When the season rolls around and sweet, juicy blackberries are at their peak, a fresh blackberry pie is the perfect way to celebrate. It's also an excellent excuse to visit a you-pick farm and fill pints with the sweet-tart berries (get enough for this blackberry cobbler, too). Then you can come home and enjoy the fruits of your labor. All this juicy berry pie is missing is a big dollop of whipped cream or a heaping scoop of vanilla bean ice cream to put this summer dessert over the top!
How do you thicken a blackberry pie?
Juicy fresh fruit pies need starch to thicken the filling so it doesn't spill out when you make a slice. You can use cornstarch, tapioca, or all-purpose flour. This recipe calls for cornstarch. Rather than waiting for the fruit juice to boil in the oven—which activates the cornstarch’s thickening power—you jump-start the process in this recipe. The berries are tossed with sugar and left to release their juice, which is then whisked with cornstarch and brought to a boil on the stove. The thickened juice is folded back into the fruit, and everything is encased in pie crust. The result is a filling that sets up nicely but is still unbelievably juicy.
How do you keep blackberry pie crust from getting soggy?
The first step to preventing a soggy bottom is to thicken your filling properly. It's also key to fully bake and crisp up the bottom crust. To help this pie crust crisp up quickly, bake the pie on a preheated baking sheet. You'll get a golden, flaky crust through and through.
What's the best way to store leftover blackberry pie?
This pie will be best the day it's made, but if you somehow don't finish it in one sitting, you can wrap leftovers tightly in plastic wrap and keep them at room temperature for up to two days. If you want to store the pie for longer, keep it in the fridge for up to two more days. Hint: Try a slice for breakfast the next morning!

Ingredients
- 6 cups
fresh blackberries (4 (6-oz.) containers)
- 3/4 cup
granulated sugar
- 2 tsp.
lemon zest plus 1 tbsp. lemon juice
All-purpose flour, for dusting
- 1
recipe All-Butter Pie Crust (2 crusts)
- 1/4 cup
cornstarch
- 1/4 tsp.
kosher salt
- 2 Tbsp.
salted butter
- 1
large egg, lightly beaten
- 2 Tbsp.
turbinado sugar
Directions
- Step 1In a large bowl, combine the blackberries, granulated sugar, lemon zest, and lemon juice. Cover and let sit at room temperature for 1 hour so the juices are drawn out and the berries soften, stirring occasionally.
- Step 2Position an oven rack in the lower third of the oven and preheat to 425°F. Place a foil-lined rimmed baking sheet on the rack to preheat.
- Step 3On a floured surface, roll out 1 pie crust into a 12-inch round, starting at the center and working your way out. (Sprinkle flour over the top of the dough if it's a bit sticky.) Carefully lift the dough and place it in a 9-inch pie dish (not a deep dish); gently press the dough against the sides of the dish. Trim the overhanging dough to 1 inch at the edge of the pie dish. Cover and refrigerate until ready to use.
- Step 4On a floured surface, roll out the second pie crust into a 10-inch round. Place the dough on a baking sheet or large plate, cover, and refrigerate until ready to use.
- Step 5Drain the blackberries, reserving about ½ cup of the liquid. Discard any remaining liquid. Return the drained blackberries to the large bowl.
- Step 6In a medium saucepan, combine the cornstarch and salt. Gradually whisk in the reserved blackberry juice. Bring to a boil over medium heat, stirring constantly to prevent lumps. Use a rubber spatula to scrape the bottom and sides of the saucepan. Reduce the heat to medium-low, and cook until thickened, 2 to 3 minutes. Reduce the heat to low and whisk in the butter. When the mixture is well combined and glossy, remove from the heat. Pour the mixture over the blackberries, folding to combine. Scoop the mixture into the pie crust set in the pie dish.
- Step 7Place the remaining pie crust over the top of the berries. Trim the excess dough around the edges, and crimp the top and bottom crusts together to seal them. Cut a few vent holes in the top crust. Brush the top crust with the beaten egg and sprinkle with the turbinado sugar.
- Step 8Bake the pie on the preheated baking sheet until the filling is bubbly and the crust is deeply golden, 50 minutes to 1 hour, rotating the pie halfway through baking. (Cover the pie with foil if the crust starts getting too dark after 40 minutes.)
- Step 9Allow the pie to cool to room temperature on a wire rack before slicing, about 4 hours.
Tip: This pie lets the blackberries shine with just a hint of lemon. For a warmer flavor, you can add other dry ground spices such as cinnamon, nutmeg, cardamom, or ginger when you add the cornstarch.
