Ingredients you’ll need to make this sweet potato pie recipe

Sweet potatoes, pie dough, butter, spices, sugar in white bowls on white countertop to make a pie
  • Sweet Potatoes: We get these babies roasted up until super tender and caramelized bringing out all that rich natural flavor.
  • Oil: We rub the potatoes in this so to promote more even uniform baking.
  • Salted Butter: That creamy rich flavor can’t be beat when mixed into the smooth filling.
  • Granulated Sugar: Sweet potatoes are naturally sweet but we gotta up that sweetness to give dessert vibes.
  • Eggs: These help bind our filling ingredients together giving that perfect custardy smooth texture.
  • Vanilla Extract: Just a splash is add the perfect amount of aromatic essence and depth of flavor.
  • Evaporated Milk: Big mama’s liquid of choice was the PET brand. It gives such richness and creaminess to the filling.
  • All-Purpose Flour: We add just a wee bit to let that pie filling set up perfectly.
  • Spices: Big mama never used cinnamon so you won’t find it in this recipe. She loved her some nutmeg though. That warm spice plus a pinch of salt brings all the flavors together.
  • Pie Crusts: We go with homemade here but trust that you can also use store-bought to keep this even easier.

Recipe Substitutions

  • Sugar: To add a touch of molasses, use brown sugar instead of granulated. You can even make your own brown sugar.
  • Butter: If you don’t have salted, grab unsalted and just add a bit more salt to the mix.
  • Evaporated Milk: Use heavy cream or half-and-half instead to make the filling richer and creamier.
  • Flour: Just use cornstarch as a replacement and you turn the entire filling gluten-free in the process.

Recipe Variations and Additions

  • Spice it Up: Add a touch of cayenne to the batter to give it a kick.
  • Gluten-Free: Besides replacing the flour with cornstarch or a gluten-free all purpose flour, make sure you use a gluten-free crust recipe as well.
  • Vegan: Use vegan butter, plant-based milk and flax eggs as replacements in the recipe. You can also replace the butter in the dough with vegan butter.
  • Crust Switch Up: Go with a graham cracker crust to add a different texture and sweetness to the mix.

Expert Tips and Tricks for making the best homemade sweet potato pie

  1. Roast Those Potatoes: Some sweet potato pie recipes call for boiling the potatoes but I find that baking them brings out more natural sweetness without making them watery in the process.
  2. Go Room Temp: Make sure those eggs, butter and milk are room temp so they create a super smooth well-mixed pie filling.
  3. Keep It Smooth: Getting rid of those annoying strings on your beaters will ensure you end up with the silkiest pie ever y’all.
  4. Just a Jiggle: It’s all good if your filling still has a little jiggle before you take the pie out. It will continue to set as it rests.

How to store & reheat sweet potato pie

It’s best to store your homemade sweet potato pies in the fridge. I like to cover mine with plastic wrap then with foil. When you are ready to serve, just slice and let it come to room temp for about 20 minutes or heat in the microwave if you want a warm slice.

How long will Southern sweet potato pie last in the fridge?

It should last for about 3-4 days in the fridge.

Can I freeze?

Oh for sure boos! In fact, my big mama’s sweet potato pie stores great in the freezer. Wrap super well in plastic wrap then in foil. It should last in the freezer for up to 2 months.

Frequently asked questions

Can you make this Southern sweet potato pie ahead?

Yep you know it boos. In fact, it will taste better if you make it ahead since it lets all those flavors mingle and blend better the longer it sets. Make up to 2 days ahead of serving. You can just store in the fridge until you are ready to serve it up.

Why is my sweet potato pie runny?

It may be because you didn’t bake it long enough boo. We also add flour in so the filling gets a little extra help setting up too.

Why is my homemade sweet potato pie crust soggy?

You probably didn’t prebake it boo. Adding that extra step ensures against a soggy crust at the end of the day.

Sweet Potato Pie Recipe

My big Mama's Sweet Potato Pie recipe is over 100 years old, and it's so good you'll be lickin' the pie tin!
5 from 4 votes
Course: Dessert
Servings: 2 9 inch pies, 12 servings each

Ingredients

  • 4 medium sweet potatoes 44 ounces total
  • 2 tbsp vegetable oil or any neutral oil like canola
  • 1 cup salted butter room temperature
  • 2 1/2 cups granulated sugar
  • 4 large eggs room temperature
  • 2 1/2 tsp vanilla extract
  • 1 cup evaporated milk PET brand was big mama's fave brand
  • 2 tbsp all-purpose flour
  • 2 tsp ground nutmeg
  • pinch of kosher salt
  • 2 pie crusts either homemade pie crust or store-bought

Instructions

  • Preheat the oven to 400F. Place the rack in the middle position. Prepare sheet pan by lining with parchment paper.
  • Scrub, rinse, and dry sweet potatoes. Stick a fork all over each potato multiple times to allow steam to escape.
  • Rub oil on the surface of each potato. Place on the prepared pan and bake for about 50 minutes, flipping the potatoes halfway through. Use a toothpick or skewer to check for doneness; the toothpick should slide easily into the potato with no resistance. If not done, bake for a few more minutes.
  • Meanwhile, line two 9-inch glass pie plates with my homemade pie dough (which has been pre-baked) or store-bought dough in the refrigerator until ready for use.
  • Remove potatoes from the oven and let cool slightly on parchment paper, about 10 minutes. As the potatoes are still hot, carefully remove the skin from the potatoes. You should have 4 cups of mashed potatoes. (You can gently press on them with a fork or whisk and measure them into a large measuring cup.)
  • While warm, place the potatoes in the bowl of a stand mixer, fitted with the whisk attachment. Turn the mixer on medium low for about 20 seconds then stop and remove the whisk and rinse the fibrous strings from the whisk. Repeat this two or three times, each time rinsing the strings from the whisk. We want this pie to be unbelievably smooth!
  • Add butter to warm potatoes and mix on medium until butter has absorbed, about 1 minute. Slowly add sugar on medium low and mix until incorporated. Scrape down the bottom and sides of the bowl as needed.
  • If you see more strings at this step, remove them. Add the eggs one at a time, waiting for each to incorporate into the batter.
  • While the mixer is on low, slowly add vanilla and evaporated milk. Scrape bottom of the bowl to ensure batter is mixed evenly.
  • Finally, add the flour, nutmeg, and salt and mix into the batter.
  • Pour 3 ยพ cups of batter into each prepared crust (it may seem like the crust is too full but it is fine). Bake for 10 minutes on 400 F, then reduce oven temperature to 325 F and continue baking until the middle of the pie is set (there will be a slight jiggle but this is fine), about 45 minutes. The filling will rise slightly during baking, but not spill over.
  • Remove from the oven and let sit until it comes to room temperature, about 30-40 minutes. Then place in the refrigerator until chilled and set, about 3 hours.
  • Serve room temperature or slightly warmed.
