Step‑by‑Step Instructions for Caramelized Onion & Thyme Pinwheels
Step 1: Caramelize Onions
In a large skillet, combine sliced yellow onions, olive oil, salt, and freshly ground black pepper. Cook over medium-low heat for 35-45 minutes, stirring frequently, until the onions turn a rich golden brown and have a jammy texture. If the onions stick to the pan, add a tablespoon of water to help deglaze. This step is crucial for developing the sweet flavor profile of the Caramelized Onion & Thyme Pinwheels.
Step 2: Cool Filling
Once the onions are beautifully caramelized, transfer them to a bowl to cool completely. This is important to prevent steam from making the puff pastry soggy later on. While the filling cools, the sweet and savory aromas will fill your kitchen, enticing everyone to gather around as they anticipate these delectable pinwheels.
Step 3: Prepare Puff Pastry
On a lightly floured surface, carefully unroll the chilled puff pastry. Use a rolling pin if necessary to smooth it out and ensure an even thickness. Spread the cooled caramelized onion mixture evenly across the pastry, leaving a half-inch border around the edges. This border will help seal the pinwheels when you roll them up, ensuring they hold their shape while baking.
Step 4: Roll and Cut
Sprinkle fresh thyme over the onion filling for an added burst of flavor. Starting from the long edge, roll the puff pastry tightly into a log. Once rolled, use a sharp knife to slice the log into ½-inch rounds. This will create your delightful Caramelized Onion & Thyme Pinwheels, ensuring each bite has a balanced filling encased in a flaky pastry.
Step 5: Bake
Preheat your oven to 400°F (200°C) while you arrange the sliced pinwheels on a parchment-lined baking sheet. Make sure to leave enough space between each pinwheel for even baking and air circulation. Bake for 18-22 minutes, or until the pinwheels are puffed up and golden brown. The delicious aroma will signal that they’re almost ready to serve!
Step 6: Serve
Once baked to perfection, remove the Caramelized Onion & Thyme Pinwheels from the oven and let them cool for a few minutes. Garnish with fresh thyme sprigs for an elegant touch. Serve them warm to your guests, who will appreciate the crispy texture and delicious flavor of these irresistible pinwheels that are perfect for any gathering.

Make Ahead Options
These Caramelized Onion & Thyme Pinwheels are perfect for meal prep, allowing you to enjoy a homemade appetizer with minimal effort! You can prepare the caramelized onion filling up to 3 days in advance and store it in the refrigerator. To maintain the quality and prevent sogginess, ensure it cools completely before storing it in an airtight container. When you’re ready to serve, just roll out your puff pastry, spread the cooled onion mixture, and slice it into pinwheels. Bake them fresh for 18-22 minutes until golden brown, and you’ll have delightful snacks that impress without the last-minute rush!
