How to Make the Tart

Making this Mushroom Tart is incredibly easy. Start by sauteing mushrooms and onion until browned and fragrant. Add in garlic, fresh thyme, salt, and pepper. Top an unrolled puff pastry sheet with shredded cheese, then the mushroom mixture. Bake until golden and crisp. Cut into squares and serve.

Dough for Mushroom Tart

For this tart, I recommend puff pastry dough for a crisp, flaky, and golden crust.

To make this recipe even easier, I recommend using Jus-Rol™ Puff Pastry Dough. This flaky, layered dough is ready to bake at any moment. Unlike traditional puff pastry dough, you find in the freezer that needs to be defrosted, this refrigerated dough is ready for baking when you are.

It’s available in the refrigerated dairy case at a grocery store near you. Also look for their Round & Thin Pizza Crust, Family Size Pizza Crust, Flatbread Dough & Pie Crust.

Tips for this Recipe

  • Saute the mushrooms until browned, and liquids have evaporated. It may seem like a lot of mushrooms, but they’ll shrink plenty
  • Be sure to use the parchment paper under the puff pastry dough to prevent sticking
  • Scoring the edge of the dough helps the edge puff. Pricking the center of the dough before baking allows steam to release and prevents the center from puffing
  • The egg wash helps to brown the edges

  • 1 tablespoon olive oil
  • 1 medium yellow onion, diced
  • 4-6 cups sliced Baby Bella mushrooms, about 16-ounces
  • ½ teaspoon salt
  • ¼ teaspoon ground black pepper
  • 2 cloves minced garlic
  • 1 tablespoon fresh thyme leaves
  • 1 sheet Jus-Rol™ Puff Pastry Dough
  • 8- ounces shredded Italian cheese blend, or Mozzarella
  • 1 medium egg, lightly beaten


  • Preheat the oven to 425° F. Remove the Puff Pastry Dough from the fridge at let sit at room temp.
  • Meanwhile, heat olive oil in a pan to medium heat. Add onions and saute until fragrant and slightly translucent, about 5 minutes. Add the mushrooms, salt, and pepper. Cook stirring occasionally until the mushrooms are browned and have released liquids, then the liquid evaporates, about 8 minutes.
  • Stir in garlic and thyme and cook 2 minutes more. Remove the pan from the heat.
  • Unroll the puff pastry sheet on a baking sheet, keeping the parchment on the bottom to prevent sticking. Score the edges using a sharp knife, leaving a 1-inch border. Then use a fork to prick the center puff pastry sheet every 2 to 3 inches.
  • Top the puff pastry with grated cheese, leaving the 1-inch border of dough, followed by the sauteed mushrooms and onion mixture.
  • Using a pastry brush, brush the dough border with the beaten egg to help with browning.
  • Bake for 14-16 minutes, or until the puff pastry edges are golden brown.
  • Remove from oven and let cool 2-3 minutes. Cut into squares and serve.
