8x8 Slab Pie Recipe: Easy, Delicious Homemade Treat

The 8×8 slab pie is a straightforward, crowd-pleasing dessert that fits perfectly in a standard square baking pan. It’s an excellent way to enjoy the classic flavors of pie without the fuss of shaping a traditional crust or making individual servings. This recipe balances a flaky, buttery crust with a luscious fruit filling, making it ideal for casual get-togethers or a simple family dessert.

Ingredients

1 1/4 cups (155g) all-purpose flour
1/2 teaspoon salt
1/2 cup (115g) unsalted butter, cold and cubed
3 to 4 tablespoons ice water
3 cups fresh or frozen fruit (e.g., apples, berries, peaches), peeled and sliced if needed
2/3 cup (130g) granulated sugar
2 tablespoons cornstarch
1/2 teaspoon ground cinnamon (optional, depending on fruit)
1 tablespoon lemon juice
1 teaspoon vanilla extract (optional)
1 egg, beaten (for egg wash)
1 tablespoon coarse sugar (optional, for topping)

Instructions

Prepare the crust: In a large bowl, whisk together the flour and salt. Add the cold, cubed butter. Using a pastry cutter or your fingertips, quickly cut the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces remaining.

Add ice water: Sprinkle 3 tablespoons of ice water over the mixture. Gently mix with a fork until the dough begins to hold together. If needed, add the remaining tablespoon of ice water, but avoid overworking the dough.
Form and chill the dough: Turn the dough onto a lightly floured surface and gently press it into a 5-inch disk. Wrap in plastic wrap and refrigerate for at least 30 minutes to firm up.
Preheat oven and prepare pan: Preheat your oven to 375°F (190°C). Lightly grease an 8×8-inch square baking pan or line it with parchment paper, leaving an overhang for easy removal.

Roll out the dough: On a floured surface, roll the chilled dough into a 9×9-inch square to allow for some crust folding. Carefully transfer the dough to the baking pan, pressing it gently into the corners and up the sides about 1 inch.
Make the filling: In a medium bowl, combine the fruit, sugar, cornstarch, cinnamon (if using), lemon juice, and vanilla extract. Toss gently until the fruit is evenly coated.
Assemble the pie: Pour the filling evenly into the prepared crust. Fold the edges of the dough over the filling to create a rustic border, leaving the center exposed.

Apply egg wash: Brush the exposed crust edges with the beaten egg. Sprinkle coarse sugar on top if desired for extra crunch and sweetness.
Bake: Bake in the preheated oven for 40 to 45 minutes, or until the crust is golden brown and the filling is bubbling. If the crust edges brown too quickly, loosely cover them with foil halfway through baking.
Cool and serve: Remove from oven and let the slab pie cool on a wire rack for at least 30 minutes before slicing. This helps the filling set and makes cutting easier.

Tips

Substitutions: You can swap out the butter for cold coconut oil for a dairy-free crust, but the texture will be slightly different—still delicious but less flaky.
Fruit options: Use any seasonal fruit or a combination. For very juicy fruits like berries, increase cornstarch to 3 tablespoons to prevent a runny filling.
Storage: Store leftover slab pie covered tightly at room temperature for up to 2 days or refrigerated for up to 4 days.

Common mistakes: Avoid overworking the dough to keep it tender. Also, ensure fruit pieces are uniform in size for even cooking.

Serving Suggestions

This 8×8 slab pie is wonderful served warm or at room temperature. Pair it with a scoop of vanilla ice cream or a dollop of whipped cream for a classic dessert experience. For a cozy twist, drizzle with caramel sauce or a sprinkle of toasted nuts. It also makes a lovely breakfast treat when paired with a cup of coffee or tea.

Variations

To customize your slab pie, try these variations:

Peach and Blueberry: Combine sliced peaches and fresh blueberries with a pinch of nutmeg for a summery flavor.

Apple Cinnamon: Use tart apples with extra cinnamon and a splash of maple syrup in the filling.
Mixed Berry: Blend strawberries, raspberries, and blackberries for a vibrant, colorful pie.
Savory version: Substitute fruit with caramelized onions, goat cheese, and herbs for a savory slab pie perfect for brunch.

Storage and Reheating

Store the slab pie in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 4 days. To freeze, wrap tightly in plastic wrap and aluminum foil; it will keep well for up to 2 months. When ready to eat, thaw overnight in the refrigerator, then reheat slices in a 350°F (175°C) oven for 10–15 minutes until warm. Avoid microwaving if possible, as it can make the crust soggy.

Frequently Asked Questions

Can I make the dough ahead of time?
Yes, the pie dough can be made up to 2 days in advance. Keep it wrapped tightly in plastic wrap and refrigerated. Bring it to a slightly chilled but pliable state before rolling out.

What if I don’t have cornstarch for the filling?
You can substitute with tapioca starch or arrowroot powder in equal amounts. These thickeners help absorb excess fruit juice and keep the filling from becoming watery.

Why is my crust tough instead of flaky?
Overworking the dough or adding too much water can develop gluten, resulting in a tough crust. Use cold butter and minimal water, mix just until combined, and chill the dough well before baking.

Can I use frozen fruit in this recipe?
Yes, frozen fruit works well but should be thawed and drained of excess liquid before mixing with sugar and thickener. This prevents a soggy crust and watery filling.

How do I prevent the edges of the crust from burning?
If you notice crust edges browning too quickly during baking, cover them loosely with aluminum foil halfway through the baking time. This shields the crust while allowing the filling to cook fully.

Is the 8×8 slab pie suitable for portion control?
Absolutely. The slab pie can be sliced into small squares, making it easy to serve controlled portions. It’s ideal for gatherings where you want a simple, shareable dessert.
