Ingredients

Scale

Mushroom Mixture

  • 24 ounces cremini mushrooms, diced
  • 1/2 medium yellow onion, chopped
  • 3 cloves garlic, minced
  • 1 tablespoon olive oil
  • 4 ounces mascarpone cheese
  • 4 tablespoons grated parmesan cheese, divided
  • 1 tablespoon chopped fresh thyme, plus extra for serving
  • Salt and pepper, to taste

Pastry

  • 1 sheet puff pastry, thawed

Instructions

  1. Preheat the Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper to prevent sticking and ease cleanup.
  2. Sauté Onion and Garlic: Heat a skillet over medium-high heat. Add the olive oil, chopped onion, and minced garlic. Cook for about 5 minutes until the onions are softened and fragrant.
  3. Cook Mushrooms: Add the diced cremini mushrooms to the skillet. Continue cooking for about 10 minutes, stirring occasionally, until the mushrooms release all their moisture and start to brown around the edges.
  4. Add Cheeses and Thyme: Stir in the mascarpone cheese and 2 tablespoons of grated parmesan cheese. Cook until melted and creamy. Mix in the chopped fresh thyme and season with salt and pepper to taste. Remove from heat.
  5. Prepare the Puff Pastry: Place the thawed puff pastry sheet on the lined baking sheet. Crimp the edges by folding them in slightly to create a small crust around the perimeter.
  6. Assemble the Tart: Spread the creamy mushroom mixture evenly over the puff pastry, staying within the crimped edges. Sprinkle the remaining 2 tablespoons of parmesan cheese evenly on top.
  7. Bake the Tart: Place the baking sheet in the preheated oven and bake for 30 to 35 minutes, or until the pastry is golden brown and puffed up.
  8. Cool and Serve: Remove the tart from the oven and allow it to cool for a few minutes. Sprinkle with extra parmesan cheese and fresh thyme before slicing and serving.

Notes

  • Ensure the puff pastry is fully thawed before using for best puffing results.
  • For a richer flavor, use freshly grated parmesan cheese.
  • This tart is best served warm but can also be enjoyed at room temperature.
  • Variations can include adding a splash of white wine when cooking mushrooms to enhance flavor.
  • Pair the tart with a simple green salad for a complete meal.
