Save to Pinterest This generous apple slab pie bakes in a large rectangular pan, making it perfect for feeding crowds at family gatherings and celebrations. The double-crust pastry encases layers of tart and sweet apples tossed with warm cinnamon and nutmeg, creating a beautifully spiced filling. The golden crust gets a lovely shine from an egg wash and optional sugar sprinkling.
Slice into squares for easy serving—warm with vanilla ice cream or at room temperature. The rectangular shape yields more servings than traditional round pies while maintaining that classic homemade taste everyone loves.
Last Thanksgiving, my kitchen became a temporary assembly line when my sister suggested we make slab pie instead of the usual round ones. The smell of cinnamon and butter filled every corner of the house while we peeled and sliced what felt like a mountain of apples.
My niece declared it the best dessert shed ever had, going back for thirds before dinner was even served. Something about those rustic slab squares just makes people feel at home.
Ingredients
- All purpose flour: The foundation of a sturdy yet tender crust that holds up to all those apple juices
- Cold unsalted butter: Keep it ice cold and cut into cubes before you start working it into the flour
- Ice water: Add it gradually and stop as soon as the dough comes together
- Mix of apple varieties: Granny Smith for tartness and structure, Honeycrisp for sweetness and crunch
- Both granulated and brown sugar: The combination creates depth of flavor in the filling
- Cornstarch: This thickens the apple juices so you dont end up with a soggy bottom crust
- Egg wash: Gives the top crust that beautiful golden bakery shine
Instructions
- Make the pie dough:
- Work quickly and keep everything cold. The butter should remain in visible pea sized pieces throughout the process.
- Prepare your pan:
- Lining with parchment paper makes cleanup so much easier and helps you lift the whole pie out later if you want.
- Roll out the bottom crust:
- Dont worry if it tears slightly. Patch it right back together and keep going.
- Mix the apple filling:
- Toss everything thoroughly so every apple slice gets coated in that spiced sugar mixture.
- Assemble the pie:
- Spread the apples evenly and dont be afraid to mound them slightly higher in the center.
- Seal the top crust:
- Pinch the edges tightly together so none of those delicious juices escape during baking.
- Add the egg wash:
- Brush it on gently but thoroughly for that gorgeous golden finish.
- Bake until golden:
- The filling should be actively bubbling through the steam vents when its done.
Save to Pinterest The first time I made this for a potluck, someone asked for the recipe before even taking a bite. The way the sunlight hit that golden sugar topping was practically magnetic.
Choosing Your Apples
After years of experimenting, I have found that a mix of at least two apple varieties gives the best results. Some apples break down into sauce while others hold their shape, and having both textures in one pie is pure magic.
Working With Slab Pie Dough
The larger surface area means this dough needs to be rolled thinner than a standard pie crust. Work from the center out and rotate your dough frequently to keep it even. If it becomes too soft and stubborn, pop it in the refrigerator for 10 minutes.
Storage And Serving
This pie keeps beautifully at room temperature for up to two days, covered loosely with foil. The flavors actually develop more depth on the second day. To reheat, pop individual squares in a 350 degree oven for about 8 minutes.
- Serve with vanilla ice cream while still slightly warm
- A pinch of flaky sea sugar on top elevates everything
- Store any leftovers in the refrigerator after day two
Save to Pinterest There is something wonderfully casual about slab pie that makes any gathering feel like a celebration. I hope this recipe finds its way into your regular rotation.
