For the Soup:

• Yellow Onions: The star of the show! Caramelized onions provide that rich, sweet, and savory flavor that makes French onion soup so irresistible.
• Butter: A bit of butter is essential for sautéing the onions and helping them soften and caramelize, giving the soup a rich, silky base.
• Garlic: A couple of cloves of garlic add a lovely aromatic flavor to complement the onions.
• Beef Broth: This is the broth of choice for authentic French onion soup, adding a deep, savory flavor to the base.
• Thyme: Fresh thyme sprigs bring a subtle earthy note that enhances the soup’s richness.
• Bay Leaf: A couple of bay leaves add depth to the broth, giving it that signature French onion soup flavor.
• Salt and Pepper: To season the soup to taste and bring all the flavors together.

For the Topping:

• Baguette: A few slices of crusty baguette are toasted and placed on top of the soup to create the perfect base for the cheese.
• Gruyère Cheese: This Swiss cheese is the traditional choice for French onion soup. It melts beautifully and adds a nutty, creamy flavor.
• Parmesan Cheese: A sprinkle of Parmesan on top adds an extra layer of richness and a bit of sharpness to balance out the sweetness of the onions.

Instructions

1. Caramelize the Onions
   In a large pot, melt the butter over medium heat. Add the sliced onions and a pinch of salt. Cook, stirring occasionally, for about 20-25 minutes until the onions become soft and golden brown. Be patient—this slow process of caramelization brings out the natural sweetness of the onions.
2. Add the Garlic and Herbs
   Once the onions are caramelized, add the garlic and cook for another minute until fragrant. Add the thyme sprigs and bay leaves to the pot.
3. Add the Broth
   Pour in the beef broth, stirring to combine. Bring the soup to a simmer and cook for another 20-25 minutes, allowing the flavors to meld together. Taste and adjust seasoning with salt and pepper.
4. Prepare the Toasted Baguette
   While the soup is simmering, preheat your oven to 400°F (200°C). Arrange the baguette slices on a baking sheet and toast them in the oven for about 5-7 minutes, or until golden and crispy.
5. Assemble the Soup
   Once the soup is ready, remove the bay leaves and thyme sprigs. Ladle the soup into oven-safe bowls. Top each bowl with a toasted baguette slice and a generous amount of Gruyère and Parmesan cheese.
6. Melt the Cheese
   Place the bowls under the broiler for 2-3 minutes, or until the cheese is melted and bubbly, with golden brown spots on top.
7. Serve & Enjoy
   Remove the bowls from the oven carefully, as they’ll be hot. Serve immediately, and enjoy the warm, comforting flavors of your homemade French onion soup!
