Thanksgiving just wouldn’t be Thanksgiving without a pie (or three). Every year, I churn out multiple pies because no one in my family can seem to agree on which one they like best. Some folks love classic apple, some like tart cherry and some are more cream pie people. I do what I can to please everybody, but one woman can only do so much. 

This year, I’m  cutting a few corners, kicking back and enjoying my holiday. Why? Because I can. This tri-pie sheet pan pie recipe is just what this hectic, over-the-top year called for. Three pies, baked at the same time, in one giant crust: a holiday miracle!

I used this recipe to combine my family’s favorites: Pecan, Sweet Potato and Pumpkin. I mean, if you can’t pick one flavor, you can have a little of each! 

How to Make Sheet Pan Pie

Pie recipes can be labor intensive and, when it comes to large gatherings, one pie just doesn’t make the cut. Don’t get me wrong, I love spending days in the kitchen cranking out crusts and whisking fillings but I just don’t always have the time for that. 

This large and in charge sheet pan pie combines ease with flavor! Using a store-bought crust and 3 one-bowl fillings, you’ve got a jumbo-sized pie that can feed an army. 

Here’s how it comes together: 

A long pie dough rolled out into a sheet pan

Store Bought Pie Crust- This recipe is made simple by utilizing a store-bought crust! No need to cube cold butter or pull a muscle rolling out dough, just pick up a couple packages of your preferred frozen aisle variety. Before working the dough, allow the crust about 30 minutes to an hour to defrost a bit. 

TIP: If you can’t seem to get your hands on a frozen pie crust, trying using puff pastry! Treat it the same as you would the crust (just a hair more gentle) and you have a buttery, flaky and unique pie.

Sweet Potato Pie Filling-  rich and sweet, these creamy potatoes make for a wonderfully decadent pie. Each bite is earthy, smooth and downright heavenly! An uncomplicated filling allows the natural flavor of this delicious root vegetable to shine through. 

TIP: A lot of recipes call for boiling or steaming sweet potatoes before making the filling. But, I find that both methods water-log the potatoes and make for a soupy, underwhelming filing. Bake the sweet potatoes whole, at 375 degrees for an hour, up to a week in advance of baking. 

Pecan Pie Filling- Pecan pie might just be my favorite; it’s crunchy, sticky-sweet and melt-in-your-mouth delicious. This classic filling pleases just about everyone at the function! 

TIP: Pecan pie benefits from having rested for a solid amount of time. I’d recommend allowing this pie to at least come to room temperature before serving it. Ideally, this pie would be refrigerated overnight. 

Pumpkin Pie Filling- Who doesn’t love a warm, spiced pumpkin pie? This filing is creamy, decadent and, yet, somehow still simple and light. 

TIP: Want to do something different? Trying swapping out the pumpkin puree for butternut squash! This easy swap will make for a nuttier, sweeter filling.

Leftover Storage and Reheating

To Store: I recommend cutting any leftovers into pre-portioned squares; this will make it easier to properly wrap each piece and tuck them away. Once ready to eat, you’ll be able to pop one (or however many you’ll need) out of the freezer, defrost and enjoy! 

Because this pie contains eggs, it’s important to keep it tightly-wrapped and refrigerated or frozen. Wrap each piece in a layer of plastic wrap, then either place it in an airtight container or wrap it in an additional layer of aluminum foil. A properly stored pie can be refrigerated for up to 3 days and frozen for up to 6 months. 

To Reheat: I suggest avoiding the microwave; it just doesn’t help the texture of the pastry. A conventional or toaster oven works much better. Preheat your oven to 350 degrees, line a baking sheet with foil or parchment paper, place the pie on the sheet and lightly cover with foil. Bake for 5-15 minutes, depending on the size of the slice you’re reheating. 

If you’re starting from frozen, either defrost the pie in the fridge overnight or at room temperature for 30-60 minutes.

Prep Time 45 minutes
Cook Time 50 minutes
Cool 1 hour 30 minutes
Total Time 3 hours 5 minutes
Course: Dessert
Servings: 16 servings

Ingredients

  • 4 refrigerated rolled pie crusts should be 2 boxes

For the Sweet Potato Filling

  • 2/3 cup granulated sugar
  • 5 tbsp unsalted butter room temperature
  • 1 large egg
  • 1/4 tsp vanilla extract
  • 1 2/3 cup sweet potato fully cooked and mashed
  • 3/4 tsp ground cinnamon
  • 1/4 tsp ground nutmeg
  • 1/4 tsp salt
  • 1/3 cup evaporated milk

For the Pecan Pie Filling

  • 3/4 cup light brown sugar
  • 1/2 cup light corn syrup
  • 4 tbsp unsalted butter melted and cooled
  • 1 large egg plus 1 egg yolk
  • 1 tsp vanilla extract
  • 2 cups pecans roasted and roughly chopped
  • kosher salt

For the Pumpkin Pie Filling

  • 1 1/2 cup pumpkin puree
  • 1/4 cup evaporated milk
  • 1/2 cup granulated sugar
  • 1/2 tsp kosher salt
  • 1 large egg
  • 2 tsp pumpkin pie spice see note below

Instructions

For the Crust

  • Preheat the oven to 350 degrees F. Unroll 3 of the pie crusts on a lightly floured work surface. Stack them on top of each other. Roll out the thick, layered dough to a 15-by-21-inch rectangle. Press into a rimmed baking sheet so that the crust comes up the sides and hangs over slightly. This will be the bottom crust. Chill until ready to use, at least 30 minutes.

For the Pumpkin Pie Filling

  • Whisk together the pumpkin, evaporated milk, sugar, salt, pumpkin pie spice and the egg and in a medium bowl until smooth. Cover and set aside.

For the Pecan Pie Filling

  • Whisk together the brown sugar, corn syrup, butter, vanilla, eggs and a pinch of salt in a medium bowl until smooth. Fold in the pecans, cover and set aside.

For the Sweet Potato Pie Filling

  • Using a stand mixer or a hand held mixer, beat together the butter and sugar, then carefully add in the egg and vanilla. Once combined, add in the cinnamon, nutmeg, salt and mashed sweet potato. As the mixture begins to smooth out, gradually pour in the evaporated milk. Mix until fully incorporated, cover and set aside.

To Assemble

  • Once all fillings are made, begin assembling the pie. Remove the baking sheet with dough from the refrigerator. Using a fork, poke the pie crust about a dozen times, going all around the dough (except for the crust).
  • Using a large spatula, carefully scoop, spread and smooth each filling onto the crust. On the left side, start with the sweet potato and allow it to only take up ⅓ of the pan. Next, scoop and spread the pecan filling in the middle. Because there is a bit more liquid in the pecan mixture, it will spread a bit, do your best to control it by quickly scooping, spreading and smoothing the pumpkin mixture on the right side.
  • Bake until all pies are set and the crust on the pie is golden brown and crisp, 50 to 60 minutes.
  • Remove the pie from the oven and allow it to completely cool, about 1-1 ½ hours. Tightly cover the top with aluminum foil (or plastic wrap) and transfer to the refrigerator to set for at least 4 hours. Overnight is best.
  • Allow the pie to sit at room temperature for at least 30 minutes before serving. Slice, serve and enjoy!

Notes

If you don’t have pumpkin pie spice for the pumpkin pie filling, add 1 tsp ground cinnamon, ½ tsp ground ginger, ¼ allspice, ¼ tsp cloves, pinch of nutmeg.
*There will be leftover dough! It can be used to decorate the tops of the pies or saved for a smaller project.

  1. Omg. This is the best idea ever!! If I only wanted 2 pies in 1, I’d have to do an extra half for all the measurements, right?

  2. this is pure genius, best use of a sheet pan yet! And three separate cakes not just three cakes layered into one, love the optionallity with this, opens up a lot of potential uses, thank you!

  3. Great idea,will love to try this
    I am confused on one part of assembly instruction. Number 3 states baking 50-60 minutes until cherry and apple pie are golden,there is no apple or cherry pie in this sheet pie. Please clarify cooking time for sheet pan pies. This recipe is for pumpkin, pecan,sweet potato pies.

  4. Perfect for when you have guests with different tastes! Much easier than baking a few separate pies, and looks fun too.

  5. Oh wow! Love this! I always make a variety of pies for Thanksgiving so everyone gets their favorite. Now I don’t have to..thank you 🙂

  6. This is genius! And the best way to be able to eat all three without having to make 3 separate pies. I’m all about the pumpkin though 😉

  7. This is brilliant! How have none of us thought of this before? I’ve already bought all my pie ingredients for this Thanksgiving, but I’ll be doing this next year for sure. We do a PTA pie sale as well, and this would be idea.
