Step-by-Step Instructions for Classic French Onion Soup
  1. Begin by slicing 1 kg of yellow onions into thin half-moons. Set aside for caramelization.
  2. In a large pot, combine 2 tablespoons of butter and 2 tablespoons of olive oil over medium heat. Allow to melt.
  3. Add the sliced onions and stir gently to coat them in the buttery mixture.
  4. Cook the onions for 40-50 minutes until golden brown and caramelized.
  5. Add 2 finely chopped garlic cloves to the pot and sauté for 1 minute.
  6. Pour in 1.5 liters of beef broth, along with 2 bay leaves and 3 sprigs of fresh thyme. Bring to a boil.
  7. Lower the heat and let the soup simmer for 20 minutes.
  8. Preheat the oven to 400°F (200°C). Arrange baguette slices on a baking sheet and toast for 5-7 minutes.
  9. Ladle the hot soup into oven-safe bowls, add a toasted baguette slice, and sprinkle with cheese. Broil for 5-7 minutes.
  10. Serve immediately after removing from the broiler, paired with a green salad.
