Ingredients
Scale
- 1 sheet puff pastry, thawed
- 2 tablespoons unsalted butter, divided
- 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 1/2 teaspoon dried)
- Salt and black pepper, to taste
- 1/4 cup dry white wine (optional)
- 8 oz cream cheese, at room temperature
- 3/4 cup Parmesan cheese, finely grated
- 1/2 cup Gruyère cheese, grated
- 1 teaspoon Dijon mustard (optional)
- 2 large eggs, divided (1 for filling, 1 for egg wash)
- Fresh parsley, chopped (for garnish)
Instructions
- Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
- Heat 1 tablespoon butter and 1 tablespoon olive oil in a large skillet over medium heat.
- Sauté the onion until soft and translucent, about 5 minutes.
- Add the garlic and cook for 30 seconds until fragrant.
- Add the sliced mushrooms and the remaining tablespoon of olive oil; cook until they release liquid and it evaporates, about 6–8 minutes.
- Stir in the thyme, salt, and pepper; cook 1 minute more.
- Pour in the white wine (if using) and simmer until mostly evaporated, 2–3 minutes. Remove from heat and let cool slightly.
- In a bowl, beat 1 egg and mix into the cream cheese along with the Parmesan, Gruyère, and Dijon mustard until smooth.
- Fold the cooled mushroom mixture into the cheese mixture and adjust seasoning.
- Roll the puff pastry sheet on a floured surface into a roughly 10×12-inch rectangle. Trim edges if needed.
- Cut long diagonal strips (about 1-inch wide) along the two long sides of the pastry, leaving a 3–4 inch center strip intact for the filling.
- Spread the mushroom and cheese filling down the center strip, leaving a small border at each end.
- Fold the end flaps over the filling, then braid by folding alternating strips from each side over the filling, overlapping slightly to seal.
- Beat the remaining egg and brush the braid all over for a shiny, golden finish.
- Transfer to the prepared baking sheet and bake for 25–30 minutes, or until puffed and deep golden brown.
- Let rest for 5–10 minutes, garnish with chopped parsley, slice, and serve warm.
Notes
Use room-temperature cream cheese for a smoother filling. Don’t overcrowd the skillet with mushrooms to prevent steaming.
