Traditional French Onion Soup is a comforting, savory soup with sweet caramelized onions, rich beef broth, and a cheesy toasted bread topping 🧅🍲🧀
🥄 Ingredients
- 4–5 large onions, thinly sliced
- 4 tbsp butter (or butter + oil)
- 1 tsp sugar (to help caramelize onions)
- 1–2 cloves garlic, minced
- 6 cups beef broth (or a mix of beef & chicken broth)
- 1–2 tbsp flour (optional, for slightly thicker soup)
- Salt & pepper to taste
- 1 tsp thyme or 1 bay leaf
- Baguette slices, toasted
- 1–2 cups grated Gruyère or Swiss cheese
🔥 How to Make It
1. Caramelize Onions
- Melt butter in a large pot over medium heat.
- Add onions and sugar.
- Cook 30–40 minutes, stirring occasionally, until deep golden brown.
2. Add Garlic & Flour
- Stir in garlic and optional flour; cook 1–2 minutes.
3. Add Broth & Herbs
- Pour in beef broth.
- Add thyme or bay leaf, salt, and pepper.
- Simmer 20–25 minutes to let flavors meld.

😋 Tips for Best Flavor
- Low and slow caramelization → the key to sweet, rich onion flavor.
- Use a dry white wine or sherry during step 3 for extra depth.
- Stir occasionally to prevent burning.
