Step-by-Step Instructions
Preparing the Mushroom Filling
Start by carefully cleaning the mushrooms by wiping them with a damp cloth to remove any trace of dirt. Avoid washing them directly under water, as they would absorb too much moisture and could make the pastry soggy. Slice them finely into even pieces about 1/8 inch (2-3 mm) thick. In a large skillet, heat the olive oil and butter over medium-high heat. Add the finely chopped shallots and sweat them for 2-3 minutes until they become translucent. Incorporate the minced garlic and cook for an additional 30 seconds, just enough to release its aroma without letting it brown. Increase the heat and add the mushrooms in a single layer. Let them brown without stirring for 1-2 minutes, then stir and continue cooking for about 5 minutes until all the water has evaporated and the mushrooms are nicely golden. Season generously with salt, pepper, and fresh thyme leaves. Remove from heat, incorporate the crème fraîche, and mix well. Allow the mixture to cool completely before using it to fill the pastry, as a hot filling would melt the butter in the puff pastry and compromise its layering.
Preparing the Swirls
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. Unroll the puff pastry on a lightly floured surface and gently spread it to form a regular rectangle. Using a spatula or the back of a spoon, evenly distribute the cooled mushroom mixture over the entire surface of the pastry, leaving a border of about 1/2 inch (1 cm) on one of the long sides. Sprinkle the grated cheese over the mushrooms and scatter with chopped parsley. Starting from the long side opposite to the edge left free, firmly roll the pastry onto itself to form a long log. Be careful not to roll too tightly to allow the pastry to rise during baking. Lightly brush the free edge with a little water or beaten egg yolk before finishing the roll to properly seal the junction. Place the resulting roll in the refrigerator for about 15-20 minutes to firm up, which will greatly facilitate cutting.
Cutting and Baking
Remove the pastry roll from the refrigerator and, using a sharp knife or a cutting wire (like for cheese), slice it into sections about 1/2 to 3/4 inch (1.5 to 2 cm) thick. Be sure to exert clean vertical pressure to avoid crushing the pastry and preserve the circular shape. Arrange the swirls on the prepared baking sheet, spacing them at least 1 inch (3 cm) apart, as they will spread during baking. In a small bowl, beat the egg yolk with a teaspoon of water and gently brush the tops of the swirls to achieve a perfect golden finish. Bake in the middle of the preheated oven and cook for 15-18 minutes, until the swirls are well puffed and golden. Watch the baking carefully as the time may vary depending on your oven. The swirls should have a beautiful uniform golden color and be completely cooked in the center. Once baked, remove them from the oven and let them rest on the baking sheet for 5 minutes before transferring them to a wire rack to prevent the bottom from becoming soggy.
Serving and Presentation
Serve these swirls ideally warm, when their contrast of textures is at its peak. Arrange them harmoniously on a white serving dish or a light wooden board to highlight their beautiful golden coloration. Sprinkle them with finely chopped fresh parsley just before serving to add a touch of vibrant color. For an even more elegant presentation, you can place a few sprigs of fresh thyme around the swirls and possibly add a small bowl of lightly seasoned crème fraîche or a richer mushroom sauce for those who wish to intensify the taste experience. These swirls can be perfectly enjoyed by hand, making them an ideal appetizer for receptions, but they can also be served with cutlery as a more formal side dish.

Pro Tips
- Work with cold but not too cold puff pastry so it remains malleable
- Make sure the mushroom filling is completely cooled before spreading it
- For cleaner spirals, refrigerate the roll for 30 minutes before cutting it
- Use a serrated knife or cutting wire to slice without crushing the swirls
- Brush the top with a little melted butter right after baking for more shine
Storage Tips
These Mushroom Puff Pastry Swirls are at their taste peak when freshly baked, but they can be prepared in advance in several ways. For advance preparation, you can prepare the mushroom filling up to two days ahead and store it in the refrigerator in an airtight container. The swirls can be assembled and cut, then stored raw in the refrigerator overnight, covered with non-airtight plastic wrap to prevent the pastry from becoming moist.
If you wish to pre-bake them, do so for only about 12 minutes, then let them cool completely before storing them in an airtight container at room temperature for a day. To serve, reheat them in a preheated oven at 350°F (180°C) for 3-5 minutes to restore their crispiness.
For longer storage, unbaked swirls can be frozen. Place them on a tray well-spaced apart, freeze them until solid, then transfer them to a freezer bag where they will keep for up to a month. To bake from frozen, simply add 3-5 minutes to the normal cooking time, watching carefully to prevent them from burning.
Customization Ideas
The beauty of this recipe lies in its versatility and the many possible variations. For a more luxurious version, incorporate some wild mushrooms like chanterelles or porcini into your mixture, or add a small amount of rehydrated and finely chopped dried mushrooms to intensify the flavor.
Cheese lovers will appreciate the addition of crumbled blue cheese or fresh goat cheese between the mushrooms before rolling the pastry. For a more herbaceous note, experiment with different herbs such as sage, rosemary, or finely chopped tarragon.
A heartier version can include pieces of prosciutto or bacon previously browned with the mushrooms. For a vegan option, replace the butter with olive oil, use vegan puff pastry, and replace the cream with a plant-based alternative.
For an additional texture contrast, add pine nuts or hazelnuts, crushed and lightly toasted, to the filling. Gourmets can also incorporate a thin layer of tapenade or pesto before spreading the mushrooms, thus adding an extra dimension of flavor.
Finally, these swirls lend themselves perfectly to miniaturization for even more elegant cocktail bites: simply cut pastry circles, place a small amount of filling on them, and fold them into half-moons before glazing and baking them.
Special Technique: The Art of Perfect Puff Pastry
The success of these swirls largely depends on achieving impeccable, airy, and crispy puff pastry. This technique, prized by professional pastry chefs, requires particular attention to several key factors often overlooked.
It all starts with temperature: the puff pastry should be cold but not frozen, ideally around 50°F (10°C). Too cold, it will break; too warm, the butter it contains will begin to melt, compromising the formation of layers. If you’re working in a hot kitchen, cool your work surface by placing a tray with ice on it for a few minutes before wiping it dry and rolling out your pastry.
The thickness of the filling is also crucial: it should be uniform and relatively thin (about 1/8-1/6 inch or 3-4 mm) to allow for tight rolling without excess material that would create moist areas. The filling must be completely cooled and relatively dry – any excess moisture is the enemy of puff pastry.
The rolling technique deserves special attention: start from the longest side, maintaining constant but gentle tension. The common mistake is to roll too tightly, which compresses the layers of pastry and hinders their development during baking. Imagine that you are gently rolling a precious parchment, with firmness but respect.
Cold resting is a step often rushed: after rolling, the pastry cylinder must rest in the refrigerator for at least 30 minutes, ideally on a flat surface to avoid any deformation. This time allows the pastry to relax and the butter to stabilize at the ideal temperature.
Finally, cutting must be done with a clean and vertical gesture, without a sawing motion that would crush the edges. The ideal is to use a thin-bladed knife previously dipped in hot water and wiped dry, or better yet, a cutting wire stretched between your hands. This technique preserves the spiral structure so characteristic of these delicious swirls.
Frequently Asked Questions
Can I use ready-made puff pastry?
Absolutely! Store-bought puff pastry gives excellent results. Preferably choose an all-butter version for optimal taste.
How can I prevent my swirls from becoming soggy?
Make sure the mushrooms are well sautéed until complete evaporation of their water, and that the filling is completely cooled before spreading it on the pastry.
What if I don’t have crème fraîche?
You can replace it with mascarpone, drained ricotta, or even a thick béchamel sauce. For a lighter version, use cream cheese.
My swirls deformed during baking, what happened?
Several possible reasons: the pastry was too warm before baking, the oven wasn’t hot enough when placing them in, or the spirals weren’t tight enough when cutting.
Can I prepare these swirls without dairy products?
Yes, use vegan puff pastry, replace the butter with olive oil, and the cream with a plant-based alternative. Omit the cheese or use a plant-based version that melts well.
