Can You Freeze Roasted Potatoes?

Roast potatoes are a great side dish to any main meal, and they are versatile enough that you can add nearly any type of seasoning you can think of, and they’ll turn out great.

The one downside to making roasted potatoes is that the size of the potatoes in any one bag can vary greatly, making it difficult to portion it properly. 

You can easily end up with far more roast potatoes than is humanly possible to eat in one sitting, and you’ll probably only recognize this when it comes to dishing it up. Oops.

Luckily, all of your hard work doesn’t need to go to waste (literally). You can freeze roast potatoes, and it’s a very easy process that won’t take you long to do.

It is important to mention, though, if you freeze potatoes incorrectly, they will be ruined. That lovely crisp texture on the outside will turn grainy, and the inside will get soggy.

But if you freeze roast potatoes correctly, there’s no reason why they shouldn’t keep their delicious flavor and most of their texture, even when you defrost them.

But how long do roast potatoes actually last?

The Shelf Life Of Roast Potatoes

Roast potatoes will keep anywhere from 3 to 5 days, if you keep them in the fridge. The longer you leave them in there, the worse the texture will be when you come to use them again.

If you freeze roast potatoes, you can extend the shelf life up to a year. Perfect! This is provided that your freezer keeps them at a 0°F for nearly all the time.

Once you thaw roast potatoes (see also can you freeze gravy?), their shelf life will revert to 3 or 4 days when you keep them in the fridge. To preserve their texture and flavor, you should use them as soon as possible once you thaw them.

How Do You Freeze Roast Potatoes?

Preparing Roast Potatoes For The Freezer

If you’re making roast potatoes from scratch, hold off on adding any seasonings. 

It sounds mad, yes, and a little heart-breaking maybe, but you can save those for when you actually want to reheat and serve them. 

The seasoning itself may not actually freeze very well, so you’re better holding off until you take the roast potatoes out of the freezer.

Consider dicing the potatoes, as they’ll freeze and thaw more evenly, and you’ll save some defrosting time when it comes to actually using them.

You’ll want to wash, peel, and boil, and otherwise prepare the potatoes as you normally would.  

Let the potatoes cool completely before you attempt to freeze them. Once they are cool, transfer them into a shallow, airtight container. 

Make sure you don’t pack them too tightly, and leave a little room at the top. Seal, label, and freeze.

Freezing Leftover Roast Potatoes

If you have a lot of leftover roast potatoes that you know you won’t get through before they go off, you can freeze these too. 

Just keep in mind that any seasonings you have put on them may or may not freeze very well.

Portion them as necessary, if you feel that you won’t use the lot in one go. Grab some heavy-duty freezer bags, and divide the roast potatoes between them. 

Make sure to get rid of any air in the bags, seal, and label. Stick them into the freezer, and you’re done. 

How Do You Defrost And Reheat Roast Potatoes?

Only defrost the roast potatoes when you’re ready to reheat and use the leftovers, otherwise you might as well just keep them in the freezer.

If you made the roast potatoes with no seasoning, you don’t need to defrost them beforehand. 

Grab a suitable roasting dish, drizzle olive oil over the potatoes and add your favorite seasonings. 

They’ll need at least 15 minutes, maybe more, depending on the size of the potatoes.

If you’re dealing with leftover roast potatoes, you’re better off thawing them in the fridge, but not completely. 

Leave the potatoes for about two hours, no longer. Then put them straight into the microwave, and cook in 2 minute bursts to reheat them. 

To stop the potatoes from drying out, you can cover them with a damp paper towel. 


Roast potatoes are easy to get wrong when it comes to portioning, but you can freeze them to enjoy them at a later date with no problems.

This will also save you time and money, as in most cases, you won’t need to reheat them for long.
