❓ Recipe FAQs
Nope! There is no need to boil or cook your potatoes beforehand. These sweet potatoes will be perfectly cooked in the oven!
Yes! Sweet potato skins are tasty and nutritious. You can always choose to leave the skin on if you like.
This is a personal preference as to whether or not you want to soak them. Soaking them helps to release some of the starches from the surface, causing them to become extra crispy.
If you want to soak them, put them into a bowl of ice water for an hour or two and then rinse them off and pat them dry before continuing with the recipe.

I absolutely love this recipe. I lived alone and have added this to my “Often” list. I buy one large sweet potato and make it for just myself. Get two side dish meals from that and it is delicious and healthy! Thank you.

Très bon cependant je n’aimais pas les patates douces au départ. Vous m’avez réconcilié avec elles. Merci à vous. (Very good however I did not like sweet potatoes at first. You reconciled me with them. Thank you.)
