Warm Onion Tart with Thyme
['1 Spanish onion', '1 tablespoon unsalted butter', '1 tablespoon fresh thyme leaves', 'Salt and freshly ground black pepper', '1 sheet frozen puff pastry', 'thawed according to package directions']

Peel and cut the onion in half through the root. Trim the ends and then julienne the onion lengthwise.
Melt the butter in a small sauté pan over medium heat. Add the onion and thyme and cook, stirring occasionally, for 10 to 15minutes or until the onion is a deep golden brown. Season to taste with salt and pepper. Keep warm until ready to serve.
Meanwhile, preheat the oven to 400°F.

Unfold the puff pastry sheet on a lightly floured work surface and turn over to prevent the creases from splitting. Pat down gently to flatten the sheet.
Using a 1-inch round fluted cookie cutter, stamp out 6 rounds and transfer to an ungreased baking sheet. Bake for 8 to 10minutes or until puffed and golden brown.
