Techniques Required for Making Strawberry Blackberry Slab Pie

How to make the pie crust: The pie crust is made by mixing the flour, salt, and sugar together, then cutting in the butter until pea-sized crumbles form. Cold water is then added gradually until the dough comes together. The dough is divided, shaped into discs, and chilled before rolling out.

How to make the filling: The filling is made by gently mixing together the fresh strawberries, fresh blackberries, granulated sugar, cornstarch, lemon juice, vanilla extract, and a pinch of salt in a large bowl.

How to assemble the slab pie: The pie dough is rolled out into a rectangle or oval shape and placed onto a large rimmed baking sheet. The filling is spooned evenly on top of the crust, leaving a bare 1-inch border around the edges. The second pie dough disc is rolled out, draped over the filling, and sealed together with the bottom crust. The edges are fluted or crimped, and the top crust is brushed with egg wash and sprinkled with coarse sugar before baking.

How to bake the slab pie: The assembled slab pie is baked at 375 degrees F for about 45 to 55 minutes until the crust is golden brown and the filling is bubbling. After baking, the pie is allowed to cool before serving.

  • ¾cupice cold water
  • 1large egg,(lightly beaten with 1 tbsp milk)

  • 4cupsfresh blackberries,halved
  • ½cupgranulated sugar
  • ¼cupcornstarch
  • 1tbsplemon juice
  • 1tsppure vanilla extract
  • pinchsalt



  1. Mix the flour, salt, and sugar together in a large bowl. Add the butter. Using a pastry cutter, a food processor, or two forks, cut the butter into the mixture until there are pea-sized crumbles with a few larger crumbs of fat.

  2. Drizzle the cold water in, 1 tablespoon at a time, and stir after every tablespoon added. Stop adding water when the dough begins to form large clumps.

  3. Transfer the pie dough to a floured work surface. Using floured hands, fold the dough into itself until the flour is fully incorporated into the butter pieces. The dough should come together easily and should not feel overly sticky.

  4. Form dough into a ball. Divide dough in half. Flatten each half into 1-inch thick discs. Wrap each tightly in plastic wrap.

  5. Refrigerate for at least 2 hours (and up to 5 days) or freeze for up to 3 months. Thaw overnight in the fridge before using.


  1.  Gently mix all of the filling ingredients together in a large bowl. Set aside.

  2. Preheat oven to 375 degrees F.

  3. Remove 1 disc of pie dough from the refrigerator. Keep the other in the refrigerator. Roll the dough out into a rectangle or oval shape.

  4. Dough should be about ⅛-inch thick. Make sure to turn the dough about a quarter turn after every few rolls. Carefully place the dough (with parchment/silicone baking mat) onto a large rimmed baking sheet.

  5. Spoon filling evenly on top of crust, leaving any excess liquid in the bowl. Leave a bare 1-inch border around the edges.

  6. Roll out the 2nd pie dough disc in the same-ish shape as the 1st. Drape over filling, then seal the top and bottom crusts together around the edges.

  7. Flute the edges or crimp with a fork. Cut slits into the top of the crust, then brush with a thin coating of egg wash. Sprinkle with coarse sugar, if desired.

  8. Bake the slab pie for about 45 to 55 minutes until the crust is golden brown and the filling is bubbling. Remove from the oven and, if serving as hand-held bars, allow to cool completely in the pan set on a wire rack.

  9. If serving on plates, allow to cool for at least 45 minutes in the pan set on a wire rack.

  10. Cover leftovers tightly and store in the refrigerator for up to 3-4 days.

Crucial Technique Tip for a Perfect Slab Pie

When making the pie crust, it's important to keep all the ingredients as cold as possible. This includes the butter and water. The reason for this is that the cold fat will create pockets of air as it melts in the oven, resulting in a flaky and tender crust. If the fat is too warm, it will be absorbed by the flour and result in a tough crust. To achieve this, you can cut the butter into small pieces and freeze them for about 15 minutes before using. Also, use ice water instead of room temperature water.

Time-Saving Tips for Making a Slab Pie

Prepare the crust: Use a food processor to quickly cut the butter into the flour mixture until it resembles coarse crumbs. This will save time and effort compared to using a pastry cutter or forks.

Chill the dough: Divide the dough into discs before chilling. This will help it chill faster and more evenly, saving you time when you're ready to roll it out.

Use pre-made crust: If you're short on time, consider using store-bought pie crust to streamline the process without sacrificing flavor.

Prep the filling in advance: Prepare the fruit filling ahead of time and store it in the refrigerator. This will save time on the day you plan to bake the pie.

Bake in advance: If possible, bake the slab pie a day ahead to allow it to cool and set properly, saving time on the day of serving.

Invest in a good quality pie dish: A high-quality pie dish can help the crust bake more evenly and prevent burning, saving time and ensuring a perfect result.

Substitute Ingredients For Strawberry Blackberry Slab Pie Recipe

  • all-purpose flour - Substitute with whole wheat flour: Whole wheat flour can add a nutty flavor and a denser texture to the crust, which can complement the sweetness of the berries.
  • unsalted butter - Substitute with coconut oil: Coconut oil can provide a subtle tropical flavor to the crust and works well as a dairy-free alternative.
  • granulated sugar - Substitute with honey: Honey can add a natural sweetness and a hint of floral flavor to the crust, enhancing the overall taste of the pie.
  • strawberries - Substitute with raspberries: Raspberries can offer a similar tartness and vibrant color to the filling, creating a visually appealing and delicious alternative.
  • blackberries - Substitute with blueberries: Blueberries can provide a slightly sweeter flavor and a beautiful purple hue to the filling, adding a delightful twist to the pie.
  • cornstarch - Substitute with arrowroot powder: Arrowroot powder can act as a thickening agent for the filling, creating a glossy texture and a neutral taste.

Presenting Your Strawberry Blackberry Slab Pie

  1. Elevate the crust: Create a decorative lattice or intricate design on the crust to showcase your attention to detail and precision in pastry work.

  2. Garnish with fresh berries: Arrange a selection of fresh strawberries and blackberries on top of the pie to add a pop of color and freshness to the presentation.

  3. Dust with powdered sugar: Lightly dust the slab pie with powdered sugar just before serving to add a touch of elegance and a hint of sweetness to the dessert.

  4. Accompany with vanilla bean whipped cream: Serve a dollop of vanilla bean whipped cream on the side to complement the flavors of the pie and add a luxurious touch to the overall presentation.

  5. Incorporate edible flowers: Integrate delicate and colorful edible flowers, such as violets or pansies, to bring a sophisticated and visually stunning element to the dessert.

  6. Present on individual dessert plates: Serve each portion of the slab pie on individual, carefully selected dessert plates to create a sense of individuality and refinement for each guest.

  7. Add a drizzle of berry coulis: Drizzle a vibrant berry coulis on the plate in an artistic manner to enhance the visual appeal and provide a complementary burst of fruity flavor.

  8. Use gold leaf accents: For an opulent touch, consider adding delicate, edible gold leaf accents to the presentation, elevating the dessert to a luxurious and extravagant level.

Essential Tools for Making a Slab Pie

  • Pastry cutter: A handheld tool with curved blades used to cut fat into flour when making pastry dough.
  • Food processor: A kitchen appliance used to mix, puree, or chop ingredients quickly and efficiently.
  • Rolling pin: A cylindrical tool used to flatten and shape dough for pie crusts and other baked goods.
  • Baking sheet: A flat, metal pan used for baking cookies, pastries, and other baked goods in the oven.
  • Parchment paper: A non-stick paper used to line baking sheets or pans to prevent sticking and make cleanup easier.
  • Silicone baking mat: A reusable non-stick baking surface that can be placed on baking sheets for easy release of baked goods.
  • Wire rack: A metal rack used for cooling baked goods and allowing air to circulate around the food.

Storing and Freezing Your Strawberry Blackberry Slab Pie

  • Cover leftovers tightly with plastic wrap or aluminum foil and store in the refrigerator for up to 3-4 days. The pie will taste best within the first 24-48 hours.
  • To freeze, let the slab pie cool completely. Once cooled, wrap the pie tightly with plastic wrap or aluminum foil, then place in a freezer-safe container or freezer bag. Label with the date and freeze for up to 3 months.
  • When ready to eat, thaw the pie overnight in the refrigerator. Once thawed, you can reheat individual slices in the microwave for 30-45 seconds or until warmed through. Alternatively, you can reheat the entire pie in a preheated 350°F (175°C) oven for 15-20 minutes or until warmed through.
  • If you prefer a crispier crust after freezing and thawing, you can place the slab pie under the broiler for a few minutes, watching carefully to prevent burning.
  • For best results, freeze the pie as soon as possible after baking and cooling to maintain its freshness and texture. Avoid freezing the pie multiple times, as this can affect the quality of the crust and filling.

How To Reheat Leftover Slab Pie

  • The best way to reheat leftover strawberry blackberry slab pie is in the oven. Preheat your oven to 350°F (175°C) and place the pie on a baking sheet lined with parchment paper or aluminum foil.
  • If the crust seems too brown, cover the edges with foil to prevent further browning. Bake for 15-20 minutes, or until the filling is heated through and the crust is crisp.
  • For a quicker option, you can reheat individual slices in the microwave. Place a slice on a microwave-safe plate and heat for 30-45 seconds, or until warmed to your liking. Be aware that the crust may soften slightly in the microwave.
  • If you prefer a crispy crust, you can also reheat individual slices in a toaster oven. Preheat the toaster oven to 350°F (175°C) and place the slice on a small baking sheet or directly on the rack. Heat for 5-7 minutes, or until the filling is warm and the crust is crisp.
  • For a tasty twist, try serving your reheated slab pie with a scoop of vanilla ice cream or a dollop of freshly whipped cream. The contrast of warm pie and cool, creamy toppings is sure to delight your taste buds.
  • If you find that your leftover pie filling has thickened too much upon refrigeration, you can stir in a tablespoon or two of water or lemon juice to help loosen it up before reheating. This will help ensure a smooth, luscious filling texture.

Is This Slab Pie Healthy or Unhealthy?

  • Experiment with reducing the butter in the crust by 25% and replacing it with Greek yogurt or coconut oil
  • Serve smaller portions and pair with a dollop of Greek yogurt for added protein and a lighter alternative to whipped cream
  • Incorporate additional fresh fruits, such as sliced peaches or raspberries, to increase the nutritional value and fiber content of the filling
