5 Ways to Reheat Roast Potatoes (Best Tips)

Potatoes are an AWESOME side dish, but do they taste just as good the next day? Here’s how to reheat roast potatoes for the best taste!

So you made a bunch of potatoes for a side dish and now you have a ton left over. I love when that happens because leftovers are AMAZING!

But sometimes, eating them the next day can be tricky. A freshly-made dinner is hot and crisp (Depending on the dish); but trying to heat it up the next day just doesn’t give you the same great results.

I feel the same way with vegetables, like potatoes. You want them to be crispy on the outside when you eat them again, but that can be hard to reproduce. I cannot stand soggy potatoes!

There are a few different methods here! In this post, I’m going over 5 ways to reheat roast potatoes and giving my opinion on the best way to do so!

The best method of reheating roasted potatoes

There are a few different reheating methods. But my personal favorite is the air fryer, because the reheating process is faster and much easier. I share more below on how exactly to reheat them and why the air fryer is the best option!

How to Store

First of all, storing your leftover roast potatoes is a critical step. You don’t want them to go bad before you get a chance to eat them!

I store most of my foods in an airtight container, like Rubbermaid. They’ll usually stay fresh in the fridge for 3-5 days, which is plenty of time for us to eat them all. Make sure your leftover potatoes are room temperature before storing, to prevent excess moisture from getting into it.

Preheat your air fryer to 350 degrees F. Spray your potatoes with cooking spray and put them in the air fryer basket. Cook for about 10 minutes, pulling out the basket every 2 minutes to shake and distribute the cooking evenly.

My opinion

The air fryer is honestly perfect for this! Especially if you always keep this out on your kitchen counter. It doesn’t heat up your kitchen and reheats foods very quickly. Out of all the different ways to reheat food, this is my personal favorite.


How to reheat roasted potatoes in the oven

Preheat the oven to 400 degrees. Lay the potatoes on a baking tray (With aluminum foil on the bottom if you’d like), and spray with cooking spray.

Reheat in the preheated oven for about 10-15 minutes, flipping the potatoes halfway through.

My opinion

The oven is a really good way to make the potatoes crispy again! The only downside is that the oven takes awhile to heat up; and it will definitely heat up the house, which is no good in the Summer.

Toaster oven

The toaster oven is pretty much similar to a regular oven. Preheat to 400 degrees and lay the potatoes on a baking sheet that’s small enough to fit inside. Spray with cooking spray, and bake for 10 minutes, flipping the potatoes halfway through.

My opinion

As a small kitchen appliance, the toaster oven is pretty decent. But it might take a little longer to reheat these potatoes, so I’d rather use the oven instead for better results.

Pour a little bit of olive oil or butter in a large frying pan. Add the potatoes and cook on medium-high heat for about 10 minutes. stirring or flipping occasionally.

My opinion

This method may take a little longer, and the cooked potatoes may not get as crispy as they would in the oven. But I think it’s still a great option.

A microwave on a countertop

The cook time for this is the fastest, but not necessarily the best way.

Place the potatoes on a microwave-safe plate and heat in 30-second intervals until they’re heated through.

My opinion

This is my least favorite way to reheat potatoes. The outsides don’t crisp up like they would in the oven or air fryer; in fact, they may end up having soggy skin. If a microwave is all you have, that’s fine. The quality just won’t be as good as it was when you first cooked them.

Can you freeze roasted potatoes?

Yes, you can freeze roasted potatoes. Place them on a baking sheet lined with parchment paper, making sure they’re in a single layer and not touching. Put that in the freezer; and after a few hours, put the frozen potatoes in a gallon-size freezer bag and take out what you need when you’re ready to eat.

Roasted potatoes will usually stay fresh in the freezer up to 3 months. They’re still safe to eat after that. But the longer they sit in the freezer, the better chance they have of getting freezer burn.

I recommend defrosting them a little, then reheat using either the air fryer or oven for best results. They may not be as crispy as before due to excess moisture, but the oven/air fryer really help.

The defrosting process is easy, too. You can put them in the fridge overnight in an airtight container, or set them out on the counter for 15-20 minutes. It’s just enough time to thaw it enough to reheat.

How to use up leftover potatoes

Now that you’ve reheated them, how do you use up these amazing spuds? Here are some ideas:

  • Scramble them with eggs for a filling and hearty breakfast scramble
  • Add to salads or grain bowls
  • Top them with baked potato toppings
  • Dip them in your favorite sauces as a side item

Final Thoughts

In case you missed it, the air fryer is, in my opinion, the best thing for reheating foods. The other options are easy ways as well; but if you have an air fryer, definitely put it to use more often. It only takes a little time, but in the end you get really crispy potatoes.
