Pretty much anything you put on puff pastry is going to be great- it’s buttery, flaky, and delicious! So when I got some potatoes and mushrooms in my bag I thought I would experiment a little. This tart took about 30 minutes from beginning to end and was delicious. I think next time I will add more mushrooms and use some colorful purple potatoes as well. I actually thought I had purple potatoes because the skin had a purple tint, but they were white when I cut them open so not sure what type they were! Either way they were good. Next time I make this I think I will also roast the sliced potatoes in the oven first so they get a little browned before adding them to the tart. Th potatoes will look prettier that way. In the end I topped it with some fresh miner’s lettuce to add some nice color, but you could use other greens such as arugula.
1 box puff pastry, thawed
1 large potato, thinly sliced
1/2 large shallot, chopped
1 cup shiitake mushrooms, cleaned and cut into chunks
5 ounces truffled goat cheese (I used half)
Salt and Pepper, to taste
Truffle oil, for drizzle (optional)
Handful of pretty greens- such as miner’s lettuce or arugula- for topping
Preheat the oven to 400 degrees. Place the thawed dough on a baking sheet lined with parchment. I sprinkled a little flour to help the dough from sticking. With a knife, make a 1/2 inch border around the tart, without going through to the other side. Poke some holes in the center of the tart with a fork to let the heat escape while cooking. Brush with the egg and bake in the oven for 10-15 minutes until golden. You will see that it puffs up a lot when it cooks, but don’t worry! When you remove it from the oven, poke a few additional holes with a sharp knife then while wearing oven mitts, gently press down on the dough to release the air- it will flatten.
In a pot of boiling water, cook the potatoes until fork tender. Careful not overcook them! Alternatively, you could also drizzle with olive oil and bake in the oven for 10-15 minutes until they start to brown- which is what I will try next time. Remove and set aside. Add some olive oil to a pan and cook the shallots for about 2 minutes. Add the mushrooms and continue for another 5 minutes until softened and cooked through. When the dough is ready, top with the potatoes, followed by the mushroom and shallot mixture. Break up the cheese and add as much as you like. Place in oven for 10 minutes. Once removed, drizzle with some truffle oil, fresh ground pepper, and a small handful of greens. Serve warm. Enjoy!
