Ingredients

• For the soup:
• Four tablespoons of unsalted butter
• One tablespoon of vegetable oil
• Three pounds of Vidalia onions (approximately five medium), halved lengthwise and thinly sliced
• Three-quarters teaspoon of salt
• Half teaspoon of freshly ground black pepper
• Three-quarters teaspoon of granulated sugar
• One cup of dry white wine
• Two tablespoons of all-purpose flour
• Six cups of beef broth
• One teaspoon of Worcestershire sauce
• Half teaspoon of dried thyme
• Two bay leaves
• For the toppings:
• One small baguette, sliced into half-inch pieces
• One tablespoon of dry sherry
• Eight ounces of Gruyère cheese, grated (approximately two heaping cups)
• Half cup of grated Parmigiano Reggiano cheese
• Possible Substitutions:
• If Vidalia onions are unavailable, you can use sweet onions such as Walla Walla or even yellow onions for a slightly different flavor profile. Feel free to substitute the Gruyère cheese with Swiss cheese if you prefer a milder taste, and if you don't have fresh thyme on hand, dried thyme works just as well. To elevate the dish with a twist, consider adding a splash of brandy along with the sherry for extra depth.

Preparation Method

Start by preparing your ingredients. The key to a stunning French onion soup lies in the proper caramelization of the onions. In a large Dutch oven or a heavy-bottomed soup pot, melt the unsalted butter over medium heat. Once the butter begins to foam, carefully add the vegetable oil. These fats not only provide flavor but also help in browning the onions evenly.

Next, introduce the sliced onions to the pot, along with the salt, black pepper, and granulated sugar. The sugar may seem unusual, but it helps to accelerate the caramelization process, bringing out the natural sweetness of the onions. Cook the mixture uncovered, stirring occasionally. As you engage in this stirring, take notice of how the pale, raw onions begin to soften and gradually shift from a translucent state to a golden hue. This process will take about 45 to 55 minutes—don't rush it! Stir more frequently as the onions begin to brown, ensuring you scrape up any ‘fond’—those delicious brown bits clinging to the bottom of your pot.

If at any point you notice the onions starting to stick or burn, reduce the heat slightly or add a splash of water to help them along. The goal is to achieve a richly caramelized, jam-like consistency before moving to the next step. The kitchen will fill with a glorious aroma, a prelude to the delightful flavors that are about to unfold.

Once the onions are golden brown and fragrant, pour in the cup of dry white wine, cranking the heat up to high. As the wine bubbles away, continue to stir and relish in the magic taking place. You want to cook off most of the alcohol, allowing the wine to reduce significantly, which will take about 8 to 10 minutes. Look for a syrupy consistency that clings to the onions.

Now it’s time to thicken our soup base. Sprinkle the flour over the onion mixture and cook for a minute while continuing to stir. This step will ensure a velvety texture for your soup. Gradually, pour in the six cups of beef broth, stirring until fully combined with the onion mixture. Add the Worcestershire sauce, dried thyme, and bay leaves at this point.

Raise the heat to high until the mixture reaches a rolling boil, then reduce the heat to a gentle simmer. Cover the pot and allow it to simmer for about 30 minutes. The flavors will meld beautifully, so don’t skip this crucial step. Take a moment to relax and maybe even prepare your toppings during this time.

While the soup is simmering, preheat your oven to 400°F (204°C). Slice the baguette into half-inch pieces and arrange them in a single layer on a baking sheet. Bake in the preheated oven for around 10 minutes, until the baguette slices are crispy and golden at the edges. This crouton-style preparation will add essential texture to your soup.

After 30 minutes have passed, carefully remove the bay leaves from the soup. Add in the tablespoon of dry sherry for an extra layer of flavor, and adjust the seasoning as needed. Don’t hesitate to enhance the soup further with a splash of Worcestershire sauce or a teaspoon more of sugar if you desire a subtly sweeter note.

Now we are ready to build our delectable French onion soup. Position an oven rack six inches away from the broiler, and preheat the broiler. If you have broiler-safe crock dishes, place them on a baking sheet. Ladle in the hot soup, filling each crock generously. Top with one or two crispy baguette slices, ensuring they nestle comfortably within the soup.

Next, it’s time for the pièce de résistance—grate your Gruyère and Parmigiano Reggiano cheeses atop the toasted bread, allowing their luxuriant flavors to mingle with the warm soup below. Slide the baking sheet into the broiler and watch as the cheese melts and bubbles, a glorious sight to behold that takes only about 3 to 5 minutes. Keep a close eye on it to prevent burning; you want that beautiful golden-brown coloration without any char.

If you opt for traditional soup bowls instead of crocks, simply place your cheese-topped baguette slices under the broiler for about 2 minutes until melted, then transfer them to your soup bowls and ladle the flavorful broth around them.

Allow the soup to cool slightly before diving in, as it will be blisteringly hot. The anticipation will only intensify your enjoyment, but trust us—it will be worth the wait!

Tips and Conclusion

If you are looking to elevate the experience, consider serving the French onion soup with a refreshing side salad, perhaps one dressed in a light vinaigrette to balance the richness of the soup. Alternatively, try pairing it with a robust red wine, such as a full-bodied Cabernet Sauvignon or a comforting Pinot Noir, which will complement the rich flavors beautifully.

For those who love meal prepping, this soup freezes exceptionally well. Store it without the bread or cheese to keep the texture intact, and savor it up to three months later. When you are ready to enjoy it, simply reheat, prepare fresh toasts, and top with cheese, bringing back that home-cooked warmth.
Preparing French onion soup is a labor of love, one that rewards your patience with rich, layered flavors and a delightful experience. The rich aroma wafting through your kitchen as the onions caramelize is just a teaser for the comforting bowl of soup that awaits. There’s something incredibly rewarding in crafting this dish from scratch, especially when you serve it to family and friends.
