Ingredients
This traditional French Onion Soup has warm baguettes topped with hot, melted Gruyere cheese. High quality beef broth, a splash of wine, and perfectly caramelized onions are the secrets to this classic recipe.
- 4 large yellow onions (see notes for pound conversion)
- 2 large sweet onions (Vidalia)
- 6 Tablespoons butter
- 2 sprigs fresh thyme
- 2 Bay leaves
- ¾ cup dry white wine (Chardonnay or Pinot Grigio)
- 3 tablespoons flour (optional)
- 4 cups beef broth (high quality is key)
- 1 beef bouillon cube (or 1 tsp Better Than Bouillon)
- 1.5 cups chicken broth

- Salt/Pepper (to taste)
- 1 baguette
- 3 Tablespoons olive oil (optional)
- 6 slices Gruyere cheese
How to Make French Onion Soup
Step 1: Slice the Onions
Slice the onions into ¼-inch slices; they should not be thinner. This thickness prevents them from becoming too stringy after cooking. Using a mandoline slicer will make this task much easier.
Step 2: Prepare the Butter
Melt the butter in a large soup pot or Dutch oven over medium-low heat. Wait until the butter begins to foam; this indicates that water has evaporated, leaving clarified butter that’s smooth.
Step 3: Cook the Onions
Add the sliced onions to the pot. Use tongs to toss and coat them thoroughly in the melted butter. Leave them uncovered while they cook.
Step 4: Caramelize Slowly
Caramelize the onions slowly over low heat for up to 2 hours or longer. Stir every 10–15 minutes. If you notice brown residue at the bottom of the pot, add a splash of wine and use a silicone spatula to scrape it up.
Step 5: Add Flour and Wine
When the onions are nearly done caramelizing, sprinkle flour over them and cook for an additional 2 minutes. Add any remaining wine and increase heat to medium-high. Toss more frequently until they turn richly brown and sweet.
Step 6: Combine Broths and Seasonings
Add beef broth, beef bouillon, chicken broth, Worcestershire sauce, bay leaves, and thyme to the pot. Simmer over medium heat for about 45 minutes with the lid slightly cracked.
Step 7: Preheat Oven
While your soup simmers away, preheat your oven to 350° F.
Step 8: Prepare Baguette Slices
Slice your baguette into ½-inch thick slices. Brush olive oil on top of each slice before baking them on a baking sheet for about 5 minutes.
Step 9: Top with Cheese
Increase oven temperature to 450° F. Place slices of Gruyere cheese on top of each baguette slice and bake until cheese melts and bubbles up nicely.
Step 10: Final Seasoning
Remove bay leaves and thyme stems from soup before seasoning with salt and pepper according to your taste preferences.
Step 11: Serve It Up!
Ladle warm soup into bowls and top each bowl with warm baguette slices laden with melted cheese. Enjoy your homemade French Onion Soup!
How to Serve French Onion Soup
French Onion Soup is best enjoyed hot, allowing the rich flavors of caramelized onions and melted Gruyere cheese to shine. Here are some delightful serving suggestions to elevate your dining experience.

Wine Pairings
- White Wine: A glass of Chardonnay or Pinot Grigio complements the flavors beautifully.
