Recipe Information
Ingredients
- 3 tablespoons Unsalted butter
- 3 Yellow onions, thinly sliced
- 0.5 teaspoon Salt
- 0.5 teaspoon Sugar
- 0.25 cup Beef broth
- 1 teaspoon Fresh thyme leaves
- 4 Thick slices of artisan bread
- 1.5 cups Gruyère cheese, shredded
- 1 tablespoon Olive oil
Instructions
In a large skillet over medium heat, melt 2 tablespoons of butter.
Add the sliced onions to the skillet and sprinkle with salt and sugar. Stir to combine.
Cook the onions slowly, stirring occasionally, until they are deeply caramelized, about 25-30 minutes.
Add the beef broth and thyme leaves to the skillet. Stir to deglaze the pan and cook for another 2-3 minutes, until the liquid is mostly absorbed. Remove from heat and set aside.
Preheat a large non-stick skillet or griddle over medium-low heat.
Spread the remaining 1 tablespoon of butter onto one side of each slice of bread.
Place the buttered side of two slices of bread face down on the skillet.
Evenly distribute the shredded Gruyère cheese over the bread slices in the skillet.
Add a generous spoonful of the caramelized onions on top of the cheese.
Place the remaining slices of bread on top, buttered side facing up, creating a sandwich.
Cook the sandwiches over medium-low heat for 3-4 minutes on each side, or until the bread is golden brown and crispy and the cheese is melted.
Remove the sandwiches from the skillet, let rest for 1-2 minutes, and slice in half before serving.
