Step‑by‑Step Instructions for Savory Mushroom & Gruyère Puff Pastry Braid
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (180°C). While the oven heats, prepare a baking tray by lining it with parchment paper to prevent sticking. It’s essential to have everything ready for your Savory Mushroom & Gruyère Puff Pastry Braid, as timing is key for that perfect crust.
Step 2: Sauté Aromatics
In a large skillet, heat a tablespoon of olive oil and a tablespoon of butter over medium heat until melted. Add the chopped onion and cook for about 5 minutes, stirring often, until they are translucent and fragrant. This will form the flavor base for your delicious filling, so make sure to keep an eye on it!
Step 3: Add Mushrooms and Garlic
Stir in the minced garlic and cremini mushrooms into the skillet, cooking for about 8 minutes. You’ll know they’re done when the mushrooms have browned and released their moisture. Keep stirring occasionally to ensure even cooking, allowing those wonderful earthy flavors to deepen, which is crucial for the Savory Mushroom & Gruyère Puff Pastry Braid.
Step 4: Season Filling
Once the mushrooms are cooked, add the thyme, salt, and pepper to taste. If you’re using white wine, pour it in now and cook until it mostly evaporates, about another 3 minutes. This step infuses the filling with delicious flavor, enhancing the overall taste of your braid!
Step 5: Incorporate Cheeses
Reduce the heat to low and mix in the cream cheese, Parmesan, and Dijon mustard, stirring until everything is melted and well combined. Finally, gently fold in the Gruyère cheese until it’s just melted. This rich and creamy filling is the heart of your Savory Mushroom & Gruyère Puff Pastry Braid!
Step 6: Bind Filling
Allow the filling to cool for a few minutes before adding one beaten egg to bind it all together. Stir until the egg is fully incorporated, creating a cohesive filling that will keep everything securely inside the puff pastry during baking.
Step 7: Prepare Pastry
On a lightly floured surface, unroll your chilled puff pastry. With a sharp knife, cut diagonal strips along the edges of the pastry, leaving the center intact for the filling. This will create a lovely braid effect that showcases your savory mushroom filling beautifully.
Step 8: Fill and Braid
Center your cooled filling over the untouched middle section of the pastry. Fold the edges over the filling, and then braid the diagonal strips across the top. Make sure to alternate sides to ensure the braid holds together, creating that stunning presentation for your Savory Mushroom & Gruyère Puff Pastry Braid.
Step 9: Glaze
In a small bowl, use a brush to apply an even layer of the remaining beaten egg over the braided pastry. This step is crucial for achieving that golden, glossy finish once baked. Make sure every exposed strip is coated for the best look!
Step 10: Bake
Carefully place your braided pastry in the preheated oven and bake for 20-22 minutes. Keep an eye on it, and look for a golden color and a puffy, flaky appearance. The aroma will fill your kitchen, signaling that your Savory Mushroom & Gruyère Puff Pastry Braid is almost ready!
Step 11: Rest
Once baked, remove the pastry from the oven and let it cool on the tray for about 10 minutes. This resting period helps set the filling and makes slicing easier. Your beautifully golden braid is now ready to be served, delighting your guests at brunch or on any occasion!

Make Ahead Options
These Savory Mushroom & Gruyère Puff Pastry Braids are perfect for busy weeknight meal preppers! You can prepare the filling up to 24 hours in advance by sautéing the mushrooms, onions, and spices as instructed, then storing the mixture in an airtight container in the refrigerator. To maintain quality, let the filling cool completely before sealing. When you’re ready to bake, unroll the chilled puff pastry and fill it with the prepared mixture, following the braiding steps as described. Brush with egg wash and bake directly from the fridge for a delightful treat that tastes just as fresh and satisfying as if made that day!

Expert Tips for Mushroom & Gruyère Puff Pastry Braid
-
Keep Pastry Cold: Make sure to keep the puff pastry chilled until it’s ready to use. This helps achieve maximum flakiness while baking.
-
Avoid Excess Moisture: Ensure the mushroom filling is well-cooked and not too wet. A soggy filling can lead to a disappointing, soggy crust.
-
Preheat Baking Tray: For extra crispiness, consider preheating your baking tray before placing the braid in the oven. It will help the bottom cook evenly.
-
Use Fresh Herbs: Fresh thyme will elevate the flavor of your filling. If using dried herbs, remember that dried is more concentrated—use less!

Don’t Skip the Glaze: Brushing the braided pastry with beaten egg gives it that lovely golden sheen. It adds to the visual appeal and enhances crunchiness.
-
Serve Warm: For the best experience, serve the Mushroom & Gruyère Puff Pastry Braid warm, allowing the delicious flavors to shine through.
How to Store and Freeze Mushroom & Gruyère Puff Pastry Braid
Fridge: Store leftovers wrapped tightly in foil or in an airtight container for up to 3 days. This will help maintain the flaky texture of your delicious Mushroom & Gruyère Puff Pastry Braid.
Freezer: Freeze the braid unbaked for up to 2 months by wrapping it well in plastic wrap and then in foil. When ready to bake, there’s no need to thaw; just pop it directly into a preheated oven.
Reheating: To reheat, place baked leftover pastry in a preheated oven at 350°F (175°C) for about 10-15 minutes until warmed through and crispy again. Avoid using the microwave to preserve texture.
Cooling: Make sure to allow your braid to cool completely before storing, as excess moisture can lead to sogginess in the pastry.

Mushroom & Gruyère Puff Pastry Braid Recipe FAQs
What type of mushrooms should I use?
Absolutely! Cremini mushrooms are fantastic for this recipe due to their earthy flavor; however, feel free to substitute with white button or shiitake mushrooms if that’s what you have on hand. For an adventurous twist, try a mix of shiitake and oyster mushrooms!
How should I store leftovers?
Leftovers of your Mushroom & Gruyère Puff Pastry Braid can be stored tightly wrapped in foil or placed in an airtight container for up to 3 days in the fridge. This will help retain that delightful flakiness.
Can I freeze this puff pastry braid?
Very! You can freeze the braided pastry unbaked for up to 2 months. Just wrap it well in plastic wrap and then in foil. When you’re ready to bake it, there’s no need to thaw—go ahead and place it in the preheated oven at 350°F (175°C) and bake until golden!
What if my filling turns out too wet?
If your filling is wet, ensure that you have cooked the mushrooms and garlic long enough to release excess moisture. You may also want to reduce the amount of cream cheese or cheese used. If it’s already too late, you can try whisking in a bit of cornstarch—start with 1 teaspoon—to help absorb some moisture.
Is this recipe suitable for vegetarians?
Yes! The Mushroom & Gruyère Puff Pastry Braid is not only vegetarian but can also be made vegetarian-friendly by using substitutes like margarine instead of butter and a flax egg in place of a regular egg for binding. It’s a delicious option for anyone looking for a savory, meatless dish.
How can I prevent the puff pastry from becoming soggy?
To prevent sogginess, ensure that your filling is not too wet and let it cool completely before assembling the braid. I also recommend using a preheated baking tray, which helps achieve that perfectly crispy bottom. Avoid microwaving leftovers, and opt to reheat in the oven for the best texture!
