Step‑by‑Step Instructions for Easy French Onion Soup
Step 1: Caramelize the Onions
In a large skillet, heat 2 tablespoons of butter and 1 tablespoon of olive oil over medium heat. Add 3 large sliced onions, along with 2 sprigs of fresh thyme and 1 bay leaf. Sauté gently on low heat for about 45 minutes, stirring every 10 minutes, until the onions are a deep golden brown and have caramelized beautifully. Sprinkle with salt for flavor enhancement during the process.
Step 2: Deglaze and Simmer
Once your onions are perfectly caramelized, pour in 1/2 cup of white wine and increase the heat to high to bring it to a gentle boil. Allow the alcohol to cook off for about 2-3 minutes, scraping the browned bits from the bottom of the skillet for added flavor. Then, add 6 cups of beef broth (or vegetable broth for a vegetarian option) and let the mixture simmer on low for 20-30 minutes, allowing the flavors to meld beautifully.
Step 3: Prepare for Broiling
While your soup is simmering, preheat your broiler to high. Grab 4 oven-safe bowls and ladle the hot soup into each one, ensuring an equal amount of the rich onion mixture fills them. Top each bowl with a slice of toasted baguette, then generously sprinkle with grated Gruyère cheese to create that luscious, melty topping we all love.
Step 4: Broil the Soup
Carefully place the bowls under the broiler for 3-5 minutes. Watch closely as the cheese melts, bubbles, and turns golden brown—this step is key for creating the perfect finish to your Easy French Onion Soup. Ensure to rotate the bowls if necessary for even browning.
Step 5: Garnish and Serve
After broiling, remove the bowls from the oven (handle with care as they will be hot!). If desired, add a few fresh thyme leaves on top for an aromatic touch. Serve immediately alongside a crisp green salad or some homemade bread for a dipping delight that complements the rich flavors of this classic French Onion Soup.
