Step‑by‑Step Instructions for Easy French Onion Soup
Step 1: Caramelize the Onions
Begin by heating a large skillet over medium heat and adding 2 tablespoons of butter and 1 tablespoon of olive oil. Once the butter has melted, add 4 thinly sliced yellow onions, along with 2 sprigs of fresh thyme and 1 bay leaf. Cook the onions on low, stirring every 10 minutes, for about 45 minutes, until they reach a deep golden brown and caramelized texture. Season lightly with salt to enhance their sweetness.
Step 2: Deglaze and Simmer
Once the onions are beautifully caramelized, remove the bay leaf and pour in ½ cup of white wine to deglaze the skillet, scraping up any flavorful bits from the bottom. Allow the wine to cook off for about 2-3 minutes, then add 4 cups of beef broth. Increase the heat to bring the mixture to a gentle boil, then reduce to low and let it simmer uncovered for another 15 minutes to meld the flavors of your Easy French Onion Soup.
Step 3: Prepare for Broiling
While the soup simmers, preheat your broiler. Take 4 oven-safe bowls and ladle the soup into them, filling each about three-quarters full. Place a toasted baguette slice atop each bowl of soup, making sure it sits securely. Divide approximately 1 cup of grated Gruyère cheese evenly among the bowls, sprinkling it generously over the bread for that perfect cheesy topping, ready to melt.
Step 4: Broil the Soup
Place the filled bowls under the broiler set to high for about 3-5 minutes. Keep a close eye on them as the cheese melts and begins to bubble and brown—a beautiful sight! When the cheese is golden and melted to your liking, carefully remove the bowls from the oven, as they will be extremely hot.
Step 5: Garnish and Serve
For an extra touch of flavor, garnish your Easy French Onion Soup with a sprinkle of fresh thyme leaves. Serve immediately, allowing the comforting aroma of the caramelized onions and melted cheese to envelop your kitchen and entice your guests to dig in. Enjoy the heartwarming delight of this classic French dish!
