Introduction
Glazed apple slab pie is a simple yet elegant dessert that combines the flaky layers of puff pastry with the sweet-tart flavors of spiced apples.
Baked in a sheet pan rather than a traditional pie dish, it’s perfect for serving a crowd at gatherings, holidays, or any cozy family night. The finishing touch—a sweet vanilla glaze—adds shine and extra indulgence.
Ingredients
For the pie
2 sheets puff pastry (thawed) or homemade pie crust
5 cups thinly sliced apples (Granny Smith or Honeycrisp work well)
½ cup granulated sugar
2 tbsp all-purpose flour
1 tsp ground cinnamon
¼ tsp ground nutmeg
1 tsp vanilla extract
1 tbsp lemon juice
1 tbsp butter, cut into small cubes
1 egg (beaten with 1 tbsp water, for egg wash)
For the glaze
1 cup powdered sugar
2–3 tbsp milk (or cream for richer flavor)
½ tsp vanilla extract
Instructions
Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper. Roll out one sheet of puff pastry and place it on the sheet pan.
In a large bowl, toss together the apples, sugar, flour, cinnamon, nutmeg, vanilla, and lemon juice until the slices are evenly coated.
Spread the apple mixture over the pastry, leaving a small border around the edges. Dot with butter cubes.
Place the second sheet of pastry over the top, sealing the edges by pressing with a fork. Brush the top with egg wash and cut a few small slits to allow steam to escape.
Bake for 30–35 minutes, or until golden brown and flaky. Let cool slightly.
In a small bowl, whisk together powdered sugar, milk, and vanilla until smooth. Drizzle over the cooled pie before slicing into squares.
How to Make
The key to making a perfect glazed apple slab pie is preparing the apples evenly so they cook at the same rate.
Coat them thoroughly with sugar, spices, and lemon juice to balance flavor and prevent browning.
Sealing the pastry edges well ensures the filling stays inside, while cutting slits on top allows steam to escape for a crisp finish.
The glaze should be drizzled only after the pie cools, so it doesn’t melt away.
Variations
You can try mixing different apple varieties for a more complex flavor. Add chopped pecans or walnuts for crunch, or a handful of raisins or cranberries for extra sweetness.
Swap puff pastry for traditional pie crust if you prefer a denser base. For a caramel twist, drizzle warm caramel sauce instead of the vanilla glaze.
Tips
Make sure the puff pastry is thawed but still cold before baking to ensure maximum flakiness.
Don’t skip the lemon juice—it brightens the filling and prevents apples from turning brown. If you like your pie less sweet.
reduce the sugar slightly or balance it with more tart apples. For a glossy finish, always brush with egg wash before baking.
Conclusion
Glazed apple slab pie is a delightful dessert that’s easier to make than a traditional pie but just as impressive.
With its flaky crust, spiced apple filling, and sweet drizzle on top, it strikes the perfect balance between comforting and festive.
Serve it warm or at room temperature, and watch it disappear quickly from the table.
