Do Potatoes Go Hard If Overcooked? (All Types)

Potatoes are a family favorite, whether baked, mashed, scalloped, or fried. There’s nothing worse than serving poorly cooked potatoes, hard and crunchy in the wrong places. Do potatoes go hard if overcooked? 

Potatoes can go hard if you bake, fry, or roast them for too long. However, hard potatoes usually result from undercooking if you’re boiling, baking, or cooking potatoes in a stew. The fastest way to soften potatoes is by frying or microwaving. Baking and roasting potatoes can take over an hour.

Cooking potatoes isn’t tricky, but you can run into problems where they turn out too hard or too soft. Let’s look at what happens if you overcook and undercook potatoes and how to rescue poorly cooked potatoes.

What Happens When You Overcook Potatoes?

Depending on your cooking method, overcooking potatoes or cooking them too long will have different results. For example, overcooking boiled potatoes go soft but overcooked baked potatoes go hard.

Overcooked Boiled Potatoes

If you are boiling potatoes to eat whole or for mash, overcooking will result in soggy, mushy potatoes. The longer you boil potatoes, the more water they absorb and the more starch they release.

Overcooked boiled potatoes will just start to disintegrate so there is not much fixing them. The best thing you can do is mash them up and have mashed potato instead.

Overcooked Baked Potatoes

Leaving baked or roast potatoes in the oven can be a disaster. Overcooking baked potatoes results in dry, hard potatoes that are not worth eating. The skins will start to blacken and will be like leather. You’ll have to throw them out and start again.

Overcooked Fried Potatoes

Overcooking fried potatoes is the easiest way to overcook potatoes, whether using a skillet, deep-fat fryer, or air-fryer.

Overcooked fried potatoes will burn, dry out, and go hard, making them inedible. Discard your fries and start peeling.

Overcooked Potatoes In The Microwave

Leaving your potatoes in the microwave for too long can either make the potato explode or leave you with burnt, hard potatoes. 

How To Avoid Overcooking Potatoes

Being vigilant in the kitchen will help you to avoid overcooking your potatoes. Here are some guidelines:

  • Check on your potatoes often.
  • Set a timer so to remind you when they’re ready.
  • Use a thin skewer or knife tip to test for doneness – the knife will go in quickly if the potato is cooked.

Why Are My Potatoes Still Hard After Cooking?

It’s disappointing to sit down to eat your potatoes, only to find that they are hard. There are two main causes of hard potatoes: the potatoes are either undercooked or overcooked.

Why Undercooked Potatoes Can Be Hard

Undercooking potatoes can leave them hard for a couple of reasons.

  • You haven’t cooked the potatoes for long enough – check the cooking times for the cooking method you’re using. Large potatoes will take up to an hour to soften.
  • If you boil potatoes too vigorously, the outside will cook more quickly than the inside, leaving you with a tender exterior and a hard center.
  • Your pot was too small, so the potatoes cooked inconsistently, leaving some potatoes raw and some cooked.
  • The chopped or sliced potato pieces were of different sizes, so they cooked unevenly.
  • If your potatoes are in an acidic dish (e.g., tomatoes or wine), they will remain hard because the acid prevents the potatoes’ cell walls from breaking down and releasing the softening starch. You will have to precook potatoes for acidic dishes.
  • Potatoes will also remain undercooked if you cook them at too low a temperature. The potato’s interior needs to reach boiling point, which is 212⁰F (100⁰C), for the cell walls to burst and release the starch. Low temperatures are often why potatoes and carrots don’t soften in a slow cooker or crockpot.

Why Overcooked Potatoes Can Be Hard

Baked, microwaved, roasted, and fried potatoes will harden as they overcook as the interior starts to dry out. As the potato dries out, it hardens and is not edible.

Other types of potatoes will soften as they overcook because they are moist when cooking, for example, boiled potatoes.

How To Soften Hard Potatoes

Hard potatoes can ruin a dish. Unfortunately, you can’t soften potatoes that are overcooked.

However, there are some quick fixes to soften undercooked potatoes and rescue dinner. 

  • If your boiled or baked potatoes are still hard, try cooking them longer before testing again. 
  • If you want your baked potato in a hurry, prick them with a fork and microwave the potatoes for four to eight minutes.
  • If your potatoes are in an acidic stew or soup, remove them carefully, rinse them, and cook them until soft by boiling or in the microwave.
  • If you’re mashing or ricing potatoes and find uncooked lumps, return them to the pan and add some milk. Cook gently, mashing and stirring until the potatoes soften.

How Long Does It Take To Soften A Potato?

How long it will take to soften a potato depends on your cooking method, the kind of potato, and the size of the potato.

How Long Does It Take To Boil Potato?

The ideal potatoes for boiling contain a high level of moisture and a low level of starch. Their texture is waxy rather than fluffy, and they are suitable for salads, soups, or stews. All baby, new, or early potatoes are excellent for boiling as they haven’t had time to develop much starch.

  • Thinly sliced or diced potatoes will soften in five to seven minutes.
  • Small or baby potatoes will take 10 to 15 minutes to soften.
  • Medium-sized potatoes will take 20 to 25 minutes to soften.
  • Large potatoes can take 45 minutes if you boil them whole.

How Long Does It Take To Bake Potato?

Baking potatoes are low in moisture and high in starch, with a floury texture that becomes fluffy when baked, fried, or mashed. When boiled or cooked in a stew, these potatoes will lose their shape, crumbling away.

  • Halved or quartered potatoes will take 30 to 40 minutes to soften when baked.
  • Large potatoes will take 45 to 60 minutes if you bake them whole. Remember to pierce them several times to avoid exploding while baking.

How Long Does It Take To Microwave Potato?

Microwaving is another quick method of softening potatoes but doesn’t produce the tastiest results or the best texture.

It will take about 10 minutes to microwave chopped potato pieces (for mashing) or a whole “baked” potato. Try flipping the potato halfway through for even cooking.

How Long Does It Take To Steam Potato?

It will take longer for a potato to steam than to boil. New potatoes are delicious steamed and drizzled in melted butter and herbs.

  • Thinly sliced potatoes will soften in 10 to 15 minutes if in a single layer in the steamer.
  • Small or baby potatoes will take 15 to 20 minutes to soften.
  • Medium-sized potatoes will take 30 to 35 minutes to soften.
  • Large potatoes will take 35 to 45 minutes if you steam them whole.

How Long Does It Take To Roast Potato?

Roasting is different from baking in that the potatoes are cooking in some kind of fat, whether olive oil or the drippings from a roast chicken or cut of beef.

  • Halved or quartered potatoes will take up to an hour to soften.
  • Large potatoes will take an hour to an hour and a half if you roast them whole. 
  • To avoid these long cooking times, chop and parboil your potatoes briefly before roasting.

How Long Does It Take To Fry Potato?

Whether in a deep-fat fryer or air-fryer, frying potatoes is a quick way to soften potatoes.

  • Fries will cook within five to six minutes in a deep-fat fryer, even if you double-fry them.
  • Your potatoes will cook within 10 minutes in an air-fryer.

How Long Does It Take To Slow-cook A Potato?

It can take hours to get potatoes to soften in a crockpot or slow-cooker, especially if they are part of a soup, stew, or casserole. 

  • Setting the slow cooker on high for a couple of hours will cook potatoes within four to five hours. Use the automatic setting to lower the temperature to simmer after this period.
  • If the crockpot is on low, schedule seven to eight hours of cooking time for soft potatoes.

How Long Does It Take To Pressure-Cook Potato?

An Instapot or pressure cooker is a helpful appliance if you want to soften potatoes quickly.

  • Thinly sliced potatoes will cook within five minutes.
  • Small and medium-sized potatoes will cook in 10 minutes.
  • Large, whole potatoes will take 15 minutes.


Hopefully, now you know that potatoes will go hard if overcooked. Although hard potatoes are usually the result of undercooking rather than overcooking. You can rescue undercooked potatoes by further cooking, but discard overcooked fried, roast, or baked potatoes and start again.
