Ingredients
- Sourdough or French bread
- 2 yellow or sweet onions, sliced
- 1 cup Gruyère cheese, shredded
- 1 cup provolone cheese, shredded
- 2 tbsp unsalted butter
- 1 tbsp olive oil
- 1/2 cup beef or vegetable broth
- Salt and pepper, to taste
- Optional: sugar, Dijon mustard, thyme, balsamic vinegar
Cooking Instructions
1. Caramelize Onions: In a large skillet, heat 2 tablespoons of unsalted butter and 1 tablespoon of olive oil over medium-low heat. Add the sliced onions and a pinch of salt. Cook the onions, stirring every few minutes, until they are golden brown and caramelized, about 25-30 minutes.
If desired, you can add a sprinkle of sugar to speed up the caramelization process.
2. Deglaze: Once the onions are caramelized, pour in the broth and add thyme if using. Stir to deglaze the pan, scraping up any browned bits. Cook for an additional 2-3 minutes until the liquid has reduced slightly. Remove from heat and set aside.
3. Prepare Bread: Generously butter one side of each slice of bread. If you like, spread Dijon mustard on the unbuttered side of the bread for added flavor.
4. Assemble Sandwich: On the unbuttered side of one slice, layer half of the Gruyère cheese, followed by the caramelized onions, and then the provolone cheese. Top with another slice of bread, buttered side out.
5. Grill Sandwich: Preheat a skillet over medium heat. Place the assembled sandwich in the skillet and cook for 3-4 minutes on each side, or until the bread is golden brown and the cheese is melted. Adjust the heat as necessary to avoid burning.
6. Serve: Once grilled to perfection, remove the sandwich from the skillet, slice it diagonally, and serve hot. Consider garnishing with fresh herbs for an extra touch.
For the best results, be sure to keep an eye on the onions while they caramelize; stirring occasionally is key to achieving that perfect golden-brown color without any burnt bits.
Experiment with different types of bread and cheese to find your ideal combination. Additionally, if you have any leftovers, they can be stored in an airtight container in the refrigerator for up to 2 days. Reheat them in the oven or skillet to keep that delightful crunch intact!
