Instructions
Instructions
- Melt 2 tablespoons of butter in a large skillet over medium-high heat. Add onions, season with salt and pepper, and cover. Cook until onions are softened, stirring occasionally, about 3 to 5 minutes.
- Uncover, reduce the heat to medium-low, and continue cooking, stirring occasionally, until deep golden brown, about 20 to 25 minutes.
- If desired, deglaze the skillet with vinegar and cook until the liquid has evaporated, about 1 minute. Set onions aside.
- Combine onions with grated Gruyère cheese. Assemble by scooping half the mixture onto two slices of bread. Top with remaining slices, and press gently.
- In the skillet, melt 1 tablespoon of butter over medium heat. Add sandwiches and cook until golden brown on bottoms, 3 to 4 minutes.
- Add remaining 1 tablespoon of butter, flip sandwiches, and press down. Cook until cheese is melted and bread is golden brown, another 3 to 4 minutes.
- Serve immediately.
Notes
For added flavor, use the vinegar while cooking. Enjoy the sandwich with your favorite side dish or dipping sauce.
