How to make this mushroom tart recipe

Gather your ingredients. You’ll need the following:

  • Mushrooms – Any kind of mushrooms works but I love using baby bella (also known as cremini) mushrooms. You could also use white button mushrooms.
  • Puff Pastry – any store-bought puff pastry works fine. If frozen, make sure to defrost according to the instructions on the package. You could also use any homemade puff pastry.
  • Seasonings –  shallots, dried thyme, garlic cloves, and balsamic vinegar give amazing flavor to this mushroom tart.
  • Cheese – I use both gruyere cheese and parmesan cheese.
  • Oil, butter, and egg – You’ll need to cook the shallots, garlic and mushrooms in a little fat before adding them to the tart. An egg wash will make the puff pastry nice and golden.
Ingredients to make the recipe.
  • Preheat the oven to 375 degrees Fahrenheit. Heat the butter in a skillet over medium heat. Add the shallots, and dried thyme and saute for 2-3 minutes.
  • Add the garlic and saute until fragrant. Then remove the shallots and garlic from the skillet.

  • Add the olive oil to the skillet. Once it is heated add the mushrooms in a single layer. Cook in batches if necessary, stirring occasionally.
  • Once the mushrooms are browned, add the shallots and garlic back into the skillet, followed by the balsamic vinegar. Cook until the vinegar caramelizes.

  • Place the pastry sheet on a sheet pan and use a knife to score the edges of the puff pastry creating a border. Then poke holes in the bottom of the puff pastry using a fork. Do not poke holes in the border
  • Top the puff pastry with gruyere and parmesan cheese, followed by the mushroom mixture. Brush the egg on the border of the puff pastry. Bake in preheated oven for 20-25 minutes or until golden. Top with chopped parsley before serving.

What are the best mushrooms to use?

I used cremini mushrooms to make this tart, but you can use any fresh mushrooms you like or a mix of different varieties. Portobello, chestnut or shitake will all work great. Slice them fairly thinly before cooking, and be sure to brown them well to get rid of their moisture.

Can you make it ahead of time?

I prefer to serve this mushroom tart warm out of the oven, but leftovers will keep well covered in the fridge for up to 3 days and can be served cold or reheated. You can cook up the mushrooms a day or two ahead of time and keep the refrigerated, that way it will just take a few minutes to prep before baking.

What do you serve it with?

This flavorful vegetarian tart is wonderful served up with a side salad for a brunch, lunch or light dinner. I like to garnish it with some fresh parsley for a pop of color. Try it with some of these favorites salads:

Recipe Notes and Tips

  • Be sure to cook the mushrooms well to remove the water that they hold. This will help to stop the pastry from getting soggy.
  • If your puff pastry sheet is frozen, be sure to allow time for it to defrost before topping and baking.
  • I use dried thyme, but other dried herbs can be used.
  • Try adding some blue cheese or crispy bacon bits to the tart for a different flavor.
