Equipment
- Heavy-bottomed pot or Dutch oven
- Wooden spoon
- Cheese grater
- Oven-safe soup bowls
Ingredients
- 6 large Yellow onions thinly sliced
- 3 tablespoons Unsalted butter
- 2 tablespoons Olive oil
- 8 cups Beef stock
- 2 Bay leaves
- 6 sprigs Fresh thyme
- 12 slices Baguette
- 1 1/2 cups Gruyère cheese shredded
- Salt and pepper to taste
Instructions
Step 1 – Prepare the Onions
- Peel and thinly slice the onions.
- In your Dutch oven, melt the butter with the olive oil over medium heat.
- Add the onions and cook, stirring frequently, until they are deeply caramelized, about 45 minutes.
- Note: Caramelizing onions slowly and gently is key to unlocking their natural sweetness.
Step 2 – Simmer the Soup
- Once the onions are caramelized, add the beef stock, bay leaves, and thyme.
- Bring to a boil, then reduce the heat and simmer for 30 minutes.
- Remove the bay leaves and thyme, then season with salt and pepper to taste.
- Warning: Be careful not to burn the onions as it can give the soup a bitter taste.
Step 3 – Broil the Cheese Topping
- Preheat your broiler.
- Ladle the soup into oven-safe bowls.
- Top each with two slices of baguette and a generous amount of shredded Gruyère.
- Broil until the cheese is bubbly and golden brown, about 3-5 minutes.
- Note: Keep a close eye on the soup under the broiler as the cheese can burn quickly.
Notes
- Onion Choice: Yellow onions are recommended for their perfect balance of sweet and sharp flavors.
- Cheese Options: If you can’t find Gruyère, Swiss or mozzarella can be decent substitutes, though Gruyère is traditional for its nutty flavor.
