Hi Rick, I don’t recommend reheating in the microwave. They will not turn out as crispy. An air fryer or toaster oven will give the best results if you can’t use the oven, but the oven for 10 minutes at 350 would work for one batch. It may take longer if you have scaled the recipe.

I use non-stick Reynolds Aluminum foil for something like this. Then you won’t have to worry about using the higher temperature.

Kate, how ‘gently reheated’? Like how long and at what oven temperature? I want to make a large batch the night before and serve them the next morning. I need to go oven for other items that morning. Thank you.

Thank you for your reply, i really appreciate it. I do want them crispy so I’m going to prep everything else and just start a little earlier in the morning to cut the potatoes make them properly.

Hi Paul, you can store peeled potatoes overnight in completely submerged in water but when they are diced, they lose their structural integrity and don’t get as crispy.

Great to hear, Peter!
