Herbed Mushroom & Gruyère Pastry Plait
Mediterranean Herbed Mushroom & Gruyère Pastry Plait is a beautiful, savory centerpiece that feels special without being complicated. Flaky pastry is wrapped around a rich filling of sautéed mushrooms, garlic, herbs, and nutty Gruyère cheese, then braided into an elegant plait before baking until golden. The mushrooms bring depth and earthiness, the cheese adds creaminess and structure, and the herbs tie everything together with classic Mediterranean warmth. This dish works equally well as a vegetarian main, a brunch showstopper, or a dinner party appetizer sliced into generous portions. It looks impressive on the table, yet relies on simple ingredients and straightforward steps.
Prep time: 25 minutes
Cook time: 35 minutes
Total time: 1 hour
Serves: 4 to 6
Ingredients
For the Filling
2 tablespoons extra virgin olive oil
1 tablespoon unsalted butter
12 ounces mushrooms, finely chopped (cremini or mixed mushrooms)
1 small onion or 2 shallots, finely diced
3 garlic cloves, minced
1 teaspoon dried thyme
½ teaspoon dried oregano
Salt and black pepper to taste
1 tablespoon fresh parsley, chopped
For the Pastry
1 sheet puff pastry, thawed
1½ cups grated Gruyère cheese
1 egg, beaten
1 teaspoon water
For Finishing
Sesame seeds or poppy seeds, optional
Extra fresh herbs for garnish
Instructions
Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper and set aside.
Heat olive oil and butter together in a large skillet over medium heat. Add the chopped mushrooms and spread them into an even layer.
Let the mushrooms cook undisturbed for 4 to 5 minutes until they begin to brown and release moisture. Stir and continue cooking until most liquid has evaporated.
Add the onion or shallots and cook for 3 to 4 minutes until softened and lightly golden.
Stir in the garlic, thyme, oregano, salt, and black pepper. Cook for 30 seconds until fragrant, then remove from heat.
Stir in the fresh parsley and allow the mixture to cool completely. Cooling is important so the pastry stays flaky.
Roll out the puff pastry slightly on a floured surface and transfer it to the prepared baking sheet. Place the mushroom mixture down the center lengthwise, leaving space on both sides.
Sprinkle the grated Gruyère evenly over the mushroom filling. Cut diagonal strips along both sides of the pastry, then fold them alternately over the filling to form a plait.
Whisk together the egg and water. Brush the pastry generously with egg wash and sprinkle with seeds if using.
Bake for 30 to 35 minutes until deeply golden and puffed. Let rest for 5 minutes before slicing and serving.
Tips
Finely chopping mushrooms helps them cook evenly and prevents bulky filling.
Let mushrooms brown before stirring to develop flavor.
Always cool the filling before assembling the pastry.
Use parchment paper to prevent sticking.
Grate cheese fresh for better melting.
Don’t overfill the pastry or it may burst.
Trim uneven pastry edges for a neater plait.
Egg wash gives a glossy, bakery style finish.
Let the pastry rest before slicing for clean cuts.
Serve warm, not piping hot, for best texture.
Variations
Add sautéed spinach to the mushroom mixture.
Swap Gruyère for fontina or aged cheddar.
Add a splash of white wine to mushrooms for depth.
Use rosemary instead of thyme for a bolder herb note.
Add caramelized onions for sweetness.
Sprinkle crushed walnuts or pine nuts into the filling.
Use phyllo dough for a lighter, crispier version.
Add sun dried tomatoes for Mediterranean tang.
Make mini plaits for individual servings.
Add a touch of Dijon mustard under the filling.
