Ingredients
Pastry
- 1 sheet puff pastry, thawed
Filling
- 2 large yellow onions, thinly sliced
- 2 tablespoons olive oil
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 tablespoon fresh thyme leaves, chopped
- Extra thyme sprigs for garnish
Instructions
- Prepare the onions: Heat the olive oil in a large skillet over medium heat. Add the thinly sliced onions, sprinkle with salt and pepper, and cook slowly, stirring occasionally, until the onions are golden and caramelized, approximately 25 to 30 minutes. Remove from heat and stir in the chopped fresh thyme leaves.
- Preheat the oven: Set your oven to 400 degrees Fahrenheit (200 degrees Celsius) to prepare for baking the pinwheels.
- Roll out the puff pastry: On a lightly floured surface, roll out the thawed puff pastry sheet into a rectangle about 12 by 10 inches, maintaining an even thickness.
- Add the filling: Evenly spread the caramelized onion and thyme mixture over the surface of the puff pastry, leaving a small border along the edges to prevent overflow during baking.
- Form the pinwheels: Starting from the long side, tightly roll the pastry into a log shape. Using a sharp knife, slice the log into 1-inch thick pinwheels.
- Bake the pinwheels: Place the pinwheels on a baking sheet lined with parchment paper, spacing them about 1 inch apart. Bake in the preheated oven for 15 to 20 minutes or until the pastry is puffed and golden brown.
- Garnish and serve: Remove from the oven, allow to cool slightly, then garnish with fresh thyme sprigs and serve warm or at room temperature.
Notes
- For extra flavor, you can add a sprinkle of grated Parmesan cheese to the filling before rolling.
- Make sure the puff pastry is thawed but still cold to prevent it from becoming sticky and hard to work with.
- If you prefer a milder onion taste, rinse the sliced onions briefly in cold water before caramelizing.
- Serve these pinwheels as an appetizer or a side dish with a fresh green salad for a light meal.
