Essential Ingredients
Here’s what you’ll need to make this delicious dish:
- Onions: Sweet onions like Vidalia work best; their natural sugars caramelize beautifully for that classic flavor.
- Butter: Use unsalted butter to control the saltiness while adding richness to the broth.
- Beef Broth: For the best flavor, opt for high-quality beef broth; it adds depth and warmth to the soup.
- Thyme: Fresh thyme leaves bring an aromatic touch; dried thyme can work in a pinch but fresh is always better.
- Baguette: A crusty baguette is perfect; it holds up well when topped with cheese and broiled until crispy.
- Gruyère Cheese: This Swiss cheese melts beautifully and adds a nutty flavor; don’t skimp on the cheese!

Let’s Make it together
Sautéing Onions: In a large pot over medium heat, melt butter and add sliced onions. Cook until they turn golden brown and soft, stirring frequently for about 25 minutes. This step is crucial for developing that sweet flavor we adore!
Add Broth and Herbs: Pour in beef broth along with thyme and salt. Bring the mixture to a gentle simmer for about 20 minutes so those flavors meld together perfectly. Your kitchen will smell divine during this time!
Prepare Baguette Slices: While the soup simmers, preheat your oven to 400°F (200°C). Slice the baguette into thick pieces—about one inch—and place them on a baking sheet. Toast them in the oven until they are golden brown and crispy—this will be essential for spooning up that delicious soup!
Melt Gruyère Cheese: Ladle hot soup into oven-safe bowls and top each with toasted baguette slices and generous amounts of Gruyère cheese. Then place these bowls under the broiler until the cheese bubbles and turns golden brown—watch closely so it doesn’t burn!
Serve with Love!: Carefully remove from the oven (they will be hot!) and let cool slightly before serving. Garnish with extra thyme if desired and enjoy every comforting sip of your homemade French onion soup!
