This Granny Smith apple pie recipe bakes tart green apples in a buttery, flaky homemade crust for a classic, old fashioned dessert everyone will love.

There is something magical about a homemade Granny Smith apple pie fresh out of the oven. The filling bubbles up through golden lattice strips, the kitchen smells like cinnamon and warm butter, and that first slice practically demands a scoop of vanilla ice cream on the side. This is not a fussy recipe. It is a classic apple pie recipe built on tried and true technique, the kind your grandmother probably made without measuring a thing.
Granny Smith apples are the star here for good reason. Their tart, crisp bite holds up beautifully during baking, so you get a filling that is soft but never mushy, sweet but never cloying. If you have only ever used softer apples for pie, switching to green apples is going to change the way you think about this dessert forever.
Before we get cooking, the right tools and ingredients make a real difference here. A good pastry cutter and a sturdy glass pie dish take a lot of the guesswork out of building a flaky, evenly baked crust, and they are worth having on hand for every pie season to come.
When people search for the best apples for pie, Granny Smith almost always tops the list, and for good reason. Their firm flesh and high acidity mean they:
Chef's Tip: Slice your apples to a consistent thickness, about a quarter inch, so they cook evenly. Uneven slices mean some pieces turn to mush while others stay too firm.
A truly great green apple pie lives or dies by its crust. The secret to an old fashioned, flaky crust is temperature control. Cold butter, cold water, and a quick hand are everything. Overworking the dough develops too much gluten, which leads to a tough, chewy crust instead of the tender, shattering layers you want.
Work the butter into the flour just until you see pea sized crumbs, and stop mixing the moment the dough holds together when pinched. It should look a little shaggy, not smooth like bread dough. That shagginess is exactly what gives you those beautiful flaky layers once it hits the oven.
Tossing the sliced apples with sugar, flour, cinnamon, and lemon juice does double duty. The sugar draws out excess moisture, the flour thickens that liquid into a glossy, jammy sauce, and the lemon juice brightens everything while keeping the apples from browning as you work.
Letting the mixture rest for ten minutes before filling the crust is a small step that makes a real difference in the final texture of your Granny Smith apple pie.

This Granny Smith apple pie recipe bakes tart green apples in a buttery, flaky homemade crust for a classic, old fashioned dessert everyone will love.
In a large bowl, whisk together the flour, sugar, and salt for the crust. Cut in the cold cubed butter with a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea sized bits of butter.
Drizzle in the ice water a tablespoon at a time, mixing gently until the dough just comes together. Divide 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).
In a large bowl, toss the sliced Granny Smith apples with granulated sugar, brown sugar, flour, cinnamon, and lemon juice until evenly coated. Let sit for 10 minutes.
Roll out one dough disc on a lightly floured surface and fit it into a 9 inch pie dish, trimming any excess overhang.
Pour the apple filling into the crust, mounding it slightly in the center.
Roll out the second disc and place it over the filling, or cut it into strips for a lattice top. Trim and crimp the edges to seal.
Brush the top crust with beaten egg and sprinkle generously with turbinado sugar. Cut a few small slits in the top if using a solid crust.
Place the pie on a baking sheet to catch any drips and bake for 20 minutes at 400 degrees F.
Reduce the oven temperature to 350 degrees F (175 degrees C) and continue baking for 30 to 35 minutes, until the crust is golden and the filling is bubbling.
If the edges brown too quickly, cover them loosely with foil.
Cool the pie on a wire rack for at least 3 hours before slicing to allow the filling to set.
This apple pie recipe homemade from scratch is best served warm, about 3 to 4 hours after it comes out of the oven, once the filling has had time to set. A slightly warm slice with a scoop of vanilla ice cream or a dollop of freshly whipped cream is hard to beat.
If you are getting ahead for a holiday or gathering, you have options. You can:
Chef's Tip: If your crust edges are browning faster than the center is cooking, loosely tent them with foil for the last 20 minutes of baking. This keeps everything golden without burning.
However you serve it, this Granny Smith apple pie recipe delivers that nostalgic, old fashioned flavor every single time. Once you taste how well tart green apples work in this classic dessert, it may just become your go to version for good.
