Looking for something special to bring to a Fourth of July cook-out? Check out this American Flag Pie! It’s a sheet-pan slab pie with a homemade crust, a blueberry and strawberry filling, topped with stars and stripes.
Slab pies are shallower than regular pies, but they make up for it in width. A 13 x18 sheet pan pie will easily feed 12 people, perfect for a party.
While conceivably you could use a prepackaged folded frozen pie crust (just get four of them and cut them to fit the rectangular sheet pan, and cut out the shapes), I strongly encourage you to try the home made crust recipe I’ve included for this pie.
