Ingredients

  • 1 tablespoon butter
  • 1 teaspoon vegetable oil, extra virgin
  • 2 medium onions, sliced
  • 1 clove garlic, chopped
  • 0.25 teaspoon dry thyme
  • 0.25 teaspoon dry basil
  • 1 bay leaf
  • 1.5 tablespoons flour
  • 1 tablespoon tomato paste
  • 2 cups beef stock
  • 1 cup water
  • Salt and fresh ground black pepper, to taste

GARNISH

  • 8 slices French baguette
  • 0.5 cup Gruyere cheese, grated

Instructions

Make the onion soup:

  • Melt butter in a 4-quart saucepan. Stir in sugar. Add onions and cook over medium heat for 10 minutes, or until golden brown. When the onion juices start to brown and stick to the bottom of the pot, deglaze with a 1/2 cup of water and stir well. This will prevent the onions from burning and will transfer the color from the bottom of the pot to the sliced onions.
  • Stir in flour until well blended with the onions and pan juices. Add tomato paste and cook for 2 minutes. Add water, wine, and white beef stock; heat to boiling. Reduce heat to low. Cover soup, and simmer for 15 minutes.

Make the garnish:

  • While the soup is simmering cut baguette into slices. Toast it using the broil function of your oven or a bread toaster

Serve the onion soup:

  • Ladle soup into four 12 ounces, oven-safe bowls. Place 2 slices toasted bread, side by side, on top of the soup in each bowl. Cover toasted bread with grated Swiss cheese. Place soup bowls on a cookie sheet for easier handling.
  • Bake at 425 °F (220 ° C) for 10 minutes, or just until the cheese is melted and golden brown.

Notes

Brown skin onions are usually referred to as Spanish onions. You may use brown and white onions to make the recipe, it will slightly change the flavor but it will remain tasty.

Cooking Tips for the Best French Onion Soup:

  • Caramelize the onions slowly: This is a crucial step for French onion soup. Cook the onions over low to medium heat, stirring occasionally. This allows the natural sugars to develop, giving the soup its signature sweet and savory depth of flavor.
  • Use a good quality beef stock: Since the broth is the base of the soup, using a rich, flavorful beef stock or broth will make a big difference in the taste.
  • Toast the bread slices: For the perfect topping, toast the bread slices until they’re golden and crispy. This ensures they don’t become soggy once the cheese and soup are added.
  • Grate the cheese: Freshly grated Gruyère or Swiss cheese melts better and gives the soup a smoother texture than pre-grated varieties.
  • Simmer the soup: Let the soup simmer for at least 15 minutes to allow the flavors to meld. You can let it simmer longer for a deeper, more developed flavor.

With these tips, you’ll be able to create a rich, flavorful French onion soup that will delight your guests or family. Enjoy!
