The healthiest ways to cook sweet potatoes are boiling or steaming, as they best preserve nutrients like beta-carotene and antioxidants while keeping the glycemic index lower, preventing blood sugar spikes. Roasting is also good if you keep the nutrient-rich skin on and use minimal healthy oil, but boiling or microwaving retains more nutrients and lowers the glycemic load more effectively. For gut health, boiling and then cooling creates resistant starch, a beneficial fiber.
Boiling them with water is one of the simplest and healthiest ways to prepare them. This method preserves most of their nutrients and their natural sweetness.
Boiling may actually retain most of the antioxidant power of sweet potatoes, compared to roasting and steaming. If we compare baking to boiling microscopically, boiling helps thin out the cell walls and gelatinize the starch, which may enhance the bioavailability of nutrients.
Sweet potato contains more carbohydrate, vitamin C and minerals than Irish potato. In the food processing methods employed, it was observed that boiling retains more carbohydrate than frying while frying retains more vitamin C and minerals than boiling.
But in the interest of maximizing flavor, texture, and convenience, which cooking method comes out on top? In the past, Kenji showed us that both low-temperature baking and sous vide cooking were reliable methods to maximize sweetness in sweet potatoes.
People with kidney problems must avoid eating sweet potatoes because an improperly functioning kidney cannot remove potassium from their body, causing high potassium levels that can be harmful to them. Sweet potatoes contain high amounts of oxalates that may increase the risk of calcium-oxalate kidney stones.
You can bake them in the oven whole or as wedges, microwave them and air fry them. Whereas microwaving is quick, baking gives them a nice crisp texture or skin. Using the air fryer for perfectly crisp sweet potato fries uses less energy and cooking time as well as oil compared with an oven.
Low-carb diets are a popular way to limit calories and lose weight. Sweet potatoes have carbohydrates, but you can still find a place for them on your plate and benefit from their nutrients.
Just one sweet potato gives you 102% of the vitamin A you need each day. This helps keep your eyes healthy as well as your immune system, your body's defense against germs. It's also good for your reproductive system and organs like your heart and kidneys.
They're notoriously high in carbs, but as it turns out, sweet potatoes can actually help manage blood sugar. “Sweet potatoes have a low glycemic index,” says Vigue. “This means that they raise our blood sugar more slowly than other carb sources, which is important for people with type 2 diabetes.”
Farmers overwhelmingly agree the best way to cook sweet potatoes is roasting or baking. Dice, toss with olive oil, salt, garlic, then roast around 400°F for 20 minutes. Baking whole or as wedges works—but roasting gives crisp edges and deeper sweetness.
Summary of differences between sweet potatoes and rice
Sweet potatoes have more vitamin A, vitamin C, vitamin B6, potassium, fiber, copper, vitamin B5, and vitamin B2; however, rice is higher in selenium and folate. Sweet potatoes cover your daily need for vitamin A, 384% more than rice.
Sweet potatoes are plenty sweet on their own.) Culinary production director Wes Martin explains why we prefer the oven to the stove: Boiling draws flavor out of the sweet potatoes and into the water, and that flavor gets washed down the drain.
Soaking the sweet potatoes removes excess starch, which allows them to crisp up easier. You will want to put them in cold water for at least 30 minutes, but the longer you can go, the better.
Since sweet potatoes are exposed to heat for a shorter time in the microwave than when they're cooked in the oven, they may actually retain more nutrients. In fact, some studies show that vegetables cooked in the microwave retain more of their water-soluble nutrients, such as vitamin C, than when they're boiled.
Is it soft, wet, oozing, squishy, discolored, or sprouting? If you answer yes to any of those questions, then toss it—your sweet potato has spoiled!
1. Spinach. Spinach is a leafy green vegetable and a great source of calcium, vitamins, iron, and antioxidants. Due to its iron and calcium content, spinach is a great addition to any meat- or dairy-free diet.
And now, for the Don't Worry list, the Clean 15 with the lowest pesticide load. This is courtesy of Dr, Andrew Weil: avocados, sweet corn, pineapples, cabbage , sweet peas (frozen), onions, asparagus, mangoes, papayas, kiwi, eggplant, grapefruit, cantaloupe (domestic), cauliflower, sweet potatoes.
Baking can cause an 80% drop in vitamin A levels—twice as much as boiling. So, “from a nutritional standpoint, boiling rather than baking can be recommended for sweet potato cooking.”
How to Boil Sweet Potatoes
Steamed or boiled sweet potatoes retain most of their resistant starch, making them a lower GI food, while roasting sweet potatoes at high heat converts more of their starch into a sugar called maltose, giving them a higher glycemic index.
