This delightful Potato Leek Tart features a crispy puff pastry crust and a creamy filling of tender potatoes and leeks. It’s a comforting dish that’s perfect for any occasion.
In a large bowl, combine the thinly sliced potatoes with the leek mixture. Season with salt and pepper to enhance the flavor.
In a separate bowl, whisk together the cream, eggs, and Dijon mustard.
Spread the potato-leek mixture evenly over the puff pastry. Pour the cream mixture over the filling and optionally sprinkle the grated Gruyère cheese on top.
Fold the edges of the puff pastry carefully over the filling, leaving a small gap in the center for steam to escape.
Bake the tart in the preheated oven for 30-35 minutes until the puff pastry is golden brown and the filling is set.
Remove the tart from the oven and let it cool for about 10 minutes before slicing and serving.
