Classic French Onion Soup
The secret to a truly “premium” version is the patience required to caramelize the onions until they are a deep, jammy brown, providing a rich sweetness to the savory beef broth.
⏱️ Recipe Details
- Yields: 4 servings
- Prep time: 15 minutes
- Cook time: 1 hour (mostly for the onions)
- Difficulty: Medium
🛒 The Ingredients
The Soup Base:
- 5-6 Large Yellow Onions, thinly sliced
- 4 cups Beef Broth, high quality or homemade
- 2 tbsp Butter and 1 tbsp Olive Oil
- 1/2 cup Dry White Wine (to deglaze the pan)
- Fresh Thyme and 1 Bay Leaf
The Topping:
- 1 Baguette, sliced and toasted into crostini
- 2 cups Gruyère Cheese, shredded (or Provolone for a milder melt)
👩🍳 Step-by-Step Instructions
1. Caramelize the Onions
In a heavy pot, melt the butter and oil over medium-low heat. Add the onions and cook slowly, stirring occasionally. This takes about 45 minutes until they are dark mahogany and sweet.
2. Deglaze and Simmer
Turn up the heat slightly and add the wine, scraping the bottom of the pot to release the flavorful brown bits. Add the beef broth, thyme, and bay leaf. Let it simmer for 15–20 minutes.
3. Toast the Bread
While the soup simmers, toast your baguette slices in the oven until they are dry and golden. This prevents them from becoming too soggy in the broth.
4. The Broiler Finish
Ladle the soup into oven-safe crocks. Place one or two toasted bread slices on top and cover generously with the shredded cheese. Place under the broiler for 2–3 minutes until the cheese is melted, browned, and bubbling over the edges.
