Best 12 Blueberry Rhubarb Slab Pie Recipes

AMAZING BLUEBERRY RHUBARB PIE

Steps:

• Preheat oven to 400 degrees F (200 degrees C).
• Stir white sugar, brown sugar, tapioca, and salt together in a large bowl. Add rhubarb and blueberries; toss to coat.
• Divide the pie dough in half and roll each half out into a 9-inch round. Place 1 round of dough in the bottom of a pie plate. Pile rhubarb-blueberry mixture on top of the dough and top with the remaining dough round. Trim excess dough from the top crust to leave a 1/2-inch border below the top rim of the pie plate. Tuck the top edges of the crust under the bottom crust and crimp border together. Place pie plate on a rimmed baking sheet.
• Bake in the preheated oven for 20 minutes. Reduce oven temperature to 350 degrees F (175 degrees C) and continue baking until the crust is golden brown and the filling is bubbling, 25 to 30 minutes more. Cool for 2 hours.

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 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 PIE

Steps:

• Heat oven to 425 degrees. Roll out both crusts. Line a deep 9-inch pie pan with the bottom crust and return both crusts to the refrigerator.
• In a medium bowl, combine rhubarb, berries, sugar, flour, tapioca, salt, nutmeg and lemon juice. Toss to coat and combine, then scoop into waiting bottom crust. The fruit should come up to within 1/2-inch of the rim of the pan; do not overfill. If necessary, add more or subtract some of the fruit. Break the butter into pieces and dot over the fruit.
• Lay top crust over filling. Trim excess dough from the edges and crimp, then cut 6 or 7 vents on top. Brush a light coating of egg wash over the crust, including the edges.
• Bake for 20 minutes. Reduce heat to 375 degrees. Bake another 25 minutes, then open the oven and quickly sprinkle the crust with a thin coating of granulated sugar. Bake another 10 to 15 minutes, or until you see steady bubbling in the filling coming through the vents.
• Remove pie from oven and listen to it: if the crust is sizzling, and the filling is audibly bubbling against the top crust, it is done. Let cool completely before serving.

BLUEBERRY RHUBARB PIE

Steps:

• Preheat oven to 400°.
• Combine sugars, salt and tapioca in a large bowl and mix well. Add fruit and toss until well coated.
• Mound fruit mixture in 9-inch pie pan lined with pastry dough. Top with second crust, trimming so that top crust hangs 1/2 inch beyond rim. Tuck edge of top crust under bottom crust and crimp.
• Bake 20 minutes. Reduce temperature to 350° and bake an additional 25-30 minutes, until pie is golden and the juices are bubbling. Let cool 2 hours and then serve.

PEACH-BERRY RHUBARB SLAB PIE

Steps:

• Prepare the crust. In a medium bowl, stir together flour and salt until well combined. Add 1/3 cup butter and the shortening, then cut in with a pastry blender until flour appears crumbly and no crumbs are larger than pea size. Gradually add water, one tablespoon at a time, tossing thoroughly with fork after each addition until dough sticks together. Dough should be only slightly moist and should still retain a crumbly appearance until pressed together between fingers. Place mixture into an ungreased 9 x 13 inch glass baking dish and flatten to bottom, pressing dough halfway up the sides of the baking dish. Melt the remaining tablespoon of butter and brush over crust using a pastry brush. Immediately sprinkle with cinnamon and sugar and set aside.
• Make the filling. Peel and slice two of the peaches and place into a medium bowl. Add strawberries, blackberries, raspberries, and rhubarb. In a small bowl, combine 1 tablespoon flour and 2 tablespoons sugar, then pour over fruit and toss until fruit is evenly coated. Set aside.
• Preheat oven to 350 degrees. In a medium sauce pan, add remaining peaches (peeled and sliced), cinnamon, butter, corn syrup, honey, lemon jice, orange juice, and sugar. Begin cooking over medium heat, stirring constantly until juices form. Mix corn starch with 1 teaspoon of water and gradually pour into mixture while stirring constantly. Allow mixture to come to a boil. Continue to boil, stirring occasionally, until mixture thickens. Once thickened, stir constantly until the liquid portion of the filling sticks to the spoon when removed from the pan. It should almost have the appearance of cooled pie filling. Remove from heat and add remaining fruit, stirring juices into flour mixture before adding to the filling. Lightly stir to combine and set aside.
• Place empty pie crust in the oven on the middle rack and bake until the butter is melted and the cinnamon and sugar appear to have absorbed into the crust.
• In the meantime, prepare the streusel. In a medium bowl, combine all ingredients and stir together until crumbly and all dry ingredients appear a bit moist. Set aside.
• Remove crust from the oven and top evenly with pie filling. Cover with the streusel, paying special attention to the sides as the filling tends to bubble up over the topping along the edges. Bake on center rack for approximately 45 minutes, or until crust appears golden and streusel is crunchy. Remove from oven and cool, then slice into 12 pieces.

BLUEBARB PIE

Steps:

• Preheat an oven to 425 degrees F (220 degrees C). Line a baking sheet with aluminum foil and place on lower oven rack.
• Toss the rhubarb and blueberries in a bowl with the salt, nutmeg, lemon juice, 1 1/3 cup sugar, and flour until evenly mixed. Pour into the pie shell and dot with butter.
• Cover the filled crust with the top crust and flute the edges. Cut a few decorative steam vents in the top crust. Sprinkle the crust with 1 tablespoon of sugar; cover the fluted edges with aluminum foil to prevent excessive browning.
• Bake in the preheated oven on the baking sheet for 15 minutes; reduce the heat to 350 degrees F (175 degrees C) and bake 35 minutes longer. Remove the foil and continue baking until the crust is golden and juice is bubbling through the slits, about 15 minutes more. Cool completely before serving.

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.

STRAWBERRY-RHUBARB SLAB PIE

Steps:

• Make crust: In a food processor, pulse flour, granulated sugar, and salt until combined. Add butter and 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; do not overmix. Divide dough into 2 disks, wrap each tightly in plastic, and refrigerate until firm, at least 1 hour (or up to overnight).
• Preheat oven to 400 degrees. Make filling: In a large bowl, toss together strawberries, rhubarb, granulated sugar, light-brown sugar, tapioca, and orange zest and juice.
• Lightly flour a work surface and rolling pin. Roll out 1 disk to a 12-by-16-inch rectangle. Transfer dough to a 10-by-14-inch jelly-roll pan. Press gently to fit into pan and fill with fruit mixture. Roll out remaining disk to an 11-by-15-inch rectangle. Place atop pie, pressing along edges to seal. Trim edges of dough, leaving 1 1/2-inch overhang all around. Fold overhang under, tucking it into pan. Crimp edges. Brush crust all over with egg-yolk mixture and sprinkle with sanding sugar, if desired.
• With a paring knife, cut slits on top to vent. Place pie in oven, then reduce temperature to 375 degrees. Bake until crust is deep golden brown and juices are bubbling in center, 55 to 65 minutes. Let cool on a wire rack, 1 hour. Serve warm or at room temperature.
