The pastry starts to puff at the edges first, and the little spirals turn golden while the tree takes shape on the baking sheet. I learned not to rush the slicing: if the logs are still soft, the rounds can flatten before they ever reach the oven. These pinwheel Christmas tree appetizers keep the familiar pesto-and-cheese filling tucked into flaky pastry, with the slices arranged into a shareable centerpiece.
Each sheet gets its own layer of basil pesto, mozzarella, and Parmesan before it’s rolled into a log. A short chill firms the pastry enough to cut neat rounds without squeezing out the filling. Leave a small gap between the slices as you arrange the tree; the pastry needs room to puff, but the pieces still bake into one connected shape. The result is crisp, golden edges around warm, savory centers.
Kitchen Note
Brush the egg wash over the exposed pastry, not over the cheesy centers. That gives the pastry a glossy golden finish without brushing the filling around.
Save this Pinwheel Christmas Tree Appetizer for a flaky pesto-and-cheese centerpiece with golden, pull-apart edges.
Why the Small Gaps Between Pinwheels Make a Better Tree
These rounds need a little breathing room. Puff pastry expands in the oven, and slices placed tightly together can press into one another before their edges have a chance to turn crisp. Leave about 1/4 inch between them, and the tree keeps its outline while each pinwheel still has space to puff.
On the other hand, setting the slices too far apart can make the finished tree look disconnected. The close rows let the edges meet as the pastry bakes, so you can lift and serve the appetizer as a connected shape. Center each row as you build it: one slice at the top, then rows of two, three, four, five, and six. The three remaining slices make a short trunk beneath the widest row. It doesn’t need to look ruler-straight; an even arrangement gives you a recognizable tree and helps the pieces bake at a similar pace.
Think of the spacing as a practical part of the shape, not decoration. The tree is assembled from individual pinwheels, so a slight gap lets the pastry do its expanding without losing the outline you’ve made.
What the Cold Pastry and Two Cheeses Bring to Each Pinwheel
- Frozen puff pastry — Thaw it according to the package directions, then keep it cold. Chilled pastry is easier to roll, firm up, and slice; if it gets warm and floppy, the rounds are harder to handle. The package brand matters less than having pastry that’s properly thawed but still cold.
- Basil pesto — Pesto supplies the concentrated basil flavor and spreads easily across the pastry. Choose a basil pesto whose flavor you enjoy, since it’s the main savory seasoning in the filling. A different brand of basil pesto works in the same quantity, though its saltiness and garlic or basil intensity may vary.
- Mozzarella — Shredded mozzarella gives the filling its soft, stretchy cheese layer. A standard bag of shredded mozzarella is convenient here; the important detail is distributing it across the pesto rather than leaving a thick mound down the center, which makes the logs harder to roll tightly.
- Finely grated Parmesan — The fine shreds spread through the filling more evenly than large flakes and add a sharper, saltier note alongside the mild mozzarella. Use finely grated Parmesan so it doesn’t form bulky pockets when you roll the pastry.
- Egg and water — Beating them together makes a simple wash that helps the exposed pastry bake up with an even golden sheen. Beat until the yolk and white are combined, then brush a light coat onto the visible pastry before baking.
From Two Filled Logs to a Golden Pull-Apart Tree
Get the oven and baking sheet ready
Heat the oven to 400°F and line an 18×13-inch rimmed baking sheet with parchment paper. Having the pan ready before you start assembling keeps the filled pastry from sitting out while you look for a place to arrange it. Work with one pastry sheet at a time and leave the second sheet cold until you’re ready for it. The parchment also makes it easier to serve the baked tree from the pan.
Fill each sheet and roll it into a log
Spread 1/4 cup of basil pesto over each pastry sheet, then sprinkle each with 3/4 cup mozzarella and 2 tablespoons Parmesan. Spread the filling across the sheet so the cheese isn’t concentrated in one heavy strip. Roll each sheet tightly into a log, keeping the filling tucked inside as you go. A snug roll gives you defined spirals when you slice.
Chill, slice, and arrange the tree
Set the logs seam-side down in the refrigerator for 15 minutes, until they feel firm enough to slice cleanly. Cut each log into 12 slices about 3/4 inch thick. Arrange 21 slices in centered rows of one through six, then set the remaining three in a row beneath the widest row for the trunk, leaving about 1/4 inch between slices. If a round shifts while you’re arranging the tree, nudge it back into position before brushing on the egg wash.
Brush, bake, and let the pastry settle
Beat the egg with the water and brush it over the exposed pastry. Bake for 20–25 minutes, until the pastry is puffed and deep golden brown; pale pastry needs more time to develop crisp edges. Let the tree rest on the baking sheet for 5 minutes before serving. That brief pause gives the hot cheese and pastry a moment to settle, so the pinwheels are easier to lift.
Three Ways to Change the Shape or Make a Gluten-Free Version
Serve the pinwheels as individual rounds
Keep the same pesto-and-cheese filling, but arrange the 24 slices as individual pinwheels instead of building the tree. Leave about 1/4 inch between them on the parchment-lined sheet. You’ll get more crisp edges and a platter-style appetizer rather than a connected centerpiece.
Arrange the slices as a wreath
For a different centerpiece, arrange the same filled pinwheels in a loose ring instead of rows, keeping a small gap between slices so the pastry has room to expand. The flavor stays the same, while the open center gives the appetizer a wreath shape. Bake until the pastry is puffed and deep golden.
Use gluten-free puff pastry
Replace the regular puff pastry with two sheets of gluten-free puff pastry, thawed according to its package directions and kept cold. Gluten-free pastry can be more delicate to roll and slice, so handle the logs gently and let them firm in the refrigerator before cutting. The spirals may be less lofty, but the pesto and cheese filling stays the same.
Storage and Reheating
- Refrigerator: Store leftovers in an airtight container for up to 3 days. The pastry will soften as it sits.
- Freezer: Freeze baked, cooled pinwheels in a freezer-safe container for up to 1 month. They’ll be less crisp after thawing than freshly baked.
- Reheating: Warm refrigerated or thawed pieces on a baking sheet at 350°F for about 8–10 minutes, until hot and crisp. The microwave heats them quickly but leaves the pastry soft.
