French Onion Soup
Recipe
French onion soup is a classic French dish that has been enjoyed for centuries. The rich, savory broth and caramelized onions, topped with a thick layer of melted cheese, make this soup a truly comforting and satisfying meal.
Originating in Paris, this soup has become a staple in many restaurants and homes around the world. The key to its delicious flavor is the slow cooking of the onions, which allows them to develop a deep, sweet caramelization that perfectly complements the beef broth.
Ingredients:
- 4 large onions, thinly sliced
- 4 tablespoons unsalted butter
- 1 tablespoon olive oil
- 4 cloves garlic, minced
- 1/2 cup dry white wine
- 6 cups beef broth
- 2 sprigs fresh thyme
- 1 bay leaf
- Salt and freshly ground black pepper, to taste
- 1 baguette, sliced
- 1 1/2 cups grated Gruyère cheese
Instructions:
In a large pot or Dutch oven, melt the butter with the olive oil over medium-low heat. Add the sliced onions and cook, stirring occasionally, for about 30-40 minutes, until the onions are very soft and caramelized.
Add the garlic and cook for an additional 2-3 minutes, until fragrant.
Deglaze the pan with the white wine, scraping up any browned bits from the bottom. Allow the wine to simmer until reduced by half.
Add the beef broth, thyme, and bay leaf. Bring the soup to a simmer and cook for 30 minutes, seasoning with salt and pepper to taste.
Tips:
To achieve the perfect caramelization on the onions, be patient and allow them to cook slowly over low heat. This may take up to an hour, but the rich, sweet flavor is well worth the time.
For the best texture, be sure to slice the onions thinly. When serving, top each bowl of soup with a slice of toasted baguette and a generous layer of grated Gruyère cheese.
Place the bowls under the broiler for a few minutes, until the cheese is melted and bubbly.
Cooking Steps
Slice the onions into thin rings and get ready to caramelize them over low heat.
Once the onions are nice and golden brown, it's time to add the savory broth.
Step 1. Slice Onions Into Thin Rings
Carefully peel the onions, revealing their glistening layers. Hold each onion steady on your cutting board, then grab your sharpest knife and begin slicing.
Work slowly and with focus, creating thin, even rings that will cook down to a meltingly tender texture. The onion's distinct aroma fills the air as you work, making your mouth water in anticipation.
Try to keep the slices uniform, about 1/4-inch thick, for even cooking. As you layer the rings into your pot, notice how the delicate, translucent pieces glisten.
Soon, these simple onion slices will transform into the rich, savory base of your French onion soup. Keep slicing until you've worked your way through all the onions, creating a generous pile ready to caramelize and deepen in flavor.
With your prep work complete, you're one step closer to enjoying a steaming bowl of comfort.
Step 2. Caramelize Onions Over Low Heat
With your pile of delicately sliced onion rings ready, it's time to start the caramelization process. In a large skillet, melt a generous amount of butter over low heat. Carefully place the onions into the pan, making sure they're in a single layer. As the butter sizzles, the onions will start to soften and turn a light golden color.
Be patient and stir the onions occasionally, allowing them to cook slowly. The low heat is crucial – it'll take about 30 minutes for the onions to fully caramelize. As they cook, you'll notice the onions shrinking down and releasing their natural sugars, creating a rich, sweet flavor.
Keep a close eye on the pan, adjusting the heat as needed to prevent the onions from burning. The goal is a deep, mahogany-colored caramelization, not charred onions.
Breathe in the heavenly aroma wafting through your kitchen – it's the first step to creating an authentic French onion soup!
Step 3. Add the Broth
After the onions have caramelized to perfection, it's time to add the broth. Grab your favorite broth – whether it's beef, chicken, or even vegetable, it's going to give your soup an incredible flavor boost.
Slowly pour the broth into the pot, letting it sizzle and steam as it meets the caramelized onions. You'll start to smell the aroma of the broth mingling with the sweet, savory onions, and your mouth will be watering in no time. For an even deeper flavor profile, consider using a broth fortified with air purifier features and technologies that help improve your kitchen's air quality while cooking.
Stir the broth gently, making sure to scrape up any bits of onion stuck to the bottom of the pot. This will add even more flavor to your soup.
Let the broth come to a gentle simmer, then reduce the heat and let it cook for about 15 minutes. This allows the flavors to meld together perfectly.
Now your soup is ready for the next step – adding the cheesy croutons on top! Get ready for a cozy, comforting bowl of French onion soup.
Step 4. Add Croutons and Cheese
The cheesy croutons are the crowning glory of this classic French onion soup. Once the rich broth has simmered to perfection, it's time to add the final touches.
Grab a handful of crispy, golden-brown croutons and gently float them on top of the steaming soup. As they soak up the savory broth, the croutons will become soft and delectable.
Next, generously sprinkle shredded Gruyère or Emmentaler cheese over the croutons. The cheese will melt into a bubbly, golden blanket, creating the ultimate in cheesy comfort.
The contrast of the crunchy croutons and the melted cheese is simply irresistible. With each spoonful, you'll savor the perfect blend of flavors and textures.
The cheesy croutons add the final touch to this beloved French classic, making it an indulgent and satisfying meal.
Dig in and enjoy every last bite of this cozy, comforting soup!
Step 5. Broil Topped Soup to Melt Cheese
Preheat your oven's broiler to a high setting. Once it's nice and hot, grab your oven-safe bowls filled with your delicious French onion soup. Carefully place them onto a baking sheet, making sure they're evenly spaced.
Next, generously top each bowl with those golden, bubbly croutons you made earlier. Didn't they turn out great?
Now, sprinkle the shredded Gruyère or Swiss cheese all over the top. You want to cover every inch, so the cheese will melt into every nook and cranny.
Slide the baking sheet under the broiler and let the magic happen! Keep a close eye, as the cheese will quickly transform into a beautiful, melty blanket.
Once it's golden brown and irresistible, carefully remove the bowls from the oven. Be cautious, as the bowls will be very hot. Serve immediately and enjoy that first heavenly spoonful of steaming hot soup with the perfect cheese topping!
Final Thoughts

While enjoying this comforting dish, you might also appreciate the fact that comfort foods like soup often lead to increased cravings for other delightful treats, such as ice cream, especially during peak ice cream consumption in the summer months.
