🍠 What Are Purple Sweet Potatoes?

Purple sweet potatoes are a type of sweet potato with a deep purple flesh that is often used in cooking and baking. They are also known as purple yams, Japanese sweet potatoes, or Okinawan sweet potatoes.

They are a rich source of vitamins, minerals, and antioxidants, and are known to have a slightly sweet and nutty flavor. In addition to their health benefits, purple sweet potatoes are often used in recipes as a natural food coloring, as the rich purple color can add a vibrant hue to a variety of dishes.

🧂 Ingredients and Substitutes

Purple sweet potato fries: Use nice firm, fresh purple sweet potatoes. I prefer these fries with peeled potatoes, but you can make them unpeeled if you prefer.

Olive oil: I find extra virgin olive oil works well and also contributes to the flavor slightly. If you do not have olive, a different oil like avocado oil, coconut oil or grapeseed oil are other great choices.

Smoked paprika: Be certain to use the smoked variety of paprika in this recipe. Regular sweet or hot paprika will give these fries a completely different flavor.

Garlic powder: Garlic powder works extraordinarily well in combination with smoked paprika. I do not recommend omitting this ingredient.

Salt: I find one teaspoon of salt to be just about perfect when using two medium purple sweet potatoes, but feel free to adjust based on the size of the potatoes you use and your own personal taste preference. This is a great recipe for using coarse sea salt in!

❓ Frequently Asked Questions

Do purple sweet potatoes taste different?

Yes, purple sweet potatoes have a slightly different taste than regular orange sweet potatoes. They have a slightly sweeter and nuttier flavor compared to the more earthy taste of regular sweet potatoes. The texture of purple sweet potatoes is also slightly firmer and less starchy.

Are purple sweet potatoes healthier than regular sweet potatoes?

Yes, purple sweet potatoes are generally considered to be healthier than regular sweet potatoes. They are higher in antioxidants, specifically anthocyanins, which give them their vibrant purple color. Anthocyanins have been linked to several health benefits, such as reducing inflammation and improving heart health. Additionally, purple sweet potatoes are also a good source of fiber, vitamins, and minerals, including vitamin C, vitamin A, and potassium.

Can purple sweet potato fries be made in an air fryer?

Yes. After tossing the fries in oil and spices, place them into the air fryer basket in a single layer and air fry at 400°F for about 15 minutes of cooking time, or until golden brown, giving a shake about halfway through. Air frying does result in slightly crispier fries.
