Caramelized Onion & Thyme Pinwheels Ingredients
For the Pinwheels
- Puff Pastry – Ensures that each bite is flaky and crispy; thaw properly to maintain the layers.
- Yellow Onions – The heart of this recipe; opt for large yellow onions for a sweeter flavor when caramelized.
- Olive Oil – Keeps the onions from sticking and enhances richness; always choose extra virgin for the best taste.
- Salt – Essential for flavor enhancement and helps draw out moisture from the onions during cooking.
- Black Pepper – Adds a touch of warmth without overshadowing the other flavors.
- Fresh Thyme – Offers a delightful freshness that complements the sweetness of the caramelized onion; fresh is key for optimal flavor.
Step‑by‑Step Instructions for Caramelized Onion & Thyme Pinwheels
Step 1: Prepare Onions
In a large skillet, heat 2 tablespoons of olive oil over medium-low heat. Add thinly sliced yellow onions, along with a generous pinch of salt and some freshly ground black pepper. Cook the onions slowly, stirring frequently, for about 35-45 minutes until they are deeply caramelized, golden brown, and reduced in volume. If they begin to stick, deglaze the pan with a splash of water to maintain that rich flavor.
Step 2: Cool Filling
Once the onions are caramelized to a sweet, jam-like texture, transfer them to a bowl and let them cool completely. This step is essential to stop the cooking process and prevent steam from ruining the pastry, which is crucial for achieving those perfect, flaky layers in your Caramelized Onion & Thyme Pinwheels.
Step 3: Prepare Oven & Pastry
While your filling cools, preheat your oven to 400°F (200°C). It’s time to roll out the thawed puff pastry! Place it on a lightly floured surface and gently roll it out to about a 1/8-inch thickness, ensuring it remains cool but pliable. This will give your pinwheels the perfect flaky texture once baked.
Step 4: Assemble Pinwheels
Spread the cooled caramelized onion mixture evenly across the rolled-out pastry, keeping a half-inch border around the edges. Sprinkle an ample amount of fresh thyme over the onion layer to complement its sweetness. Carefully roll the pastry tightly from the edge that has the filling, ensuring the edges remain secure and the filling stays inside.
Step 5: Slice & Bake
Using a sharp knife, cut the rolled pastry into ½-inch thick rounds, creating beautiful spirals of your Caramelized Onion & Thyme Pinwheels. Place them on a parchment-lined baking sheet, spacing them apart to allow for puffing. Bake in the preheated oven for 18-22 minutes, or until they are golden brown and puffed to perfection.
Step 6: Serving
Once baked, remove the pinwheels from the oven and transfer them to a serving platter. For an extra touch, garnish them with fresh thyme sprigs. These savory treats are best enjoyed warm, ready to impress your guests or your family with their delightful aroma and irresistible flavor!

How to Store and Freeze Caramelized Onion & Thyme Pinwheels
Fridge: Store leftover pinwheels in an airtight container for up to 4 days. This helps maintain their crispy texture while savoring the delicious onion flavor.
Freezer: Unbaked pinwheels can be frozen for up to 1 month. Place them on a baking sheet until firm, then transfer to a freezer bag. Bake from frozen, adding a few extra minutes to the time.
Reheating: For best results, reheat baked pinwheels in a 350°F (175°C) oven for about 10 minutes, just until heated through and crisp. Enjoy these delightful Caramelized Onion & Thyme Pinwheels fresh!
