Ingredients & Preparation Notes

- Garlic: Freshly minced garlic adds a subtle depth of flavor. Add it towards the end of caramelizing the onions to prevent it from burning.
- White Wine: This is optional but adds a nice acidity to balance the soup’s richness. You can substitute it with more vegetable broth if preferred.
- Vegetable Broth: Opt for a low-sodium version to control the saltiness of the soup.
- Thyme and Bay Leaf: These herbs enhance the soup’s flavor. Fresh thyme is preferable, but dried works well too.
- Baguette and Gruyère Cheese: For the perfect topping, use a crusty baguette and high-quality Gruyère cheese. Swiss cheese can be a good substitute if needed.
Professional Tips & Techniques
- Caramelization is Key: The secret to a flavorful French Onion Soup lies in the slow caramelization of the onions. This process can take up to 40 minutes, but it’s worth it for the deep, sweet flavor it imparts.
- Deglaze the Pan: After caramelizing the onions, deglaze the pan with white wine or broth to lift all the flavorful bits from the bottom. This step adds complexity to the soup.
- Temperature Control: Keep the heat at medium-low during caramelization to prevent burning. Stir occasionally to ensure even cooking.
- Broiling the Cheese: When broiling the cheese-topped soup, watch it closely to prevent burning. The cheese should be bubbly and golden brown.
- Visual Cues for Doneness: The soup is ready when the onions are soft and the broth is rich and flavorful. The cheese should be melted and slightly browned on top.
Recipe Variations
- Vegan French Onion Soup: Substitute the butter with vegan butter and use a dairy-free cheese alternative or skip the cheese altogether.
- Gluten-Free Option: Use gluten-free bread for the topping to make this soup suitable for those with gluten sensitivities.
- Mushroom French Onion Soup: Add sliced mushrooms during the caramelization process for an earthy twist.
- Herb-Infused Broth: Experiment with different herbs like rosemary or sage to give the soup a unique flavor profile.
- Cheese Variations: Try using a mix of cheeses like Gruyère and Parmesan for a more complex flavor.
- Spicy Kick: Add a pinch of red pepper flakes or a dash of hot sauce for a spicy version of this classic soup.
- Creamy French Onion Soup: Stir in a splash of heavy cream or coconut milk for a creamier texture.
- Seasonal Adaptations: In the summer, use fresh, sweet onions for a lighter flavor; in the winter, use heartier onions for a more robust soup.

Method
- In a large pot or Dutch oven, melt the butter and olive oil over medium heat. Add the onions and sugar, stirring to coat. Cook, stirring occasionally, for about 10 minutes until the onions begin to soften.
- Reduce the heat to medium-low and continue cooking the onions for another 30-40 minutes, stirring occasionally, until they are deeply caramelized and golden brown. The key here is patience; the slow cooking process allows the onions to develop a rich, sweet flavor.
- Once the onions are caramelized, add the garlic and cook for another 1-2 minutes until fragrant. Pour in the white wine (if using) and deglaze the pan, scraping up any browned bits from the bottom.
- Add the vegetable broth, thyme, and bay leaf. Bring the soup to a simmer, then reduce the heat to low and let it cook for another 20 minutes to allow the flavors to meld. Season with salt and pepper to taste.
- Preheat your broiler. Ladle the soup into oven-safe bowls, top each with a slice of toasted baguette and a generous amount of Gruyère cheese. Place the bowls on a baking sheet and broil for 2-3 minutes until the cheese is melted and bubbly.
- Carefully remove the bowls from the oven and let them cool slightly before serving. Enjoy your rich and comforting Vegetarian French Onion Soup!
