bowls on a baking sheet and broil until the cheese is melted, bubbly, and golden brown. Keep a close eye to avoid burning.
• Carefully remove the bowls from the oven (they’ll be hot!), and serve immediately.

Tips for Perfect French Onion Soup

• Choose the right onions: Yellow onions are ideal for their natural sweetness, but you can mix in red or sweet onions for variation.
• Cook patiently: The longer you caramelize the onions, the richer the flavor. Rushing this step will result in a less complex soup.
• Don’t skip the cheese: Gruyère is the traditional choice for its meltability and nutty flavor, but other cheeses like Comté or Swiss also work well.
• For a vegetarian version: Substitute the beef broth with vegetable stock and add a splash of mushroom stock or soy sauce for depth.

Serving Suggestions & Variations

French Onion Soup is best enjoyed fresh from the oven, paired with a glass of dry white wine or even a light red like Pinot Noir. Serve it alongside a crisp green salad for a complete meal. For a twist, experiment with these variations:

• Add herbs: A sprinkle of fresh parsley or chives on top can brighten the dish.
• Make it heartier: Stir in shredded beef or roasted mushrooms for a more substantial bowl.
• Try different breads: Substitute the baguette with sourdough or a hearty rye for a unique touch.

There you have it, the perfect recipe for crafting a comforting and timeless French Onion Soup at home. With its deep flavors and inviting aroma, this dish will quickly become a favorite in your household. Grab a spoon and savor every bite!
