Ingredients
Method
Preparation
- Peel and thinly slice your onions. A mandoline can help, but a sharp knife works perfectly.
Sauté
- In a large pot, melt the butter over medium heat.
- Add the sliced onions and cook, stirring frequently, until they are soft and caramelized, about 25-30 minutes.
Add Garlic and Broth
- Once the onions are caramelized, add the minced garlic and cook for an additional 2 minutes until fragrant.
- Pour in the beef broth along with thyme, bay leaf, salt, and pepper.
Simmer the Soup
- Bring the mixture to a boil, then reduce the heat and let it simmer for about 30 minutes.
Prepare Toppings
- While the soup is simmering, preheat your oven to broil.
- Arrange the toasted baguette slices on a baking sheet and top them with grated Gruyère cheese.
- Broil until the cheese is bubbling and golden brown.
Serve
- Remove the bay leaf from the soup, and ladle into bowls.
- Top each bowl with a cheesy baguette slice and enjoy your homemade Onion Soup!
Notes
Store leftover soup in an airtight container in the refrigerator for up to 4 days or freeze for up to 3 months. To reheat, warm on the stovetop over low heat or reseason and broil the baguette slices with cheese again before serving.
