How to Make Classic French Onion Soup
Now, the most important part of this soup recipe – the step-by-step instructions! They are written in very simple language so that even beginners can follow them. This is the authentic French method.
- In a large pot, heat the butter and olive oil over medium heat. Add the finely chopped onions and stir, then sprinkle with sugar. Cook slowly for 20-25 minutes, stirring occasionally, until the onions are golden brown and caramelized. Patience is key for great flavor – this step enhances the taste.
- Add the finely chopped garlic and sauté for 1-2 minutes until fragrant. Now add the white wine (if using) and let it simmer over high heat for 2-3 minutes to allow the alcohol to evaporate.
- Now add the vegetable broth, bay leaf, thyme, salt, and black pepper. Stir well and bring to a boil, then reduce the heat and simmer for 15-20 minutes to allow the flavors to meld. Taste and adjust the seasoning as needed.
- Preheat the oven to 200°C. Now pour the soup into oven-safe bowls. Place a slice of toasted baguette on top of each bowl and sprinkle generously with grated Gruyère cheese.
- Bake the ramekins in the oven for 5-7 minutes, until the cheese is melted and bubbling and the top is golden brown. Carefully remove them from the oven; they will be very hot, so be careful not to burn your fingers! Garnish with fresh herbs and serve immediately.🍲
If you follow all these steps carefully, your soup will turn out just like the one you get at a restaurant!

Storage Options
This soup is perfect for meal prep. Once the soup has cooled, pack it into an airtight container and store it in the refrigerator – it will stay fresh for 3-4 days. You can also freeze this soup for 1-2 months, but add the cheese topping separately when you reheat it. To reheat, use a low heat on the stovetop, adding a little broth if it has thickened. Avoid using the microwave if possible, as this can affect the soup’s texture. These methods will help you prevent food waste and allow you to enjoy this delicious soup whenever you like!
