Ingredients You’ll Need
The magic really starts with the onions — their caramelization is the star. Pair that with savory beef broth and a splash of white wine, then finish with toasted baguette slices and melty Gruyere. These ingredients all work in harmony to create the classic flavors you expect from an authentic French onion soup.

- Baguette: Toasted slices create a sturdy, crunchy base for the cheese topping.
- Gruyere Cheese: Classic, nutty, and melts beautifully — you’ll want it bubbly and browned.

Variations
I love playing around with this recipe depending on what I have on hand or who I’m cooking for. Sometimes I add a mix of different onion types or swap cheeses to switch up the flavor. Feel free to make it your own!
- Cheese Variety: I’ve used Emmental or Swiss when I wanted a milder, creamier melt, and it’s just as delicious.
- Wine-Free Version: For days I skip alcohol, I substitute the white wine with extra beef broth plus a dash of vinegar; it still tastes fantastic.
- Vegetarian Twist: Swap beef broth for mushroom or vegetable broth and use a vegetarian cheese for a meat-free version.
- Extra Herbs: I sometimes add a pinch of fresh rosemary or a sprinkle of parsley at the end for extra aroma.
How to Make Easy French Onion Soup with Melted Cheese Recipe
Step 1: Slowly Caramelize Your Onions
Start by heating butter and olive oil in a large skillet with high sides over medium heat. Add your thinly sliced onions along with fresh thyme leaves stripped from the sprigs and a bay leaf. Here’s the key: cook the onions gently on low heat, stirring every 10 minutes or so. This slow caramelization process takes patience—expect it to take about 45 minutes to reach that perfect deep golden-brown. Don’t rush it or crank the heat — you want sweet, rich flavor, not burnt onion bitterness. A sprinkle of salt early on helps draw out moisture and enhances the caramelization.
Step 2: Deglaze and Simmer the Soup
Once your onions turn that beautiful deep caramel color, deglaze the pan with white wine, scraping those tasty browned bits off the bottom. Turn up the heat so the wine boils and the alcohol cooks off, leaving behind just the flavor. Then add your beef broth, bring the soup back to a boil, and reduce to a gentle simmer. Let all those flavors mingle for a few minutes while you preheat your broiler. Taste and add salt and pepper to get it just right.
Step 3: Prepare for Broiling with Toast and Cheese
Ladle the rich soup into oven-safe bowls—make sure these can handle the broiler heat! Top each bowl with a toasted baguette slice. Then, pile on the grated Gruyere cheese generously. This step feels fun because it’s the promise of that ooey-gooey, golden cheese crust you know and love.
Step 4: Broil Until Cheese is Golden and Bubbly
Pop your bowls under the broiler for about 3-5 minutes. Keep a close watch—cheese can go from beautifully bubbly to burnt fast! You want that perfect golden-brown crust with a little crisp edge. When it’s ready, carefully remove from the oven and feel free to garnish with extra fresh thyme leaves for a lovely herbal touch.
Pro Tips for Making Easy French Onion Soup with Melted Cheese Recipe
- Be Patient With Your Onions: I used to rush this part and the flavor just wasn’t the same. Let those onions brown low and slow—it’s the soul of the soup.
- Choose Your Cheese Wisely: Gruyere melts like a dream and tastes divine, but mixing it with a bit of Emmental can add an extra creamy, nutty layer.
- Watch the Broiler: Your cheese goes from perfect to burnt in seconds—stand close and keep an eye on those bowls!
- Skip the Wine if Needed: I’ve done this swap for family dinners, and adding a splash of vinegar to beef broth keeps the flavor balanced when you can’t use alcohol.
How to Serve Easy French Onion Soup with Melted Cheese Recipe
Garnishes
I usually keep it simple with extra fresh thyme leaves scattered on top for color and that fresh aroma. Sometimes a little cracked black pepper or a tiny sprinkle of fresh parsley works great too—just to brighten the presentation and flavor.
Side Dishes
My family goes crazy for this soup alongside a crisp green salad with a tangy vinaigrette—it cuts through the richness nicely. A plate of roasted veggies or a charcuterie board also pairs beautifully for a heartier meal.
Creative Ways to Present
For special occasions, I like serving the soup in individual mini Dutch ovens or rustic crocks—they look charming on a table set for guests. You can even sprinkle some smoked paprika on the cheese before broiling for a subtle smoky flair that surprises everyone.
Make Ahead and Storage
Storing Leftovers
I store leftover soup without the bread and cheese in airtight containers in the fridge. It keeps beautifully for up to 3 days. When you’re ready, just reheat gently.
Freezing
French onion soup freezes well, especially if you leave out the toasted bread and cheese before freezing. I portion mine into freezer-safe containers and it’s a lifesaver for quick dinners on busy nights.
Reheating
I like to warm the soup slowly on the stovetop, then add a fresh toasted baguette slice and reheated grated cheese under the broiler for a quick fresh finish. This way, it tastes almost as good as freshly made.
FAQs
-
Can I make Easy French Onion Soup with Melted Cheese Recipe without beef broth?
Absolutely! If you prefer a vegetarian version, you can use a rich vegetable or mushroom broth instead. It won’t have quite the same deep meaty flavor but still makes a delicious and comforting soup.
-
What’s the best cheese for topping French onion soup?
Gruyere is the classic choice for its perfect melting qualities and nutty flavor. You can also use Emmental, Swiss, or even a blend of cheeses for added depth. Just make sure they melt well and brown nicely under the broiler.
-
How long does it take to caramelize onions properly?
It generally takes about 45 minutes of slow cooking over low heat to get onions deeply caramelized, stirring every 10 minutes. Rushing this step can lead to uneven cooking or burnt bits, so patience is key for that amazing flavor.
-
Can I prepare the soup ahead of time?
Yes! You can make the soup base ahead and refrigerate it without the bread and cheese for a day or two. Add the toasted baguette and cheese right before serving, then broil for the best melt and crust.
-
How do I prevent the cheese from burning under the broiler?
Keep a very close eye on your bowls when under the broiler, since the cheese can burn quickly. Broil in short intervals of 1-2 minutes, checking frequently until the cheese is melted and just turning golden brown.

Perfect for a cozy meal, this recipe combines slow-cooked onions with the broiled cheesy topping to deliver a comforting French bistro experience at home.
Ingredients
Onion Soup Base
- 6 cups thinly sliced onions
- 2 tablespoons butter
- 2 tablespoons olive oil
- 6 sprigs fresh thyme
- 1 bay leaf
- ½ cup white wine
- 4 cups high-quality beef broth
- salt and pepper to taste
Toppings
- 4 slices baguette, toasted
- 1 ½ cups grated Gruyere or similar cheese
Instructions
- Caramelize the Onions: In a large skillet with high sides, heat the butter and oil over medium heat. Add the sliced onions, thyme leaves (removed from sprigs), and bay leaf. Cook the onions on low heat until they are deeply caramelized, stirring every 10 minutes to prevent sticking, and adding a teaspoon of salt. This process takes up to 45 minutes and is essential to develop the soup’s rich flavor.
- Deglaze and Simmer: Once the onions are a deep caramel color, deglaze the pan with the white wine. Increase the heat to bring the mixture to a boil, allowing the alcohol to evaporate. Add the beef broth, bring the soup back to a boil, then reduce the heat and let it simmer. Taste and adjust the seasoning with salt and pepper.
- Prepare for Broiling: Ladle the soup into four oven-safe bowls. Top each bowl with a toasted slice of baguette. Divide the grated cheese evenly among the bowls, ensuring each has a generous amount on top.
- Broil the Soup: Place the bowls under the preheated broiler until the cheese is melted, golden, and bubbly, about 3-5 minutes. Watch closely to avoid burning the cheese.
- Garnish and Serve: Garnish each bowl with additional fresh thyme leaves if desired. Serve immediately and enjoy your classic French Onion Soup.
Notes
- Onion Choice: Yellow onions are traditional, but using a mix of yellow, white, and red onions adds complexity to the flavor.
- Wine Substitute: If you prefer not to use wine, substitute with an equal amount of beef broth plus a splash of vinegar to maintain acidity.
- Cheese Options: Gruyere is classic, but Emmental, Swiss, or a combination of cheeses also work well.
- Broiler Tip: Always watch closely when broiling to prevent the cheese from burning.
