FREQUENTLY ASKED QUESTIONS:
Sweet Potato Slab Pie is a sweet custard pie made with cooked and mashed sweet potatoes. The mashed sweet potatoes are combined with sugar, half and half and warm spices then baked in a pie crust that has been pressed into a large baking pan. The taste and texture is very similar to pumpkin pie.
In America, we use the words yam and sweet potato to describe sweet potatoes. Nearly all canned yams are actually sweet potatoes in America. However, a true yam has a dark brown skin and a light interior – almost like a russet potato. Sweet Potatoes have a lighter, reddish skin and the interior is orange in color. Sweet Potatoes are native to North America. Yams have a lot more starch than sweet potatoes as well. True yams are actually a little harder to find in the United States than are sweet potatoes.
I do not recommend using canned yams in this particular recipe. I love to use canned yams/sweet potatoes but because we have a pie crust in this recipe, even when drained, the yams will contain too much water and the outcome of the crust and filling will not set up as thick as we’d like.
Absolutely! If you aren’t a fan of refrigerated pie crusts you can make your own favorite recipe. If you do make your own crust, you will need to ensure you make enough to cover the entire sheet pan.
We like to microwave them for this recipe as it is the quickest and less messy method but you could also bake them or boil them. To boil, I peel the potatoes, cut them up in chunks and boil in water until fork tender. Some people think the best way to make sweet potatoes is to bake them. I’ve tried it all different ways and they all taste the same way to me so the preparation is up to you.
When the internal temperature reaches 175 degrees F. Another way to tell is when the top looks set and isn’t liquid. There will be just the slightest jiggle in the middle (but not a lot). Pull it out and it will continue to set up as it cools.
Yes definitely. Cool the pie completely. Wrap the pie pan in plastic wrap and then a layer of foil. If you can, place slices in a large freezer bag, separated with parchment paper and place in the freezer where it will keep for up to 2 months. To defrost, place in your refrigerator overnight.
Yes. This is a custard type pie so it does need to be kept refrigerated. Just wrap the pie in plastic wrap and it will keep in the refrigerator for 2-3 days.
INGREDIENTS NEEDED: (SEE RECIPE CARD BELOW FOR THE FULL RECIPE)
- refrigerated pie crusts

HOW TO MAKE A SWEET POTATO SLAB PIE:
Preheat the oven to 450 degrees F. Spray a half sheet (18×13-inches) pan with nonstick cooking spray.
On a lightly floured surface, unroll 3 pie crusts and place the crusts end to end and roll out to a 19 x 14-inch rectangle.
Fit the crust into the prepared pan. Fold extra crust underneath and crimp if desired. Poke bottom and sides of crust with a fork (this keeps it from puffing up too much). Bake for 7 to 9 minutes or until light golden brown. Remove from the oven and set aside.
Reduce oven temperature to 375F degrees.
Using a blender, hand mixer, food processor (or by hand), combine the mashed sweet potatoes, brown sugar, eggs, half-and-half, vanilla extract, cinnamon and ginger until smooth as possible. There may be a few little lumps and thats okay.
Pour filling mixture into pan. Bake 25 to 28 minutes or until the center of filling is set, remove from the oven.
Cool on the cooling rack until cool then refrigerate for at least 1 hour.
Meanwhile, prepare the crust for decoration. Remove the last pie crust from the refrigerator and roll it out. Using different size round cookie cutters cut out shapes. This step is optional.
Bake on an ungreased cookie sheet for 11-15 minutes until lightly golden, arrange on the pie.
Cut and serve!
