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

Directions

Step 1

In a large skillet over medium heat, melt 2 tablespoons of butter.

Step 2

Add the sliced onions to the skillet and sprinkle with salt and sugar. Stir to combine.

Step 3

Cook the onions slowly, stirring occasionally, until they are deeply caramelized, about 25-30 minutes.

Step 4

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.

Step 5

Preheat a large non-stick skillet or griddle over medium-low heat.

Step 6

Spread the remaining 1 tablespoon of butter onto one side of each slice of bread.

Step 7

Place the buttered side of two slices of bread face down on the skillet.

Step 8

Evenly distribute the shredded Gruyère cheese over the bread slices in the skillet.

Step 9

Add a generous spoonful of the caramelized onions on top of the cheese.

Step 10

Place the remaining slices of bread on top, buttered side facing up, creating a sandwich.

Step 11

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.

Step 12

Remove the sandwiches from the skillet, let rest for 1-2 minutes, and slice in half before serving.
