Steps
1. Preheat oven to 200°C (390°F).
2. Heat olive oil in a nonstick pan over medium-low heat. Add onions and a pinch of salt, then cook, stirring occasionally, for 15 minutes until deeply golden and caramelized.
3. Roll out puff pastry on a lined baking sheet. Score a 1cm border around the edge without cutting through.
4. Spread caramelized onions evenly within the border. Dot crumbled goat cheese on top and sprinkle with thyme, pepper, and a little extra salt if desired.
5. Bake for 15–18 minutes, until pastry is puffed and golden.
6. Let cool slightly, cut, and serve warm.
