Save to Pinterest This slab pie delivers all the comfort of traditional apple pie in a format perfect for feeding a crowd. The flaky, buttery crust envelopes tender slices of Granny Smith and Honeycrisp apples tossed with warming cinnamon and nutmeg. Baked in a large rimmed sheet pan, it yields neatly portioned squares that are easier to serve than wedge slices. The golden finish comes from an egg wash, with optional coarse sugar adding delightful crunch. Serve warm with vanilla ice cream or at room temperature for potlucks and holiday gatherings.
The sheer size of a slab pie changes everything about serving dessert at gatherings. I discovered this one Thanksgiving when my round pie pans refused to accommodate the hungry crowd. There is something deeply satisfying about sliding that enormous golden rectangle onto the table and watching faces light up.
My neighbor actually asked for the recipe before she even finished her first square. She said it reminded her of the school cafeteria pies we all loved as kids but elevated. That moment made me realize sometimes the most nostalgic desserts are the ones that feed the most people.
Ingredients
- All-purpose flour: The structure that holds everything together
- Cold unsalted butter: Those cold bits create flaky layers
- Ice water: Keep it icy to prevent the butter from softening
- Granny Smith and Honeycrisp apples: A mix gives you the perfect balance of tart and sweet
- Both granulated and brown sugar: The brown sugar adds depth and caramel notes
- Cornstarch: This thickens all those apple juices so your bottom crust stays crisp
- Egg wash: That professional bakery shine that makes people think you slaved for hours
Instructions
- Make the dough:
- Work quickly and keep those butter bits cold. The dough should just come together without being overworked or tough.
- Prep your pan:
- A rimmed baking sheet is essential here. The juices will bubble up and you want those edges contained.
- Roll the bottom crust:
- Dont worry if it tears. Patch it right up because no one will see under all those apples.
- Mix the filling:
- Get your hands in there and toss everything thoroughly. Every apple slice needs that spiced sugar coating.
- Assemble:
- Layer those apples like shingles. This dense packing prevents that dreaded gap between crust and filling.
- Top and seal:
- Crimp edges like your life depends on it. This keeps all that glorious filling inside where it belongs.
- Give it some shine:
- Brush the egg wash everywhere. This is what creates that beautiful golden color we all want.
- Bake until bubbly:
- Trust your nose. When that cinnamon fills the kitchen and the crust is deep golden, it is done.
- The hardest part:
- Let it cool for at least 30 minutes. Cutting into hot pie gives you a runny mess but patience yields perfect squares.
Save to Pinterest Last Christmas my sister-in-law brought store-bought pies and nobody touched them after seeing this slab. There is something about rustic home baking that draws people in. The next morning we ate cold squares for breakfast with coffee.
Choosing Your Apples
I have tested countless combinations and found that mixing tart Granny Smiths with sweet Honeycrisps creates the most complex flavor profile. The tart apples hold their shape while the sweet ones break down slightly creating that perfect sauce. Pink Lady and Jonagold work beautifully too.
Making Ahead
The dough can be made and refrigerated up to two days before baking. You can even fully assemble the pie and freeze it unbaked. Add about ten minutes to the baking time if baking from frozen. Just do not egg wash until right before it goes in the oven.
Serving Suggestions
Warm squares with vanilla ice cream are divine but do not overlook whipped cream. A drizzle of salted caramel takes it over the top. For breakfast the next day, cold pie with black coffee is surprisingly wonderful.
- Sprinkle flaky sea salt on top before serving
- Add a handful of cranberries to the apple mix for holiday color
- Cut into smaller squares for cocktail party portions
Save to Pinterest This recipe turns ordinary apples into something people will talk about long after the last crumb is gone. Enjoy every moment of the process and the praise that follows.
Recipe Questions & Answers
- → What makes slab pie different from regular pie?
-
Slab pie is baked in a large rimmed baking sheet rather than a round pie dish. This creates a rectangular shape that yields more servings and cuts into convenient squares, making it ideal for feeding crowds and easy portioning at gatherings.
- → Which apple varieties work best?
-
Granny Smith apples provide tartness and hold their shape during baking, while Honeycrisp adds natural sweetness. A mix of both creates balanced flavor and texture. You can also include Braeburn or Jonagold for complexity.
- → Can I prepare the dough ahead of time?
-
Yes, the dough can be made up to 2 days in advance and stored wrapped tightly in the refrigerator. You can also freeze the dough for up to 3 months. Thaw overnight in the refrigerator before rolling out.
- → How should I store leftovers?
-
Keep covered at room temperature for up to 2 days. For longer storage, refrigerate in an airtight container for up to 5 days. The crust may soften slightly over time but reheating in a 350°F oven for 10 minutes helps restore crispness.
- → Can I freeze this slab pie?
-
Bake and cool completely, then wrap tightly in plastic and foil before freezing for up to 3 months. Thaw overnight in the refrigerator and reheat at 350°F for 15-20 minutes. You can also freeze the unbaked assembled pie; add 10-15 minutes to baking time.
- → Why does my crust shrink during baking?
-
Shrinking occurs when dough is stretched too thin or doesn't rest before baking. Roll dough evenly without overworking, and chill for 15 minutes after fitting it in the pan. This helps relax the gluten and prevent shrinkage.
