Step-by-Step Instructions

Now that we have our ingredients, let’s get cooking!

Step 1: Prepare the Onions

Start by peeling your onions. I always feel a little dramatic chopping onions. It’s like I’m preparing for a culinary battle! Slice the onions thinly. Aim for about 1/8 inch thick. The uniformity helps with even cooking. Toss them into a large pot and add that chopped raw onion. This mix intensifies the sweetness when cooked.

Step 2: Sauté with Care

In a large pot or Dutch oven, heat the oil and butter over medium heat. You want them to melt together, bubbling slightly. Add your sliced onions and give them a gentle stir. Sprinkle in the sugar and salt. The sugar will help with caramelization, while the salt draws out moisture.

Step 3: Caramelize the Onions

Now here comes the waiting game. Cook the onions, stirring occasionally, for about 30 to 40 minutes. This is where patience pays off. You want them to turn a lovely golden-brown, rich color. Lower the heat if they start to get too dark too soon.

Step 4: Add Flour

Once the onions are perfectly caramelized, sprinkle the flour over the top. Stir well to combine. This will thicken your broth later. Cook for another 2 to 3 minutes. You want the raw flour taste to disappear.

Step 5: Deglaze with Wine

Pour in the white wine, scraping the bottom of the pot to release any browned bits. These bits are flavor bombs! Bring to a boil and let it simmer until most of the wine evaporates. This will take about 5 minutes.

Step 6: Add Broth

Next, slowly pour in the beef stock. Stir it all together, bringing it back to a gentle boil. Reduce the heat to low, and let it simmer for about 15 minutes. Taste and adjust seasoning with pepper and salt as necessary.

Step 7: Embrace Cognac

Stir in the cognac. Oh, the depth added here is worth every ounce. Simmer for another five minutes. Optional balsamic vinegar could also be added here for a slight sweetness.

Step 8: Prepare the Bread

While your soup is simmering, get the bread ready. Preheat your broiler. Place the bread slices on a baking sheet, drizzle with olive oil, and toast until golden on both sides. Flip them midway for an even toast.

Step 9: Assemble

Ladle the hot soup into oven-safe bowls. Top generously with toasted bread and sprinkle a mix of Swiss and Parmesan cheeses over each bowl.

Step 10: Broil Until Bubbly

Place the bowls on a baking sheet so they’re easier to handle. Broil them in the oven for about 3 to 5 minutes until the cheese melts and is bubbly. Keep a close eye on them, though—they can go from perfect to burnt in a flash!

Tips & Tricks

As with any favorite recipe, there are a few tricks up your sleeve. Here are some handy tips to ensure your French onion soup peaks in flavor:

  • Use Quality Stock: Homemade beef stock makes a significant difference. If using store-bought, choose a high-quality option for authentic flavor.
  • Patience is Key: Don’t rush the caramelization process. High heat can burn the sugars and ruin that deep flavor.
  • Experiment with Cheeses: While Swiss cheese is traditional, feel free to mix in Gruyère or even a hint of sharp cheddar for an added kick.
  • Herbs for Flavor: Thyme works beautifully here. Fresh or dried can enhance that comforting depth of flavor.
  • Toast Ahead: You can toast your bread ahead of time, but keep the soup warm until serving to maintain texture.

Can I Store Julia Child’s French Onion Soup?

Absolutely! This soup stores well. You can keep it in the refrigerator for about 3 to 4 days. Just let it cool completely before transferring it to an airtight container. Reheat on the stovetop gently before serving, adding a little water or extra beef stock if necessary.

For longer storage, you can freeze the soup. However, remember to omit the bread and cheese if you’re planning on freezing it. Those elements are best added fresh right before serving.

What Can I Serve with Julia Child’s French Onion Soup?

French onion soup can star on its own, yet it’s wonderful to complement it with some sides. Here are some ideas:

  • Simple Green Salad: A light salad can cut through the richness of the soup.
  • Garlic Bread: Because you can never have enough bread, right?
  • Grilled Cheese Sandwich: The classic pairing of soup and sandwich makes the meal even more comforting.
  • Charcuterie Board: Perfect for a gathering. A board with cheeses, meats, and olives provides a fun, shareable option.
  • Roasted Vegetables: A side of seasonal veggies brightens up the meal.

Variations

French onion soup is flexible. Here are five variations to consider for your next batch:

  • French Onion Soup with Mushrooms: Adding sautéed mushrooms enhances that earthy flavor profile. Simply toss in about 1-2 cups of sliced mushrooms when you start caramelizing the onions.
  • Vegetarian Version: Swap the beef stock for vegetable stock to make a lighter, plant-based version. Add more herbs to enrich that flavor!
  • French Onion Soup with Cheese Crust: Instead of toasting bread, consider a cheesy soufflé topping. Whip some egg whites and fold in cheese for a decadent and rich twist.
  • Spicy French Onion Soup: Introduce a pinch of red pepper flakes or a splash of hot sauce to give it a fiery kick.
  • Cognac-Free French Onion Soup: If you want to avoid alcohol, simply substitute cognac with additional beef stock or a splash of apple cider vinegar.
