Ingredients

To make these delicious Caramelized Onion & Gruyère Tartlets, gather the following ingredients:

• 1 sheet of puff pastry, thawed
• 2 large onions, thinly sliced
• 2 tablespoons of olive oil
• 1 tablespoon of butter
• 1 tablespoon of balsamic vinegar
• Salt and pepper to taste
• 1 cup of Gruyère cheese, grated

Instructions

Creating these tartlets is a straightforward process, and here’s how you can do it:

1. Preheat your oven to 400°F (200°C).

3. Stir in the balsamic vinegar and season with salt and pepper. Cook for another 2 minutes, then remove from heat and let cool slightly.

5. Top each pastry circle with a spoonful of caramelized onions and a sprinkle of grated Gruyère cheese.
6. Bake in the preheated oven for 15-20 minutes, or until the pastry is golden and the cheese is bubbly.
