Ingredients

  • 2 Tablespoons unsalted butter
  • 2 yellow onions, halved, thinly sliced into half-moons
  • Kosher salt, to taste
  • Large pinch sugar
  • 1/2 Cup beef stock
  • 2 Teaspoons thyme leaves
  • 4 slices round white bread, such as Tuscan bread, toasted
  • 2 Teaspoons canola oil
  • 3 Ounces sliced or shaved Gruyère

Directions

Melt the butter over low heat in a large sauté pan, and then add the onions, trying to spread into 1 layer. Sprinkle generously with salt and a large pinch sugar. Sauté over very low heat until very tender and caramelized, about 25 minutes, stirring often to prevent burning.

Add the beef stock and thyme, increase the heat to medium, and cook until the beef broth is almost completely absorbed, but still a touch soupy.

Preheat the broiler and line a baking sheet with aluminum foil.

Brush 1 side of each bread slice with the canola oil, and season lightly with salt. Divide the Gruyère slices among the un-oiled sides of the bread. Top 2 of the slices with the onion mixture. Transfer the bread to a baking sheet, and broil until the cheese is melted, about 3 minutes. Top the onion slices with the plain cheesy slices and serve.

French Onion Soup Shopping Tip

Buy fresh herbs and spices to season your soup; fresh garlic, parsley, and thyme will enhance the flavor without being overpowering.

French Onion Soup Cooking Tip

Most soups are better the day after their made. If possible refrigerate your soup overnight before serving.
