How to Use Sweet Potatoes

Wondering all about how to use sweet potatoes in the kitchen? We’re answering your top questions, including how to cook sweet potatoes in the air fryer, how to make grilled sweet potatoes, and boiling sweet potatoes, as well as the nutrition benefits of sweet potatoes, in this guide.

What are sweet potatoes? Despite their name, these orange-fleshed tubers—which may also be found in white, yellow, or purple varieties—are not related to the potato, nor the yam, a name they’re often mistakenly called. The actual yam is a rough and starchy root vegetable usually imported from the Caribbean and is nothing like the sweet potato, which traces back 10,000 years in South America. There are about 400 varieties of sweet potatoes in different skin and flesh colors, some shaped like a potato, others long and slender with tapered ends. Common varieties like Garnet or Japanese Purple will have different textures (firm and dry or soft and moist) and degrees of sweetness.

Sweet Potato Nutrition Benefits

Sweet potatoes are packed with health potential, thanks in large part to their cache of beta-carotene (found in orange-fleshed sweet potatoes), which is a precursor to vitamin A in the body. One medium sweet potato packs a whopping 438% of the recommended daily value of vitamin A! Sweet potatoes are also packed with vitamin C, manganese, pantothenic acid, vitamin B6, biotin, potassium, fiber, vitamins B3, B1, B2, and phosphorus. Whew! All from a humble little root. Bring purple sweet potatoes to the table for a burst of anthocyanins—the same phytochemicals found in blueberries—which are powerful antioxidant and anti-inflammatory compounds linked with disease protection.

Growing Sweet Potatoes

When to harvest sweet potatoes? Peak season is October through December, but they are available all year in most supermarkets. Select small and medium sweet potatoes for a sweeter, moister flesh. Choose those with smooth, firm, and blemish-free skin. The deeper the color of the skin, the richer it likely is in beta-carotene (or anthocyanins for purple varieties). How long do sweet potatoes last? Store in a cool, dark, well ventilated place, but never refrigerate them for best results—you should get 3-5 weeks shelf-life.

It’s also a wonderful topping for a Shepherd’s Pie or filling for Potato Pancakes.
