Sweet potatoes are an absolute staple in our house.
They are a canvas for a myriad of flavor combos!
And one of the best ways to cook up this starchy vegetable is as a baked sweet potato.
Not only does wrapping them in foil make for easy clean-up, but it locks in the steam for tender and fluffy potatoes!
Plus, baking is much better than boiling sweet potatoes if you want the natural sweetness to come out.
You can then load them up with fillings in these BBQ Chicken Stuffed Sweet Potatoes, or turn them into some mashed sweet potatoes, a sweet potato casserole, or a sweet potato shepherd’s pie.
How to Bake Sweet Potatoes in the Oven
Before we dive into how to cook sweet potatoes in the oven, we will first need to get them ready.
1. Rinse, Scrub, and Poke
Since these root vegetables are grown underground you will want to make sure you rinse and scrub them thoroughly before baking, especially if you plan to eat the skin.
The skin generally has more fiber than just the flesh and will give you a boost of extra nutrition.
After rinsing and scrubbing, poke holes into the sweet potato with a large fork. This step enables them to release any excess moisture while baking in the oven.
It is optional, but you can also drizzle a little oil and sprinkle some salt and pepper over each one if you’d like to eat the skin.
Expert Tip: Sweet potatoes are one of the “dirty dozen” so it is best to buy organic if they’re available.
2. Wrap Potatoes in Foil
Cut pieces of aluminum foil that are large enough to wrap each potato at least twice.
Next, roll each sweet potato in the aluminum foil.
Fold over the ends of the foil in order to completely seal the potato.
Place the wrapped sweet potatoes on a large baking sheet.
3. Bake at 400°F for 45-60 minutes.
The best temperature to cook sweet potatoes in the oven is 400 degrees Fahrenheit. This temperature is hot enough to cook the potatoes in under an hour while also not being so hot that they burn.
However, you can cook them in an oven anywhere between 350 degrees and up to 450 degrees if you have other dishes you are cooking at the same. Just make sure you adjust the cooking time accordingly.
Larger sweet potatoes will take closer to 1 hour to cook while smaller ones can be ready in as little as 40 minutes.
Meal Prep and Storage
- To Prep-Ahead: Sweet potatoes are a great meal prep side dish recipe to have on hand for busy weekdays.
- To Store: Keep in an airtight container in the refrigerator for up to 4-5 days.
- To Freeze: Seal baked sweet potatoes in an airtight container and freeze for up to 4-6 months.
- To Reheat: It is best to re-warm sweet potatoes in a 275 degree oven for 15-20 minutes, or by cutting them in half and heating in the microwave.
Baking versus Instant Pot
When I first created this Instant Pot Sweet Potato recipe I was in awe of how quickly you could cook them by using a pressure cooker.
However, I soon realized that if you want to cook more than 4 at a time, there is another way that simply can’t be beat.
So I learned how to bake sweet potatoes in the oven.
Not only can you put up to 15-20 sweet potatoes in the oven at the same time, but they also get a wonderfully crisp exterior the Instant Pot just can’t reproduce.

A microwave is the fastest way to cook a sweet potato, however baking will result in a better texture.
Oven Baked Sweet Potatoes, Boiling Sweet Potatoes, or Instant Pot Sweet Potatoes are the healthiest as they use little or no oil. But roasting them will give them the best flavor!
Expert Tips and Tricks
- Scrub a dub, dub. Remove all of the dirt before cooking, use a vegetable brush if needed.
- Poke some holes. This helps to release the juices when baking so the potato doesn’t build up pressure and potentially burst.
- Drizzle on oil. If you’re going to eat the skin for the tons of fiber add some flavor with oil, salt, and pepper.
- Width is what matters. Select similarly sized potatoes so they all cook up at the same rate.
- Test for doneness. Always check the largest potato to make sure it’s cooked through.

When you bake them wrapped in foil and you are planning on storing in refrigerator or freezer do you leave them wrapped in foil
London Brazil says
You can if you’d like, but I tend to unwrap mine and put them in a container so the oil doesn’t leak out of the foil. Totally up to you though, Denise!

Back in the 80s-90s….the instruction booklet for my microwave said to cook the potato(s) throughly but not overly then take them out and wrap in foil until use. I never thought 2x about it. But my girlfriend was all over with excitement and wanted my “secret”. Her husband wouldn’t eat micro’d potatoes , they tasted funny to him. I didn’t know that and served them with dinner. He ate them fine. I told my girlfriend it was all in his mind. So she went home and had a potato tasting contest. Which one was micro’d? He said no contest and picked the one that had not been wrapped in foil afterwards. Truth is they were micro’d together. I asked recently if one wrapped a sweet potato after microwaving in foil…..people thought I was crazy and had never heard of such a thing.

I am cooking 60 potatoes in the oven. Why do they need to be on a tray with sides? Can they just be placed on the racks?
London says
Hi Mary! Great question. I place the sweet potatoes on a rimmed sheet pan to catch any excess liquid that seeps out of the foil packets (just in case they weren’t wrapped tightly enough.) You can definitely place them directly into the oven but you might have a little cleanup to do afterwards.
