Ingredients
4 large yellow onions, thinly sliced
3 tbsp unsalted butter
1 tbsp olive oil
1 tsp sugar (to aid in caramelization)
Salt and pepper to taste
4 cups beef broth (low sodium)
1 cup dry white wine (such as Sauvignon Blanc)
2 tbsp all-purpose flour
1 bay leaf
1 tsp fresh thyme (or ½ tsp dried thyme)
Baguette or crusty bread, sliced
1 ½ cups Gruyère cheese, grated (or a mix of Gruyère and Parmesan)
Instructions
Caramelize the Onions
In a large pot or Dutch oven, melt the butter and olive oil over medium heat. Add the sliced onions and sprinkle with a pinch of salt and sugar. Cook the onions slowly, stirring occasionally, for about 25-30 minutes, until they are golden brown and caramelized. Patience is key here; the slower you cook them, the better the flavor.
Add Flour
Once the onions are caramelized, sprinkle the flour over them and stir to coat. Cook for an additional 2-3 minutes to remove the raw flour taste.
Deglaze with Wine
Slowly pour in the white wine, scraping the bottom of the pot to loosen any browned bits. Allow the wine to simmer for about 5 minutes, letting the alcohol cook off.
Add Broth and Seasonings
Stir in the beef broth, bay leaf, and thyme. Bring the mixture to a simmer, then reduce the heat to low and let it cook for 20-30 minutes. Taste and adjust seasoning with salt and pepper.
Prepare the Bread
While the soup simmers, preheat your oven broiler. Place the sliced baguette on a baking sheet and toast under the broiler for about 1-2 minutes on each side, until golden brown.
Assemble and Broil
Remove the bay leaf from the soup and ladle it into oven-safe bowls. Place a toasted slice of bread on top of each bowl, then sprinkle generously with the grated Gruyère cheese. Place the bowls under the broiler for 2-4 minutes, or until the cheese is bubbly and golden brown.
Serve
Carefully remove the bowls from the oven (they will be hot!) and let them cool slightly before serving. Enjoy your comforting bowl of classic French onion soup!
Customization Ideas
Cheese Variations: While Gruyère is traditional, you can use Swiss cheese, mozzarella, or even a blend of cheeses for different flavors.
Add Herbs: Fresh herbs like parsley or chives can be sprinkled on top before serving for added flavor and color.
Make it Vegetarian: Substitute the beef broth with vegetable broth for a vegetarian version, and consider adding a splash of soy sauce or Worcestershire sauce for added depth.
Why It Works
The beauty of Classic French Onion Soup lies in its simplicity and depth of flavor. The slow caramelization of the onions brings out their natural sweetness, while the combination of beef broth and wine adds richness and complexity. The toasted bread and melted cheese on top create a satisfying texture contrast, making each spoonful a delightful experience.
Nutritional Benefits
Onions: Packed with antioxidants and vitamins, onions are great for heart health and can help reduce inflammation.
Broth: A good source of minerals and electrolytes, broth contributes to hydration and overall health.
Cheese: Provides protein and calcium, adding a satisfying richness to the soup.
Leftovers and Storage
This soup keeps well in the refrigerator for up to 3 days. However, it’s best to store the soup and bread separately to prevent the bread from becoming soggy. Reheat on the stove or in the microwave, and add freshly toasted bread and cheese before serving.
Perfect Pairings
Salad: A simple green salad with vinaigrette complements the richness of the soup.
Wine: Serve with a glass of the same white wine used in the recipe for a harmonious pairing.
Dessert: Finish off with a light dessert like a fruit tart or sorbet for a refreshing end to the meal.
Conclusion
Classic French Onion Soup is a timeless dish that embodies comfort and elegance. With its rich flavors and hearty ingredients, it’s perfect for any occasion, from casual family dinners to special gatherings. Make this recipe your own and enjoy the warmth and satisfaction that comes with every spoonful.
