How Do You Know When Sweet Potato Pie is Done?

This is a tough question to answer because sweet potato pie will most likely look underdone when it is actually done.

Like cheesecake, sweet potato pie will jiggle slightly in the center when finished. But the key is that the edges of the pie will be firm.

Moreover, the pie should read 175 degrees Fahrenheit when read with an internal temperature taker when finished. If you don’t have a food thermometer, you can use a knife. The knife should be moist but come out clean when inserted in the center of the pie.

Still not convinced? Do your best to simply follow the recipe. If the recipe recommends you take the pie out after a certain amount of time, do it, even if it looks slightly underdone. This will prevent you from overcooking and ruining your grandma old fashioned sweet potato pie recipe.

Can You Overcook a Sweet Potato Pie?

Yes, it is possible to overbake a sweet potato pie.

To prevent this, simply follow the directions set for your sweet potato pie recipe, even if the pie seems a bit jiggly in the center.

Signs of an overcooked sweet potato pie include:

  • Cracking in the Filling of the Pie
  • Burnt Pie Crust Edges
  • Overly Tough Filling
  • Spongy Custard
  • Eggy Tasting

Why Did My Sweet Potato Pie Crack? How Do I Keep My Sweet Potato Pie From Cracking?

Sweet potato pies can crack due to over-cooking. It does so because the eggs in the custard mixture stiffen when cooked, causing separation in your luscious custard filling.

To prevent this, the best thing you can do is to avoid overbaking the pie.

Still, even if your pie does crack a bit, your pie is likely still edible assuming you didn’t bake it for much over the recommended amount of time as specified in your recipe.

Can Sweet Potato Pie Sit Out Overnight?

It isn’t advised that you allow sweet potato pie to sit out overnight, or even for more than a few hours. Because sweet potato pie contains milk and butter, it needs to be refrigerated only a couple of hours after having sat out to keep it fresh.

Remember that sweet potato pie is a softened dessert. Therefore, the filling should resemble the texture of pumpkin pie once done baking. Understandably, this can make it difficult to gauge whether or not the pie is actually done. Read on to learn more about how to accurately determine whether or not your sweet potato pie is fully cooked through.
