Potato Tart

Buttery, flakey puff pastry sprinkled with Gruyere and topped with creamy slices of potatoes makes for an indulgent and delicious treat! This tart comes together so quickly but really packs a lot of visual punch for the effort making it a perfect dish for entertaining. I loved this with a healthy sprinkle of sea salt flakes but you can add any of your favorite herbs and switch the cheeses up as well.

A while back I had an amazing pizza with slices of creamy potatoes covering the top, so delicious I was inspired to make this tart! I thought a fish scale pattern would be easy to render given the shape of the potato slices and it was! Alternating between the purple and white slices definitely adds a lot of visual interest but this will still look great if you only have one color of potato to work with.

  1. Preheat to 400 degrees F. Par boil the baby potatoes until tender. Flour a surface. Roll out a sheet of puff pastry. Using a ruler, trim the pastry into a square. Transfer to a baking sheet with parchment paper. Score the dough about 1 inch from the edge. Thinly slice the potatoes. Parboil the white baby potatoes slices for a few minutes or until tender. Repeat the process for the purple potato slices.
  2. Use a fork to pierce the inside of the scored square. Bake the shell for about 10 minutes. Use a sharp knife to thinly slice potatoes. Grate about 1/2 cup cheese. 
  3. Take the pastry shell out of the oven and add the shredded gruyere.
  4. Add potato slices. 
  5. Arrange the slices so that they alternate white and purple pattern.
  6. Brush with olive oil and sprinkle sea salt. Bake for 15-20 minutes.

A FEW TIPS

  • Using baby potatoes will give you the best sized pattern. Large potatoes are just too large for this size of tart.
  • I used a ruler to get a perfect border for this tart. Cut a square shape then use a knife to carefully cut a border 1/2 and inch in by pressing the knife half way through the dough.
  • Keep a close eye on the pastry when you’re baking. If your oven heats unevenly you should turn it halfway though baking.
  • If you don’t want to break a ruler out you can get the exact same taste with a more rustic look by just eyeballing the pastry dough.
