📝 Frequently asked questions, answers and tips:
Yes! Bake those potatoes the night before or even up to 5 days before you make this recipe. Save time when you have it. Just store the cooled potatoes in the fridge until using them.
Nope. That is up to you. I bake the potatoes and leave the skins on. But if you like the potato skins off, bake them and then scoop out the baked potato flesh. Or peel them before baking.
