Flaky Mushroom And Gruyère Puff Pastry Braid

The first time I made this puff pastry braid was on a night when the power had gone out at our house. Candles flickered on the counter, the kids were bundled under blankets, and I needed something warm, filling, and a little special to keep spirits up. With just one sheet of puff pastry in the freezer and a drawer full of mushrooms, I started pulling things together.

The smell of butter hitting the pan, onions softening, and mushrooms sizzling filled the kitchen in the quietest, coziest way. When the Gruyère melted into the cream cheese, it turned into this luxurious, silky filling that felt far fancier than the circumstances.

As I braided the pastry by candlelight, I couldn’t help but laugh—sometimes the best meals come from moments when nothing goes according to plan. When it finally came out of the oven, golden and puffed, we all gathered around the table with slices in hand, dipping pieces into little bowls of mustard and eating by lantern light.

Key Ingredients

• 1 sheet puff pastry, thawed
• 2 tablespoons unsalted butter
• 2 tablespoons olive oil
• 1 small yellow onion, finely diced
• 2 cloves garlic, minced
• 10 oz cremini mushrooms, sliced
• 1 teaspoon fresh thyme leaves (or ½ tsp dried)
• Salt and black pepper, to taste
• ¼ cup dry white wine (optional)
• 8 oz cream cheese
• ¾ cup Parmesan cheese, finely grated
• ½ cup Gruyère cheese, grated
• 1 teaspoon Dijon mustard (optional)
• 2 large eggs, divided
• Fresh parsley, chopped (for garnish)

Tools Needed

• Large skillet
• Wooden spoon or spatula
• Sharp knife
• Cutting board
• Baking tray
• Parchment paper
• Pastry brush
• Mixing bowl

Cooking Instructions

Step 1: Preheat the oven
Set oven to 350°F (180°C). Line a baking tray with parchment paper.

Step 2: Cook the onion and garlic
In a large skillet, heat butter and olive oil over medium heat. Add onion and cook for about 5 minutes until softened and translucent. Stir in garlic and cook for another minute.

Step 3: Sauté the mushrooms
Add mushrooms to the skillet and cook until browned and the liquid has evaporated, about 8 minutes. The pan should look dry before moving on.

Step 4: Add seasoning and wine
Stir in thyme, salt, and pepper. If using wine, pour it in and cook until fully absorbed. Lower the heat.

Step 5: Make the filling
Add cream cheese, Parmesan, and Dijon mustard. Stir until smooth and creamy. Remove from heat, then fold in Gruyère until just melted.

Step 6: Add the egg
Beat one egg and stir it quickly into the filling to help bind everything together. Let the mixture cool slightly before filling the pastry.

Step 7: Prepare the pastry
Unroll the puff pastry. On each long side, cut 8 diagonal strips, leaving the center intact for the filling.

Step 8: Fill and braid
Spread the filling down the center, leaving 1 inch of space at the top and bottom. Fold the top and bottom edges over, then alternate strips from each side to create a braid.

Step 9: Brush with egg wash
Transfer to the lined tray using parchment. Beat the second egg and brush it evenly over the braid.

Step 10: Bake
Bake for 20–22 minutes until golden brown and puffed. The pastry should be crisp and flaky.

Step 11: Rest and garnish
Cool for 10 minutes before slicing. Sprinkle with fresh parsley before serving.

Troubleshooting Tip: If your pastry looks pale after 20 minutes, give it an extra 3–5 minutes, but keep an eye on it to avoid over-browning.

Mistakes to Avoid & Solutions

Overloading the pastry: Too much filling makes it soggy. Solution: Stick to the amounts given.

Not cooling the filling: Hot filling melts the pastry before baking. Solution: Let it rest 5–10 minutes first.

Skipping the egg wash: Without it, you’ll miss the golden shine. Solution: Brush with beaten egg before baking.

Cutting too soon: The filling needs to settle. Solution: Wait 10 minutes before slicing.

Wet mushrooms: If you don’t cook off all the liquid, the braid turns mushy. Solution: Cook until the skillet looks dry.
