This Peach Slab Pie is full of sliced peaches swimming in a delicious mixture of cinnamon and sugar, then topped with a crisp oat topping.

OMG! This Peach Slab Pie is absolutely delicious! It's a like a combination of pie and peach crisp. My family loved it!pinterestTop it off with a scoop of vanilla ice cream and it’s a total winner!

I’ve created the best of both worlds with this super easy peach slab pie. The crust has a delightful shortbread cookie taste to it, that is similar to my Peaches and Cream Pie Bars. The topping is a delicious oat crumble that’s filled with oats, brown sugar and pecans.

Create the perfect end of summer dessert with this Peach Slab Pie!

Tips for making Peach Slab Pie:

  • I use a half sheet baking pan that measures roughly 18″ x 13″. If you don’t have one this large, you can make two smaller slab pies with all the ingredients.
  • Keep the butter for the topping cold when mixing to create a nice crumble, then bake immediately.
  • Feel free to swap out any kind of nut in the topping to your preference. Almonds and Pecans are my favorite.

This Peach Slab Pie recipe is the perfect dessert for potlucks since it can easily serve a crowd!

What type of peaches to use:

  • Toss some drained canned peaches with some sugar, cinnamon and a little flour and then pour it into the pie.
  • You can definitely use fresh peaches here. Just peel the peaches and slice them thin before tossing with the sugar mixture.
  • Frozen peaches would work as well. Toss the frozen peaches in the sugar mixture first thing and let it sit on the counter for 30 to 40 minutes before adding to the pie dough.

This Peach Slab Pie is filled with fresh peaches and topped with a crisp oat topping!

Bake the peach slab pie for about 40 to 45 minutes until the filling is bubbly and the crust is golden brown!

WOW! This Peach Slab Pie recipe is super quick to pull together and tastes like summer in each bite!

It’s especially tasty when served warm with a scoop of vanilla ice cream on top.

The warm peaches swimming in a sweet cinnamon mixture are the perfect filling to the crumbly pie crust and crisp oat topping.

One bite and you’ll be hooked!

For the Crust:

  • 1 cup butter, room temperature
  • 2 cups sugar
  • 3 eggs
  • 1 tsp vanilla
  • 4 cups flour
  • 1 tsp salt
  • 1 tsp baking powder

For the Peach Filling

  • 3 peaches
  • 1 cup sugar
  • 1/4 cup flour
  • 1/2 tsp cinnamon

For the Oat Topping:

  • 1 cup rolled oats
  • 1 cup brown sugar
  • 1/2 cup flour
  • 1/2 cup butter, cut into small pieces
  • 1/2 cup almonds


  • Preheat oven to 375 degrees F.

For the Crust:

  • Cream together butter and sugar in the bowl of a stand mixer fitted with a paddle attachment. Add the eggs one at a time, beating well after each egg. Add in vanilla.
  • In a separate bowl combine the flour, salt, and baking powder. Gradually add the dry ingredients to the wet and mix until a soft dough forms. Press into a 18" x 13" x 1" baking pan into an even layer, adding extra up the sides to form a crust.

For the Filling:

  • Place the drained peaches* in a large bowl and add 1 cup sugar, 1/4 cup flour and 1/2 tsp cinnamon. Gently stir to coat and then pour over the pie crust.

For the Topping:

  • In a separate bowl combine 1 cup oats, 1 cup packed brown sugar and 1/2 cup of flour. Use a pastry cutter or two forks to work in the small pieces of butter until the mixture resembles coarse crumbs. Stir in the 1/2 cup sliced almonds. Sprinkle the mixture over the peaches and bake for 40 to 45 minutes, or until the filling is bubbly and the topping is golden brown.
  • Cool slightly in pan on a wire rack. Serve warm or cool completely.
*if using fresh peaches: (4 lbs. or 12 medium peaches) remove peel and slice thin before tossing in the sugar mixture. If using frozen peaches toss with the sugar mixture as directed, then let stand at room temperature for 30 minutes before adding to the crust.
