Why Purple Sweet Potatoes?

Purple sweet potatoes stand out for their striking color, but their benefits go far beyond aesthetics. They are:

  • Rich in antioxidants: The purple pigment is due to anthocyanins, powerful antioxidants that help fight inflammation.
  • High in nutrients: Packed with fiber, vitamins A and C, and potassium, they’re a healthy option for any diet.
  • Versatile in recipes: From savory dishes to sweet treats, their slightly sweet, earthy flavor adapts well to a variety of recipes.

Popular varieties of purple sweet potatoes include Stokes Purple®, Okinawan sweet potatoes, and Molokai sweet potatoes. Each has slight differences in texture and flavor, but they are all packed with nutrients and a deep purple hue.

The History Behind Purple Sweet Potatoes

Purple sweet potatoes have a rich history, particularly in places like Japan and Hawaii. Okinawan sweet potatoes are a staple in the diet of Okinawa, one of the world’s “Blue Zones” known for the longevity of its residents. In Hawaii, purple sweet potatoes, known as uala, were brought by Polynesian settlers centuries ago. The Stokes Purple® sweet potato is a relatively new variety, developed in the U.S. and grown primarily in California.

The cultural importance of these varieties is just as fascinating as their health benefits, contributing to their growing popularity worldwide. Read more about their cultural significance here.


How to Cook Purple Sweet Potatoes

There are numerous ways to prepare purple sweet potatoes, depending on your taste preferences and the dish you’re making. Below are the most popular cooking methods, each with its unique benefits.

Baking Purple Sweet Potatoes

Baking is one of the easiest ways to cook purple sweet potatoes. It’s ideal for those who enjoy the texture of baked potatoes but want a healthier, nutrient-dense option. Baking brings out the natural sweetness while maintaining the rich, earthy flavor of the potato.

Steps:

  1. Preheat your oven to 425°F (220°C).
  2. Wash the sweet potatoes thoroughly and poke holes all over with a fork.
  3. Rub each potato with olive oil for crispier skin.
  4. Bake for 40–50 minutes until soft and tender.
  5. Once baked, cut open and season with salt, pepper, or your favorite toppings.

For an extra crispy skin, you can increase the oven temperature to 450°F during the last 10 minutes of baking.

Boiling Purple Sweet Potatoes

Boiling is an excellent option for recipes like mashed sweet potatoes, soups, or stews. It’s also the best method for making sweet potato purees, which are a great base for desserts and baby food.

Steps:

  1. Peel and cube the potatoes for faster cooking.
  2. Add the cubed sweet potatoes to a large pot of salted water.
  3. Bring to a boil and cook for 20–30 minutes or until fork-tender.
  4. Drain and mash or blend as needed.

Boiling may reduce some of the nutritional content, so if you’re looking to preserve the most nutrients, consider steaming instead.

Steaming Purple Sweet Potatoes

Steaming is another way to cook purple sweet potatoes that preserves more of their vitamins and minerals. It’s a gentler process than boiling and works great for keeping the potatoes’ vibrant color intact.

Steps:

  1. Peel the potatoes if desired (the skin contains many nutrients) and cut into uniform pieces.
  2. Place the potatoes in a steamer basket over boiling water.
  3. Cover and steam for 20–30 minutes, or until tender.
  4. Serve with butter, herbs, or incorporate them into other dishes.

Steamed sweet potatoes can be used in both savory and sweet recipes. Their smooth texture works wonderfully in mashed potatoes or purees.

Frequently Asked Questions

Can I use regular sweet potatoes in these recipes?
Yes, you can substitute regular sweet potatoes in most recipes that call for purple sweet potatoes. However, there are some differences in taste and texture. Purple sweet potatoes are generally less sweet and have a denser, starchier texture compared to the more common orange sweet potatoes. While both types are versatile, the visual impact of purple sweet potatoes makes them stand out, especially in dishes where the vibrant color is key, such as pies or cakes. Using regular sweet potatoes will alter the final appearance and flavor slightly, but they will still work in most recipes.


Storing and Freezing Purple Sweet Potatoes

Once you’ve cooked your purple sweet potatoes, you can store them for later use. Proper storage ensures that they maintain their flavor and texture for several days.

  • Storing in the Fridge: Place leftover cooked purple sweet potatoes in an airtight container in the refrigerator. They will last for about 3–5 days. This method works well for prepped meal components like baked or mashed potatoes.
  • Freezing Cooked Purple Sweet Potatoes: You can also freeze purple sweet potatoes. Allow them to cool completely before freezing. Wrap them tightly in plastic wrap or place them in freezer-safe containers. They will keep for up to 3 months.

To reheat, you can use the oven or microwave. Simply thaw frozen potatoes in the refrigerator overnight before reheating.


Additional Tips for Cooking Purple Sweet Potatoes

Here are some extra tips to ensure you get the best results when cooking purple sweet potatoes:
