Triple Berry Slab Pie

Triple berry slab pie is a sheet pan pie filled with blackberries, raspberries, and blueberries set in a pastry crust. Easy to make and serve, it’s a great dessert for a crowd. 

Pie Crust for Slab Pie

4 cups flour

3 Tablespoons sugar

1 ½ teaspoon salt

1 cup butter, cold 

½ cup vegetable shortening

½ cup ice water

Hand Method

Put flour, sugar and salt in a bowl. Mix to combine.

With a pastry cutter, cut in butter and shortening into flour mixture until it resembles coarse meal. 

Stir in ice water one tablespoon at a time, tossing with fork after each addition. (NOTE: you may not need all water—stop adding water when mixture clumps together.)

Divide dough into three equal parts. Shape 1/3 into a flat disc. Shape 2/3 into a second larger flat disc. 

Cover with plastic wrap and refrigerate for at least 30 minutes. 

Food Processor Method

Place flour, sugar and salt in bowl of food processor and pulse to combine.

Add cold butter (cut into small cubes) and shortening (cut into cubes) and pulse to cut fat into flour mixture (about 10 times). 

Add water, 1 tablespoon at a time and pulse each time until mixture clumps together. 

Continue with step 5 above.
