Recipe: Potato Tart - Potato and Gruyere "Gratin" Galette

Recipe: Potato Tarts

Potato and Gruyere "Gratin" Galette

Baked 09.05.14

Potato and Gruyere "Gratin" Galette:

Baby Yellow Potatoes with Course-Ground Mustard and Gruyere Cheese

This is a free-form tart or galette - no ring mold necessary. The ingredients are arranged on top of a rolled circle of dough that has been formed to have a slightly raised rim. 

Loaded with potatoes and melted gruyere cheese, the final product is not dissimilar to what could be called a potato pizza.

- The Recipe -

Potato and Gruyere "Gratin" Galette:

Baby Yellow Potatoes with Course-Ground Mustard and Gruyere Cheese

YieldOne 9" Galette 

  • 240g Pate Brisee (link to dough recipe)
  • Baby Yellow Potatoes: 350g (approximately 2 cups, sliced 1/8")
  • Coarse Ground Mustard: 50g (3 Tbls)
  • Butter: 30g (2 Tbls)
  • Gruyere Cheese: 150g (1.5 Cups, grated)
  • Salt to taste


1. Par-cook the potatoes: Wash and dry the potatoes. Slice the potatoes into 1/8" slices. 

Place the potatoes in a medium pot of cold, salted water over high heat. Once the water reaches a boil, cook the potatoes for one minute. Remove the pot from the heat, drain the water and place the potatoes in a single layer on a sheet pan to cool. The potatoes should be undercooked and still have a crunch. They will finish cooking when the galette is baked.

Chef’s note: To prevent oxidation while you work, place the cut potatoes in a bowl of cold water with a little bit of vinegar.

2. Prepare the galette shell: On a clean, dry, lightly floured surface, roll the pate brisee into a circle measuring approximately 11". Trim the edges to achieve a more uniform circle if desired. 

Transfer the shell to a parchment lined sheet pan.

Working around the perimeter of the shell, roll the edge of the crust up and over to form a small lip. The lip should be just high enough to prevent the cheese from spilling out when it melts during baking - no more than 1/4". 

Decorate the edge of the crust, if desired: an easy pattern can be made using a knife or fork. 

Chef’s note: When using a tool to press a pattern into a dough, dip it in flour to prevent it from sticking.

3. Evenly distribute about 2/3 (100g) of the grated gruyere cheese on the bottom of the unbaked galette shell.

4. Melt the butter and stir it with the mustard until combined. In a large bowl, toss the cooled potato slices with the mustard mixture. 

5. Arrange the potato slices in a circular pattern on top of the cheese. Start at the outer edge of the galette, overlapping each slice until you form a complete circle. Start another circle that slightly overlaps this outer circle. Continue until you reach the center of the galette. 

Chef’s note: The thinner you slice the potatoes, the tighter you can layer each piece for a more visually impressive design.

6. Cover the potatoes with the remaining cheese (50g) and dust with salt to taste. Bake the galette at 350 degrees Fahrenheit for about 35 minutes - until the crust is dry on the bottom, the cheese has fully melted, and the potatoes are slightly browned on top.
