2. Ingredients Needed for This Delicious French Onion Soup Recipe
- 4 large yellow onions, thinly sliced
- 3 tablespoons unsalted butter
- 2 tablespoons olive oil
- 4 cups beef broth (or vegetable broth for vegetarian option)
- 1 cup dry white wine (optional but recommended)
- 2 teaspoons sugar (for caramelizing onions)
- 1 teaspoon fresh thyme leaves
- Salt and freshly ground black pepper, to taste
- French baguette, sliced and toasted
- 2 cups grated Gruyère cheese (or Swiss cheese)
3. Step-by-Step Instructions for Perfectly Caramelized Onions and Soup
Preparing the Caramelized Onions
Start by thinly slicing your yellow onions. In a large skillet, melt the butter with the olive oil over medium heat. Add the onions and cook, stirring frequently, until they become soft and translucent. Sprinkle the sugar over the onions and continue cooking, stirring often. Allow the onions to caramelize, turning a deep golden-brown hue, which should take around 30-40 minutes. This slow caramelization is key to developing rich, sweet flavor essential for a comforting French onion soup.
Building the Soup
Once your onions are perfectly caramelized, pour in the white wine (if using) to deglaze the pan, scraping up any browned bits. Let the wine reduce by half for about 5 minutes. Add the beef broth, thyme, salt, and pepper. Bring the mixture to a gentle simmer and cook for an additional 15-20 minutes to allow flavors to meld beautifully.
Preparing the Baguette Croutons and Melty Cheese
While your soup simmers, preheat your oven or broiler. Slice the baguette into rounds or strips, then toast them until crispy. Ladle the hot soup into oven-safe bowls, top each with the toasted bread slices, and sprinkle generously with grated Gruyère cheese.
Broiling for the Perfect Finish
Place the bowls under the broiler until the cheese melts and turns bubbly and golden brown. Carefully remove from the oven and serve immediately, enjoying the gooey cheese combined with richly flavored caramelized onions in every spoonful.
4. Storage Tips for Your French Onion Soup
If you have leftovers, store the cooled soup in airtight containers in the refrigerator for up to 2 days. To reheat, warm gently on the stove over low heat, and add fresh toasted bread and cheese if you’d like to recreate the original broiled presentation.
5. Serving Suggestions to Enhance Your Autumn Feast
