How to Make Julia Child’s French Onion Soup

Let’s get into the kitchen! This recipe involves a bit of patience but trust me, it’s worth it.

Step 1: Prepare the Onions

First, slice those onions thinly. We want them to caramelize and become sweet and soft. In a large pot or Dutch oven, heat the vegetable oil and butter over medium heat. Add the onions, along with the brown sugar and salt. 

Stir occasionally, letting them soften. This process takes about 30-40 minutes. Yes, it’s a commitment, but as those onions caramelize, they will develop a heavenly sweetness.

Step 2: Flour and Broth

Once the onions are a beautiful golden hue, sprinkle the flour over them. Stir to coat the onions evenly. Cook for a couple of minutes to remove any raw flour taste. 

Then, slowly pour in the beef broth and white wine while continuously stirring. Bring this mixture to a gentle simmer. Let it bubble away for 30 minutes, stirring occasionally, to integrate those deep flavors.

Step 3: The Cognac Twist

Now’s the fun part! Add the cognac or brandy; it provides warmth and richness to the soup. Season with black pepper to taste. You can add a touch more salt if necessary, depending on your broth. If you like, toss in the thyme leaves for an herby kick.

Step 4: Prepare the Bread and Cheese

While the soup simmers, toast those baguette slices. A quick brush of olive oil on each side will give them a perfect crunch. Once golden, take them out and set them aside. Next, it’s time for the cheese. Combine the Gruyère and Parmesan in a bowl, mixing well.

Step 5: Assemble the Soup

Preheat your oven’s broiler. Ladle the soup into oven-safe bowls, leaving some room for the bread and cheese. Place one or two toasted baguette slices on top of the soup. Don’t be shy—cover it generously with the cheese mixture. 

For that gooey, golden goodness, place the bowls under the broiler. Keep a close eye (you know how sneaky broilers can be) until the cheese is bubbling and slightly browned.

Step 6: Serve and Enjoy

Carefully remove the bowls from the oven. Drizzle a touch of extra virgin olive oil on top for a fragrant finish. Enjoy the warmth, depth, and transformative flavors of this classic dish.

Recipe Notes

  1. Onions: Use yellow onions for the best caramelization. They sweeten and soften beautifully over time.
  2. Broth: Opt for a high-quality beef broth. Homemade is wonderful but store-bought can work just fine too.
  3. Wine: White wine is a must for acidity. Choose one that you enjoy drinking.
  4. Cheese: Go for freshly grated cheese whenever possible—it melts more smoothly and has better flavor.
  5. Cognac/Brandy: Feel free to skip it if you prefer a family-friendly version or substitute with apple cider.
  6. Soup Consistency: If you like a thicker soup, feel free to add a little more flour or reduce the liquid slightly.

Recipe Variations

If you’re feeling adventurous, here are some ideas to switch things up:

  • Vegetarian Variation: Replace beef broth with vegetable stock and ensure the cheese is vegetarian-friendly.
  • Mushroom Add-In: For earthy depth, toss in some sautéed mushrooms when caramelizing the onions.
  • Herb Variations: Besides thyme, rosemary or even a dash of sage can add unique flavors.
  • Spice It Up: Consider adding a sprinkle of red pepper flakes or a dash of cayenne for a bit of heat.
  • Cheese Twist: Mix in other cheeses such as Fontina or Havarti for a different flavor profile.
  • Baked Surprise: Add some garlicky spinach or leeks under the cheese for a surprise layer of flavor.
