Potato, Mushrooms, Caramelized Onions and Brie Cheese Tart

by Erica Dinho on June 29, 2010

Mushroom,Potato Tart

This tart is as simple as can be and almost any vegetables can be used. That’s what I love about tarts and pies, they are so versatile. In this case, I made a potato, mushroom, caramelized onions with brie topping, but you could use any cheese or even a combination of different kinds of cheeses.

Serve with a green salad on the side and enjoy it!



  • 1 sheet frozen puff pastry
  • 4 oz brie cheese, cut into small pieces
  • 2 tablespoons olive oil
  • 1 onion, thinly sliced
  • 1 cup mushrooms, sliced
  • 2 large potatoes, peeled and sliced
  • 1/4 teaspoon ground cumin
  • 1/4 teaspoon ground paprika
  • 1/2 teaspoon fresh thyme
  • 1/2 teaspoon fresh parsley
  • Salt and pepper
  • 1 beaten egg

Mushrooms and Brie cheese Tart


  1. In a medium non-stick pan, heat the olive oil over medium heat. Add the potato slices in a single layer, add the cumin, paprika, thyme and parsley and fry about 4 minutes on each side or until tender.
  2. With a slotted spoon, transfer the potatoes to a plate lined with paper towel and set aside. Add the onions and mushrooms to the pan and cook for about 10 minutes or until caramelized.
  3. Preheat the oven to 400 F.
  4. Line a baking sheet with parchment paper. Place the puff pastry on the baking sheet. Spread the potatoes, mushrooms and onions on top of the pastry, leaving about 1 inch border.
  5. Top with the brie the cheese. Season with salt and pepper. brush the edge of the tart with the egg.
  6. Bake for about 25 to 30 minutes or until the pastry is golden brown.

Lovely! I love how the toppings sink into the puff pastry as it bakes, forming its own ‘bowl’. Versatility is wonderful in a dish like this because it means we can enjoy it all year with whatever vegetables are currently in season. As for cheese, there are so many different ones to try; my husband would probably vote for blues while I love goat cheeses. 8-)

Wonderful pie. In Greece pies called pites were meant to be made with anything available a simple dough to make phyllo and a filling.

I love all the ingredients you used. Yum!

I’ve made them with tomato, basil, artichoke and ricotta cheese.

I love that you used the brie on this tart. Isn’t brie the best? I love that stuff!

I am a sucker for any kind of tart, and I love the combination of flavors you’ve got in this one. Looks terrific.

Delicious combo for your tart, Erica! I love it and am copying the recipe in a minute.
It’s such fun to experiment with puff pastry, isn’t it? I made a galette with wild mushrooms and stilton for my son the other night…with puff pastry instead of the regular pastry called for. It was sheer heaven.

That looks wonderful–like it would be a quick and easy way to enjoy a decadent meal, perhaps with a simple green salad and a crisp, fruity glass of wine!
