  • 4 cups Beef broth Chicken broth works in a pinch.
  • 1/2 cup White wine or brandy Optional, but recommended for flavor.
  • 4 slices Crusty bread Stale bread works best.
  • 2 cups Gruyère cheese Or Swiss if unavailable.
  • to taste Salt Adjust to your taste.

  • 1 teaspoon Fresh thyme Optional; dry thyme can be used.
  • 2 cloves Garlic Optional, for additional flavor.

Instructions
 

Preparation

  • In a heavy pot, melt the butter over medium heat.
  • Add the sliced onions and cook slowly, stirring occasionally, until they are super soft and brown, about 45 minutes.
  • Add the white wine or brandy, if using, and let it bubble up.
  • Pour in the beef broth and season with salt, pepper, and thyme. Simmer for about 10 minutes.

Toasting Bread

  • Toast the bread in the oven until golden and crispy.

Assembly & Broiling

  • Fill oven-safe bowls with soup, top each with a slice of toasted bread, and pile on the Gruyère cheese.
  • Broil in the oven until the cheese is golden and bubbly.

Notes

For best results, do not rush the onion-cooking time; let them caramelize properly. Store leftovers without cheese and bread to avoid sogginess.
