Why is it so hard to reheat roast potatoes?

The very charm of roast potatoes is their texture.

Roast potatoes are crisp and caramelized on the top while being utterly creamy and fluffy on the inside.

What’s more, is that they can take on completely anything you season them with. However, reheating roast potatoes can be even more challenging than making them.

When we reheat them, roast potatoes can turn gummy and chewy, and lose their fluffiness and crispness. However, keep reading to learn the best way to reheat roast potatoes below.

Can I reheat my roast potatoes in any appliance?

Yes, you can! This comprehensive guide tells you how to reheat roast potatoes in a range of different appliances so that no one is ever left out.

Reheating roast potatoes in the oven

Ovens are the most common method of cooking roast potatoes, so it makes sense to reheat them in the oven as well. However, it can be much more time consuming as compared to say, an air fryer.

Additionally, be sure to follow the steps listed below correctly, or you might end up with mushy potatoes instead.

  1. Preheat your oven to 200 degrees Celsius/400 degrees Fahrenheit.
  2. Cover your baking tray with foil, and spread out your potatoes evenly.
  3. Make sure none of the pieces is overlapping.
  4. Cover the potatoes entirely with foil. This is the most critical step and helps you ensure crisp, evenly roasted potatoes.
  5. Cook for around 15 minutes and serve.

Reheating roast potatoes in an oven toaster

The toaster oven is pretty similar to a regular oven, so the directions for the two will overlap.

This process is also a bit time-consuming. However, it gives you roast potatoes that are perfectly crisp on the outside and light and fluffy inside.

  1. Preheat your toaster oven to  200 degrees Celsius/400 degrees Fahrenheit.
  2. Lay down your roast potato leftovers on a piece of foil on a baking sheet.
  3. Roast your potatoes for around 20 minutes, and keep turning the pieces after every 5 minutes to ensure you get even color.

This process is like re-roasting old potatoes, and it can give them the crunch that they need.

How to reheat roast potatoes in an air fryer

Air fryers are fast overtaking traditional methods of frying.

They are much faster, but the most significant selling point is the fact that they are much healthier. Air fryers use only a minimal amount of oil, or none at all, and can give you crisp food that looks like it’s been deep-fried!

If you have an air fryer in your kitchen, here’s how you can use it to reheat your potatoes.

This method is super-fast, and you can have your roast potatoes revived in minutes.

  1. Set your temperature around 150-200 degrees C 350-400 degrees F, depending on the air fryer you have.
  2. Reheat your potatoes for around 3-4 minutes, and afterwards, check on your potatoes.
  3. Cook the potatoes until they’re as crisp as you need them to be, and then serve!

Reheating roast potatoes in microwave

There’s a good reason why this is the last option we listed, and that’s because it’s the least favourable.

When reheating roast potatoes with a microwave, your potatoes can either turn out way too mushy or too hard. However, sometimes you have to make the most of what you have, so here’s how you can reheat roast potatoes in a microwave.

  1. Use your microwave only at low or medium power.
  2. Cover them with a damp paper towel, and ensure that no pieces are overlapping.
  3. Cook for short periods of time, and keep checking on your potatoes in the intervals.

Can I freeze and reheat frozen roast potatoes?

Whether you want to make potatoes ahead of time, or have ended up cooking more than you needed, there’s a way to save the situation.

For make-ahead roast potatoes, coat them in flour, some fat, and seasoning, and stick them in a Ziploc bag. When you have to cook them, simply cook as you would regular roast potatoes.

You can also freeze and then reheat leftover roast potatoes using any of the methods listed above. Just make sure you defrost them well before cooking.

Ever since I started cooking I’ve been fascinated by how different people’s techniques are and how they best utilise the ingredients around them. Even the person living next door will have their own unique way of frying an egg or cooking a salmon fillet.

This fascination led me on a journey across the globe to discover the countless practices and traditions the world of cooking has to offer. I thought you’d enjoy and find value in sharing that journey with me so I created Cooked Best!
