    For the Tart:

    • 1 sheet puff pastry
    • White and purple baby potatoes
    • ½ cup gruyere cheese 120ml shredded
    • sprinkle sea salt
    • 1 tsp olive oil



      For the Tart:

      • Preheat to 400 degrees F. Thinly slice the raw potatoes. 
      • Slice the white nParboil the white baby potatoes slices for a few minutes or until tender, remove and set aside on a paper towel. Repeat the process for the purple potato slices. 
      • 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.
      • Using a fork, 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.
      • Take the pastry shell out of the oven and add the shredded gruyere.
      • Arrange the potato slices so that they alternate white and purple pattern.
      • Brush with olive oil and sprinkle sea salt.
      • Bake for 15-20 min.



      • 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.
