🛒 Ingredients for Purple Sweet Potato Pie

This recipe uses simple pantry ingredients that are easy to find in most American kitchens.

Ingredients

1 large purple sweet potato (Murasaki, Ube, Okinawa, or Beauregard)
2 eggs
1 egg yolk
3 teaspoons pumpkin spice blend
1 teaspoon vanilla extract
1 (14 oz) can sweetened condensed milk
1/4 cup water

Each ingredient plays an important role in building the pie’s flavor and texture.

🍠 Choosing the Best Purple Sweet Potato

The star ingredient of this recipe is the purple sweet potato. Several varieties work well in pies.

Okinawan Sweet Potato

Okinawan sweet potatoes have a pale outer skin and deep purple flesh. They are slightly less sweet but very creamy when cooked.

Ube

Ube is a purple yam commonly used in Filipino desserts. It has a slightly vanilla-like flavor and vibrant color.

Murasaki

Murasaki sweet potatoes have purple skin and white flesh, but they still create a delicious filling with mild sweetness.

Beauregard

This is a common sweet potato variety that may sometimes produce a deeper orange or purple hue.

All of these varieties will produce a smooth and flavorful pie filling.

🧄 Why Sweetened Condensed Milk Works So Well

Sweetened condensed milk is the secret to achieving the pie’s silky texture and balanced sweetness.

Unlike regular milk or cream, condensed milk is thick and sweet, which helps:

Create a creamy consistency
Add sweetness without extra sugar
Blend perfectly with the mashed sweet potatoes

It also makes the filling easy to mix and foolproof to bake.

🔪 Preparing the Sweet Potato

Before making the filling, the sweet potato needs to be cooked and mashed.

Step 1: Bake the Sweet Potato

Preheat your oven to 400°F (200°C).

Wash and pierce the sweet potato with a fork. Place it on a baking sheet and bake for 45–60 minutes, or until soft.

Baking intensifies the sweet potato’s natural flavor.

Step 2: Cool and Mash

Allow the potato to cool slightly, then peel off the skin.

Mash the flesh in a bowl until completely smooth. You should have about 1 to 1½ cups of mashed sweet potato.

🍳 How to Make Purple Sweet Potato Pie

Follow these simple steps to create a smooth and perfectly baked pie.

🥣 Step 1: Prepare the Pie Crust

If using a store-bought crust, place it in a 9-inch pie dish.

You can also use homemade pie crust if you prefer.

For best results, lightly pre-bake (blind bake) the crust for about 10 minutes at 350°F. This helps prevent a soggy bottom.

🍠 Step 2: Make the Filling

In a large mixing bowl, combine:

mashed purple sweet potato
2 eggs
1 egg yolk
pumpkin spice blend
vanilla extract
sweetened condensed milk
water

Use a whisk or electric mixer to blend everything until smooth and creamy.

The mixture should be thick but pourable.

🥧 Step 3: Fill the Pie

Pour the filling into the prepared pie crust.

Use a spatula to smooth the surface.

🔥 Step 4: Bake the Pie

Bake at 350°F (175°C) for about 40–45 minutes.

The center should be set but slightly jiggly when gently shaken.

Avoid overbaking, as the filling will continue to firm up as it cools.

❄️ Step 5: Cool the Pie

Let the pie cool completely on a rack.

Cooling allows the filling to set properly and improves the texture.

For best flavor, refrigerate the pie for at least 2 hours before serving.
