Description
A comforting sandwich that combines the rich flavors of caramelized onions with gooey cheese, all nestled between crispy sourdough bread.
Ingredients
Scale
- 4 slices of sourdough bread
- 8 ounces of Gruyère cheese, grated
- 1 cup of caramelized onions (about 2 medium onions)
- 4 tablespoons of butter, softened
- 1 teaspoon of fresh thyme, chopped (or 1/2 teaspoon dried thyme)
- Black pepper, to taste
Instructions
- In a large skillet, melt 1 tablespoon of butter over medium heat. Add the sliced onions and cook, stirring occasionally, for about 20-30 minutes until they are soft and caramelized. Stir in the chopped thyme and season with salt and black pepper. Set aside.
- Spread 1 tablespoon of softened butter on one side of each of two slices of sourdough bread.
- On the unbuttered side of the two slices, layer half of the grated Gruyère cheese evenly. Top with half of the caramelized onions, then add the remaining Gruyère cheese on top. Place the other two slices of sourdough bread on top, buttered side facing out.
- Heat a skillet or griddle over medium heat. Carefully place the assembled sandwiches in the skillet. Cook for about 4-5 minutes on one side until golden brown and crispy. Flip the sandwiches and cook for another 4-5 minutes on the other side until golden brown and the cheese is melted.
Notes
- For gluten-free options, use gluten-free bread.
- Swap Gruyère cheese for Swiss or cheddar if preferred.
- Use vegan butter and cheese for a dairy-free version.
- Add herbs like thyme or rosemary for extra flavor.
- For a smoky flavor, consider adding a few slices of crispy bacon.
