What Is an Apple Slab Pie?
A slab pie is your favorite dessert, but bigger—same ingredients, baked flat in a rectangular pan. You get more crust, easy cutting, and a dessert that travels well. Skip delicate edges or crimping: roll the dough into a rectangle, spread the apples, and cover with another pastry layer.
Making one slab pie is simpler than baking multiple pies. Each square balances crisp edges, juicy apples, and sweetness. It’s a crowd dessert that feels homemade, even if made ahead.
Key Ingredients & Best Apples for Baking
The Essential Ingredients
- 2 ½ cups plain flour
- 1 teaspoon salt
- 1 tablespoon granulated sugar
- 1 cup unsalted butter (cold, cut into cubes)
- 6–7 tablespoons ice water
- 6 cups thinly sliced apples (Granny Smith, Honeycrisp, or Braeburn)
- ¾ cup brown sugar
- ¼ cup granulated sugar
- 1 teaspoon ground cinnamon
- ¼ teaspoon nutmeg
- 1 tablespoon lemon juice
- 1 tablespoon cornstarch (for thickening)
- 1 egg (for egg wash)
- Optional: coarse sugar for sprinkling
Choosing the Right Apples
Use apples that hold their shape and have balanced flavor. Granny Smith offers tangy notes; Honeycrisp or Braeburn adds juicy, floral flavors. Combining varieties creates a deeper flavor, pairing well with the crust.
Step-by-Step Preparation & Baking Process
Preparing the Crust
Mix flour, salt, and sugar in a large bowl. Cut in butter until coarse. Add ice water until the dough holds. Divide in half, shape into discs, and chill for at least 30 minutes to keep the crust flaky.
Making the Apple Filling
While the dough chills, toss apples with sugars, spices, lemon juice, and cornstarch until glossy. Lemon juice keeps apples bright; cornstarch thickens juices as they bake.
Assembling the Pie
Preheat oven to 400°F. Roll out one dough disc to fit a 10×15-inch pan. Press into corners, allowing excess overhang. Spread apple filling, cover with the second dough, trim, crimp, and cut vents. Brush with egg wash and sprinkle coarse sugar for shine.
Baking
Bake 35–40 minutes until the crust becomes golden and the filling bubbles. Cool on a rack for an hour before slicing to set the filling for easy serving.
Serve warm with vanilla ice cream and a maple glaze. It looks impressive, but it is easy to make.
Serving, Storage & Leftovers
When cool, slice your apple slab pie into neat squares. It’s ideal for parties, bake sales, or potlucks. Serve warm with whipped cream or ice cream.
Store leftovers covered at room temperature for two days or refrigerate for up to five. For a crisp crust, reheat in a 350°F oven for 10 minutes. You can freeze the baked pie tightly wrapped for three months. Thaw and briefly warm before serving.
You can also freeze the assembled pie before baking. Cover well, freeze, and when ready, bake straight from frozen, adding 10 minutes to the bake time.
Apple slab pie is timeless—unpretentious yet impressive, sentimental yet practical. Bake it for Thanksgiving, a picnic, or brunch to bring a fragrance of fall and comfort. One bite shows why this classic sheet-pan pie endures.
FAQ
What size pan should I use for an apple slab pie?
Use a 10×15-inch jelly roll or sheet pan for the right crust-to-filling ratio and even baking. Cutting bar-style slices is easy with this size.
What apples work best for an apple slab pie?
Pick baking apples that hold shape—like Granny Smith and Honeycrisp or Braeburn—for flavor depth and a filling that won’t turn mushy.
Can I make apple slab pie ahead or freeze it?
You can assemble the pie ahead and refrigerate it overnight or freeze it unbaked for three months. After baking, cool completely, wrap, and freeze slices or the whole sheet for convenience.
How should I store leftover slab pie and reheat it?
Once cool, store slab pie covered at room temperature for two days or refrigerated for four. For a crisp crust, reheat slices in a 325°F oven for 10–15 minutes.
