For the Dough
- 4 cups all-purpose flour
- 2 tablespoons sugar
- 2 teaspoons baking powder
- 2 teaspoons freshly ground black pepper
- 1 tablespoon fresh leaves thyme
- 1 teaspoon kosher salt
- 11/2 cups unsalted butter, cut into small pieces
- 4 ounces smoked Gouda cheese, grated on the medium-hole side of a box grater (about 1¹⁄3 cups)
- 2 large egg yolks
- 2/3 cup ice water, plus more as needed
For the Galettes
- 4 Granny Smith apples, peeled, halved, cored, and sliced ¼-inch thick
- 4 tablespoons unsalted butter, melted
- 3 tablespoons maple syrup
- 1/2 lemon, zested and juiced
- Kosher salt
- Aged Gouda cheese, for grating
- 1 large egg
- Vanilla ice cream, optional for serving
Make the dough: Place the flour, sugar, baking powder, pepper, thyme, and salt in the bowl of a food processor and process for 10 seconds to combine (if making the dough by hand, whisk the dry ingredients together in a large bowl). Add the butter and smoked Gouda and pulse until there aren’t any pieces larger than a small pea, about eight 1-second pulses (or use your fingers to work the butter into the flour mixture until the butter pieces are no larger than a small pea, and then add the cheese). Add the egg yolks, one at a time, pulsing the mixture between additions. Then, while pulsing, start to drizzle in the water. (If making the dough by hand, use a fork to incorporate the egg yolks and water.) Once all the ice water is added, take a small bit of the dough and squeeze it in your palm. If it comes together readily and doesn’t look dry or crumble apart easily, it is done; if the dough crumbles apart, add another 2 to 3 tablespoons of ice water.
Transfer the dough to a cutting board and press and pat it into a 3/4-inch-thick disk. Divide the dough into six equal pieces (like a pie) and then press each into a 1/2-inch-thick disk (don’t knead the dough—just use your palms to press it into round disks). Wrap each piece in plastic wrap and refrigerate for at least 20 minutes or up to 2 days.
Assemble the galettes: Place the apples in a large bowl. Add the melted butter, maple syrup, lemon zest and juice, and a pinch of salt and toss to combine. Set aside.
Line two rimmed sheet pans with parchment paper or nonstick baking mats. Remove the dough from the refrigerator and let it sit out to soften, 15 minutes. Roll each disk between pieces of plastic wrap or parchment paper into a 9- to 10-inch circle that’s about 1/4-inch thick. Lift the top piece of plastic off each round of dough and divide the apples among them, leaving a 3-inch border at the edges. Fold the edges of the dough over the apple slices, loosely pleating the dough and leaving the center exposed. Use a metal spatula to transfer the galettes to the prepared sheet pans, placing three galettes on each sheet pan. Chill the galettes for 1 hour. (The galettes can be refrigerated for up to 4 hours before baking. I have refrigerated them overnight, and while they were still tasty, they were not quite as well structured. If chilling for more than 1 hour, cover the sheet pan with plastic wrap so the dough doesn’t dry out.)
Adjust one oven rack to the upper-middle position and another to the lower-middle position. Preheat the oven to 375°F.
Grate some of the aged Gouda over each galette. Use a fork to beat the egg with a pinch of salt and 1 tablespoon of water, then use a pastry brush to lightly coat the crust of each galette with the egg wash. Bake until the crust is golden and the apples are tender, 35 to 40 minutes. Serve warm or cooled.
The galettes are best eaten within 1 day of baking; store them at room temperature and warm them in a 325°F oven before serving.
