What is a purple sweet potato?

It's a variety of sweet potato with violet flesh, colored by anthocyanin antioxidants instead of the beta-carotene found in orange sweet potatoes. Popular varieties include Okinawan, Stokes Purple, and Molokai.

How do you cook purple sweet potatoes?

Roasting at 400°F for 40 to 45 minutes gives the best caramelized flavor, though boiling, steaming, and air frying all work well depending on what texture you're going for.

Where can you buy purple sweet potato?

Asian grocery stores carry it most consistently and usually at the best price. It also shows up seasonally at Whole Foods, specialty grocers, farmers markets, and online.

Can dogs eat purple sweet potato?

Yes, in moderation, as long as it's cooked plain with no salt, butter, or seasonings, and the skin is removed. Check with your vet first if your dog has diabetes or kidney issues.

Is purple sweet potato healthier than regular sweet potato?

They're nutritionally similar overall, but purple sweet potato contains higher levels of anthocyanin antioxidants, while orange sweet potato is higher in beta-carotene. Neither is strictly "healthier" — they just offer different beneficial compounds.

Does purple sweet potato taste different from orange sweet potato?

Yes, slightly. Purple sweet potato tends to be less sweet and a bit denser and starchier, closer to a regular potato in texture, while orange sweet potato is sweeter and softer when cooked.

Can you eat the skin of a purple sweet potato?

Yes, the skin is edible and adds fiber, though many people peel it for a smoother texture in dishes like mash or purees. If you're roasting it, leaving the skin on is perfectly fine.

Purple Sweet Potato: How to Cook It (2026 Guide)

Description

Cubed purple sweet potato roasted until caramelized, finished with a honey-lime drizzle and fresh cilantro.

Ingredients

Scale

2 large purple sweet potatoes, peeled and cubed
2 tablespoons olive oil
1 tablespoon honey
1 tablespoon fresh lime juice
½ teaspoon salt
¼ teaspoon black pepper
2 tablespoons chopped fresh cilantro (optional, for serving)

Instructions

Preheat the oven to 400°F and line a baking sheet with parchment paper.
Toss the cubed purple sweet potato with olive oil, salt, and pepper until evenly coated.
Spread the cubes in a single layer, making sure they aren’t touching, for the best caramelization.
Roast for 35 to 40 minutes, flipping halfway through, until fork-tender and lightly caramelized at the edges.
Whisk together the honey and lime juice in a small bowl while the sweet potato finishes roasting.
Remove from the oven and drizzle immediately with the honey-lime mixture while still hot.
Top with fresh cilantro if using, and serve warm.

Notes

Cutting the cubes evenly is the single biggest factor in how well this turns out — uneven pieces mean some will burn while others stay underdone. For a naturally sweeter result without added honey, cut the pieces slightly smaller so more surface area caramelizes.
