Peaches are one of the go-to fruits in the south. They are juicy, naturally sweet, and bring color and a burst of flavor to any dessert.

We particularly love to use them in pies or cobblers. That is why this peach slab pie is “ as sweet as a peach“!

And while we’re on the topic of slab pies, you’ll want to try this sweet potato slab as well.

All you need to know about peach crumble slab pie

A slab pie is a shallow pie made in a rimmed, rectangular baking sheet. In other words, it is a round pie’s older sibling, the bigger, improved version.

What makes it even better? It’s large enough to feed a group, which makes it ideal for a family gathering, neighborhood street party, or church potluck.

Substitutions for this recipe

This recipe uses “store bought” pie crust making for quicker and easier prep time. However, if you prefer the “from scratch” method, you can easily substitute your favorite pie crust.

Your “from scratch” pie crust might have a better flavor and texture, but store-bought is more convenient. Let time and personal preference be the deciding factor.

We are all about fresh in the south, so this slab pie calls for the use of fresh, wholesome peaches. They give the pie a sweeter taste than frozen or canned.

However, for the sake of substitution (because we know sometimes it’s necessary), you can sub frozen or canned peaches.

When using canned (drained) or frozen (thawed and drained) peaches, use in equal amounts for fresh peaches. Just remember the taste and texture will be different.

pie, whether savory or sweet, has a bottom crust. This peach crumble slab pie incorporates the best of both worlds, a bottom crust and delicious crumble topping.
