Instructions

How to Make Mushroom and Gruyere Tart with Puff Pastry

STEP ONE: Prepare the Puff Pastry

Thaw the puff pastry in the refrigerator according to package directions. Preheat the oven to 400°F (200°C). Lightly dust a large sheet of parchment paper with flour and unroll the puff pastry onto it.

Using a knife or pizza cutter, gently score a ½ inch border around the edge of the pastry.

STEP TWO: Prepare the Mushrooms

Wipe the mushrooms clean and slice them evenly. Heat the olive oil and butter in a frying pan over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant. Add the mushrooms, salt, and black pepper, and cook until softened and most of the liquid has evaporated, about 8-10 minutes. Drain any remaining liquid.

STEP THREE: Assemble the Tart

Sprinkle the shredded Gruyere cheese evenly in the center of the pastry, leaving the border clean. Spread the sautéed mushrooms on top of the cheese. Transfer the pastry to a baking sheet.

STEP FOUR: Bake the Tart

Brush the beaten egg along the border of the pastry. Bake in the preheated oven for 20-25 minutes, or until the pastry is golden brown and puffed. Remove from the oven and top with fresh thyme sprigs. Allow the tart to cool for a few minutes before cutting into pieces and serving warm.

What Are Some Good Substitutions?

• Cheese: Substitute Gruyere with Swiss cheese or sharp cheddar for a different flavor.
• Mushrooms: Use wild mushrooms, such as chanterelles or shiitakes, for an earthier taste.
• Herbs: Replace thyme with rosemary or parsley.

How Can You Change This Recipe Up?

• Diet: Make it vegetarian by using a dairy-free cheese alternative.
• Flavor: Add caramelized onions or sun-dried tomatoes for extra depth.
• Presentation: Use mini tart pans for individual servings, perfect for entertaining.
