My son is a big fan of berry pie. He even requested one in lieu of a cake for his birthday one year. Each summer when delicious berries are in abundance, I make him his favorite pie which he usually likes to top with a scoop of vanilla ice cream. As usual, he scarfs it down within the minute and quickly makes his way back for seconds. I usually give in to his second helping and then cover and put the pie away so that it lasts longer than 10 minutes. I mean I did just spend hours in the kitchen making it!
Since 4th of July is right around the corner, I decided to make a slab pie which easily feeds a crowd. They’re very similar to regular pies but made in a big sheet pan and are cut into squares instead of triangular slices. This makes it much easier to serve and less messy too since the pie is shallow. Instead of a rolling a big sheet of dough for the top, I decided to cutout festive stars for the holiday, although any shape would work. You could even make a lattice crust for the top if you want to get fancy!
The filling was a combo of fresh mixed berries sweetened naturally with orange juice and honey/maple syrup. Since fresh berries don’t always get hot enough to burst in the oven, sometimes the filling doesn’t get saucy enough for my taste. For this reason I made a thick berry filling by cooking part of the berries on the stove with some starch before mixing in the rest of the fresh whole berries. This ensures that the final filling is nice and thick, yet still has bites of whole berries.
Before baking the pie, I brushed all of the exposed dough with an egg wash and then sprinkled a bit of turbinado sugar on top. The egg wash gives the crust a nice golden color, but is totally optional. Keep in mind though, without the egg most of the crust will stay light in color.
This pie was so good, y’all! The crust was perfectly tender, the filling wasn’t too sweet and the hint of citrus complemented the berries really well. We topped our squares with a bit of whipped coconut cream, but it would be great with vanilla ice cream or by itself with a big glass of almond milk (my fave!). I hope you enjoy this pie as much as we did! If you make this, be sure to tag me and #wifemamafoodie on Instagram so I can see your pies! Seeing your creations makes me so happy!
- 5 cups all purpose flour

- 1⅔ cup palm shortening
or butter.
- 2 tablespoons honey
, maple syrup
, or coconut sugar
- ⅓ - ⅔ cup ice cold water, a little more may be needed
or butter.
, 
, or 
- 1 egg
- 1 tablespoon water
- 1-2 tablespoons turbinado sugar
, optional
, optional- 8 cups mixed berries, divided (I did 5 cups of blueberries & blackberries and 3 cups mixed raspberries, blackberries, and strawberries)
- ½ cup maple syrup, honey or a combo of both, or more to taste (can also use cane sugar)
- ½ cup orange juice
- 5 tablespoons cornstarch or arrowroot
- pinch of salt
- 4 cups all purpose 1 to 1 gluten-free flour (I used Bobs Red Mill Gluten-Free 1-to-1 Baking Flour
)
- 1 cup tapioca flour
(tapioca helps with the elasticity, but can also use additional gf all-purpose flour)
- 2 teaspoons salt
- 1⅔ cup palm shortening, grass-fed butter or a combo of both
- 2 tablespoons coconut sugar
, honey or maple syrup
- 1½ tablespoons distilled white or apple cider vinegar
- 2 eggs (Helps dough hold together. Can omit, but dough will be more crumbly. Extra water will be needed if omitted.)
- ⅓ - ⅔ cup water ice cold water, a little more may be needed
)
(tapioca helps with the elasticity, but can also use additional gf all-purpose flour)- Combine the flour and salt in a large mixing bowl. Add the palm shortening or butter and mix in with a pastry blender until mixture is crumbly and no large clumps of oil are left. Mix in the sweetener and add water slowly, adding just enough to make dough soft and flexible but not wet. If dough is crumbly when you roll it out, it needs more water. Continue to add water until dough is nice and pliable.
- Chill for 30 minutes to overnight. Before rolling, remove dough from the fridge and let sit for 10-15 minutes on the counter.
- Take ½ of the dough and roll it between two pieces of parchment paper or plastic wrap to keep it from sticking to the pin. Roll it 2–3 inches larger than your pan. Since we're using a 10x15x1-inch baking sheet (could also use a 12x17x1) try to roll it into a 13–18 inch (ish), ⅛ inch thick rectangle. If it's larger that's okay. We'll need to use the leftover scraps for the top.
- If you rolled dough on parchment paper, use the paper to invert the dough into the pan and press the dough against the sides and into the corners of the pan. Add scraps of dough to any areas that may be short and press together. Trim the edges and add extra dough to the reserved half. Refrigerate the dough in the pan while preparing the filling.
- Combine the flours and salt in a large mixing bowl. Add shortening or butter and blend into the flour with a pastry blender until mixture is crumbly and no large clumps of fat are left. Mix in the sweetener, vinegar, and the egg. Add water slowly, adding just enough to make dough soft and flexible but not sticky.
- Divide dough in half, cover and refrigerate for 10 or 15 minutes. Roll larger half in between two pieces of parchment paper or plastic wrap into a ⅛-inch rectangle 2-3 inches larger than your pan. Since we're using a 10x15x1-inch baking sheet (could also use a 12x17x1) try to roll it into a 13–18 inch (ish), ⅛ inch thick rectangle. If it's larger that's okay. We'll need to use the leftover scraps for the top.
- Place the rolled dough into the pan and press the dough against the sides and into the corners of the pan. Add scraps of dough to any areas that may be short and press together. Trim the edges and add extra dough to the reserved half. Refrigerate the dough in the pan while preparing the filling.
- Place 5 cups of the berries into a large saucepan along with the ½ cup honey/maple syrup. (Since raspberries and strawberries are more delicate, I usually leave those out. But it doesn't really matter either way) Combine orange juice with the cornstarch and a pinch of salt and stir into the berry mixture. Turn the heat up to medium-high, cover with a lid and allow the berries to come to a simmer, stirring occasionally. Continue to cook for a few minutes, until the mixture begins to thicken. Use a wooden spoon to break up some of the berries and release their juices. Remove from the heat and stir in remaining 3 cups of berries (You can also reserve some to put over the top of the filling). Let mixture cool while cutting out the shapes for the top. Add additional sweetener, if necessary, to suit your taste.
- Preheat oven to 375F. Roll out the remaining dough about ⅛-inch thin. Use *cutters of your choice to cut out as many shapes as possible (cut close together) and place them on a pan lined with parchment paper.
- Gently re-roll the scraps one more time and cut as many shapes out as possible. Keep in mind, the more you work with the dough (with all-purpose flour) it can cause too much gluten to develop creating a tough dough. If you don't want to cut out shapes, you can make a lattice top or roll out another full sheet to cover the entire pie. If you cover the top with a full crust, be sure to cut slits in the dough to release steam.
- After you have cut out all of the shapes for the top, it's time to assemble the pie.
- Take your pan of crust out of the refrigerator. Pour filling into the crust and place cutouts onto the filling in any manner you choose.
- Beat together 1 egg with 1 tablespoon of water. Brush egg wash onto all exposed parts of the pie crust—the cutouts and along the edges. Sprinkle with turbinado sugar. Keep in mind that if you don't top with egg wash, the pie crust won't brown much.
- Place pan into the oven on the middle rack and bake for 40-50 minutes. Check the crust after 25-30 minutes and cover any areas that may be getting too brown with aluminum foil. Bake just until until filling is bubbly and crust is golden brown.
- Remove and let cool completely before cutting into squares.

- Gluten-free flour blends vary and so will the results. Keep in mind it's not as elastic as regular all-purpose flour and can break apart easily. I recommend a mix with xanthan gum to help with the elasticity, but it's not required. The egg and butter both help to keep the dough together better. I've tried gluten-free flour with all coconut oil and no egg and the crust is still delicious, just more crumbly.
- You can easily half the recipe to make a deep dish pie in a regular pie pan.
- I like the mixture of berries, but you can choose to use all blueberries or blackberries instead.
- If dough begins to crumble when rolled out, that means it's too dry and more cold water needs to be incorporated into the dough.
- You can use different shaped cutters to make the dough for the top, but I don't recommend using tiny cut-outs (1-inch cutters) as they can burn easily. Feel free to also cut long strips for a lattice top or cut out another large rectangle to put a full top crust on the pie. Just remember to cut slits across the top for the steam to escape.
- The egg wash gives the dough a glossy golden brown finish. You can also use cream or leave it plain, but crust will stay a light color.

This is basically the same recipe I have used for years, except I replace about a tablespoon or two of the oj with fresh lemon juice and add a bit of lemon zest. But I never thought to keep the strawberries and raspberries separate until the very end. Wow, did it make a difference!!! The heat of the mixture cooked them just enough to brighten the flavor, but not get mushy, and it took this filling to a whole new level. Thanks for the tip, I will do all my berry fillings this way from now on!!
OMG lady! This rocks!! I want to try the recipe!!:)
