What Are Purple Sweet Potatoes?

Purple sweet potatoes are a variety of sweet potatoes that are deep purple in color. They contain anthocyanins, which are antioxidants that give them the pigment that's also found in red cabbage, purple carrots, blueberries, purple cauliflower and blackberries. Sweet potatoes originated in Central and South America and are grown around the world. There are varieties of purple sweet potatoes that are grown in the U.S. and Japan with purple skin or white skin.

What Do Purple Sweet Potatoes Taste Like?

Purple sweet potatoes have a mildly sweet flavor with a dense texture. They are typically starchier than orange sweet potatoes and need to be cooked longer until they're tender all the way through.

  • ¾ cup whole-wheat pastry flour

  • ½ cup all-purpose flour

  • ½ teaspoon salt

  • 8 tablespoons cold unsalted butter, cut into 1/2-inch cubes

  • 3 to 4 tablespoons ice water


  • 1 ¼ pounds purple sweet potatoes, scrubbed

  • 1 (12 ounce) can low-fat evaporated milk

  • cup light brown sugar

  • 3 large eggs

  • 3 tablespoons melted butter, cooled

  • 2 tablespoons brandy

  • 1 teaspoon vanilla extract

  • ½ teaspoon ground nutmeg

  • ¼ teaspoon ground allspice

  • ½ teaspoon salt


  1. Mix pastry flour, all-purpose flour and 1/2 teaspoon salt in a large bowl or pulse in a food processor. Cut in cold butter using a pastry blender or two knives or by pulsing in the food processor until the butter forms pebble-size pieces. Add water, 1 tablespoon at a time, until the dough is evenly moist (but not wet) and is just starting to clump together, being careful not to overmix. Pat the dough into a 5-inch disk. Wrap in plastic and refrigerate for at least 1 hour and up to 1 day.

  2. Prick sweet potatoes all over with a fork. Microwave on High until tender all the way to the center, 10 to 15 minutes. (Alternatively, place in a baking dish and bake at 425 degrees F until tender all the way to the center, about 1 hour.)

  3. Meanwhile, preheat oven to 350 degrees F.

  4. Remove the dough from the refrigerator and let stand for 5 to 10 minutes to warm slightly.

  5. When the sweet potatoes are cool enough to handle, scoop the flesh into the food processor (discard skins). Pulse until smooth. Add evaporated milk, brown sugar, eggs, butter, brandy, vanilla, nutmeg, allspice and salt. Puree until very smooth, scraping down the sides as needed.

  6. Roll the dough out on a lightly floured surface into a 12-inch circle. Transfer to a 9-inch deep-dish pie pan. Tuck the overhang under and crimp the edge with a fork or flute it between your thumb and index finger. Pour the filling into the crust.

  7. Bake the pie until puffed and just firm in the center, 50 to 55 minutes. Let cool on a wire rack for at least 30 minutes before serving.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
