Detailed Directions and Instructions
Preheat the Oven
Place a baking tray in the oven. Turn the oven on and preheat to 210°C / 410°F (190°C fan).
Cook the Mushrooms
Heat the olive oil and butter in a frying pan over medium-high heat. Add the sliced mushrooms, salt, and pepper. Cook for approximately 5 minutes, stirring regularly, until the mushrooms become soft. Once cooked, transfer the mushrooms to a colander placed over a bowl to drain any excess liquid.
Prepare the Base
Lay a sheet of baking paper or parchment paper on the countertop. Place the puff pastry on top of the baking paper. Fold the edges of the puff pastry inward to create a 1 cm / 0.4″ border. Brush the folded edges with the melted butter.
Assemble the Tart
Evenly spread the grated Gruyère cheese over the prepared puff pastry. Top the cheese with the sautéed mushrooms, distributing them evenly.
Bake the Tart
Carefully lift the baking paper along with the assembled tart and place it onto the hot baking tray in the preheated oven. Bake for 30 minutes, or until the pastry is golden and crisp, ensuring both the sides and the underside are cooked thoroughly.
Finish and Serve
Once baked, sprinkle fresh thyme leaves and salt flakes over the top of the tart. For an added touch of flavor, drizzle with truffle oil or high-quality extra virgin olive oil, although this step is optional. Cut the tart into portions and serve hot.
Notes
Note 1
Ensure that the puff pastry is barely thawed to maintain its flakiness during baking.
Note 2
Gruyère cheese adds a rich flavor and meltability, making it an excellent choice for this dish.
Note 3
Slice the Swiss brown mushrooms to approximately 0.5 cm thickness for even cooking.
Note 4
A drizzle of truffle oil or high-quality extra virgin olive oil enhances the flavor profile of the tart.
