What is a Galette?

A galette is a French, flat, round pastry topped with thinly sliced ingredients. It is pronounced guh-let and in English means ‘flat cake’. The pastry is free-form, as the sides of the pastry are folded slightly over the top of the filling and crimped, to loosely keep the filling in, and is then baked.

It can be a sweet or savory dish, and the most common ingredients are vegetarian like fruits, vegetables and cheese. There are other versions of the galette: like the galette Bretonne out of Brittany (which is actually a crepe), and the galette de rois (king cake that is made with puff pastry).

In this recipe, the thinly sliced potatoes are arranged and layered into a circle, adding to the rustic qualities of a classic galette.

Step 1: Prep Galette Ingredients

Galette ingredients consist of a basic pastry and a filling.

Add the egg and 2 tbsp. cold water and work the mixture together just until it forms a ball (you can add 1 more tbsp. cold water if needed). Flatten into a disc, cover with plastic wrap and chill for 30 minutes.

Preheat oven to 425°F and line a baking sheet or pizza pan with parchment paper. Slice the potatoes with a mandoline to make very thin slices.

Step 6: Mix Potatoes With Pesto

On a lightly floured surface, roll out the dough into a circle that is approximately 13”-14” in diameter. Transfer to the parchment-lined pan.

Step 8: Add the Filling

Layer the potato slices starting from the center of the pastry circle, leaving a 2” border around the edge. Sprinkle with some salt and pepper.

Step 9: Fold the Pastry Edges Over the Potatoes

Fold the dough border up around the edges to partially enclose the potato filling. The center will remain open.

Step 10: Bake the Potato Galette

Step 11: Serve!

Tips & Tweaks

While the steps are easy, always be cautious when using a mandoline to slice potatoes. Here are some tips to help you stay safe using a mandoline:

  1. Make sure the blade is sharp for more control.
  2. Use the mandoline on a flat surface.
  3. Always use the hand guard and inspect it with each use, as well as cut-resistant gloves, if you have a pair.

You can add a variety of vegetables and/or spices for different flavors and textures. Since pesto is mixed into this recipe, adding some spinach is a good tweak because it is leafy and green like the basil in pesto and it adds some more nutrition to the dish. If you prefer a sun-dried tomato pesto, give that a try. If you are serving this galette over the holidays for guests, try baking one with basil pesto and one with tomato pesto for a beautiful red and green contrast on the dinner table.
