Ingredients for apple cranberry slab pie
Rustic crust, tart-sweet filling, and golden streusel—this pie needs just 14 ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 cups | Sifted for flaky crust |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crust |
| Granulated Sugar 🍚 | ¼ cup | For crust sweetness |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Ice Water 💧 | ½ cup | Chilled for dough |
| Firm Apples 🍎 | 4 medium | Honeycrisp or Granny Smith |
| Cranberries 🍇 | 1 cup | Fresh or frozen, chopped |
| Granulated Sugar (filling) 🍚 | ¾ cup | Adjust for tartness |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Old-Fashioned Oats 🌾 | 1 cup | Quick or rolled |
| Brown Sugar 🍚 | ½ cup | Packed for streusel |
| Unsalted Butter (streusel) 🧈 | ½ cup | Cold, cubed |

The apples are non-negotiable—Honeycrisp or Granny Smith hold their shape best. Trader Joe's usually has Honeycrisp in season, but any firm, crisp variety works. For cranberries, frozen is fine, just don't thaw them first. The butter matters too—cold cubes create flaky layers. I always buy European-style butter from Whole Foods for this recipe. If you're in a rush, pre-shredded cheese-style Parmesan won't work here—grate your own from a wedge.
No Granny Smith apples? Fuji or Pink Lady are close seconds. Short on cranberries? Substitute dried cherries at half the amount. The oats can be quick or rolled—Trader Joe's has a great bulk bin option. For the streusel, walnuts or pecans add crunch if you want texture. The cinnamon is key—Mexican cinnamon has deeper flavor, but regular works too. Fresh lemon juice brightens the filling, but bottled works in a pinch. If your filling tastes too tart, add a pinch more sugar—taste as you go!
This pie tastes even better the next day—reheat at 350°F for 10 minutes to warm through. Store wrapped at room temp for 2 days, or freeze the whole slab for 3 months. I always slice it right on the counter—no plate needed. The streusel stays crisp for hours, but the crust softens slightly. Serve with vanilla ice cream or whipped cream for maximum coziness. Leftovers? Package in single slices for easy grab-and-go dessert.

Step-by-step instructions for rustic apple cranberry slab pie
Here's how to create a showstopping slab pie with a flaky crust and perfect tart-sweet filling.
Prepare the Perfect Crust
In a large bowl, combine the 3 cups all-purpose flour with the 0.25 cup granulated sugar and 0.5 teaspoon salt. Cut in the 1 cup cold cubed unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This texture is crucial for flaky layers.
Gradually add the 0.5 cup ice water, 1 tablespoon at a time, mixing gently just until the dough comes together. The dough should hold when pressed but not be sticky. Divide the dough into two equal portions and flatten each into a disk. Wrap tightly in plastic wrap and refrigerate for at least 30 minutes (or up to 2 days).
Create the Tart-Sweet Filling
Peel, core, and slice the 4 medium firm apples into ¼-inch thick slices. Toss them with the 1 cup cranberries, 0.75 cup granulated sugar, 2 teaspoons ground cinnamon, and 1 tablespoon lemon juice in a large bowl. Let the mixture sit for 10 minutes while you prepare the streusel topping.
This resting period allows the juices to begin releasing, which helps prevent a soggy pie crust. The lemon juice brightens the flavors while the cinnamon enhances the warm spice notes that pair perfectly with cranberry tartness.
Make the Irresistible Streusel Topping
In a medium bowl, combine the 1 cup old-fashioned oats, 0.5 cup packed brown sugar, 0.5 cup cold cubed unsalted butter, and 1 teaspoon ground cinnamon. Use your fingers or a fork to work the butter into the oat mixture until it resembles coarse crumbs with some larger butter pieces remaining. This texture creates pockets of buttery flavor throughout the topping.
Spread half of the streusel mixture evenly over the bottom crust in your pie dish, creating a thin layer. This base layer ensures every bite has that perfect crunchy texture while keeping the filling moist.
Assemble and Bake the Slab Pie
Roll out one dough disk on a lightly floured surface to fit your pie dish (about 12x17 inches). Gently transfer it to the prepared dish, pressing lightly to create a smooth bottom crust. Arrange the apple-cranberry mixture evenly over the streusel base, mounding slightly in the center.
Roll out the second dough disk and place it on top of the filling. Press the edges gently to seal, then use a sharp knife to cut decorative slits in the top crust for steam to escape. Brush the top crust with a bit of milk or water for a golden finish. Bake at 375°F for 50-60 minutes until the crust is deep golden brown and the filling is bubbling through the slits.
Cool and Serve with Confidence
Remove the pie from the oven and let it cool on a wire rack for at least 2 hours before slicing. This cooling period allows the filling to set properly and prevents a runny pie. The contrast between the flaky crust, tart-sweet filling, and crunchy streusel topping makes each bite unforgettable.
Serve warm with vanilla ice cream or whipped cream for the ultimate dessert experience. The rustic slab shape makes it perfect for family gatherings or special occasions where you want to impress with a homemade pie that looks as good as it tastes.
Pro Tips For Making Apple Cranberry Slab Pie
- Chill the Butter First: Take your unsalted butter straight from the fridge and cut it into ½-inch cubes before mixing with flour—this prevents melting into a greasy mess. I learned this the hard way after trying to mix cold butter with warm hands and ending up with a soupy dough that refused to hold shape.
- Pre-Cook the Cranberries: Simmer the cranberries with sugar and a splash of water for 5 minutes before pouring into the pie—this softens them and intensifies their flavor. Skipping this step means you’ll end up with tart, undercooked cranberries that don’t blend into the apples properly.
- Use a Pie Weight or Beans: If you don’t have a pie weight, fill the empty crust with dried beans or pie weights before baking—this prevents a soggy bottom. I used to skip this and always ended up with a gummy crust, no matter how much I pre-baked it.
- Toss Apples in Lemon Juice: Toss your sliced apples with 1 tablespoon of lemon juice right after cutting—this keeps them bright and prevents browning while you prep the rest. I was skeptical until I tried it, and now I never bake apple pie without it.
Pro cooking tips for this dish
Crust Perfection
Chill your dough disks for at least 30 minutes—this prevents shrinking during baking. I use a 12x17-inch baking sheet for the slab shape, but any sturdy pan works. For extra flakiness, freeze the dough for 20 minutes before rolling. The key is cold butter—if it melts, your crust will turn tough. 🧈
Filling Balance
Taste your filling before baking—it should taste too tart when raw. The sugar will caramelize during baking, balancing the flavors. I like to add ½ tsp vanilla extract to the filling for depth. For extra texture, toss in ¼ cup chopped pecans with the cranberries. 🍎
Streusel Secrets
Use cold butter cubes in your streusel—this creates those magical buttery pockets. Don't overmix! Just combine until you see pea-sized butter pieces remaining. For a nutty twist, add ¼ cup chopped walnuts to the streusel. Spread the second half of the streusel on top after adding the filling for maximum crunch. 🌾
Baking Mastery
Bake at 375°F for 50-60 minutes—the filling should be bubbling and the crust golden. If the edges brown too fast, tent with foil. For a perfect golden top, brush with milk or egg wash before baking. Let it cool 2 hours before slicing—this prevents a runny filling. ⏰
Make-Ahead Magic
Assemble the pie (unbaked) and refrigerate for up to 24 hours—this enhances flavors. For freezing, bake the pie, cool completely, wrap tightly in plastic, and freeze for up to 3 months. Thaw overnight in the fridge before serving. The streusel stays crisp even after freezing! ❄️
Serving Brilliance
Serve warm with vanilla ice cream or whipped cream for contrast. For a fancy touch, dust with powdered sugar or garnish with fresh mint. The rustic slab shape makes it perfect for family-style serving—just slice right on the counter! 🍦

Frequently asked questions
Can I use store-bought pie crust instead of homemade?
For convenience, use two 9-inch refrigerated pie crusts (like Pillsbury). Press one into your baking dish, add the filling, then top with the second crust. Brush with milk or egg wash before baking. The texture will be slightly different but still delicious.
How do I adjust the sugar for tart cranberries?
Taste your filling before baking—it should taste too tart when raw. For very tart cranberries, add 1-2 extra tablespoons of sugar to the filling. If using dried cranberries, reduce sugar by ¼ cup since they're less tart. The baking process will balance the flavors perfectly.
Why does my streusel turn into a paste?
Overmixing the streusel causes butter to melt completely, creating a paste. Use cold butter cubes and mix just until crumbly with pea-sized butter pieces remaining. Work quickly and avoid warm hands. For extra crunch, chill the streusel for 15 minutes before adding to the pie.
Can I make this pie in a traditional pie dish?
Yes! Use a 9-inch pie dish and reduce the crust to 2 cups flour and ½ cup butter. The baking time will be 40-45 minutes at 375°F. For a deep-dish version, press the bottom crust up the sides slightly. The proportions work perfectly—just adjust the oven rack to the middle position.
How do I fix a soggy bottom crust?
Prevent sogginess by spreading half the streusel on the bottom crust first. For a baked pie, chill the assembled pie for 30 minutes before baking. If already baked, slice off the soggy bottom layer. For future pies, blind-bake the bottom crust for 10 minutes before adding filling.
