What Are Purple Sweet Potatoes?
Purple sweet potatoes are a fascinating and nutritious variety of sweet potatoes distinguished by their strikingly vibrant, deep purple flesh. Unlike their orange counterparts, they possess a slightly denser, drier texture and offer a unique, subtly sweet, and earthy flavor profile. This gorgeous color isn’t just for show; it’s a testament to their rich antioxidant content, making them a superfood in their own right. Despite their distinct appearance, cooking purple sweet potatoes is remarkably similar to preparing other potato varieties, offering versatility in the kitchen.
There are several common types of purple sweet potatoes, each with its own characteristics:
- Okinawan Sweet Potatoes: Originating from Japan but widely celebrated in Hawaii, these potatoes feature a light tan or off-white skin that belies their intensely deep purple interior. They are known for a mild, slightly nutty flavor and a relatively dry texture once cooked, making them ideal for mashing or baking.
- Stokes Purple® Sweet Potatoes: Grown primarily in the United States, Stokes Purple sweet potatoes boast a vibrant purple skin that matches their brilliant purple flesh. They tend to be slightly sweeter than Okinawan varieties, with a pleasant nutty undertone and a moister texture, making them excellent for roasting or frying.
- Ube: While often confused with purple sweet potatoes due to its similar color, ube is actually a type of yam. Popular in Filipino cuisine, ube is traditionally used in a wide array of sweet desserts, known for its distinct vanilla-like flavor and creamy texture. It’s important to distinguish ube from purple sweet potatoes, as their culinary applications can differ.
Understanding these distinctions can help you choose the right purple sweet potato for your culinary adventure, though for most savory applications, Stokes Purple and Okinawan varieties can often be used interchangeably with fantastic results.
Why Choose Purple Sweet Potatoes?
Beyond their captivating color, purple sweet potatoes are nutritional powerhouses that offer significant health benefits. Their vibrant hue comes from anthocyanins, powerful antioxidants also found in blueberries and red cabbage. These compounds are known for their anti-inflammatory properties and potential roles in protecting against chronic diseases. Compared to their orange and white counterparts, purple sweet potatoes often contain higher levels of antioxidants, making them an excellent choice for a health-conscious diet.
Nutritionally, they are a fantastic source of dietary fiber, which aids digestion and promotes a feeling of fullness. They also provide essential vitamins and minerals, including Vitamin C, potassium, and manganese. Their natural sweetness makes them a delightful alternative to traditional potatoes, suitable for both savory and sweet dishes. Incorporating purple sweet potatoes into your diet is a delicious way to boost your intake of beneficial nutrients while enjoying a unique flavor and texture. Their earthy sweetness pairs beautifully with a range of seasonings and toppings, offering endless culinary possibilities.
Mastering the Art of Cooking Purple Sweet Potatoes
Cooking purple sweet potatoes is a straightforward process, similar to other potato varieties, but with a few tips to bring out their best. Whether you prefer them baked, roasted, air-fried, or boiled, achieving that perfect tender interior and flavorful exterior is key. Here’s a general guide to preparing these magnificent root vegetables:
- Preparation is Key: Always start by thoroughly washing your purple sweet potatoes. Scrub their skins under cool running water to remove any dirt or residue. While many prefer to leave the skin on for added nutrients and rustic flavor, you can certainly peel them if that’s your preference.
- Choose Your Method: Purple sweet potatoes are incredibly versatile and shine in various cooking methods. Consider the texture and flavor profile you’re aiming for.
- Boiling: For a soft, easily mashable potato, boiling is an excellent choice. Place whole, cleaned potatoes in a large pot and cover them with cold water. A generous pinch of salt in the water enhances their flavor. Bring the water to a boil, then reduce the heat to a simmer. Cook until the potatoes are fork-tender, typically 30-40 minutes for medium to large potatoes.
- Baking (Oven): Baking yields a creamy interior and a slightly crispy skin. Preheat your oven to 400°F (200°C). Lightly rub the potatoes with olive oil and sprinkle with salt and pepper. Place them directly on the oven rack or a baking sheet. Bake for 60-90 minutes, depending on size, until the skin is crisp and a fork easily glides into the flesh. For extra tender results, you can wrap them in foil before baking.
- Air Frying: For a quicker cooking time and a delightfully crisp exterior, the air fryer is your friend. Rub the potatoes with a little oil and season with salt. Air fry at 400°F (200°C) for 35-45 minutes, making sure to flip them halfway through to ensure even cooking and crispness. They’re done when they’re tender inside and have a nicely browned, crisp skin.
- Serve and Enjoy: Once cooked, allow the purple sweet potatoes to cool slightly before slicing or serving whole. This allows the internal moisture to redistribute, resulting in a more tender and flavorful experience. They are delicious on their own or topped with your favorite savory or sweet accompaniments.

Equipment
- Cosori Air Fryer
- Cast Iron Dutch Oven
- Air Fryer Oil Spray Bottle
Ingredients
- 2 purple sweet potatoes (Mine weighed about 4 ounces each.)
- Cooking oil spray (I use olive oil.)
- Salt and pepper to taste
Instructions
Air Fryer Instructions
- Rub the sweet potatoes with olive oil. I use an oil spray bottle to spritz both sides and rub the oil in thoroughly. Optionally, sprinkle salt over the sweet potatoes for enhanced flavor.
- Place the prepared sweet potatoes in the air fryer basket. Air fry at 400°F (200°C) for 35-40 minutes, or until the sweet potatoes are soft and tender. To check for doneness, pierce a sweet potato with a fork; it should slide in easily.
Oven Instructions
- Preheat your oven to 400°F (200°C).
- Rub the sweet potatoes with olive oil. I prefer an oil spray bottle for even coverage. Spritz both sides and rub the oil in. You can also sprinkle salt over the sweet potatoes at this stage. (For an even softer result, you can wrap the potatoes in foil before baking).
- Place the sweet potatoes on a baking sheet. Bake for 60-90 minutes, or until they are soft when pierced with a fork. The cooking time will vary based on the size and thickness of your potatoes.
Stovetop/Boiling Instructions
- Place a large pot on the stove over high heat. Ensure the pot is large enough to accommodate the sweet potatoes, you may need to trim them to fit. Add enough water to completely submerge them.
- Bring the water to a rolling boil. Cook the sweet potatoes for 30-40 minutes, or until they are soft and easily pierced with a fork.
- Optional tip: For easier skin removal, transfer the boiled sweet potatoes to a bowl of cold water for 5-8 minutes after cooking. The skin will then peel off effortlessly.

Frequently Asked Questions About Purple Sweet Potatoes
Yes, you absolutely can eat the skin of purple sweet potatoes! It’s packed with fiber and nutrients, and many enjoy its slightly earthy texture. You don’t have to peel them, especially if you’re roasting, air frying, or making fries, as the skin adds flavor and helps them hold their shape. Just ensure they are thoroughly scrubbed clean before cooking.
The stunning purple color of these sweet potatoes comes from a natural pigment called anthocyanins. These are powerful antioxidants also found in other vibrant foods like blackberries, blueberries, and red cabbage. A study published in The Journal of Nutrition highlights their numerous health benefits, making these colorful spuds a nutritious choice.
Purple sweet potatoes offer a unique culinary experience. They typically have a rich, nutty flavor and a wonderfully creamy texture when cooked. Many find them to have a subtle sweetness that is less intense than orange sweet potatoes, often described as more earthy. Their inherent flavor means they don’t usually require as much added salt as a russet potato.
Several factors can contribute to a bitter taste in purple sweet potatoes. Not all varieties are created equal; some, like Okinawan, naturally possess a drier and more earthy flavor compared to the milder sweetness of Stokes Purple potatoes. If you’re accustomed to the sugary taste of orange sweet potatoes, purple varieties might seem a little bland or even slightly bitter in comparison.
Another reason could be immaturity or insufficient curing. Sweet potatoes need a curing period after harvest to fully develop their natural sugars. If harvested too early or not cured long enough, they may retain an earthy or bitter taste instead of mellow sweetness. Finally, overcooking can cause bitterness. Purple sweet potatoes are often starchier and denser. If roasted or boiled for too long, their natural sugars can burn or undergo undesirable chemical changes, leading to a harsh or bitter aftertaste. Monitor cooking times closely to avoid this.
Checking for spoilage is important to ensure a pleasant culinary experience. Look for these signs:
- Soft or mushy spots: If areas feel squishy or sunken, it’s likely starting to rot.
- Wrinkled or shriveled skin: While a little dryness is normal, if the entire potato appears shriveled and dehydrated, it’s past its prime.
- Mold or black spots: Any visible mold, especially around the ends or in deep cracks, means it should be discarded. Small dark spots can be cut away, but widespread or deep discoloration indicates spoilage.
- Strong off smell: Fresh sweet potatoes have a very mild aroma. If you detect a sour, fermented, or mildew-like smell, it’s spoiled.
- Discoloration inside: When cut open, the flesh should be a vibrant deep purple or violet. If it looks gray, green, or slimy, it has likely gone bad.
Purple sweet potatoes are becoming more accessible, though they might require a bit more searching than orange varieties:
- Major Grocery Stores: Large supermarket chains like Whole Foods, Sprouts, Trader Joe’s, and Wegmans often stock them, especially during fall and winter. Check the organic or specialty produce sections.
- Local Farmers Markets: These are excellent sources for fresh purple sweet potatoes, particularly in regions known for diverse or specialty crops. Don’t hesitate to ask vendors about availability or if they can source them.
- Asian Grocery Stores: Stores specializing in Japanese, Filipino, or Hawaiian cuisine frequently carry Okinawan sweet potatoes or ube, which, while distinct, share a similar color profile.
- Health Food Stores: Natural food stores and co-ops focusing on organic and non-GMO produce are good places to find Stokes Purple sweet potatoes and other varieties.
It’s always a good idea to call ahead to your local store or market to confirm availability before making a special trip.
To maintain their freshness, store purple sweet potatoes in a cool, dark, and well-ventilated place, like a pantry or cellar. Avoid refrigerating them, as cold temperatures can alter their flavor and texture, leading to a harder core when cooked. Stored properly, they can last for several weeks.
Purple sweet potatoes are incredibly healthy! They are rich in powerful antioxidants called anthocyanins, which give them their vibrant color and offer anti-inflammatory benefits. They’re also an excellent source of dietary fiber, promoting digestive health, and provide essential vitamins and minerals like Vitamin C, potassium, and manganese. They contribute to overall well-being and are a great addition to a balanced diet.
