Ingredients
- 1 sheet puff pastry (thawed)
- 2 large onions, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon butter
- 1 cup Gruyère cheese, grated
- 1 tablespoon fresh thyme leaves
- Salt and pepper to taste
- 1 egg (beaten, for egg wash)
Instructions
- Preheat your oven to 400°F (200°C).
- In a skillet, heat olive oil and butter over medium heat. Add sliced onions and cook for 20-25 minutes, stirring occasionally, until caramelized and golden brown. Season with salt, pepper, and thyme.
- Roll out the puff pastry on a floured surface to fit your tart pan. Transfer the pastry to the pan and prick the bottom with a fork to prevent puffing.
- Spread the caramelized onions evenly over the pastry, then sprinkle with grated Gruyère cheese.
- Brush the edges of the puff pastry with the beaten egg to create a golden finish.
- Bake for 25-30 minutes, or until the pastry is golden and the cheese is bubbling.
- Let the tart cool slightly before slicing and serving.
Notes
- Herb Variation: Add fresh rosemary or oregano to the onions for a unique herby flavor.
- Cheese Swap: If Gruyère isn’t available, use Swiss cheese or aged cheddar for a rich alternative
