How to Make Authentic French Onion Soup
Let’s embark on this flavorful journey together! Follow these simple steps to create your delicious soup:
-
In a large pot, heat the butter and olive oil over medium heat. Once melted, add the sliced onions and cook slowly, stirring occasionally, for 40–50 minutes until they are deep golden brown and caramelized. This step is crucial for developing that rich flavor!
-
Stir in the minced garlic and cook for another minute until fragrant, allowing those lovely aromas to fill your kitchen.
-
Pour in the white wine (or substitute) to deglaze the pan, scraping up any of the delightful brown bits at the bottom. Let it simmer for 5–7 minutes until the alcohol evaporates.
-
Add the beef broth, thyme, and bay leaves. Lower the heat and let the soup simmer for 30–40 minutes. Afterward, season with salt and pepper to taste. Remember to discard the thyme and bay leaves before serving.
-
While the soup is simmering away, preheat your oven and toast the baguette slices until they are golden and crisp, giving them that satisfying crunch.
-
Ladle the hot soup into oven-safe bowls. Top each bowl with a slice of toasted baguette and a generous amount of Gruyère cheese. Don’t be shy; more cheese means more joy!
-
Place the bowls under the broiler for 2–4 minutes until the cheese is bubbly and golden brown, like the beautiful sunset it deserves to be.
-
Serve hot, optionally garnished with a sprig of thyme or a sprinkle of fresh ground pepper for that extra flair.
Delicious Variations to Try
While the classic version of French onion soup is absolutely perfect, here are a few scrumptious twists you might want to experiment with:
- Mushroom Medley: Sauté some mushrooms along with the onions for an earthy, zesty flavor.
- Herb Infusion: Add a pinch of rosemary or sage to the broth for a fragrant herbal note.
- Creamy Version: Stir in a splash of cream before serving for a rich, velvety texture.
- Cheesy Bliss: Try mixing different cheeses like mozzarella or Fontina for a unique flavor twist.
Chef Emma’s Helpful Tips

Slow & Steady: Don’t rush the caramelization process! Low and slow is key to unlocking the natural sweetness in onions.

Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Just remember, the bread should be added just before serving to maintain its crispness.
-
Ingredient Swaps: If you’re vegetarian, substitute the beef broth with vegetable broth for a lighter but equally delicious version.
