Step 1

Preheat the oven to 375ºF.

Step 2

Roll out one half of the pie dough on a floured work surface until it is a 12-inch diameter circle.

Step 3

Transfer the dough sheet to a 9-inch pie plate. Work the dough gently into the shape of the pan.

Step 4

Add the cherry pie filling in an even layer.

Step 5

Dot the top of the pie filling with the pieces of butter.

Step 6

Add the top pie crust, either as a lattice or a solid top. If you use a solid top, cut 4-6 vent holes.

Step 7

Fold the edges under and crimp in your desired style.

Step 8

Combine the egg, water, and salt in a small bowl and beat well.

Step 9

Brush the egg mixture over the top crust.

Step 10

Sprinkle it with coarse sugar.

Step 11

Place the pie pan on a baking sheet. Bake in the preheated oven for 50-55 minutes or until the filling is bubbling for at least 5 minutes and the crust is golden brown. Check the pie after 25 minutes, as you may need to cover the edges to prevent burning.

Step 12

Remove from the oven and let cool for 4 hours up to overnight before slicing.
