No matter the size, you can bake a sweet potato in the oven following this simple recipe for a hands-off mealtime win.
Baked Sweet Potatoes
The oven is the perfect way to bake sweet potatoes (IMO). It’s low-effort, and the result is the kind of perfectly cooked sweet potato where the skin crisps up, pulls right off, and the inside is fluffy and soft.
Unless it’s summer, in which case my husband says it heats up the house, so I roast them whole in the air fryer or air fry them cubed when I need them quick. My teens microwave them while my mother-in-law cooks them in the Instant Pot. Everyone does their thing!
How to Roast a Sweet Potato in the Oven
- Prep the sweet potatoes by washing them well and piercing them a few times with a fork. This lets the heat in through the meat and prevents them from bursting.
- Bake the sweet potatoes in a preheated oven on a baking sheet (lined for easy cleanup since sometimes they stick to the metal), until they’re easy to pierce with a fork and the skin is visibly separated. Depending on the size of your sweet potato, at 425F, this can take 30 to 45 minutes.
Should You Wrap Sweet Potatoes in Foil?
Wrapping them in foil makes cleanup easy, but it steams them and leaves the skin soft. For crispy skin and caramelized edges, bake them unwrapped and use foil or parchment to line the pan.
How Long to Bake a Sweet Potato
Baking time for sweet potatoes depends on their size. Take a look at this chart below for approximate times at 425F.
| Sweet Potato Width | Bake Time |
|---|---|
| 3 inches | 25 minutes |
| 4 inches | 30 minutes |
| 5 inches | 45 minutes |
| 6 inches | 60 minutes |
Knowing When They’re Done
Baked sweet potatoes are done when a knife or fork slides easily through the center; if there’s resistance, bake for another 5 minutes and check again.

Once they are ready, you can keep it simple and top them with butter, or stuff them up for a full meal. These Buffalo chicken stuffed sweet potatoes are my favorite, although there are unlimited toppings for sweet potatoes that you can use.
