- Okinawan Sweet Potatoes – Softer, sweeter, and often used in Hawaiian and Japanese cuisine.
These unique potatoes are not just about color—they’re packed with antioxidants and fiber, making them a great choice for healthy and flavorful meals.

Cooking Methods for Purple Sweet Potatoes
Roasting Purple Sweet Potatoes
Roasting is a popular method to enhance the natural sweetness and earthy flavor of purple sweet potatoes. To prepare, preheat your oven to 425°F (218°C). Wash and peel the potatoes, then cut them into uniform cubes or wedges to ensure even cooking. Toss the pieces in olive oil, salt, and your choice of seasonings—such as rosemary, thyme, or smoked paprika. Spread them evenly on a baking sheet lined with parchment paper, ensuring they don’t overlap.
Roast for approximately 25-30 minutes, flipping halfway through, until they are tender inside and crispy on the edges. This method caramelizes the sugars, resulting in a rich, sweet flavor that pairs well with various dishes.
Boiling and Mashing
Boiling is an excellent technique, especially if you’re planning to mash the purple sweet potatoes. Begin by peeling and cutting the potatoes into equal-sized chunks. Place them in a pot and cover with cold water, adding a pinch of salt. Bring the water to a boil over medium-high heat, then reduce to a simmer. Cook for about 15-20 minutes, or until the potatoes are easily pierced with a fork.
Drain the water and return the potatoes to the pot. Mash them using a potato masher or electric mixer, adding butter, cream, or coconut milk for a creamy texture. Season with salt, pepper, and a dash of nutmeg or cinnamon for added warmth. This creamy mash serves as a delightful side dish or a base for other recipes.
Baking Whole Purple Sweet Potatoes
Baking whole purple sweet potatoes is a simple method that preserves their nutrients and natural flavors. Preheat your oven to 375°F (190°C). Thoroughly wash and scrub the potatoes to remove any dirt. Pierce each potato several times with a fork to allow steam to escape during baking.
Place the potatoes directly on the oven rack or on a baking sheet lined with foil to catch any drips. Bake for 45-60 minutes, depending on the size of the potatoes, until they are tender and yield easily to gentle pressure. Once done, let them cool slightly before serving.
Baked purple sweet potatoes can be enjoyed on their own, with a pat of butter, or as a component in various recipes.

Purple Sweet Potato Fries
Transforming purple sweet potatoes into crispy fries offers a colorful twist on a classic favorite. To prepare, preheat your oven to 425°F (218°C). Cut the washed and peeled potatoes into thin strips, aiming for uniformity to ensure even cooking.
In a large bowl, toss the fries with olive oil, salt, and seasonings like garlic powder, paprika, or cayenne pepper for a spicy kick. Arrange the fries in a single layer on a baking sheet lined with parchment paper, ensuring they don’t touch. Bake for 20-25 minutes, flipping halfway through, until the fries are golden and crisp.
For added crispiness, consider using an air fryer set at 400°F (204°C) for about 15 minutes, shaking the basket midway. Serve these vibrant fries with your favorite dipping sauce for a delightful snack or side dish.
Stuffed Purple Sweet Potatoes with Chickpeas
Stuffed purple sweet potatoes make for a hearty and nutritious meal. Begin by preheating your oven to 400°F (204°C). Wash the potatoes and pierce them several times with a fork. Place them on a baking sheet and bake for 45-60 minutes, until tender.
While the potatoes bake, prepare the filling by sautéing onions and garlic in olive oil until translucent. Add cooked chickpeas, spinach, and a blend of spices such as cumin, coriander, and turmeric. Cook until the spinach wilts and the mixture is heated through.
Once the potatoes are done, let them cool slightly before slicing them open lengthwise. Gently fluff the interior with a fork, then spoon the chickpea and spinach mixture into each potato. Drizzle with tahini sauce and sprinkle with fresh parsley or cilantro for garnish.
These stuffed potatoes are not only visually appealing but also packed with protein and fiber, making them a satisfying main course.
Purple Sweet Potato Gnocchi
Creating gnocchi from purple sweet potatoes adds a vibrant hue and subtle sweetness to this classic Italian dish. Start by baking the potatoes at 375°F (190°C) for about an hour, until soft. Once cooled, peel and mash them until smooth. Combine the mashed potatoes with flour, a beaten egg, and a pinch of salt, mixing until a soft dough forms.
On a floured surface, divide the dough into sections and roll each into a long rope about 1/2 inch thick. Cut the ropes into bite-sized pieces and, if desired, roll each piece over the tines of a fork to create ridges. Bring a large pot of salted water to a boil and cook the gnocchi in batches. They are done when they float to the surface, usually after 2-3 minutes. Remove with a slotted spoon and toss with your preferred sauce, such as a sage-infused brown butter or a light tomato basil sauce. The striking color and delicate flavor of the purple sweet potato gnocchi make it a standout dish for any occasion.

How to Select and Store Purple Sweet Potatoes
Choosing the Best Sweet Potatoes
When selecting purple sweet potatoes, look for ones that are firm, smooth, and free from cracks or bruises. The skin should be vibrant and unblemished, as this indicates freshness. Avoid any potatoes that have sprouted or appear soft, as they may be past their prime.
Different varieties, such as Stokes Purple Sweet Potatoes and Okinawan Sweet Potatoes, may have slight differences in taste and texture. Stokes purple potatoes are denser, while Okinawan sweet potatoes tend to be slightly sweeter and softer.
Proper Storage Tips
Storing purple sweet potatoes correctly ensures they remain fresh and flavorful for weeks.
- Do not refrigerate raw sweet potatoes – Cold temperatures can alter their texture and flavor, making them tough and dry.
- Store in a cool, dark place – Keep them in a pantry, cellar, or dark cabinet with good airflow. A temperature of 50-60°F (10-15°C) is ideal.
- Keep them away from moisture – Excess humidity can cause mold or sprouting. Store them in a paper bag or basket rather than plastic bags.
For cooked purple sweet potatoes, refrigerate them in an airtight container for up to 5 days. To freeze, mash or cube them first, then store in freezer-safe bags for up to 3 months.
