Blueberry Slab Pie

Welcome back my friends, I hope you haven’t all melted into puddles on the floor in this heat, I know I was certainly close. Leaving the house when it’s 100 degrees outside can be daunting, but if I was going to do it for anything, it would be for margarita ingredients you know? Yes, I realize that this recipe is about blueberry pie, but this is crucial. Last week, I somehow managed to injure my hand while juicing limes, which seems like an achievement even for me, so guess whose electric citrus juicer arrived on Saturday?? Naturally I had to test it out, and used this recipe, which is quite possibly the easiest and most foolproof of margarita recipes. It’s worth noting that my mom thinks this is a little too strong so we add some simple syrup to sweeten hers up, but I’ll leave that decision up to you.

But anyway, let’s talk about slab pies. For those who have no clue what that is, a slab pie is a pie baked in a large sheet pan (with raised sides, of course), resulting in a giant rectangular pie with all the buttery crust and jammy filling of a regular pie, but with THREE TIMES THE SERVINGS. If a regular 9″ pie can serve 8 people on average, a slab pie can serve up to 24 people depending on how big you slice it. If that isn’t your dream come true, then I don’t know what is! And, while we’re on the subject, this would be the perfect dessert for a July 4th BBQ- cut it into large squares, break out the vanilla ice cream, and  BOOM, you’re the star of the party.

This recipe uses my favorite pie crust recipe from Queen Ina Garten, and is filled with a blueberry filling so summery and perfect that it will bring tears to your eyes. While I am awaiting an August trip to Maine for my favorite blueberries, the ones at home worked out just splendidly. One word of caution that I have is in the transfer of pie crust from your rolling mat to your sheet pan. You’re maneuvering a large piece of dough, so I found it helpful to make sure it’s properly floured and folded in half twice to transfer, eliminating the risk of ripping the dough in too many places. Remember to breathe, stay calm, and know that rips, tears, and imperfections are ALSO beautiful! Let’s get baking!!

Serves: 16-24 people
Prep Time: 45 minutes
Bake Time: 1 hour
Total Time: ~2 hours

Pie Crust Ingredients (1 full recipe for top crust, 1 full recipe for bottom crust)
adapted from Ina Garten’s Perfect Pie Crust 

12 tablespoons cold unsalted butter, diced into cubes
3 cups all purpose flour
1 tsp kosher salt
1 tbs white sugar
1/3 cup cold shortening
½ cup ice water

Pie Crust Steps

1. In the bowl of a food processor, add the flour, salt, and sugar, then pulse 3-4 times to mix. Add in the cubed butter and shortening and pulse an additional 10 times or so, or until the butter is the size of peas and is evenly incorporated.

2. With the food processor on low, slowly add  in the ½ cup ice water and process until the dough comes together in a ball. Turn out onto a sheet of plastic wrap, and flatten into a disk. Wrap tightly and chill in the fridge for at least 1 hour. Repeat for the top crust.

 

Blueberry Filling Ingredients

5 pints blueberries
1¼ cups white sugar
½ cup flour
Kosher salt
Zest of one lemon
1 tsp vanilla extract
1 tsp cinnamon


Blueberry Filling Steps

1. Easy-peasy, toss all the above ingredients together in a large bowl, set aside while you roll out the pie crusts.

 

Slab Pie Assembly Extra Ingredients

1 egg
1 tbs water
Demerara Sugar


Slab Pie Assembly Steps

1. Preheat your oven to 400ºF. On a large silpat mat or floured surface, roll out your first batch of pie crust into a large rectangle- make sure you have an extra inch on all sides compared to the size of your sheet pan, so that it can cover the sides. For reference, mine was roughly 10″ by 16″.

2. To transfer the bottom crust to the baking sheet, carefully fold the crust in half vertically, then again horizontally, and place in one corner of the tray. Unfold veeeeeeery carefully, and gently pull into place as needed so that the bottom and sides are covered. Pour in the filling.

3. Repeat the rolling and folding process for the top crust and place into position. Fold the bottom crust over the top crust and crimp all the edges using a fork or your hands. Cut several slits in the top of the pie to release the steam, and brush the entire top with egg wash (1 egg + 1 tbs water). Sprinkle generously with demerara sugar.

4. Bake at 400ºF for the first 20 minutes, then turn the oven down to 350ºF and bake for an additional 40 minutes, checking every 15-20 minutes or so to make sure the edges aren’t browning too much. If you find that the crust is getting too dark for comfort, cover the dark areas with tinfoil to prevent burning.

5. Cool completely to allow the filling to set, but it can be warmed again for serving! Serve with a scoop of ice cream and enjoy!
