Reheating Roast Potatoes – Ultimate Guide

How to Reheat Roast Potatoes

Roast potatoes are quite a tedious process to make. From the peeling to chopping to spicing and roasting, it is a lengthy process. It takes a lot of prep work, but the results are pretty delectable.

Here are a few effective ways to reheat your leftover batch of roast potatoes.

In the Oven

The best way to reheat your roast potatoes is to throw them back where they came out. Yes, you go it right; I am talking about the oven. It is likely the best way to reheat your leftover roast potatoes. It does take a little more time than the other methods, but the results are worth the wait. Reheating a smoked turkey the next day after your Thanksgiving dinner is always worth it.

Steps to follow:

  • Start by preheating the oven to 400 degrees Fahrenheit.
  • On a baking tray, lay out an aluminum foil or a silicone mat and spread out the leftover roast potatoes. Sprinkle a bit of olive oil or melted butter on the potatoes to crispen up the edges further and spread them out on the tray evenly.
  • Once done, cover the tray with a single aluminum sheet to seal in the moisture from all edges. It spreads the heat evenly as well.
  • Set the timer between 10-15 minutes, depending on the quantity of potatoes you have.
  • Halfway through the re-roasting process, remove the foil and leave it in for the rest of the time.
  • Once done, take it out of the oven and enjoy the crispy and roasted goodness.

In the Microwave

Another way to reheat your leftover batch of roast potatoes is in the microwave. It is easy and takes under 5 minutes. But, this method is not the most favorable one if you enjoy eating crispy roast potatoes.Using a convection microwave is an ideal option.

Steps to follow:

  • Start by transferring the roast potatoes to a microwave-safe bowl or plate.
  • Cover the container’s top with a damp paper towel to prevent the potatoes from becoming too dry on the inside.
  • Manage the heat on the low to the medium side instead of using the microwave’s high heat settings.
  • Microwave the potatoes for 2-3 minutes to start with, and then you can check if it needs more crisping up on the edges.

In the Skillet

If you don’t own an oven or a microwave, the next best option for you is the skillet. But, it requires you to be extremely vigilant because the moment you move away for a minute, you are risking your potatoes burning entirely on one side. Managing the heat while reheating on a skillet is extremely important.

Steps to follow:

  • Start by pressing the roast potatoes with the back of your palm to flatten them out for easier reheating and crisping.
  • Once done, set it aside and put the skillet in the gas oven and let it heat on a low flame for 1-2 minutes.
  • Brush some oil or butter on the bottom of the skillet to prevent the potatoes from sticking to the bottom.
  • Lay out the leftover roast potato on the skillet and cover it with a lid, keeping the gas stove’s flame on low.
  • Keep flipping the potatoes every 1-2 minutes to prevent them from burning. Make sure that you flip them even more frequently once the potatoes are almost done.

In the Toaster Oven

A toaster oven mimics an oven’s results and is the best alternative to using an actual oven. The only downside to using a toaster oven is the limited space. So, if you have many roast potatoes leftover from your Sunday roast, you will have to reheat them in batches.

Steps to follow:

  • Preheat the toaster oven to 400-degrees Fahrenheit.
  • On a smaller baking tray, grease the tray’s bottom with some butter or olive oil to prevent the potatoes from sticking to the tray. Line the leftover roast potatoes on the tray in a single layer.
  • Set the timer for 15 minutes and then put the baking tray inside the toaster oven.
  • Halfway through the reheating process, flip the potatoes to crisp them up from every side.
  • Once done, take them out of the oven and enjoy them warm and crisp.

In the Air Fryer

For the health nuts out there who don’t enjoy oil or grease in their cooking, an air fryer is a good alternative. It is becoming popular because of the nutritional quotient it adds to the food. And, moreover, it makes the reheating process extremely simple and less time-consuming.

Steps to follow:

  • Line your air fryer rack with a greaseproof baking sheet and fill it with your roast potatoes.
  • Start the reheating process at 350-400 degrees Fahrenheit for 5 minutes, depending on how much potatoes you have going. You can check the potatoes after 5 minutes and reheat them for a minute more if you want them to be crispier.

How to Reheat Frozen Roast Potatoes?

How to Reheat Frozen Roast Potatoes

If you are someone like me who enjoys roast potatoes but hates cooking, you will have a batch of frozen leftovers in your freezer. And, that’s completely fine too. Freezing your leftover roast potatoes is completely healthy and doesn’t meddle with the taste.

As for the reheating process, there are a few things you need to follow. Unlike other frozen foods that require defrosting, I wouldn’t suggest the same with the frozen roast potatoes. It can leave them soggy, even after the reheating process, so it’s better that you take them out of your freezer and reheat them directly.

Steps to follow:

  • Start by lining a baking sheet with a silicone mat or spray some oil on the tray directly. Spread out the leftover roast potatoes on the tray and spray some more oil on the top.
  • Cover the baking tray with aluminum foil to ensure even reheating.
  • Put the tray into an already preheated oven at 400 degrees Fahrenheit.
  • Reheat them for 15-20 minutes till they crisp up on the edges. You can flip them halfway through the reheating process to prevent them from burning on the sides.
  • Once done, take them out of the oven and enjoy them piping hot.


Reheating roasted potatoes is not as tough as it seems. You need to know the right ways to do them. Depending on what kind of equipment you have in hand, use it to your benefit. Additionally, if I could do it after a few failed attempts, I am pretty sure you can master it the first time around.
