Mushroom & Gruyère Puff Ingredients
• Here’s everything you need to create this delectable Mushroom & Gruyère Puff Pastry Braid.
For the Pastry
- Puff Pastry – Use cold pastry for easier handling and a flaky texture.
- Unsalted Butter – Adds a rich flavor; feel free to substitute with margarine if needed.
For the Filling
- Olive Oil – Provides moisture and depth; vegetable oil works as an alternative.
- Yellow Onion – Offers sweetness; shallots can be a lovely substitute.
- Garlic – Fresh garlic enhances flavor, but garlic powder is an acceptable backup.
- Cremini Mushrooms – The star of the filling packed with umami goodness; substitute with button mushrooms if you can’t find cremini.

- Salt and Black Pepper – Essential seasonings; adjust according to your taste preference.
- Dry White Wine – Optional but adds depth; swap in vegetable broth if you prefer.
- Cream Cheese – Key for creaminess and texture; ricotta or goat cheese can be good substitutes.

- Gruyère Cheese – The primary flavor profile with a nutty character; alternatives include Fontina or Swiss cheese.
- Dijon Mustard – Optional for a touch of tang; can be omitted or replaced with yellow mustard.
- Eggs – Acts as a binder and for the egg wash; use a flax egg for a vegan option.
- Fresh Parsley – For a bright garnish that adds color and freshness.
Step‑by‑Step Instructions for Mushroom & Gruyère Puff
Step 1: Preparation
Begin by preheating your oven to 350°F (180°C) and line a baking tray with parchment paper to prevent sticking. Ensure your puff pastry is cold, as this will help create that signature flaky texture. While the oven heats, gather all your ingredients for the Mushroom & Gruyère Puff to streamline your cooking process.
Step 2: Sauté Fillings
In a large skillet over medium heat, add the olive oil and unsalted butter. Once the butter has melted, add the diced yellow onion and sauté for about 5 minutes until softened and translucent. Then, add the minced garlic and sliced cremini mushrooms, cooking for an additional 8 minutes until the mushrooms are golden brown and tender, releasing their lovely earthy aroma.
Step 3: Seasoning
Stir in the fresh thyme, salt, and black pepper, followed by the dry white wine if you’re using it. Let this mixture cook for a couple of minutes until the wine has mostly evaporated, enhancing the flavors in your Mushroom & Gruyère Puff filling. Reduce the heat and let the mixture cool slightly before combining with the creamy components.
Step 4: Combine Filling
Remove the filling from heat and mix in the cream cheese and Parmesan until well combined and creamy. Allow the mixture to cool for a few minutes, then fold in the grated Gruyère cheese and one beaten egg to help bind your filling together. The blend should be rich and inviting, perfect for filling your puff pastry braid.
Step 5: Assemble Braid
Unroll your chilled puff pastry sheet onto a lightly floured surface and cut diagonal strips about 1 inch wide on each long side, leaving a central area untouched for the filling. Spoon the mushroom mixture down the center and carefully fold the ends over. Braid the cut strips over the filling, creating a beautiful, intricate design that showcases the filling.
Step 6: Bake
Transfer your assembled Mushroom & Gruyère Puff to the prepared baking tray and brush the top with the remaining beaten egg for a golden finish. Bake in the preheated oven for 20-22 minutes until the pastry is puffed up and a deep golden brown. The enticing aroma will surely fill your kitchen as it bakes!
Step 7: Cool and Serve
Once baked, remove the puff pastry braid from the oven and let it cool for about 10 minutes on a wire rack. This resting period allows the filling to set a bit, making slicing easier. Serve warm, and enjoy this delectable Mushroom & Gruyère Puff with friends or family, perhaps alongside a light salad or dipping sauce for a delightful brunch or appetizer.

Make Ahead Options
These Savory Mushroom & Gruyère Puff Pastry Braid are perfect for busy home cooks looking to save time during the week! You can prepare the filling up to 24 hours in advance; simply refrigerate it in an airtight container to maintain its freshness and prevent browning. Alternatively, you can assemble the entire braid a day ahead, covering it tightly and storing it in the refrigerator until you’re ready to bake. When it’s time to serve, take the braid out and let it sit at room temperature for about 15 minutes before brushing with egg wash and baking. This method ensures you can enjoy a delicious, flaky pastry without the last-minute rush!

Mushroom & Gruyère Puff Recipe FAQs
How do I choose the right mushrooms for this recipe?
Absolutely! I recommend using cremini mushrooms for their rich, earthy flavor, but if you can’t find them, button mushrooms make a great substitute. Look for mushrooms that are firm and free from dark spots or bruising for the best flavor and texture.
How can I store leftovers of the Mushroom & Gruyère Puff?
Very! You can store leftover Mushroom & Gruyère Puff at room temperature for up to 2 days, but for the best preservation, keep it in the refrigerator for up to 3 days. Wrap it tightly in plastic wrap to prevent it from drying out.
Can I freeze the Mushroom & Gruyère Puff before baking?
Absolutely! Wrap the unbaked braid tightly in plastic wrap and then foil to avoid freezer burn. It will last in the freezer for up to 2 months. When you’re ready to bake, just pop it in the oven directly from the freezer—add an extra 5-10 minutes to the baking time to ensure it cooks through.
What should I do if my pastry isn’t rising properly?
Don’t worry! If your pastry isn’t rising, it may be due to warm dough—keep your puff pastry cold while preparing it. Make sure your oven is fully preheated as well. If all else fails, a sprinkle of cold water over the dough before baking can sometimes help steam it further.
Is this Mushroom & Gruyère Puff suitable for vegetarians?
Yes! This recipe is vegetarian-friendly, but you should always ensure any cheese you use is free from animal rennet if you’re strictly vegetarian. Additionally, if you have lactose intolerance, consider substituting with vegan cheese alternatives for a dairy-free option.
Can I make the filling ahead of time?
Of course! You can prepare the filling up to 24 hours in advance. Just store it in an airtight container in the refrigerator. Allow it to cool completely before storing, then mix in the cheese and egg just before assembling the braid to maintain the best texture.
