How to Cook Cubed Potatoes in a Microwave


First up, size. This is one of the most important factors.

The length of time to microwave a potato mostly depends on how big it is. This is because the heat and microwaves will need to penetrate the potato to heat and cook it. 

The bigger the potato, the longer it will need to be in the microwave. 

The average-sized potato is around 4-5 inches long. This size potato will take around 15-20 minutes to cook through. It will likely take longer but it’s best to start out with 15 minutes.

Then, if more time is needed, return the potato to the microwave for an additional 10 minutes. Repeat, or reduce the time to 5 minutes, as needed.

How to reheat frozen roast potatoes in microwave

When reheating frozen roast potatoes, it is important to defrost first to avoid the potatoes from becoming soggy. This is different than oven method where you can directly reheat from the freezer to the oven. 

In order to reheat frozen roast potatoes in microwave, transfer the serving amount to a microwave-safe dish. Cover the dish with a paper towel loosely so the steam can escape and the towel can absorb any excess moisture.

Microwave on 50% power or defrost setting for about 5 minutes. Flip every minute to thaw the frozen roast potatoes evenly.

Once the roast potatoes are completely brought back to room temperature, immediately transfer to a preheated microwave crisper pan to reheat in the appliance to crisp up the edges.

How Long to Microwave Baked Potatoes

We find that this 10-minute method works well to create a perfectly tender baked potato – 5 minutes on one side, 5 minutes on the other. However, not all microwaves cook at exactly the same power. If you’ve found in the past that your microwave is more or less powerful than other microwaves, you may want to adjust the recipe by a few minutes.

3. Use a knife to pierce the potato and check for doneness. The potato should feel tender (but not mushy) all the way through.

4. If the potato is finished, allow it to sit for 1 minute to cool slightly before removing it from the microwave. If still hard, continue to cook in 1-minute increments until the potato is tender.

Getting Crispy Skin on a Microwave Baked Potato

If you really love a baked potato with crispy skin, you can still get that even if you do most of the cooking in the microwave.

To crisp the skin of a microwave baked potato: Preheat your oven to 425°F and cook the potato(es) in the microwave according to the recipe instructions. Once cooked, rub your potato with olive oil—it will be hot, so handle with care! Sprinkle generously with salt (preferably coarse salt) and place the potato on a baking sheet.

Bake until the skin is crispy, usually 10 to 15 minutes. Serve and enjoy!

Baked Potato Toppings

Once your potatoes are finished, time to load them up. You can use classic baked potato toppings like:

  • Butter

How to Safely Clean a Microwave

Okay we’ve all been there, you’re way past ‘hangry’ and you need to get food on the table now or else you might just eat last night’s potato chowder leftovers cold from the fridge. You put your bowl in the microwave, do some button mashing, and impatiently pace as the timer counts down much too slowly and it doesn’t even occur to you that you forgot to put a lid on it until you hear a faint sizzling sound, open the door, and —chowder everywhere.

Don’t despair. Eat your chowder. Then, grab some things you probably already have around your house to easily clean up the spill. Here’s what you’ll need:

  • 1 cup of water
  • Lemon, lime, or orange slices
  • A few tablespoons of white or apple cider vinegar

Combine everything in a microwave-safe container (a glass or ceramic bowl will work), and turn the power on high for a few minutes until the window is nice and steamy, then let it sit for five minutes to cool down. Open the door, wipe it all down with a sponge, and there you have it. No more chowder splatter paint.

Enhancing The Cooking Experience

There are several little things you can do to further enhance the cooking experience.

  • You can confirm that the potato is properly cooked by sticking a fork into the center of it. The center needs to be soft, yet firm.
  • Resting the potato in the microwave for a few minutes will ensure the right level of fluffiness inside. You could also remove from the microwave and wrap in aluminum foil for best results. The foil will also keep the potato nice and warm for a considerable period of time, in case your guests are delayed.
