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.

Substitutions & Variations

  • 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 I Customize this Recipe?

  • 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.

Recipe FAQs

Can I use a different type of mushroom in this tart?

Yes, you can use a variety of mushrooms such as cremini, shiitake, or a mix of wild mushrooms. Each type will bring a unique flavor to the tart. Just ensure they are sliced evenly and cooked thoroughly to remove excess moisture.

How do I prevent the puff pastry from becoming soggy?

To prevent the puff pastry from becoming soggy, make sure the mushrooms are fully cooked and all liquid has evaporated before placing them on the pastry. Additionally, you can lightly prick the pastry with a fork before baking to allow steam to escape, which helps keep the crust crisp.

Can I make this mushroom tart ahead of time?

Yes, you can prepare the mushroom filling a day ahead and store it in the refrigerator. Assemble and bake the tart just before serving to ensure the puff pastry remains crisp. If you need to reheat leftovers, bake them in the oven at 350°F (175°C) for about 10 minutes.
