This Granny Smith Apple Pie recipe delivers a flaky, buttery crust packed with tart, juicy green apples and warm cinnamon spice, a true old fashioned apple pie recipe your whole family will request again and again.

There is something magical about pulling a bubbling Granny Smith Apple Pie out of the oven. The tart green apples soften into a jammy, spiced filling while the crust turns golden and flaky, and the whole kitchen smells like cinnamon and warm butter. If you have been searching for a truly old fashioned apple pie recipe, one that tastes like it came straight from a grandmother's kitchen, this is it.
What makes this Granny Smith Apple Pie recipe stand out is the balance. Granny Smith apples are famously tart and firm, which means they hold their shape during baking instead of turning to mush, and they provide the perfect contrast to the sweet, buttery crust. This is not just another apple pie, it is the classic apple pie recipe that professional bakers reach for again and again.
Before we get cooking, the right tools and ingredients make a real difference here. A good pastry cutter helps you keep the butter cold and evenly distributed for a flaky crust, and a sturdy glass or ceramic pie dish promotes even browning on the bottom crust so it never turns soggy. A reliable digital thermometer or oven thermometer also helps make sure your oven is running true, since apple pie is unforgiving of underbaking.
When it comes to Green Apple Pie recipes, Granny Smith apples are the gold standard for a reason. Their firm texture and bright, tart flavor stand up beautifully to long baking times, and they release just the right amount of juice to create a filling that is thick and luscious rather than watery or runny.
Unlike sweeter varieties, Granny Smith apples also need very little help from sugar to shine. This lets the natural apple flavor come through, especially when paired with warm cinnamon and a touch of nutmeg.
Chef's Tip: Slice your apples to a consistent thickness, about a quarter inch, so they cook evenly. Uneven slices can leave you with a mix of mushy and undercooked pieces in the same pie.
A great apple pie lives and dies by its crust. The key to a flaky, tender crust is temperature control. Keep your butter, water, and even your mixing bowl cold, and work quickly so the butter does not melt into the flour before it hits the oven. Those little pockets of cold butter are what create steam during baking, which is what gives you those beautiful, flaky layers.
If you are short on time, a good quality store bought pie crust can work in a pinch, but a homemade crust truly elevates this into a showstopping dessert worth savoring.

This Granny Smith Apple Pie recipe delivers a flaky, buttery crust packed with tart, juicy green apples and warm cinnamon spice, a true old fashioned apple pie recipe your whole family will request again and again.
In a large bowl, whisk together the flour, 1 tablespoon sugar, and half the salt. Cut in the cold cubed butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea sized bits of butter.
Add ice water 1 tablespoon at a time, mixing gently until the dough just comes together. Divide the dough in half, shape into two discs, wrap in plastic, and chill for at least 1 hour.
Preheat the oven to 400 degrees F (200 degrees C). Place a baking sheet on the lower rack to catch any drips.
In a large bowl, toss the sliced Granny Smith apples with granulated sugar, brown sugar, cinnamon, nutmeg, remaining salt, lemon juice, and cornstarch until evenly coated. Let sit for 10 minutes.
On a lightly floured surface, roll out one dough disc into a 12 inch circle and fit it into a 9 inch pie dish, letting the excess hang over the edges.
Pour the apple filling into the crust, mounding it slightly in the center, and dot the top with the remaining butter.
Roll out the second dough disc and place it over the filling, or cut into strips for a lattice top. Trim excess dough and crimp the edges to seal.
Brush the top crust with the beaten egg wash and sprinkle with coarse sugar. Cut a few small slits in the top if using a solid crust to allow steam to escape.
Bake for 20 minutes at 400 degrees F, then reduce the oven temperature to 350 degrees F (175 degrees C) and continue baking for 30 to 35 minutes, until the crust is deep golden brown and the filling is bubbling.
If the edges brown too quickly, cover them loosely with foil or a pie shield partway through baking.
Cool the pie on a wire rack for at least 2 to 3 hours before slicing to allow the filling to set.
This pie is best served slightly warm, about 2 to 3 hours after baking, so the filling has time to set but the crust is still fresh. A scoop of vanilla ice cream or a dollop of freshly whipped cream turns it into an unforgettable dessert.
For storage, keep the cooled pie loosely covered at room temperature for up to two days, or refrigerate for longer freshness. To reheat, a few minutes in a moderate oven brings back that just baked crispness far better than a microwave ever could.

Chef's Tip: Always let the pie rest fully before slicing. Cutting into it too early causes the filling to run out, even if the flavor is perfect.
