Sweet potatoes are an underappreciated side dish. Too often they are associated only with large meals, or holidays.

Fried or roasted sweet potatoes can be cooked and served in different ways and seasoned in different ways. They are similar to regular potatoes in that it is hard to cook them wrong.

However, there are methods of making them go from good to great! It starts with seasoning, then goes to how you cook them.

Can you leave the skin on the potatoes instead?

For the best results we recommend you remove the skin of the potato before cutting into cubes. However, you can try leaving the skin on the potato. If you do this you will likely find better results if you do not preheat the air fryer and instead, put them in first, then start heating up the air fryer.

Can you freeze the roasted sweet potatoes?

Yes, with care, but they are best served fresh. If you do freeze them, the main thing here is to flash freeze them. After you finish cooking them, quickly get them spread out on a baking sheet and get them in the freezer. Leave them there for two hours, then remove them and place in a freezer bag for continued storage.

How do I reheat them?

You can heat them in the air fryer at 375 degrees for 4-5 minutes or until warmed through.

I made these sweet potatoes last night and was mortified because they looked nothing like the picture. But i decided to trust the process and just go with it and am so happy I did. They were amazing!!! I will be making these over and over. Thank you for this wonderful recipe.

Hi Julie! So glad they turned out, but I’m so curious about what they looked like! haha

can u still cook them the same way on the recipe if u don’t have an air fryer with the baskets?

Karly February 24, 2022 - 6:34 am

We’ve only tested this recipe in a basket style air fryer, but this should work just the same in any style of air fryer. Just use a fork to test for doneness (they’ll be soft and easily poked through) and adjust cook time if needed.

Your recipes are amazing keep them coming! I have a Cosori 5.8 and a Breville smart oven air but I must confess, I prefer my Cosori! Love your profile photo too!

Thanks, Frances! We have the Breville smart oven and like it for a lot of things – just not so much for air frying. So glad you’re enjoying the recipes! 🙂
