Recipe Information
Ingredients
- 3 tablespoons unsalted butter
- 2 tablespoons olive oil
- 4 large yellow onions
- 0.5 teaspoon salt
- 1 teaspoon fresh thyme leaves
- 1 teaspoon granulated sugar
- 1 tablespoon balsamic vinegar
- 1 loaf baguette
- 1 cup Gruyère cheese
- 0.25 teaspoon freshly ground black pepper
Instructions
Peel and thinly slice the onions into uniform half-moons.
Heat a large skillet over medium-low heat and melt the butter with the olive oil.
Add the onions to the skillet and sprinkle with salt. Stir to coat the onions thoroughly in the butter-oil mixture.
Cook the onions for 25-30 minutes, stirring occasionally, until deep golden and caramelized. Reduce the heat if needed to prevent burning.
In the final minutes of cooking, stir in the thyme leaves, sugar, and balsamic vinegar. Cook for another 2-3 minutes until well combined. Remove from heat.
Preheat your oven to 375°F (190°C).
Slice the baguette diagonally into 1/2-inch thick slices. Arrange the slices on a baking sheet.
Toast the baguette slices in the preheated oven for 5 minutes, or until lightly crisped.
Remove the baking sheet from the oven and top each slice with a spoonful of caramelized onions, spreading it evenly.
Sprinkle grated Gruyère cheese generously over the onions on each toast.
Return the baking sheet to the oven and bake for 8-10 minutes, or until the cheese is melted and bubbly.
Remove from oven, sprinkle with freshly ground black pepper, and serve warm. Enjoy!
