Sweet dark berries, savory cheese and flaky pastry melt in your mouth when you bite into this blackberry galette. The crisp bottom holds the fillings steady when you slice this juicy tart for you and your guests.
Combine the flour, sugar and salt in a medium bowl. Add the cold butter and work it with your fingers or a fork into the flour, until it is grainy.
1 ¼ cups all-purpose flour, ¼ cup sugar, ¼ teaspoon salt, ½ cup cold butter
Add the egg and water and combine with your hands until you get a soft, smooth dough. If it is sticky, add a little more flour. Flatten into a disc, cover with plastic wrap and chill for 30 minutes.
1 egg, 1 tablespoon cold water
Preheat the oven to 400ºF.
Take the dough out of the fridge and let sit for 5 minutes. On a lightly floured surface, roll it out into a large circle that is 12” in diameter. Transfer the dough circle to a rimmed baking sheet lined with parchment paper (you can also use a pizza pan or cast iron pan).
Add the frozen blackberries and lemon zest to the center of the pastry circle, leaving a 2-inch border around the edges. Whisk the sugar, salt and cornstarch together in a bowl. Sprinkle evenly over the blackberries. Add the brie cheese pieces evenly on top.
Bake in the preheated oven until the crust is golden and the filling is hot and bubbling, about 35 to 40 minutes.
Let sit for 15 minutes to cool and set the filling as it will be very hot. Garnish with fresh thyme if desired, slice and serve!
Notes
If you use fresh blackberries instead of frozen, it might bake a bit quicker so keep an eye on it.
For best results, when you're serving this galette as dessert at a fall or winter get-together, serve it shortly after you remove it from the oven when the filling is slightly cooled but not too hot. Add some creaminess and contrast with a scoop of cold vanilla ice cream or frozen yogurt.
