There’s something deeply satisfying about pulling a golden, flaky pastry from the oven, especially when you’ve created its beautiful braided shape yourself. This Herbed Mushroom & Gruyère Pastry Plait is that perfect centerpiece—visually stunning yet deceptively simple to make. It combines meaty, umami-rich mushrooms sautéed with garlic, thyme, and a splash of white wine, all enveloped in a blanket of rich, melting Gruyère cheese. Wrapped in crisp, buttery puff pastry, it’s a vegetarian dish that feels indulgent and special, ideal for a weekend brunch, a light lunch with a salad, or as the star of your holiday appetizer spread.
Ingredients
1 tbsp olive oil
1 tbsp unsalted butter
1 medium yellow onion, finely diced
2 cloves garlic, minced
450g (1 lb) mixed mushrooms (cremini, shiitake, oyster), cleaned and sliced
2 tsp fresh thyme leaves (or ¾ tsp dried)
2 tbsp dry white wine (or vegetable broth)
120g (4 oz) cream cheese, at room temperature
60g (½ cup) finely grated Parmesan cheese
Salt and freshly ground black pepper, to taste
1 sheet (approx. 250g) frozen all-butter puff pastry, thawed in the fridge overnight
120g (4 oz) Gruyère cheese, coarsely grated
1 large egg, beaten (for egg wash)
2 tbsp sesame seeds or poppy seeds (optional)
Fresh parsley, chopped, for garnish
Step-by-Step Instructions
Step 1: Prepare the Filling
In a large skillet over medium heat, melt the butter with the olive oil. Add the diced onion and cook for 4-5 minutes until soft and translucent. Add the minced garlic and cook for another minute until fragrant.
Increase the heat to medium-high and add all the sliced mushrooms. Avoid crowding; cook in two batches if your pan is small. Sauté for 8-10 minutes, stirring occasionally, until the mushrooms have released their liquid and it has mostly evaporated, and they are beautifully browned.
Stir in the fresh thyme and cook for 30 seconds. Pour in the white wine to deglaze the pan, scraping up any browned bits from the bottom. Allow the wine to bubble and evaporate completely, about 1-2 minutes.
Remove the skillet from the heat. Stir in the cream cheese and grated Parmesan until smoothly incorporated. Season generously with salt and pepper. Taste and adjust seasoning. Transfer the mixture to a bowl and let it cool completely to room temperature. (This is crucial to prevent a soggy pastry.)
Step 2: Assemble the Plait
Line a large baking sheet with parchment paper. On a lightly floured surface, roll the thawed puff pastry sheet into a rectangle roughly 25cm x 35cm (10″ x 14″). Transfer the pastry rectangle to the prepared baking sheet.
Using a sharp knife or pizza cutter, make diagonal cuts (about 3cm/1.25″ apart) down each long side of the pastry rectangle, leaving a 5-7cm (2-3″) wide uncut strip down the center. This will create “strands” to plait over the filling.
Spread the cooled mushroom mixture evenly down the center uncut strip. Sprinkle the grated Gruyère cheese evenly over the mushrooms.
Step 3: Braid the Pastry
Begin the plait by folding the top and bottom flaps of the center strip over the ends of the filling to seal it in. Then, take the top left pastry strand and fold it diagonally across the filling to the opposite side. Repeat with the top right strand, crossing it over to the left. Continue this left-over-right pattern down the entire length of the plait, like lacing up a pair of shoes.
When you reach the bottom, tuck the last few strands underneath. Gently press the ends to seal.
Step 4: Bake to Perfection
Preheat your oven to 200°C (400°F). While it heats, place the assembled plait in the refrigerator for 15 minutes to chill. This helps the pastry retain its shape and puff up better.
Remove the plait from the fridge. Brush it generously all over with the beaten egg wash. If using, sprinkle with sesame or poppy seeds.
Bake for 25-30 minutes, or until the pastry is deeply golden brown, puffed, and crisp. If the top is browning too quickly, you can tent it loosely with foil for the last 10 minutes.
Serving & Final Touches
Remove the pastry plait from the oven and let it cool on the baking sheet for at least 10 minutes. This allows the molten cheese to set slightly, making it easier to slice.
Garnish with freshly chopped parsley. Serve warm or at room temperature, sliced into portions. It pairs beautifully with a simple arugula salad dressed with lemon vinaigrette, a dollop of wholegrain mustard, or a bowl of roasted tomato soup.
