What is a slab pie?

Slab pies are a type of pie that is baked in a sheet pan, as opposed to in a traditional pie recipes made in a pie pan. A sheet pan pie is especially perfect for serving a large crowd.

Slab pies can be made with any type of fruit, but my favorite combination is a berry slab pie made with fresh raspberries, blueberries, and blackberries. Not only are they easy to make and adaptable to any flavor combination, but they also look beautiful when served on their own or with some ice cream or whipped cream on top.

How to make a Lattice Crust on pie?

There are all sorts of recipes for lattice crust pies, but I’m going to share my favorite method with you. Start by rolling out your pie crust on a floured work surface. Then use a pizza cutter or sharp knife to cut strips of pie crust that are about 1/2 inch wide.

Lay half of the strips across the top of your pie, spacing them evenly apart. Weave the remaining strips over and under the first set of strips, alternating between going over and under. Trim off any excess dough from the edges of your pie.

And then crimp edges to seal them shut. You can either brush the top of your pie with some beaten egg white or milk and sprinkle with coarse sugar.

Can I use frozen berries in a berry slab pie?

Yes! Instead of using fresh fruit, frozen will do just fine. Just make sure that the berries are frozen solid before you add them to the crust. If they’re not frozen, they’ll release too much juice You may also need to increase the baking time by a few minutes.berry slab pie
