Ingredients
- 4 tablespoons Unsalted butter
- 2 large Yellow onions
- 3 sprigs Fresh thyme
- 0.5 teaspoons Salt
- 0.25 teaspoons Black pepper
- 0.5 teaspoons Sugar
- 0.25 cups Dry white wine
- 8 ounces Gruyère cheese
- 8 slices Bread, thick slices (sourdough or rustic loaf)
- 2 tablespoons Olive oil
Directions
Step 1
Peel and thinly slice the yellow onions.
Step 2
In a large skillet over medium heat, melt 2 tablespoons of butter and the olive oil. Add the sliced onions, thyme sprigs, salt, black pepper, and sugar.
Step 3
Cook the onions for about 25-30 minutes, stirring frequently, until deeply caramelized and golden brown. Adjust heat as necessary to avoid burning.
Step 4
Once caramelized, remove and discard the thyme sprigs. Add the white wine to the skillet, scraping the bottom of the pan to deglaze. Cook until the wine has evaporated, about 2-3 minutes. Remove onions from heat and set aside.
Step 5
Grate the Gruyère cheese and divide it evenly among 4 slices of bread. Top the cheese with the caramelized onions, then place the remaining bread slices on top to form sandwiches.
Step 6
Heat a large skillet or griddle over medium heat. Add 1 tablespoon of butter to the pan and let it melt.
Step 7
Place the sandwiches in the skillet (work in batches if necessary) and cook for 3-4 minutes per side, pressing gently with a spatula, until the bread is golden and the cheese is melted. Add the remaining butter to the skillet as needed when flipping sides.
Step 8
Once all sandwiches are toasted and melted, remove them from the skillet and let them rest briefly. Slice in half and serve immediately.
