How To Tell If Potatoes Are Done

We all know that potatoes are one of the most versatile and beloved ingredients in our kitchens, don’t we?

From baked and roasted to fried and mashed, they can take on so many delicious forms. But there’s one question that’s been bugging me – and probably you too – how to tell if potatoes are done?

Fear not, my friends, because today we’re going to explore some tried-and-true methods for checking the doneness of potatoes.

3 Best ways to tell if potatoes are done


To determine if potatoes are done, perform the poke test using a fork or skewer, checking for easy insertion with minimal resistance. Observe visual cues like golden-brown color and splitting skin, and taste a small piece to ensure a tender and creamy texture.

The Poke Test

The poke test is a super easy, quick, and effective way to check the doneness of potatoes, whether they’re boiled, baked, or roasted. All you need is a fork or a skewer, and you’re good to go. So, how do we do the poke test?

  1. Choose a fork, a knife, or a skewer. I usually use a fork, but you can use whatever you have handy.
  2. Use a heat-resistant glove or a towel to handle hot pans or trays. Make sure you’re careful not to burn yourself when checking your potatoes.
  3. Gently insert your chosen utensil into the center of the potato. The goal here is to feel the resistance (or lack thereof) as you pierce through the flesh.
  4. If your utensil slides in smoothly without much resistance, your potato is done! If you feel some resistance or the potato is still hard, give it some more cooking time and check again later.

Now, while the poke test is a fantastic method for checking the doneness of potatoes, it may not be the best option for every potato dish.

For instance, it works wonders for baked, roasted, or boiled potatoes, but might not be the most suitable for checking the doneness of mashed potatoes or a gratin.

In those cases, we need to use some other techniques to ensure our potatoes are cooked to perfection.

Visual Cues

We eat with our eyes first, and that’s not just an old saying – it’s true! Visual cues are essential in determining the doneness of our potatoes.

For example, when it comes to baked or roasted potatoes, we want to see that beautiful golden-brown color on the outside.

And if you’re boiling potatoes, you’ll know they’re done when the skin starts to crack or split. Remember, each cooking method comes with its visual cues, so keep an eye out for those telltale signs of doneness.

Visual cues are also great for how to tell if potatoes are bad as well. Find out how to store potatoes so that they don’t go bad.


As much as I love the poke test and using visual cues, nothing beats the good ol’ taste test. I always taste a small piece of potato before declaring it done, especially when I’m making mashed potatoes or a gratin.

The taste test not only helps me determine the doneness but also lets me adjust the seasoning if needed. So, don’t be shy – taste your potatoes and let your taste buds be the judge.

Not sure if your potato is properly reheated? Just as it’s crucial as knowing how to tell if potatoes are done, understanding the right way to reheat a baked potato ensures you get that perfect warm bite every time.
