What are Sweet Potatoes?
Sweet potatoes come from the morning glory family. It has large, starchy, sweet-tasting, tuberous roots that are packed with vitamins and minerals. Considered a root vegetable, the sweet potato is only distantly related to the potato.
Sweet potatoes have an elongated shape with a tapered end and smooth skin that may range in color from red, brown, purple, yellow, orange, and beige. Its interior flesh, on the other hand, may range in color from beige to white, purple, orange, yellow, violet, pink, and red.
There are two main types of sweet potato grown in the U.S. (and the Yam is not one of them).
That’s right, the yam is NOT a sweet potato (but more on that in a second).
- Firm sweet potatoes. these guys have tan skin and pale, off-white flesh. It is said that firm sweet potatoes still remain firm and somewhat waxy, even after cooking. I doubt it’s quite this black and white as I have not experienced this when I cooked lighter versions of sweet potatoes.
- Soft sweet potatoes. Copper skin and deep orange flesh. These are the sweet potatoes that we probably think of when we think about Thanksgiving sweet potato casserole.
What is the difference between a sweet potato and a yam?
Catching the difference between a sweet potato and a yam can be quite tricky if you don’t know what to look out for. But, if you take one thing away from this post (aside from how to bake a sweet potato, I hope), remember this- the yam and the sweet potato are not the same.
Put another way – sweet potatoes are not a type of yam (and vice versa). The two are completely different tuberous root vegetables that come from a flowering plant.
In fact, all those “yams” you see in the market probably aren’t yams at all.
Common U.S. Grocery Store Labeling-
- Yam. This is probably a soft sweet potato with copper skin and deep orange flesh.
- Sweet potato. This is probably a firm sweet potato with tan skin and pale, off-white flesh.
So, where’s the…Yam?
It’s pretty tough to find real deal yams in the U.S. But, you never know! Keep those eyes peeled. Native to Africa and Asia, yams have a cylindrical shape with blackish, brown, bark-like skin. The flesh of a yam ranges from white to purple, or red.
How to Make a Baked Sweet Potato
To bake sweet potatoes simply,
Step 1. Preheat oven.
Preheat oven to 425 degrees F and line a large rimmed baking sheet with parchment paper or foil. Spray lightly with nonstick cooking spray.
Step 2. Prepare your sweet potatoes.
Wash and scrub each sweet potato and dry thoroughly. Don’t skip the drying part! This will prevent your sweet potatoes from steaming (rather than baking).
Transfer your sparkly clean (and dry!) sweet potatoes to your prepared baking sheet. Use a knife or a fork and stab each sweet potato at least 6-7 times over the surface of the potato (this will vary depending on the size of your potato).
Step 3. Bake.
Transfer your baking sheet to the oven and bake for approximately 30 minutes. Rotate the pan 180 degrees to ensure even cooking and bake for an additional 15-30 minutes, or until you see some of the natural sugars have started to caramelize, ooze out from the fork punctures, and a fork or knife is easily inserted into the thickest part of the potato.
Step 4. Serve.
Remove the baking sheet from the oven and allow your baked potato to rest for 5 minutes before slicing open and seasoning with salt, pepper, butter, or maple syrup if desired.
Viola! That’s it! Easy, right?!
How to bake sweet potatoes in foil
To bake sweet potatoes in foil,
- Follow instructions 1-2 as outlined above (no need to line your baking sheet with foil or parchment paper though).
- Wrap each sweet potato individually in aluminum foil and place on top of your baking sheet.
- Bake and serve by following instructions 3 and 4 above.
So, you’re basically doing the same thing as you would without foil, simply wrap each in aluminum foil before baking.
Personally, I prefer potatoes that have not been baked in foil. This is all about personal preference as sweet potatoes that are not wrapped in foil have crispy skin whereas those that are cooked in aluminum foil have softer skin.
How Long to Bake Sweet Potatoes?
The length of time it will take to bake a sweet potato isn’t an exact science. It depends on two main factors- oven temperature and size of the potato.
The potatoes shown in these images took approximately 40-45 minutes at 425 degrees F. Larger potatoes or a lower oven temperature would take a much longer amount of time. Use this as a rough guide-
- 75+ minutes at 375 degrees F
- 60-75 minutes at 400 degrees F
- 45-60 minutes at 425 degrees F
How Many Calories in a Baked Sweet Potato?
One 3.5 ounces (100-gram) baked sweet potato with skin (no additional toppings) contains approximately 89 calories (source).
- Calories: 89
- Water: 75%
- Protein: 2 grams
- Carbs: 20.1 grams
- Sugar: 6.4 grams
- Fiber: 3.3 grams

The truth is, sweet potatoes are incredibly good for you. Here’s the nutritional takeaway.
- One cup (200-grams) provides more than half of your daily vitamin C and nearly 800% of recommended Daily Value (DV) of vitamin A. Each plays a vital role in the immune system, while vitamin A also helps support healthy skin, vision, and organ function.
- Rich in antioxidants – especially the orange and purple varieties – which help protect your body against cancer and disease-causing free radicals (source) (source).
- Manganese. One cup delivers one-third of your daily intake of manganese, a mineral needed to produce the amino acid proline which is essential for the production of collagen and wound-healing (source).
- High in fiber. Yes, sweet potatoes are a starchy vegetable, BUT, they are also loaded with fiber. Sweet potatoes contain two types of fiber: soluble and insoluble fiber (source). Your body cannot digest either type, making them slower to digest, and preventing a spike blood sugar levels.
- They help regulate blood pressure. One cup (with skin) provides 950 mg of potassium. Potassium helps eliminate excess sodium and fluid from our body, which, as a result, lowers blood pressure and reduces strain on the heart (source).
Now, will eating a whole bunch of baked sweet potatoes make you super skinny? Probably not.
Tips and Tricks
Bigger isn’t better. Here’s the thing, the bigger and rounder your sweet potatoes, the longer they will take to bake and the more likely you will end up with a sweet potato that is not baked evenly. The fat guys do not necessarily mean more soft and fluffy evenly baked inside. Look for long, uniform, skinny sweet potatoes.
Thoroughly wash and dry before baking. Seriously, guys. Dry your potato.
Line your baking sheet with foil or parchment paper and lightly spray with non-stick cooking spray. When you cook sweet potatoes they will ooze out their natural sweet caramelized sugars. Sugars like to solidify and stick to things…like baking sheets. Along the same lines, unless you plan to wrap them in aluminum foil, always place your potatoes on a baking sheet.
Add Some Toppings. Although butter and a pinch of salt will forever be my favorite topping, here are a few other fun ideas to mix things up:
- Browned butter and maple syrup.
- Sour cream, guacamole, and green onions.
- Pulled pork – more specifically, this apple cider pulled pork.
- Marshmallows, pecans, and butter.
- Shredded chicken – like this shredded salsa chicken or shredded buffalo chicken.
- Or, go extra crazy and pile on a big scoop of melty hot buffalo chicken dip or BBQ Chicken Dip.
- Chili! You can even add sausage to the middle and imagine it’s a super loaded chili dog!
How to Serve Baked Sweet Potato
The wonderful thing about baking sweet potatoes is that they can be enjoyed in so many different ways!
As a side, sweet potatoes taste awesome with beef, chicken, pork, and seafood, or veggie dishes. For example, shredded buffalo chicken, Instant Pot pork tenderloin, or Cajun shrimp.
Leftover baked sweet potato? Mash them and turn them into mashed sweet potatoes or blend them into soups or muffins!
Of course, you can always stuff em’. Stuff with all your favorite shredded meats, sauces, leftovers.
Of course, if you’re not into all of that, one of my favorite ways to enjoy this humble, yet super delicious vegetable is with a tablespoon of butter. That’s it.
How to Store Sweet Potatoes
Some practical (though very helpful) info for you guys on how to store these tubers:
Raw and uncooked – Potatoes will keep for a surprising amount of time when they are,
- Kept in a cool, dry, dark, and well-ventilated place.
- Kept out of the refrigerator and away from direct sun.
- Consider storing in the garage (not in the summertime), basement, or cellar. It is also recommended that you avoid storing sweet potatoes with fruits or vegetables such as onions, bananas, and apples as they can cause them to rot faster.
Cooked and baked – Simply transfer to a sealed container or wrap tightly with foil and transfer to the refrigerator for up to 3-4 days. You may also freeze your for up to 3 months.

- Naturally vegan, gluten-free, and dairy-free.
- Nutrition information is an estimate for 1 medium potato. See full post for a more detailed calculation of calories and nutrition.
- The best sweet potatoes for baking are the longer, thinner sweet potatoes. They cook faster and more evenly than the big, fat round ones.
- Wash and scrub each sweet potato and dry thoroughly. Use a knife or a fork to stab each sweet potato at least 6-7 times (this will vary depending on the size of your potato).
- Transfer potato or potatoes to a microwave-safe plate. Microwave for 5 minutes (for 1 sweet potato) plus an additional 2 minutes for each additional sweet potato (for example, 3 sweet potatoes will take approx. 9 minutes depending on size and shape). Rotate halfway through cooking.

My store has them wrapped in plastic u put in microwave very good but baking in oven is prob. Better.

PERFECT 😋😋😋
I made myself 1 yam tonight.
Thanks Eva, I am glad it worked out well for you!
I’m the only one in my household who likes sweet potatoes, so I bake 5 or 6 at a time, skin and mash them, and put the results in jumbo cupcake holders in a muffin tin, top each with a square of aluminum foil, and when they are cool, put them in the freezer.
When frozen, I transfer them to a large plastic box, and I’m set for 3- 4 weeks. I found your recipe helpful in being sure of my timing. Thank you.
If you were to use a meat thermometer, at what temperature would you take the potatoes out of the oven?
Hi Laura,
Good question. A quick google search gave me an internal cooking temperature of 210F for a sweet potato, but not to go over that temperature.
Thanks for the tutorial, the sweet potatoes came out perfecto!
I never did see the explanation of the difference between a yam and a sweet potato.
Hi Mary,
See section halfway through named: “What is the Difference Between a Sweet Potato and a Yam?” 🙂
Great explanation and recipe for a perfect sweet potato… now I just need to procure some real yams!!
Jessica,
Thank you for your candid recipe of baking sweet potatoes. Yes yes YES sweet potatoes are great in muffins making them more moist and flavorful. I highly recommend Martha White’s Honey Bran muffin mix that yields to blueberries, chopped apples and of course sweet potatoes. Keep up the good work gal!
Sweet potato was wonderful thanks a lot
Nice to meet you too !!!
