Home-baked Apple Slab Pie Recipe tastes like a cross between a classic apple pie and a bakery-style apple pastry, with buttery crust, soft spiced apples, and a light vanilla glaze on top. It works perfectly for holidays, potlucks, school events, or any time you want pie for a crowd in about 1 hour 30 minutes total. I baked a version of this for my kid’s soccer team once, and the parents attacked it faster than the kids attacked the orange slices.

Ingredients You’ll Need
You can use a half sheet pan or a 10×15 inch jelly roll pan for this Home-baked Apple Slab Pie Recipe. I like a light-colored metal pan, since dark pans brown the crust faster.
For the crust
You can use homemade crust or store-bought refrigerated pie crust sheets. I share both options, because life happens.
Homemade crust (for a 10×15 inch slab pie):
- 3 1/4 cups all-purpose flour
- 1 tablespoon granulated sugar
- 1 1/2 teaspoons fine sea salt
- 1 1/4 cups cold unsalted butter, cut into small cubes
- 3/4 to 1 cup ice water, as needed
- 1 teaspoon apple cider vinegar or white vinegar (helps keep the crust tender)
Shortcut option:
- 3 refrigerated pie crusts, rolled slightly thinner and patched together to fit the pan
- I like Pillsbury or a similar national brand, since they roll easily and stay flaky.
For the apple filling
- 8 to 9 cups peeled, cored, thinly sliced apples
- Use a mix of tart and sweet apples: Granny Smith, Honeycrisp, Pink Lady, or Fuji.
- 3/4 to 1 cup granulated sugar, to taste and apple sweetness
- 1/3 cup light brown sugar, packed
- 1/4 cup all-purpose flour or 3 tablespoons cornstarch
- 1 1/2 teaspoons ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon ground allspice (optional but tasty)
- 1/4 teaspoon fine sea salt
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
Substitution notes:
- Use all granulated sugar if you do not have brown sugar.
- Swap pumpkin pie spice for the cinnamon, nutmeg, and allspice if you want a shortcut.
- Use cornstarch instead of flour if you prefer a clearer, slightly glossier filling.
For assembly
- 1 egg, beaten with 1 tablespoon milk or cream (for egg wash)
- 1 to 2 tablespoons coarse sugar or regular sugar for sprinkling on top
Optional vanilla glaze
- 1 cup powdered sugar
- 2 to 3 tablespoons milk or cream
- 1 teaspoon vanilla extract
- Pinch of salt
Whisk until smooth and pourable. Add more milk by teaspoons if it feels too thick.
Equipment list
- 10×15 inch jelly roll pan or similar rimmed baking sheet
- Rolling pin
- Large mixing bowl
- Small bowl for egg wash
- Measuring cups and spoons
- Sharp knife or apple slicer
- Pastry brush
- Cooling rack
- Parchment paper (helps with easy cleanup and slicing)
Tips & Tricks
- Chill the crust ingredients and keep the butter cold, since cold fat gives you flaky layers.
- Slice apples evenly so they cook at the same rate and stay tender, not mushy.
- Taste a slice of apple with sugar and spices before you fill the crust, then adjust sweetness.
- Vent the top crust with slits or small shapes so steam escapes and the bottom crust stays crisp.
- Bake the slab pie on the lower-middle oven rack to help the bottom crust brown.
- Line the pan with parchment and leave a little overhang to lift slices easily.
- Let the pie cool at least 30 to 45 minutes before slicing so the filling sets.
- Add glaze only after the slab pie cools to warm or room temperature, or the glaze will slide off.
- Use store-bought crust when you feel short on time, and focus your energy on the filling.
- Reheat slices in the oven or toaster oven, not the microwave, to keep the crust crisp.
How to Make Home-baked Apple Slab Pie Recipe
Step 1: Mix the crust
Stir the flour, sugar, and salt in a large bowl. Add the cold butter cubes and cut them into the flour with a pastry cutter or your fingers until you see pea-size bits of butter. Drizzle in 3/4 cup ice water and vinegar, then mix gently until the dough holds together when you squeeze it.
Add more water a tablespoon at a time if the dough feels dry. Divide the dough into two pieces, one slightly larger for the bottom crust. Shape each piece into a rectangle, wrap in plastic, and chill at least 1 hour.
Step 2: Prep the apples
Peel, core, and slice the apples into thin slices, about 1/4 inch thick. Place them in a large bowl. Add granulated sugar, brown sugar, flour or cornstarch, cinnamon, nutmeg, allspice, salt, lemon juice, and vanilla.
Toss until the apples look evenly coated and no dry pockets of flour remain. Taste a slice and adjust sugar or spices if needed. Let the apples sit while you roll the crust so the juices start to release.
Step 3: Roll out the bottom crust
Preheat the oven to 400°F. Line your jelly roll pan with parchment and lightly flour it. On a lightly floured surface, roll the larger piece of dough into a rectangle slightly bigger than your pan.
Lift the dough gently and place it in the pan, pressing it into the corners and up the sides. Trim any big overhangs, but leave about 1/2 inch to help seal the top crust later. Chill the pan with the bottom crust while you roll the top.
Step 4: Roll out the top crust
Roll the second piece of dough into another rectangle that fits the top of the pan. You can cut strips for a lattice or keep it as one solid sheet. If you choose a solid sheet, plan a few slits or cut small shapes for vents.
Transfer the rolled top crust to a parchment-lined baking sheet and chill it while you fill the bottom crust. Cold dough handles more easily and bakes flakier.
Step 5: Fill the slab pie
Give the apples a quick toss again, then pour them into the prepared bottom crust. Spread them into an even layer, all the way to the corners. Scrape any juices from the bowl over the apples.
Place the top crust over the apples. Fold the bottom crust edges up and over the top crust edges and pinch to seal. Crimp the edges with your fingers or a fork.
Step 6: Add vents and egg wash
Cut several slits in the top crust if you use a solid sheet. This step lets steam escape and helps the filling thicken instead of bubbling out everywhere. Brush the top crust with the egg wash.
Sprinkle sugar over the top for sparkle and crunch. Place the pan on a larger baking sheet if you worry about drips.
Step 7: Bake the slab pie
Bake at 400°F for 20 minutes. Reduce the oven temperature to 350°F and continue baking 25 to 35 minutes, until the crust looks golden and the filling bubbles through the vents. If the edges brown too fast, cover them loosely with strips of foil.
Check the bottom crust by lifting a corner of the slab pie gently with a spatula. It should look golden, not pale. If it still looks light, bake another 5 to 10 minutes.
Step 8: Cool and glaze
Place the pan on a cooling rack and let the slab pie cool at least 30 to 45 minutes. This rest time helps the filling thicken so slices hold their shape. While it cools, whisk the powdered sugar, milk, vanilla, and salt until smooth.
Drizzle the glaze over the slightly warm or room temperature slab pie in thin lines or zigzags. Let the glaze set for about 10 minutes. Slice into squares and serve.
What to Serve with Home-baked Apple Slab Pie Recipe
This Home-baked Apple Slab Pie Recipe pairs beautifully with vanilla ice cream, cinnamon ice cream, or a scoop of frozen yogurt. A dollop of lightly sweetened whipped cream also tastes amazing and keeps things simple. Serve it with hot coffee, chai, or spiced black tea for adults, and warm apple cider or cold milk for kids.
You can also add a side of fresh fruit, like berries or sliced pears, to balance the richness. If you serve it at brunch, pair it with scrambled eggs and a simple green salad to round out the meal.
Storage Options
- Store leftover slab pie covered at room temperature for up to 1 day if your kitchen stays cool.
- Keep slices in an airtight container in the fridge for 3 to 4 days.
- Freeze individual slices wrapped tightly in plastic, then in a freezer bag, for up to 2 months.
- Reheat slices in a 325°F oven or toaster oven for 10 to 15 minutes until warm and crisp again.
- Avoid reheating in the microwave when possible, since it softens the crust and turns it soggy.
