Japanese Sweet Potato Pie Recipe

Japanese sweet potatoes: These are the star of the dish, known for their purple skin and yellow flesh, offering a sweeter and more complex flavor than regular sweet potatoes.

Sugar: Adds sweetness to the pie, balancing the natural flavors of the sweet potatoes.

Milk: Provides creaminess and helps to create a smooth filling.

Butter: Adds richness and helps to bind the ingredients together.

Vanilla extract: Enhances the overall flavor with a subtle vanilla note.

Salt: A pinch of salt helps to balance the sweetness and enhance the flavors.

Pie crust: The base of the pie, which can be either pre-made or homemade, providing a crisp and flaky texture.

When mashing the sweet potatoes, ensure they are completely smooth to avoid any lumps in your pie filling. Using a potato ricer or a food processor can help achieve a silky texture. Additionally, make sure the butter is fully melted and the milk is at room temperature before mixing them into the sweet potato mixture to ensure even incorporation.

• japanese sweet potatoes - Substitute with regular sweet potatoes: Regular sweet potatoes have a similar texture and sweetness, though they may be slightly less starchy.

• Allow the Japanese sweet potato pie to cool completely at room temperature. This prevents condensation from forming inside the storage container, which can make the crust soggy.
• Once cooled, cover the pie tightly with plastic wrap or aluminum foil. Alternatively, you can place it in an airtight container to maintain its freshness.
• Store the covered pie in the refrigerator. It will keep well for up to 4 days. When ready to serve, you can enjoy it cold or reheat individual slices in the microwave for about 20-30 seconds.
• For longer storage, consider freezing the pie. Wrap the cooled pie in plastic wrap, then a layer of aluminum foil to prevent freezer burn. Label it with the date to keep track of its storage time.
• Place the wrapped pie in the freezer. It can be stored for up to 2 months. When you’re ready to enjoy it, transfer the pie to the refrigerator and let it thaw overnight.
• To reheat the entire pie, preheat your oven to 350°F (175°C). Remove the plastic wrap and foil, then place the pie on a baking sheet. Cover the edges of the crust with foil to prevent over-browning. Bake for about 15-20 minutes, or until warmed through.
• If you prefer to reheat individual slices, place them on a microwave-safe plate and cover with a damp paper towel. Microwave on medium power for 1-2 minutes, checking frequently to avoid overheating.
