Things You'll Need

Boiling potatoes in the microwave is an easy way to cook them quickly, whether you want to make mashed potatoes or use them as an ingredient in another recipe. This method requires very little time and preparation, and you can easily boil your potatoes in under ten minutes. To boil potatoes in the microwave, you’ll need a microwave-safe bowl, some plastic wrap, and a small knife to check the potatoes when they’re done cooking.

How Do You Boil Potatoes in the Microwave?

Poke the washed potatoes with a fork, then place them in a microwave-safe bowl. Cover the bowl with plastic wrap so steam doesn’t escape. Microwave baby or diced potatoes on high for 2 minutes. For bigger potatoes, microwave on high for 4 minutes.

Leaving the skin on will keep more of the nutrients inside of the potato, and add texture to the potato’s flavor. But if you’re planning on mashing the potato or using it as an ingredient, you’ll probably want to skin them first.^{[1]

Find a microwave-safe bowl that will fit all of your potatoes. Most ceramic bowls will work well in the microwave. Try to avoid any kind of plastic that might melt.^{[2]

Wash your potatoes by hand, making sure to cover each part of the potato with water. Do not pat them dry. The layer of moisture left on the potatoes will help them cook evenly.^{[4]

Poke each of the potatoes with a fork on all sides. Use a fork to poke several sets of holes around each of the potatoes.^{[5]

- The holes should go deep into the middle of the potato. Depending on the size of your potato, you may want to use a skewer to create deeper holes.

Put the potatoes in your bowl. They should still be a little wet from the wash that you gave them, but if they’re drying off at this point, give your potatoes a quick rinse. You can also add a teaspoon of water to the bottom of your bowl before turning the microwave on.^{[7]

- The water keeps your potatoes from drying out as they cook, but if they’re totally soaked the water won’t evaporate and you’ll be left with moist potatoes.

- Most plastic wraps are microwavable, but check the packaging before using it to cover your potatoes.
Turn your microwave’s power level to the highest setting available.^{[9]

Select your time based on the size of your potatoes. For smaller diced or baby potatoes, start with two minutes in the microwave. For bigger potatoes, like sweet or russet potatoes, start with four minutes in the microwave.^{[11]

- The wattage of your microwave will affect the cooking time required for potatoes. It’s always better to start lower though when it comes to cooking in the microwave. You can always add time, but you can’t undo shriveled and dry food!^{[12]

Keep an eye on your potatoes while they cook. Potatoes can explode in the microwave if the pressure inside them builds up to high levels. Stay in the kitchen while they microwave to keep an eye on them.^{[13]

- Microwaves heat up the inside of the potato first. This means that the pressure will build up inside of the potato as it cooks.^{[14]

- An explosion is more likely to occur if the skin is still on or you haven’t poked enough holes in your potato.^{[15]

- Watch out for any movement or popping noises in your microwave. That may be the pressure trying to fight its way out of the potato.

1
Use an oven mitt to take your potatoes out and check them. The potatoes will be extremely hot at this point, as will the bowl that they’ve been cooking in. Put on an oven mitt and carefully remove them from the microwave. Put them on the countertop and peel back the plastic wrap away from you.
- Open the plastic wrap away from your body and face. There will be a lot of hot steam coming out of the bowl and you don’t want to get burned.
2
Poke your potato with a paring knife to see if it’s done. Take a small paring knife and insert it into one of the potatoes. If there’s barely any resistance when you slide the knife in and out, then your potato is fully boiled. If there’s a little resistance and it’s hard to pull your knife out, microwave them for an additional minute and check again.^{[16]

- If you can’t insert your knife at all, the potatoes haven’t cooked at all. Check your microwave’s power level and try cooking them again.^{[17]

Allow your potatoes to stand for a few minutes to cool off. Because potatoes have a skin that seals in the heat, they’ll be extremely hot when you take them out of the microwave. Let them stand for 1-2 minutes before touching them or taking any additional steps.^{[18]

- Consider garnishing your potatoes with some herbs and spices while they rest. Parsley and a pinch of salt can go a long way to add flavor to this simple dish.^{[19]
