Sweet Potato and Meringue Tart Recipe

This sweet potato and meringue tart recipe is the elevated cousin to the pumpkin pie. It features a thin and buttery tart crust, a rich spiced sweet potato filling and soft pillows of toasted whipped meringue.

The sweet potato gives this tart a lovely flavor and texture while the spices make this taste like a holiday classic! The addition of fully marshmallow like toasted meringue on top takes this tart over the top in a delicious way!

This tart can be made the day of or a few day before. If you want the meringue to be at it’s peak, then I would suggest adding that onto the tart the day of or the day before you are planning to serve this tart.

The meringue on this tart is completely cooked through because this recipe is made by pouring a hot sugar mixture into whipped egg whites, resulting in a cooked and delicious, marshmallow like meringue. As opposed to the meringue that you would need to bake for it to be fully cooked.

Pumpkin pie spice is a warm and aromatic blend of spices and consists of a combination of ground cinnamon, nutmeg, ginger, cloves, and sometimes allspice. The exact ratios of the spices can vary depending on brand and regional variations. It gives it a nice balance of sweet and spicy notes and creates a rich and fragrant taste experience. Any brand you use will work great for this recipe.
