4 Best Reheating Methods for Roasted Potatoes

#1. How To Reheat Roasted Potatoes In An Oven?
Using an oven to reheat roast potatoes is the best way to reheat roast potatoes.
For every food from seafood to Italian sausage, reheating baked potato in oven provides them a tasty flavor and a yummy appearance. Since you roasted potatoes in the oven before, it would be better for the potatoes to be reheated in the same place.
However, bear in mind that the reheating process will not be the same as the cooking one, so you should follow these guidelines strictly if you don’t want your potatoes to turn mushy and inedible.
Step 1: Preheat your oven
It would help if you reheated your oven to 300-400 degrees F before starting to handle your potatoes. Don’t forget this step; otherwise, you will waste a long time waiting after.
Step 2: Prepare your potatoes.
Take your roasted potatoes out of the fridge and place them one by one on the cooking tray. If you don’t want the potatoes to stick to the tray, cover the tray with a light foil on the upper side. Please make sure the potatoes are separated; otherwise, they can be messy when thawed and reheated.
Step 3: Reheat your roast potatoes.
By the time your oven is ready, cover the potatoes with foil. The foil will make the potatoes retain the heat more effectively, producing more evenly cooked roast potatoes a few minutes later. Cook the potatoes for 15 – 20 minutes, depending on how many potatoes you are putting in.
Step 4: Serve your roast potatoes.
After 20 minutes, take your potatoes out and leave them at rest for 5 minutes. Then you can start plating them on dishes and enjoy a warm, handy, and delicious reheated roast potato with your family.
#2. How To Reheat Roast Potatoes In An Oven Toaster?
Compared to using the oven, reheating roast potatoes in an oven toaster takes more time than usual. However, by paying more time and effort, you will get back more perfect roast potatoes, with shiny, crispy layers on the outside and fluffy, rich-in-content potatoes on the inside.
Here are the steps of reheating roast potatoes in an oven toaster:
- Step 1: Set your toaster oven’s temperature to 350 degrees F.
- Step 2: Prepare your potatoes on a baking sheet (make sure to lay on an extra foil to make the potatoes don’t stick to the sheet)
- Step 3: For every side of your potatoes, heat them in the oven for 20 minutes. Once the first attempt is done, flip the potatoes to the other side so that all potatoes can be reheated evenly with nice color and great taste.
- Step 4: Once you see the potatoes are hot and evenly cooked with yellow on the inside and brown on the outside, you can turn off the oven, leave your potatoes rest a bit before serving them.
#3. How To Reheat Roast Potatoes In An Air Fryer?
Another attempt to reheat roast potatoes can rely on an air fryer. Of course, you fry your roast potatoes in the traditional ways using pans, but air frying is a much quicker and more effective technique in reheating roast potatoes.
Moreover, using an air fryer to heat roast potatoes is a healthy approach as this method only asks for a little oil, or even none, but still, you can get deep-fried roasted potatoes as the final result in a few minutes only! If an air fryer is available in your kitchen, then let’s follow the steps on how to reheat roast potatoes in an air fryer:
- Step 1: Set your fryer’s temperature to 400 degrees F.
- Step 2: Once the fryer is hot, put in your potatoes and keep an eye on them by handling them lightly with a spoon.
- Step 3: After 5-8 minutes, the potatoes should have been crispy. You can see the potatoes’ outcome by yourself and remove them from the fryer once they are ready.
#4. How To Reheat Roast Potatoes In A Microwave?
Can you reheat roast potatoes in a microwave?
Well, yes, but reheating roast potatoes in a microwave will not bring such crispy or delicious roast potatoes like you might have expected, but it will at least keep your potatoes hot and edible.
That’s why we put this method at the last position in the list, as it is not the best way to reheat potatoes. However, you can still enjoy a fine meal if using this technique. Here’s how reheating potatoes in the microwave goes:
- Step 1: Place your potatoes in a dish or a bowl and set your microwave’s heat to low or medium (if the microwave is too hot, it can harden the potatoes)
- Step 2: Place a plastic wrap or a damped tissue on the potatoes to have some moisture. In this way, the potatoes won’t dry out while you reheat the baked potato in the microwave.
- Step 3: Microwave the potatoes for 1-2 minutes, depending on how many potatoes you have. Keep a close eye on them and remove them from the microwave instantly if you see they are done reheating, and that’s how to reheat potatoes in microwave.
