French onion grilled cheese is a delicious twist on the classic grilled cheese sandwich, featuring caramelized onions and melted cheese. To make this sandwich, you’ll need ingredients like onions, butter, bread, and cheese.
Start by thinly slicing onions and cooking them in butter over low heat until they are caramelized and golden brown. This process can take about 30-45 minutes, so be patient and stir the onions occasionally to prevent them from burning.
Once the onions are caramelized, remove them from the heat and set them aside. Butter one side of each slice of bread, then place a slice butter-side down in a skillet over medium heat.
Layer the bread with caramelized onions and your choice of cheese. Top with another slice of bread, butter-side up.
Cook the sandwich for a few minutes on each side, or until the bread is golden brown and the cheese is melted.
Serve the French onion grilled cheese hot, and enjoy the rich, savory flavors of caramelized onions and melted cheese!
Ingredients:
French Onion Grilled Cheese
- 4 tablespoons unsalted butter
- 1 pound yellow or Vidalia onions, peeled, halved and thinly sliced
- Kosher salt and black pepper
- 2 teaspoons sherry, red-wine or white-wine vinegar (optional)
- 4 ounces Gruyรจre cheese, grated
- 4 slices bread, cut no wider than 1/2-inch thick
Instructions:
In a large skillet over medium-high heat, melt 2 tablespoons butter. Add the onions and season with salt and pepper. Cover and cook, stirring once or twice, until the onions are softened, 3 to 5 minutes.
Uncover, reduce the heat to medium-low, and cook, stirring occasionally, until deep golden brown, 20 to 25 minutes.
If the onions look dry or like they might burn, add a few tablespoons of water at a time, scraping up any browned bits that are stuck to the bottom of the skillet.
If desired, once the onions are done, deglaze the skillet with vinegar and cook until the liquid has evaporated, about 1 minute. Transfer the onions to a medium bowl and season to taste with salt and pepper. Wipe out the skillet, or wash it, if necessary.
Add the cheese to the onions and stir to combine. Put down two slices of bread, and scoop half of the cheese-onion mixture onto each one. Top with the remaining slices of bread, and press down gently.
In the skillet, melt 1 tablespoon butter over medium heat. Add the sandwiches and cook until the bottoms turn golden brown, 3 to 4 minutes, reducing the heat to prevent toast from darkening too quickly, if needed. Add the remaining 1 tablespoon butter, flip the sandwiches, press down and cook until the cheese has fully melted and the bottoms turn golden brown, 3 to 4 minutes.
Serve immediately.
