Ingredients
- 1 sheet puff pastry, thawed
- 3 medium yellow onions, sliced
- 1 cup Gruyere cheese, shredded
- 2 tablespoons olive oil
- Salt to taste
- Black pepper to taste
Instructions
- Preheat and Prepare Onions: Preheat your oven to 400°F (205°C). Meanwhile, peel and thinly slice the three medium yellow onions to ensure even caramelization.
- Caramelize Onions: Heat two tablespoons of olive oil in a skillet over medium heat. Add the sliced onions along with a pinch of salt to help draw out moisture. Cook, stirring frequently, until the onions turn golden brown and caramelized, approximately 15-20 minutes.
- Assemble Tart: On a lightly floured surface, roll out the thawed puff pastry sheet to fit your baking tray. Spread the caramelized onions evenly over the pastry, then top with one cup of shredded Gruyere cheese. Season with freshly ground black pepper to taste.
- Bake the Tart: Place the assembled tart in the preheated oven. Bake for 25-30 minutes or until the puff pastry is golden, puffed, and crisp, and the cheese is melted and slightly browned.
Notes
- For extra flavor, you can add a sprinkle of fresh thyme or rosemary before baking.
- Serve warm with a green salad for a complete meal.
- The tart can be prepared in advance and baked just before serving.
- Ensure the puff pastry is fully thawed before use to prevent tearing.
- Use a sharp knife to slice the onions thinly for even cooking.
