Step‑by‑Step Instructions
  1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
  2. Unfold the thawed puff pastry on a floured surface, roll it out to a rectangle, and score a one-inch border around the edges.
  3. Melt unsalted butter in a skillet over medium heat, add onions, salt, and sugar, then cook for 20-25 minutes until caramelized.
  4. Spoon the caramelized onions over the puff pastry, layer the sliced apples, and sprinkle cheddar cheese and thyme on top.
  5. Beat an egg and brush it over the pastry edges for a golden finish. Optionally drizzle honey over the apple layer.
  6. Bake in the preheated oven for 20-25 minutes until the pastry is golden and cheese is melted.
  7. Remove from the oven and let cool for about 5 minutes before slicing and serving.
