Step-by-step instructions
- Melt the butter and olive oil: In a large pot, combine the butter and olive oil over medium heat until melted.
- Cook the onions: Add the sliced onions, salt, and sugar. Cook them while stirring occasionally until they caramelize; this will take about 30 minutes. Patience is key here!
- Simmer: Once the onions are beautifully golden, pour in the beef broth, white wine, thyme, and bay leaf. Bring this to a simmer and cook for another 20-30 minutes to deepen the flavors.
- Preheat oven: While the soup simmers, preheat your oven to 350°F (175°C).
- Toast baguette slices: Arrange the baguette slices on a baking sheet and toast them in the oven for about 10 minutes until golden.
- Assemble the soup: Remove the bay leaf from the pot and ladle the soup into oven-safe bowls. Top each bowl with a baguette slice and generously sprinkle with Gruyère cheese.
- Broil: Place the bowls back on the baking sheet and broil them in the oven until the cheese is bubbly and golden, roughly 3-5 minutes.
- Enjoy: Serve your piping hot French Onion Soup and enjoy every delicious sip!
Best ways to enjoy it
When serving French Onion Soup, consider pairing it with a simple green salad dressed in a tangy vinaigrette to balance the richness of the cheese. A glass of crisp white wine complements the soup beautifully, enhancing its flavors. For a more rustic touch, sprinkle fresh herbs like parsley or chives on top before serving for a pop of color and freshness!
Keeping leftovers fresh
If you find yourself with leftovers (if that’s even possible!), store the soup in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm it on the stove over medium heat, and you can toast fresh baguette slices to top it again for that delightful crispness!
For longer storage, consider freezing the soup (without the bread and cheese) in freezer-safe containers for up to 3 months. Just remember to cool it completely before freezing.
Helpful cooking tips
- Patience is key: The key to perfect caramelized onions is cooking them low and slow. Don’t rush the process, as it builds flavor.
- Wine choice: Use a dry white wine that you enjoy drinking. A sauvignon blanc or a Pinot Grigio works wonderfully.
- Broil carefully: When broiling, keep an eye on the cheese. It can go from bubbling to burned quite quickly!
Creative twists
Feeling adventurous? Try adding different herbs such as rosemary or a splash of sherry for an elevated flavor profile. You can also experiment with different cheeses—Comté or even a sharp cheddar can add a delightful twist. For a kick, consider incorporating a bit of cooked bacon or pancetta in the soup for an added layer of richness and depth.
