Best French Onion Soup Recipe: A Chef Shares Her Favorite Easy French Onion Soup Recipe

If you're anything like me – you’re always short on time, but long on flavor. Then this French onion soup recipe is perfect for you. This easy French onion soup recipe is so rich and delicious, you'll never believe how simple it is to make. It's one of my family's favorite meals for lunch or dinner, and I hope it will become one of your family faves, too!

Cuisine: French
Prep Time: 15 minutes
Cook Time: 30 minutes
Total Time: 45 minutes
Servings: 8


  • 1/2 cup unsalted butter
  • 2 tablespoons olive oil
  • 4 large onions, sliced thin
  • 2 garlic cloves, chopped
  • bay leaves
  • 2 fresh thyme sprigs
  • 1 cup red wine, about 1/2 bottle (optional)
  • 4 tablespoons flour
  • 2 quarts beef broth
  • 1 sweet baguette, sliced in 1-inch diagonal slices
  • 1/2 pound grated Gruyere (or your favorite Swiss cheese)
  • 1/4 cup fresh parsley, chopped fine for garnish (optional)

Here's how you make it:

  1. In a stock pot over medium heat, melt the butter and oil. Add the onions, garlic, bay leaves, thyme, and salt and pepper. Cook until the onions are deep brown and caramelized, 10-15 minutes.
  2. Add the wine and bring to a boil. Reduce heat and simmer until the wine has evaporated and the onions are dry, about 5 minutes. Remove the herbs.
  3. Dust the onions with the flour and stir. Reduce heat to medium low so the flour doesn’t burn and cook about 5 minutes. Add the beef broth slowly while stirring to avoid lumping. Return soup to a simmer. Season to taste with salt and pepper.
  4. Toast sliced baguettes until nicely brown. Rub each piece of toasted baguette with fresh cut garlic. Set aside.
  5. When ready to serve, preheat the oven to broil. Place the soup bowls in a roasting pan and ladle the soup into bowls. Top each bowl with 2 slices of bread and then a handful of grated Gruyere. Sprinkle fresh parsley on top, if desired. Place in the oven to toast the bread and melt the cheese. Serve.
