Home-baked Apple Slab Pie Recipe

Home-baked Apple Slab Pie Recipe tastes like a cross between a classic apple pie and a bakery-style pastry bar, with buttery crust, soft spiced apples, and a light crunch of sugar on top. It works perfectly for holidays, potlucks, bake sales, or any crowd, and you can finish it in about 2 hours including cooling time. I grew up in a small Midwest town, and this kind of big-batch pie always meant someone you loved walked into the kitchen with a sheet pan and good intentions.

Why Make This Home-baked Apple Slab Pie Recipe at Home

A slab pie feeds a crowd without the stress of multiple pies, and it slices into neat squares that travel easily. You use one big sheet pan, one big crust, and one big batch of filling, so the process feels simple and efficient.

This Home-baked Apple Slab Pie Recipe also gives you a higher crust-to-filling ratio, which crust lovers celebrate. You control the sweetness, the spice level, and the type of apples, so the flavor matches your exact pie personality.

Ingredients You Need

For the slab pie crust

You can use homemade crust or a smart shortcut with store-bought refrigerated pie dough. I list both.

• 3 3/4 cups (470 g) all-purpose flour
• 1 tablespoon granulated sugar
• 1 1/2 teaspoons fine sea salt
• 1 1/2 cups (340 g) cold unsalted butter, cut into small cubes
• 3/4 to 1 cup ice water, as needed
• 1 tablespoon apple cider vinegar or white vinegar (helps keep crust tender)

Shortcut option:

• 3 boxes refrigerated pie crust (like Pillsbury), at room temp just until pliable, not warm

For the apple filling

Choose a mix of tart and sweet apples for the best flavor and texture.

• 4 pounds apples, peeled, cored, and sliced about 1/4 inch thick
  • Great combo: half Granny Smith, half Honeycrisp or Fuji
• 3/4 to 1 cup granulated sugar, to taste
• 1/3 cup light brown sugar, packed
• 1/4 cup all-purpose flour
• 2 tablespoons cornstarch (helps prevent a soupy filling)
• 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
• 2 teaspoons lemon juice
• 1 teaspoon vanilla extract

For the topping

• 1 large egg
• 1 tablespoon milk or heavy cream
• 2 to 3 tablespoons coarse sugar or turbinado sugar for sprinkling

Equipment list

• 1 rimmed baking sheet, about 13 x 18 inches (standard half sheet pan)
• Parchment paper
• Rolling pin
• Large mixing bowls
• Measuring cups and spoons
• Sharp knife or mandoline for slicing apples
• Pastry brush
• Cooling rack

Tips & Mistakes

• Chill the butter and water very well so the crust bakes flaky, not tough.
• Avoid overworking the dough, since too much handling turns the crust dense and chewy.
• Slice apples evenly so they cook at the same rate and keep a nice bite.
• Taste a slice of apple with sugar and spice before baking so you adjust sweetness and cinnamon to your liking.
• Vent the top crust with slits so steam escapes and the filling does not bubble over too aggressively.
• Place the sheet pan on a larger pan or line the oven rack with foil to catch any drips and keep cleanup easy.
• Cool the slab pie until the juices thicken, or the slices will slide apart when you cut them.
• Use a sharp knife or bench scraper to cut squares so the crust edges stay neat and pretty.

How to Make Home-baked Apple Slab Pie Recipe

Make the crust

1. Add flour, sugar, and salt to a large bowl and whisk to combine. Toss in the cold butter cubes and coat them with flour.
2. Cut the butter into the flour with a pastry cutter or your fingertips until you see pea-size bits of butter with some larger flat pieces. Keep some visible butter chunks so the crust bakes flaky.
3. Stir the vinegar into 3/4 cup ice water. Drizzle the water into the flour mixture a little at a time, tossing with a fork until the dough holds together when you squeeze a handful.
4. Add a bit more water if the dough feels dry, but stop as soon as it clumps. Divide the dough into two pieces, one slightly larger for the bottom crust.
5. Shape each piece into a rectangle, wrap tightly in plastic, and chill at least 1 hour. You can chill it up to 2 days or freeze it for a month.

Prep the apples

1. Peel, core, and slice the apples about 1/4 inch thick. Keep the slices similar in size so they bake evenly.
2. Place the apples in a large bowl. Add granulated sugar, brown sugar, flour, cornstarch, cinnamon, nutmeg, allspice, salt, lemon juice, and vanilla.
3. Toss until every slice looks coated and glossy. Set the bowl aside while you roll the crust so the apples start to release some juice.

Roll out the bottom crust

1. Line the sheet pan with parchment paper. Lightly flour your counter and rolling pin.
2. Roll the larger piece of dough into a rectangle slightly bigger than your sheet pan, about 19 x 14 inches. Turn the dough often and dust with a little flour so it does not stick.
3. Gently roll the dough around the rolling pin and unroll it over the pan. Press it into the corners and up the sides, letting extra dough hang over the edges.

Shortcut with store-bought crust:

1. Unroll the pie crusts and lightly roll them together to form a large rectangle. Press and pinch seams together where they meet.
2. Fit the dough into the lined sheet pan, patching any thin spots with extra dough.

Fill the slab pie

1. Give the apple mixture a quick stir. Pour the apples and all the juices into the crust-lined pan.
2. Spread the apples into an even layer, right into the corners. Keep the layer fairly level so the top crust sits nicely.

Roll out the top crust

1. Roll the second piece of dough into a rectangle slightly larger than the sheet pan. Keep it about the same thickness as the bottom crust.
2. Lift the dough with the rolling pin and unroll it over the apples. Let it drape over the edges.
3. Trim excess dough so you have about 1/2 inch overhang all around. Fold the top and bottom crust edges together and crimp them to seal.

Vent and egg wash

1. Use a sharp knife to cut several slits across the top crust so steam escapes. You can cut simple lines or a loose crosshatch pattern.
2. Beat the egg with the milk or cream in a small bowl. Brush the egg wash over the top crust and edges.
3. Sprinkle coarse sugar evenly over the top for crunch and sparkle.

Bake the slab pie

1. Heat the oven to 400°F (200°C). Place the sheet pan on the middle rack.
2. Bake 25 minutes, then lower the heat to 375°F (190°C). Continue baking 20 to 30 minutes, until the crust looks deep golden and the filling bubbles through the slits.
3. If the edges brown too quickly, shield them with strips of foil. Keep the pie in the oven until you see steady bubbling so the filling thickens properly.

Cool and slice

1. Place the baked slab pie on a cooling rack. Let it cool at least 45 to 60 minutes so the juices set.
2. Slice into squares or rectangles with a sharp knife. Wipe the knife between cuts for clean edges.
3. Serve warm or at room temperature, plain or with toppings.

Variations I've Tried

• Caramel apple slab pie: Drizzle 1/3 cup thick caramel sauce over the apples before you add the top crust, and cut the sugar in the filling by a couple of tablespoons.
• Crumble-topped slab pie: Skip the top crust and use a streusel topping with flour, brown sugar, cold butter, and oats. Bake until the topping turns golden and crisp.
• Maple cinnamon slab pie: Replace half the granulated sugar with pure maple syrup and bump the cinnamon up by an extra 1/2 teaspoon. The maple flavor plays really well with tart apples.
• Apple cranberry slab pie: Add 1 to 1 1/2 cups fresh or thawed frozen cranberries to the apples and increase the sugar by 2 to 3 tablespoons. The cranberries add bright color and a tangy bite.

How to Serve Home-baked Apple Slab Pie Recipe

Serve this Home-baked Apple Slab Pie Recipe slightly warm so the crust stays crisp and the filling feels cozy but not runny. Add a scoop of vanilla ice cream, cinnamon ice cream, or a spoonful of whipped cream on top. Pair slices with hot coffee, black tea, spiced chai, or cold milk for kids and grownups. Cut small squares for lunchboxes or bake sale trays, and cut larger rectangles when you want a full dessert plate situation.

How to store

• Room temperature: Keep the slab pie loosely covered at room temp for up to 24 hours if your kitchen stays cool.
• Fridge: Store leftovers in an airtight container or cover the pan tightly and refrigerate up to 4 days.
• Freezer (whole or sliced): Wrap the cooled pie or individual squares in plastic, then foil, and freeze up to 2 months.
• Reheat slices: Warm slices in a 325°F (165°C) oven or toaster oven for 8 to 12 minutes until the crust crisps and the center heats through.
• Reheat a whole slab: Cover loosely with foil and heat at 325°F (165°C) for 20 to 30 minutes, then uncover for a few minutes to refresh the top crust.
