Home-baked Apple Slab Pie Recipe

Home-baked Apple Slab Pie Recipe tastes like a bakery-style apple pie with buttery, flaky crust and jammy, cinnamon apples in every single bite. It works perfectly for holidays, potlucks, or weeknight cravings and takes about 2 hours start to finish, including chill time. I grew up in a small Midwestern town, and this kind of big-batch pie still feels like a hug from my grandma’s kitchen.

Why Home-baked Apple Slab Pie Recipe Is Worth It

This slab pie feeds a crowd without any fussy lattice work or tiny pie tins. You roll one big crust, pile on the apples, top it, and slice into neat squares that stack easily on a dessert tray.

The crust stays sturdy enough to hold in your hand, yet still tastes tender and flaky. The filling cooks into soft, saucy apples with warm spices that make your kitchen smell like a fall festival.

Ingredients You Need

For the crust

You can use a good-quality store-bought refrigerated pie crust if you feel short on time, but a homemade crust tastes incredible in a slab pie.

• 3 cups all-purpose flour
• 1 tablespoon granulated sugar
• 1 teaspoon fine sea salt
• 1 cup (2 sticks) cold unsalted butter, cut into small cubes
• 1 large egg
• 1/2 cup ice-cold water, plus 1 to 2 tablespoons more as needed
• 1 teaspoon apple cider vinegar or white vinegar

You can swap in half whole wheat flour for a slightly nutty flavor, but add 1 to 2 extra tablespoons of water since whole wheat flour absorbs more liquid.

For the apple filling

Choose a mix of tart and sweet apples for best flavor and texture. I like Granny Smith for tart crunch and Honeycrisp or Fuji for sweetness.

• 10 to 12 medium apples, peeled, cored, and sliced thin
  • Aim for about 3 1/2 to 4 pounds total sliced apples
• 3/4 cup granulated sugar
• 1/4 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
• 2 teaspoons lemon juice
• 1 teaspoon vanilla extract

You can use all brown sugar if you like deeper caramel flavor. If your apples taste very tart, bump the sugar up by 2 to 3 tablespoons.

For assembly and finish

• 1 large egg, beaten with 1 tablespoon milk or cream, for egg wash
• 1 to 2 tablespoons coarse sugar or turbinado sugar, for sprinkling
• Optional: 1 tablespoon melted butter to brush on crust edges after baking

Simple vanilla glaze (optional)

• 1 cup powdered sugar, sifted
• 2 to 3 tablespoons milk or cream
• 1/2 teaspoon vanilla extract
• Pinch of salt

Whisk until smooth and pourable. Add more milk by the teaspoon if it looks too thick.

Equipment list

• 13 x 18 inch rimmed baking sheet (standard half sheet pan)
• Parchment paper
• Rolling pin
• Large mixing bowls
• Measuring cups and spoons
• Pastry cutter or food processor for crust
• Sharp knife or mandoline for slicing apples
• Pastry brush
• Cooling rack

Quick Tips & substitutions

• Use a mix of apples so the filling tastes complex and not flat.
• Slice apples evenly so they cook at the same rate and avoid crunchy surprises.
• Chill the crust dough at least 45 minutes so it rolls easily and bakes flaky.
• Dust your counter lightly with flour and rotate the dough often so it does not stick.
• Swap store-bought pie crust sheets if you feel short on time, and just trim to fit the pan.
• Use cornstarch instead of flour in the filling if you want a clearer, glossy sauce.
• Add a pinch more salt to the crust if you use salted butter and skip extra salt.
• Use plant-based butter sticks and non-dairy milk for an easy dairy-free version.
• Line the pan with parchment so you lift the whole slab out for clean cutting.
• Cool the pie at least 45 minutes so the filling sets and slices hold their shape.

How to Make Home-baked Apple Slab Pie Recipe

Mix the crust dough

1. Add flour, sugar, and salt to a large bowl and whisk to combine.

2. Toss in the cold butter cubes and cut them into the flour with a pastry cutter or your fingertips until you see pea-size bits of butter.

3. Beat the egg with the cold water and vinegar, then drizzle it over the flour mixture.

4. Stir gently with a fork until the dough starts to clump together, then use your hands to press it into a shaggy ball.

5. If the dough looks dry and crumbly, sprinkle in 1 tablespoon more cold water at a time until it holds together.

6. Divide the dough into two pieces, one slightly larger than the other, and shape each into a rectangle.

7. Wrap both pieces tightly in plastic wrap and chill in the fridge for at least 45 minutes and up to 2 days.

Prep the apples

1. Peel, core, and slice the apples into thin slices, about 1/4 inch thick.
2. Place the slices in a large bowl and drizzle with lemon juice to keep them bright.
3. Add granulated sugar, brown sugar, flour or cornstarch, cinnamon, nutmeg, allspice, salt, and vanilla.
4. Toss until every slice looks coated and glossy, then set the bowl aside while you roll the crust.

Roll out the bottom crust

1. Line your baking sheet with parchment paper and let some overhang on the long sides for easy lifting.

2. Take the larger piece of dough out of the fridge and let it sit on the counter for 5 minutes so it softens slightly.

3. On a lightly floured surface, roll the dough into a large rectangle, about 18 x 13 inches, to fit the pan with a little overhang.

4. Gently roll the dough around the rolling pin and unroll it over the prepared pan.

5. Press the dough into the corners and sides of the pan without stretching it.

6. Let the edges hang over the rim slightly, and trim any wild edges with a sharp knife or kitchen scissors.

Fill with apple mixture

1. Give the apple mixture a quick toss again, since the juices settle at the bottom.
2. Pour the apples into the crust-lined pan and spread them into an even layer.
3. Scrape every bit of the sugary juices from the bowl over the apples, since that liquid turns into sauce.
4. Try to keep the apples in a mostly level layer so the top crust bakes evenly.

Roll out the top crust

1. Take the second piece of dough from the fridge and let it sit for 5 minutes.

2. Roll it into a rectangle just a bit smaller than the pan, about 17 x 12 inches.

3. Carefully roll the dough around the rolling pin and unroll it over the apples.

4. Tuck the top crust edges under the bottom crust edges all around the pan and pinch to seal.

5. Crimp the edges with your fingers or a fork for a simple border.

6. Use a sharp knife to cut several small slits across the top crust so steam can escape.

Add egg wash and sugar

1. Whisk the egg and milk together in a small bowl.
2. Brush the egg wash lightly over the entire top crust and edges.
3. Sprinkle coarse sugar over the top for crunch and sparkle.

Bake the slab pie

1. Heat your oven to 400°F and place a rack in the center.
2. Slide the pan into the oven and bake at 400°F for 20 minutes.
3. Lower the heat to 350°F and continue baking for 30 to 35 minutes, until the crust looks deep golden and the filling bubbles through the slits.
4. If the edges brown too fast, tent them loosely with strips of foil and keep baking.

Cool and glaze

1. Place the pan on a cooling rack and let the pie cool at least 45 to 60 minutes.
2. If you use glaze, whisk powdered sugar, milk, vanilla, and a pinch of salt until smooth.
3. Drizzle the glaze over the slightly warm pie in thin zigzags.
4. Cool completely for neat squares, or cut while still a little warm if you feel okay with softer slices.

Slice and serve

1. Use the parchment to lift the slab pie from the pan onto a cutting board.
2. Cut into 12 large pieces for generous servings or 24 smaller squares for parties.
3. Wipe the knife between cuts for clean edges, especially if you use glaze.

Recipe Variations

• Gluten-free: Use a 1 to 1 gluten-free baking flour in the crust and cornstarch in the filling.
• Vegan: Use plant-based butter sticks, skip the egg in the crust, add 2 to 3 extra tablespoons cold water, and brush the top with non-dairy milk instead of egg wash.
• Low sugar: Reduce sugar in the filling by one third and use very sweet apples like Fuji or Gala.
• Low carb style: Use a low carb sweetener that measures like sugar and thicken with a small amount of xanthan gum instead of flour.
• Extra spice: Add cardamom or ginger to the filling for a cozy twist.
• Caramel apple: Drizzle a few tablespoons of thick caramel sauce over the apples before you add the top crust.
• Crumble top: Skip the top crust and use a simple oat streusel for a hybrid pie and crisp situation.

Ways to Serve Home-baked Apple Slab Pie Recipe

• Serve warm with a scoop of vanilla ice cream.
• Offer it at room temperature with a dollop of whipped cream.
• Pack chilled squares in lunchboxes as a sweet treat.
• Top with a spoonful of Greek yogurt for a dessert-meets-breakfast vibe.
• Cut into tiny squares and arrange on a platter for a dessert buffet.

Storage Success

Let the Home-baked Apple Slab Pie Recipe cool completely, then cover the pan tightly with foil or transfer slices to an airtight container. Store at room temperature for up to 2 days, or keep in the fridge for up to 5 days. Reheat slices in a 325°F oven for about 10 minutes so the crust turns crisp again and the apples warm through. Freeze individual slices wrapped in plastic and tucked in a freezer bag for up to 2 months, then thaw in the fridge and warm in the oven before serving.
