Here is the Mushroom Tart from Great Food Fast. Like anything using puff pastry, this was bound to be great. After using pre-sliced crimini mushrooms, there really is hardly any prep work to this. Having said that, there is a great number of steps involved in creating this masterpiece.
The onions caramelize in one pot, the mushrooms and spinach cook in another, then the puff pastry is rolled and baked separate. So you have a three-ring circus happening simultaneously. If you're not on top of any of these, you risk burning or overcooking any one of them. Luckily I nailed it with help from Nuno at a few key moments. It was almost a relief once complete so we were all able to really enjoyed this.
