Preheat your oven to 200°C (392°F).
Roll out the puff pastry sheet on a lightly floured surface and set aside.
In a pan, melt the butter over medium heat.
Add the chopped onion and sauté until translucent.
Add the sliced mushrooms and thyme, and cook until the mushrooms are soft and any liquid has evaporated.
Remove the pan from heat and let the mixture cool slightly.
Grate the cheddar cheese and mix it with the mushroom and onion mixture.
Spread the mushroom and cheese mixture evenly over the puff pastry, leaving a small border around the edges.
Fold the edges of the pastry over the filling to create a border.
Transfer the pastry to a baking sheet lined with parchment paper.
Bake in the preheated oven for 20-25 minutes, or until the pastry is golden brown and puffed.
Remove from the oven and let it cool slightly before serving.
