Apple Slab Crumb Pie Recipe

Make this easy pie to feed a crowd.

Slab pies are super popular at the moment. Why not? It’s the perfect way for non-pie makers to make great looking pies that can feed a large number of people without spending all day in the kitchen. The beauty of these types of pies is that they are  adaptable to almost any type of filling: pumpkin, berries, apples, etc. And, it’s perfectly fine to use store bought crust for this pie.  This pie is so easy to make, you’ll never purchase a pie again.

Lay the pie crusts, stacked one on top of the other on a lightly floured surface or on a silicone baking mat. Roll it into a rectangle that will fit into your baking sheet. If it’s not perfect, no worries. Cut off the excess around the edges and use them to fill in thin spots on the cookie sheet.
