Best Blueberry Slab Pie Recipes

BLUEBERRY CRUMBLE SLAB PIE

Steps:

• Heat oven to 400° F. Place both pie crusts in half-sheet pan, overlapping slightly. Fit into pan, pressing into corners. Trim edges to about 1/2 inch overhanging sides of pan, then fold over and tuck into pan.
• In large bowl, toss Filling ingredients. Dump into crust.
• In small bowl, mix Topping ingredients with fork. Use fingers to form olive-sized chunks of topping. Scatter over top of filling.
• Bake 40 to 45 minutes or until topping is golden and blueberry filling is bubbling. Cool slightly. If desired, serve with vanilla ice cream or whipped cream.

BLUEBERRY SLAB PIE

Steps:

• In a large, flat-bottomed bowl, combine flour, sugar, and salt. Add the butter cubes and toss to coat with the flour mixture. Use a pastry blender to cut the butter into the flour; do not smash or smear the butter. Scrape butter off the pastry blender during the mixing process and continue mixing. (If butter is softening too fast, put the bowl in the refrigerator until butter firms up, 2-5 minutes.) Continue cutting, working quickly, until butter is broken down and looks like a coarse crumble with only a few larger pieces.
• Combine vinegar with water and ice; you'll use up to 1½ cups of this liquid in the pie dough, a tablespoon at a time. Begin by sprinkling about 8 tablespoons of liquid over the flour mixture; use a bench scraper or your hands to incorporate until the mixture begins to come together. Sprinkle in 8 more tablespoons of liquid and continue the mixing process. Squeeze a fistful of dough: if it holds, like wet sand, it's ready. If it falls apart, add 1-2 more tablespoons of liquid at a time, squeezing the dough to check if it holds. Bring all the dough together, sprinkling dry bits with more small drops of liquid as necessary; dough will look shaggy. Knead in the bowl just until incorporated.
• Turn dough onto a work surface and use a bench scraper to divide dough into two equal pieces. Shape into flat disks and wrap in plastic; refrigerate for at least 30 minutes, preferably overnight. Dough can be refrigerated for up to 3 days and frozen up to 1 month, tightly wrapped.
• Generously butter a baking sheet and line with parchment paper. Dust a large work surface and tapered French rolling pin with flour. Roll out 1 disc of chilled pie dough into a rectangle by rolling it in an "X," diagonally, for even stretching. (If dough is softening too fast at any point in the rolling process, chill in the refrigerator until firm, 2-5 minutes.) Once the dough has been thinned out, switch to a straight French rolling pin and continue rolling the dough until it's a rectangle of even thickness, 3-4 inches larger than the baking sheet. Fit the dough into the baking sheet by gently folding in half, then in half again. Align the creases squarely in the middle of the pan, then unfold the dough so it's centered in the pan. There should be a 1-inch dough overhang on all sides. (If necessary, it's okay to stretch the dough gently.) Repeat the rolling and shaping process with top crust dough to a 17" x 13" rectangle. Invert a rimmed baking sheet and spread the dough on top. Refrigerate both sheets while assembling the filling, 20 minutes.
• Filling: Taste your blueberries first. They can vary from really sweet to really tart which will affect how much sugar is added; add or take out up to ¼ cup sugar to adjust sweetness. In a small bowl, mix shredded apple with lemon juice. In a large bowl, combine both sugars, Angostura bitters, allspice, cloves, cinnamon, cardamom, salt, and ground arrowroot. Add the blueberries, crushing about half of them with your hands; mix well to combine, making sure no spices remain at the bottom of the bowl.
• Preheat oven to 425 F. Remove the chilled dough sheets; set the top dough aside. Transfer the filling into the dough-lined baking sheet, patting it down to make sure there are no gaps. Use the round pastry cutter to punch random holes into the top dough, 2-3 inches apart, to create a polka dot effect; don't get too close to the edges. (Save the pastry circles to make crust cookies!) Place the top dough sheet squarely over the filling, then seal the top and bottom crusts by tucking and pinching excess dough under the bottom crust. Seal again by pressing circumference of crust with your thumbs.
• Brush egg wash evenly over the top crust, and sprinkle with raw sugar. Pie will bake for a total of 1 hour. Bake on the lowest rack of the oven until crust is set and beginning to brown, 20-25 minutes. Lower heat to 375 F, move the pie to the center oven rack, and continue to bake until crust is a deep golden brown and juices are bubbling throughout, about 30-35 minutes longer. Allow pie to cool completely on a wire rack before cutting into it, 1-2 hours. Serve slightly warm or at room temperature.

BLUEBERRY SLAB PIE

Steps:

• Make crust: In a food processor, pulse flour, salt, and sugar until combined. Add butter; pulse until mixture resembles coarse meal, with a few pea-size pieces of butter remaining. With machine running, add 1 cup ice water. Pulse until dough is crumbly but holds together when squeezed (if necessary, add up to 1/2 cup water, 1 tablespoon at a time). Do not overmix. Divide dough into 2 disks; wrap each tightly in plastic. Refrigerate until firm, at least 1 hour (or up to overnight).
• Preheat oven to 400 degrees. Make filling: In a large bowl, toss together blueberries, cornstarch, sugar, and lemon zest and juice. On a floured work surface, roll out 1 disk to a 12-by-16-inch rectangle. Place in a 10-by-14-by-1-inch rimmed jelly-roll pan. Pour in blueberry filling, then lightly brush edges of crust with water. On floured surface, roll out second disk to an 11-by-15-inch rectangle and lay over blueberry filling; press along moistened edges to seal. Fold overhang under, tucking it into pan, and crimp edges. With a paring knife, cut slits on top to vent.
• Place pie in oven, then reduce heat to 375 degrees. Bake until crust is golden and juices are bubbling, 50 minutes. Let cool on a wire rack 1 hour. Serve warm or at room temperature.

BLUEBERRY-RHUBARB SLAB PIE

Steps:

• Prepare the pastry: In the bowl of a food processor, combine the flour, sugar and salt. Add the butter and pulse until the mixture is the texture of coarse sand with some larger pieces of butter. Drizzle in 1/3 cup ice water and pulse the mixture about 5 times or until the mixture is crumbly, but evenly moistened and holds together when you squeeze a bit in your hands. Add up to 3 more tablespoons ice water, but stop before the mixture becomes too wet.
• Tip the mixture out onto a large piece of plastic wrap. Using the plastic wrap, press the crumbs together. Divide the dough into thirds; tightly wrap one portion in plastic wrap, then combine the other two portions and wrap that larger piece of dough well in plastic wrap. Use a rolling pin to press both dough portions into two flat rectangles. Chill for at least 2 hours. (You can chill dough for up to 3 days in the fridge or freeze it for up to 3 months.)
• Meanwhile, prepare the filling: In a small saucepan, combine the rhubarb, 3 cups blueberries, the maple syrup and salt. Cook the mixture over medium heat, stirring occasionally, until the rhubarb has started to break down and the blueberries have started to release some of their juices, about 10 minutes.
• Transfer a few tablespoons of the liquid from the saucepan to a small bowl. Add the cornstarch and whisk until dissolved. Return the cornstarch mixture to the pan and cook, stirring, until the blueberry mixture has thickened, 2 minutes. Remove the pan from the heat and stir in the remaining 1 1/2 cups blueberries and the ginger. Let this mixture cool completely.
• On a lightly floured piece of parchment, roll the larger portion of dough into an 11-by-13-inch rectangle. Trim the edges into straight lines. Transfer the parchment with the dough to a rimmed baking sheet. Roll the smaller portion of dough out to a 7-by-15-inch rectangle on a floured piece of parchment. Using a fluted pastry wheel or a sharp knife, cut the dough lengthwise into seven 1-inch-thick strips.
• Spread the filling over the uncut rectangle, leaving a 1-inch border on all sides. Lay the strips of pastry over the filling on the diagonal, spacing the strips about 1/2 inch apart. Trim the strips so that they are even with the edge of the rectangle. Fold the edges up and over the filling and the strips and press the corners to seal. (Press with the tines of a fork, if desired.) Wrap lightly with plastic wrap and freeze for at least 30 minutes (and up to 2 hours).
• Heat the oven to 400 degrees. Using the parchment, transfer the chilled pie to another rimmed baking sheet. (You don't want to bake it on the cold sheet.) Brush the beaten egg all over the pastry and sprinkle with sanding sugar.
• Bake until the pastry is deep golden brown and the filling is bubbling in spots, 50 to 60 minutes. Transfer pan to rack to cool for at least 1 hour before slicing.

BLUEBERRY PEACH SLAB PIE

Steps:

• In the bowl of a food processor, pulse 2 1/2 cups flour, 1 teaspoon salt, and 1 1/2 tablespoons sugar. Add half the butter and pulse until coarse, pea-sized crumbs appear. With the machine running, add 1/4 cup ice water and process until the dough just holds together. Squeeze a small amount of dough between your fingers and if it is very crumbly, add more ice water, 1 tablespoon at a time (2 tablespoons maximum). Do not over process.
• Turn dough out onto a lightly floured surface and push together into a rough ball. Knead a few times to combine. Flatten into a disc, cover with plastic wrap, and refrigerate at least 1 hour or overnight. Repeat the same procedure with remaining 2 1/2 cups flour, 1 teaspoon salt, 1 1/2 tablespoons sugar, and butter. Flatten into a second disc and refrigerate at least 1 hour or overnight.
• Preheat oven to 425°F. Position one oven rack on the bottom rung and one in the center of the oven. Completely line bottom rack with foil to catch filling drips and place one 13x18-inch rimmed baking sheet on top of foil to preheat.
• Grease another 13x18-inch rimmed baking sheet with butter. On a floured surface, roll out 1 disc of dough into a 14x19-inch rectangle, about 1/8-inch thick. Roll dough onto rolling pin and unfurl onto greased baking sheet. Press dough into baking sheet and over rimmed edge; trim dough at rimmed edge. Refrigerate 30 minutes. Roll out second disc of dough to the same size, transfer to a large cutting board or 2 pieces of parchment taped together, and refrigerate 30 minutes.
• In a small bowl, whisk together the egg and milk to create an egg wash, set aside. Bring a large pot of water to a boil and fill a large bowl with ice water. Using a paring knife, lightly score the bottom of each peach with an "x". Drop peaches into water for 1 to 2 minutes to loosen skins and transfer to the ice water bath. Once cool enough to handle, remove the skins. Slice into 1/2-inch thick wedges. Place sliced peaches in a large bowl with blueberries, remaining 1/2 teaspoon salt, 1 1/4 cups sugar, cornstarch, vanilla, and lemon. Toss well to combine. Fill the dough lined baking sheet with the fruit mixture.
• Brush the outside edge of filled dough with egg wash. Top with the second dough rectangle. Press top and bottom crusts together and trim top crust to rimmed edge of baking sheet. Tuck and fold edges into base of baking sheet and crimp or decorate as desired. Brush top crust with egg wash and sprinkle with sanding sugar. Using a paring knife, cut vents in the top crust to release steam.
• Slide the filled baking sheet into the preheated baking sheet and bake on bottom rack until the crust begins to turn golden, about 25 minutes. Rotate stacked sheets, move to center rack, and reduce oven to 350°F. Keep foil on bottom rack. Continue baking, rotating sheet again half way through, until the crust is golden brown and you can see the thickened juices bubbling, 60 to 70 minutes more. Cover crust with foil if it begins to darken too much before juices are bubbling. Cool on a rack at least 2 hours to allow juices to set before slicing.

BLUEBERRY SLAB PIE

Steps:

• Stir together the blueberries, lemon zest and lemon juice in a medium pot. Begin to heat over medium heat, stirring occasionally, until the berries begin to burst, 3 to 5 minutes. Use a potato masher to smash the berries a couple times at the beginning to help encourage the process.
• Stir together the sugar, cornstarch and salt in a small bowl. Sprinkle this mixture over the berries and stir well to combine. Continue to cook over medium-low heat, stirring constantly, until the mixture begins to thicken and bubble from the center of the pot, 2 to 3 minutes.
• Stir in the butter and vanilla until well combined. Cool the filling completely. (The filling can be made up to 2 days ahead; store in an airtight container in the refrigerator.)
• On a clean, dry work surface, gently roll out one of the sheets of puff pastry with a rolling pin to flatten it, flouring the surface only if necessary. Gently transfer the dough to a shallow 9-by-13-inch pan (such as a quarter baking sheet) pressing firmly into the base and edges and allowing the excess to hang off the sides. Pour the cooled filling into the crust and spread in an even layer. Chill while you prepare the remaining dough.
• Roll out the second sheet of puff pastry the same way. Gently transfer to the top of the pie and press the edges firmly all the way around to seal and flatten slightly. Gently fold the edges of the crust under itself all the way around. Use a fork or your fingers to crimp and seal the pie.
• Chill the pie in the refrigerator while you preheat the oven to 400 degrees F with a rack in the lower third (if you have a pizza stone, place it on the rack).
• Whisk together the egg and water in a small bowl. Brush the egg wash mixture over the crust, focusing on the center portion rather than the edges, which tend to brown enough on their own. Sprinkle turbinado sugar evenly over the pie. Cut a few vents into the center of the pie with a paring knife.
• Transfer the pie to the oven (on top of the pizza stone if using). Bake until the pie is deeply golden brown and the filling bubbles through the vents, 35 to 40 minutes. Cool at least 1 hour before slicing and serving.
