Total Time:50 minutes
Yield:12 pinwheels
Ingredients
Pinwheel 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, plus extra sprigs for garnish
Dough
1 sheet puff pastry, thawed
Instructions
Prepare the onions: Heat the olive oil in a large skillet over medium-low heat. Add the thinly sliced onions, salt, and black pepper, stirring gently to coat. Cook the onions slowly, stirring occasionally, for about 30 minutes until deeply caramelized and golden brown.
Incorporate thyme: Stir the chopped fresh thyme leaves into the caramelized onions and cook for an additional 1-2 minutes to release their aroma. Remove the pan from heat and let the mixture cool slightly.
Roll out the puff pastry: On a lightly floured surface, roll the thawed puff pastry sheet into a rectangle roughly 12 by 10 inches. Spread the cooled onion and thyme mixture evenly over the pastry, leaving a small border around the edges.
Form the pinwheels: Starting from one long edge, carefully roll the dough into a tight log. Use a sharp knife to slice the log into 1-inch thick pinwheels.
Bake: Place the pinwheels on a parchment-lined baking sheet with space between each. Bake in a preheated oven at 400 degrees Fahrenheit (200 degrees Celsius) for 15-20 minutes or until puffed and golden brown.
Serve: Let the pinwheels cool slightly before garnishing with extra thyme sprigs. Serve warm or at room temperature as a delightful appetizer or snack.
Notes
To ensure even caramelization, cook the onions slowly over low heat and avoid stirring too frequently.
For a vegan option, confirm the puff pastry is vegan-friendly or make your own pastry dough.
Pinwheels taste great freshly baked but can be stored in an airtight container for up to two days and reheated in the oven for crispness.
If you prefer a stronger thyme flavor, increase the fresh thyme to 1 1/2 tablespoons.
