It's known for its rich, caramelized onions and savory beef broth, topped with bubbly, melted Swiss cheese and accompanied by crispy baguette slices. Perfect for a comforting meal on a cold day, this recipe brings together unique flavors and textures to create a delicious and satisfying soup.

Ingredients:

8 cups beef broth
1920g
1/3 cup swiss cheese
36g
2 tbsp butter
27g
5 onions onion
550g
1 garlic clove
3g
2 dash black pepper
0.20g
2 tbsp fresh parsley
8g
1/8 cup all-purpose white wheat flour
16g
2 dash salt
0.80g
8 slices baguette (french bread)
510g

Instructions:

1. Prep the Onions:
- Peel and thinly slice the onions.
- Mince the garlic clove.
2. Caramelize the Onions:
- In a large pot, melt the butter over medium heat.
- Add the sliced onions and cook, stirring occasionally, until they turn a deep golden brown, about 25-30 minutes. Be patient; caramelizing onions properly takes time but is key to the soup’s depth of flavor.
3. Cook the Garlic:
- Add the minced garlic to the pot and cook for another 1-2 minutes until fragrant.
4. Thicken the Soup:
- Sprinkle the flour over the caramelized onions and garlic. Stir well to coat the onions with the flour. Cook for about 2 minutes to remove the raw flour taste.
5. Add Broth and Seasonings:
- Gradually add the beef broth, stirring constantly to avoid lumps.
- Add the black pepper and salt.
6. Simmer:
- Bring the soup to a simmer and let it cook for another 20-30 minutes, allowing the flavors to meld together.
7. Prepare the Baguette:
- While the soup is simmering, preheat your oven to 350°F (175°C).
- Place the baguette slices on a baking sheet and toast them in the oven for about 5-7 minutes or until they are crisp and golden brown. You can alternatively broil them for 1-2 minutes if you prefer.
8. Serve:
- Ladle the hot soup into oven-safe bowls.
- Place a toasted baguette slice (or two, depending on the size) on top of each bowl of soup.
- Sprinkle the shredded Swiss cheese generously over the baguette slices.
9. Broil:
- Place the bowls on a baking sheet and transfer them to the broiler. Broil for about 2-3 minutes, or until the cheese is melted and bubbly.
10. Garnish:
- Remove the bowls carefully from the oven (they will be hot!).
- Garnish the soup with freshly chopped parsley.
11. Serve and Enjoy:
- Serve immediately, being careful as the bowls will be very hot.
- Enjoy your delicious homemade French Onion Soup with Swiss Cheese and Baguette!

Tips:

- To caramelize the onions, cook them on medium heat while stirring occasionally. This process can take around 30-40 minutes but is crucial for bringing out the deep, sweet flavors.

- For an extra depth of flavor, you can deglaze the pot with a bit of dry white wine or sherry after caramelizing the onions.

- Use a good quality beef broth for the best flavor. Homemade broth will yield the best results, but store-bought broth can also be used.

- Toast the baguette slices lightly before adding them to the soup to prevent them from becoming too soggy.

- If you prefer, you can also use gruyere cheese instead of Swiss cheese for a slightly different flavor profile.
