The United States is also a large producer and ranks in the top 10 countries of sweet potato production. Popular states that grow sweet potatoes are North Carolina, California, Mississippi, and Louisiana.

Sweet potatoes are extremely healthy! They are packed with fiber and micronutrients. They are highest in vitamin A and the antioxidant, beta carotene. Just one serving of 100 grams provides your entire recommended daily value of vitamin A.

Other vitamins sweet potatoes have include vitamin C, potassium, manganese, vitamin B6, vitamin B5, and vitamin E.

Overall, sweet potatoes can limit your chances of vitamin A deficiency, improve blood sugar regulation

How to Roast Sweet Potatoes in the Oven: What to Bake Sweet Potatoes At?

You can bake sweet potatoes at any temperature from 275°F to 425°F, depending on how much time you have. In most recipes you’ll read, they’ll ask you to bake them anywhere between 350°F to 425°F.

Baking them at a temperature lower than 350°F will require them to stay in the oven much longer. They will bake for as long as two and a half hours as compared to roughly 40 minutes at a higher temperature. Sweet potatoes of any size will take anywhere from 30-60 minutes in the 350°F to 425°F temperature range. The advantage of baking sweet potatoes at lower temperatures is that you can bring out more of their natural sweetness and get a creamier texture.

In this oven roasted sweet potatoes recipe, I bake them at 400°F. It’s a nice middle-range temperature that doesn’t require the sweet potatoes to take too long in the oven, while still caramelizing the sugars.

How Long to Roast Sweet Potatoes Whole?

Roasting whole sweet potatoes take roughly 40-60 minutes. Determining how long your sweet potatoes take to roast largely depends on their size and the temperature you roast them at.

Roasting larger potatoes will take longer. Roasting them at a higher temperature will make the roasting process go faster. Roasting potatoes at any temperature above 400°F will keep your potatoes roasting for less than an hour.

What to Line Your Baking Sheet With?

I recommend lining the baking sheet on which you roast your sweet potatoes with foil or a silicone baking mat. Don’t use parchment paper or leave your pan uncovered. If you use parchment paper, you will burn it, and that could affect the sweet potatoes. If you leave your pan unlined, it will be much harder to clean off as the sugars from the potato will drip onto the pan and caramelize. By leaving your pan uncovered, you’ll risk degrading it faster, and it won’t keep new for as long.

By using foil, you can quickly discard the sticky foil while leaving your pan completely clean. No scrubbing is required. However, if you want to be more environmentally friendly, use silicone mats. Silicone mats will provide a nonstick surface that will make cleaning them a lot easier and faster. All you need to do is run them under warm water with a soapy sponge and the sticky sugars from the roasted sweet potatoes will slide right off.

Should You Wrap the Sweet Potatoes in Foil?

No, you don’t need to wrap sweet potatoes in foil. I recommend not doing this. However, it’s completely optional, and up to you. Wrapping your sweet potatoes will steam them more than roast them. The sugars won’t caramelize as much, and they won’t be as sweet.

I think what’s important to remember when you’re learning how to roast sweet potatoes in the oven, is knowing when to be flexible and how to adjust the cooking process based on your needs and preferences, which will help you go from a beginner cook to a master pro. For example, knowing you don’t have to wrap potatoes in foil to get a beautifully roasted sweet potato or change the temperatures it bakes at.

Seasoning for Roasted Sweet Potatoes

There is a multitude of seasonings you can use for this oven roasted sweet potatoes recipe. I don’t recommend putting seasonings on the potatoes before they bake unless you plan on eating the skins. If you want to eat the potatoes with the skins on, and want some extra flavor, I recommend rubbing your potatoes in olive oil and sprinkling them with salt and pepper before baking. Or you can use the list of seasonings below before or after your potatoes bake.

Other seasonings you can use:

  • Smoked Paprika
  • Everything But the Bagel Seasoning
  • Cayenne
  • Turmeric
  • Garlic Powder
  • Onion Powder
  • Cajun Seasonings
  • Nutmeg
  • Cinnamon
  • Coconut Sugar
  • Brown Sugar

Yes! Cooked sweet potatoes can be frozen. If you freeze sweet potatoes, wrap them whole with plastic wrap. By wrapping them in plastic, you reduce their exposure to air. Then place them in a gallon freezer bag, and store them in the back of the freezer for up to six months.

Can You Make Roasted Sweet Potatoes Ahead of Time

Yes, you can! Make as many whole sweet potatoes as you need for the next week, and store them in an air-tight container in the fridge. I recommend making enough for no more than one week, as they could go bad if you leave them in the fridge longer.

Equipment

  • 1 baking sheet
  • oven

Ingredients
  

  • 4 medium-sized sweet potatoes see recipe notes

Instructions
 

  • Preheat the oven to 400° F.
  • Take each sweet potato, run them under cold water and scrub them with a brush or your hands to get any extra dirt off of them. Once done, pat them with a towel to dry.
  • Poke holes all around each potato with a fork. This will help reduce the cooking time and provide natural venting for the steam.

  • Next, line a baking sheet with foil or a silicone baking mat.
  • Place the potatoes on the baking sheet, and put them in the oven. Bake for 45-55 minutes, or until the potatoes are soft when pierced through with a fork or skewer.

  • Once they are done cooking, take them out of the oven and let them cool to room temperature.
    How-to-roast-sweet-potatoes-in-the-oven-done
  • If desired, once they’re cooled down, peel the skins off. During the cooking process, the skins will detach from the flesh of the potatoes, which will make it a lot easier to peel off. Just pinch a part of the skins off, which will leave a hole in the potato, put your finger underneath the skins, and slowly peel off the skins. You can also cut the potatoes in half, and grab onto the skin that way.

  • The time it takes for your sweet potatoes to bake will largely depend on their size. Small sweet potatoes can take anywhere from 35-45 minutes to bake, whereas larger sweet potatoes can take anywhere from 45-55 minutes.
