Step‑by‑Step Instructions for Irresistible French Onion Soup with Extra Caramelized Onions
Step 1: Caramelize Onions
In a large pot, melt 4 tablespoons of unsalted butter over medium heat. Add 4 cups of thinly sliced yellow onions and stir gently to coat. Cook for about 30-40 minutes, stirring occasionally, until the onions turn golden brown and develop a sweet aroma. The key to flavor is patience, so avoid raising the heat.
Step 2: Deglaze with Wine
Once the onions are beautifully caramelized, pour in 1 cup of dry white wine, scraping the bottom of the pot to lift all those tasty caramelized bits. Let it simmer for about 5 minutes until the wine reduces by half. This step will enhance the overall depth of flavor in your irresistible French onion soup.
Step 3: Add Broth and Thyme
Now, stir in 8 cups of rich beef broth and 2 teaspoons of fresh thyme (or 1 teaspoon dried thyme) into the pot. Increase the heat to bring the mixture to a gentle boil. Then, reduce the heat to low and allow it to simmer for another 30 minutes. This melding of flavors will create a savory base for your soup.
Step 4: Prepare Baguette
While the soup is simmering, preheat your oven to 400°F (200°C). Slice a baguette into thick pieces and toast them on a baking sheet until they are golden brown, about 10 minutes. Keep an eye on them to ensure they achieve that perfect crispiness to contrast the soup's velvety texture.
Step 5: Assemble and Broil
Divide the hot soup into oven-safe bowls, then carefully place the toasted baguette slices on top. Generously sprinkle 1-2 cups of shredded Gruyère cheese over the bread. Place the bowls under the broiler for about 5 minutes, or until the cheese is bubbly and golden brown. Watch closely to avoid burning, and enjoy the sight!
Step 6: Serve Immediately
Once your irresistibly rich French onion soup with extra caramelized onions is ready, carefully remove it from the oven. Allow it to cool slightly before serving. Pair with a simple side salad if desired, and savor every spoonful of this comforting delight that warms both the heart and the soul!

Expert Tips for Irresistible French Onion Soup
Caramelize Slowly: Patience is your friend! Caramelizing onions should take 30-40 minutes. Rushing will result in burnt onions rather than sweet, golden goodness.
Watch the Broiler: Keep a close eye on the broiler while melting the cheese. It only takes a minute to turn from perfect to burnt—trust me!
Customize Your Broth: For a vegetarian version, vegetable broth can easily replace beef broth without sacrificing flavor. It’s a great way to keep the soup deliciously comforting.
Fresh Herbs Matter: Fresh thyme adds delightful aromatic notes. If using dried thyme, remember to use only half as much for the best taste in this irresistible French onion soup.
Make Ahead: This soup stores well! Prepare it in advance and refrigerate for up to three days. Reheat gently with a splash of broth to keep the flavors intact.
