Mushroom Tart

This mushroom tart is the perfect appetizer, light lunch, or even a main that you can make all year round. Garlicky, buttery mushrooms are piled on flaky all-butter puff pastry with cheese. It's utterly and mouthwateringly delicious, and you won't be able to stop at just one slice!

Ingredients

  • 2 tablespoons olive oil
  • 3 cups (200g) mushrooms
  • ½ teaspoon salt
  • ¼ teaspoon ground black pepper
  • 1 tablespoon butter optional
  • 2 cloves garlic minced
  • 1 tablespoon fresh thyme chopped
  • 1 sheet puff pastry
  • 1½ cups (125g) grated cheese Edam, Gruyere, raclette, or a mix of cheddar and mozzarella.
  • 1 egg for the egg wash
  • ¼ teaspoon chili flakes optional

Instructions

  • Preheat oven to 180°C/350°F (160°C/320°F fan).
  • On medium heat, heat olive oil in a pan. Add the mushrooms, season with salt and pepper, and cook stirring occasionally until the mushrooms release their liquids and it cooks off (about 8 minutes).
  • Melt butter (optional)*, and saute garlic until its fragrant. Add thyme, cook for a minute, and remove from heat.
  • Line a baking sheet with parchment paper, this will prevent the puff pastry from sticking to the sheet pan. Unroll the puff pastry sheet, then score the edges using a sharp knife leaving a 1-inch border. Then using a fork, prick the puff pastry sheet.
  • Top the puff pastry with grated cheese, followed by sauteed mushrooms.
  • Using a pastry brush, brush the border with an egg wash.
  • Bake for 12-15 minutes, or until the puff pastry is puffed and lightly browned.
  • Sprinkle some chili flakes if desired, then cut into 6 squares, and serve warm.

Notes

  • If using frozen puff pastry, let it thaw completely before using (preferably overnight in the fridge).
  • Keep the puff pastry in the fridge until you're ready to use as otherwise it will melt and become too soft and difficult to handle.
  • I used an All-Butter Puff Pastry sheet that was 320g in weight, which is around 11 ounces.
  • Adding butter to the sauteed mushrooms is optional, it adds more flavor but if you don't want the tart to be too buttery then omit the butter.
  • Feel free to saute an onion with the mushroom.
  • Other herbs that go well with the filling are rosemary and oregano
