- 2 1/2 tablespoons butter
- 2 large onions, thinly sliced
- Pinch of thyme
- 3/4 cup water (divided)

Instructions
Step 1: Prepare the Caramelized Onions
- Melt Butter:

- Add Onions:
- Add the thinly sliced onions to the skillet. Cook, stirring occasionally, until the onions are soft and golden brown, about 20-25 minutes.
- Add Seasoning:
- Stir in a pinch of thyme and 1/4 cup of water. Continue to cook until the water evaporates and the onions are deeply caramelized.
- Add Brandy or Sherry (Optional):
- If using, add the brandy or sherry and cook for another 2 minutes, allowing the alcohol to evaporate. Remove the onions from the skillet and set aside.

Step 3: Cook the Burger Patties
- Preheat Grill or Skillet:
- Preheat your grill to medium-high heat or heat a large skillet over medium-high heat.
- Cook Patties:
- Place the patties on the grill or skillet and cook for about 4-5 minutes per side, or until the internal temperature reaches 160°F (71°C).
Step 4: Add Cheese
- Top with Cheese:
- During the last minute of cooking, place a slice of Gruyere or Provolone cheese on each patty. Cover the grill or skillet to melt the cheese.
Step 5: Toast the Buns
- Toast Buns:
