This tart is as beautiful to look at as it is to eat. Serve this potato tart as an appetizer or cut a larger serving for a healthy vegetarian dinner. If you don't have a mandoline, use your sharpest knife to slice the potatoes and celeriac as thin as possible.

  • Roll puff pastry on a lightly floured surface into a 12-by-10-inch rectangle. Transfer to the prepared pan.

  • Combine Gruyère, mascarpone, Parmesan, shallot and thyme in a small bowl. Spread the mixture evenly over the pastry, leaving a 1/2-inch border. Using a sharp paring knife, lightly score the border. Toss potatoes and celeriac with oil in a large bowl. Arrange the vegetables, slightly overlapping, in a single layer over the cheese mixture. Sprinkle with salt and pepper.

  • Bake the tart until the crust is golden brown and the vegetables are tender, 40 to 45 minutes. Garnish with more thyme, if desired. Serve warm or at room temperature.
