This galette des rois recipe is made with two layers of all-butter puff pastry and filled with a pistachio cream, but you can use any nut to make the filling.
Galette des rois is a traditional French pastry made from disks of puff pastry baked with an almond cream filling. A penny, a bean, or even a heat-proof tiny toy is usually hidden within the almond cream and the person who gets the slice with the penny is crowned king (le roi), which is where the name comes from. This dessert is served during epiphany in January, after the Christmas holiday is over.
Tips to stop the filling from leaking
A common problem with puff pastry desserts and hand pies is that the filling can leak out the edges. If you don't take the time to do this step properly, the filling of your galette may seep out between the layers of pastry as it bakes. The filling that leaks out will burn on the sheet pan, leading to so much smoke that it may set off your smoke detector. Here's how to stop this from happening:
- Brush on an egg wash on the surface of the edges (about a 1 inch border all the way around the bottom disk), which will act as a glue when the pastry is in the oven
- Press the edges together of the top and bottom pastry further glue them together.
Another step where things can go wrong is baking the galette properly. There are two layers of pastry to bake through plus an almond cream (or pistachio cream) filling. That's quite thick and it takes a long time to bake properly. You want to bake your pastry until it is a deep, even golden-brown colour on top and underneath. This will lead to a crisp flaky galette that is perfect! A galette des rois can take an hour to bake. Bake it until it's a deep golden brown.
For the pastry, you can either use homemade puff pastry (if you have time) or store-bought puff pastry. When you buy puff pastry, be sure to check the ingredients: invest in a puff pastry that is made with only butter, flour, water, and salt. Some store brands will use alternative fats, sometimes hydrogenated fats, to cut costs. I prefer to buy all-butter puff pastry from my local bakery.
Galette des rois
- 58 grams (¼ cup) unsalted butter room temperature
- 60 grams (½ cup) icing sugar
- 55 grams (½ cup) shelled unsalted pistachios ground in the food processor
- 1.25 mL (¼ teaspoon) Diamond Crystal fine kosher salt
- 1 large eggs
- 5 mL (1 teaspoon) pure vanilla extract
- 10 mL (2 teaspoon) spiced or dark rum
- 600 grams (1¼ lb) all-butter puff pastry
- 1 dried black-eyed pea or any other dried bean (optional if celebrating Epiphany)
- 1 large egg whisked with a little water for egg wash
- 1 crown optional
- Line a large sheet pan with parchment paper. Set aside
- In the bowl, using an electric hand mixer, cream the butter and the sugar.
- Grind the pistachios finely in a mini food processor.
- Add the ground nuts, then add the egg.
- Add the vanilla and rum. Mix well
- Transfer to a small container, and refrigerate overnight (or until cold).
- Divide the puff pastry in 2.
- Roll one half to a 12-inch circle (or a little bigger, and trim to a 12-inch circle). Place on the prepared sheet pan.
- Spoon the filling into the center of the disc, leaving the outer edge free for egg wash.
- Place the black-eyed pea in the filling, close to the edge, and in the direction that you would cut the galette (to avoid slicing it in half).
- Prepare the egg wash by mixing the egg with a little water and a pinch of salt to thin it out.
- Brush the edges with a thin layer of egg wash.
- Roll the other half to a slightly larger disc. And place on top.
- Press down the edges really, really well!
- Trim the edges to make them pretty, if you’d like.
- Brush the top pastry lightly and evenly with egg wash. Let stand 1 minute to dry a little, then coat it again.
- Draw pretty patterns with a knife (don’t pierce the pastry!) on the top pastry..
- Pierce the pastry to allow for venting.
- Refrigerate for at least 1 hour.
- Preheat the oven to 375 ºF.
- Bake the galette at 375°F for 45 to 50 minutes.
