How to make mashed potatoes in the microwave
Making potatoes in the microwave is really easy. I will share with you a few tricks to getting smoothy and fluffy microwave mashed potatoes that are evenly cooked.
- Peel the potatoes (if desired) and cut into 1-inch chunks.
- Place the potato chunks into a medium microwaveable bowl. Then add water to rinse off excess starch:
- Drain the water and cover the bowl with plastic wrap. poking a hole with a knife tip so steam can escape. Then microwave for 10-12 minutes on high power until fork-tender:
- Add the milk, butter, salt and pepper to the potatoes.
- Mash the potatoes until smooth and creamy.
Best potatoes for mashed potatoes
The best potatoes for mashed potatoes are baking potatoes such as russets and Yukon golds. They’re starchy potatoes with a floury texture that disintegrates easily for smooth mashing with no lumps!
Do you need to peel potatoes before microwaving?
You don’t need to peel potatoes when making microwave mashed potatoes. It’s a matter of personal preference for the final texture, and they’ll cook just as well with the peels on or off.
How long to microwave potatoes for mashing?
If the potatoes are cut into 1-inch chunks, they’ll take 10-12 minutes on full power in a 1200-Watt microwave (the strength of most built-in microwaves).
You’ll need 13-15 minutes on full power in a 600-800 Watt microwave, which is the strength of most countertop models.
If you cut the potatoes into larger chunks, you’ll also need extra time. Medium starch potatoes such as red potatoes can also require a few minutes more to become soft.
How to make mashed potatoes creamy and fluffy?
The best way to avoid lumps is to choose starchy potatoes and cook them thoroughly. If you still encounter lumps, then simply put the potatoes through a ricer (this is how restaurants mash potatoes). If you don’t have one, then microwave the mashed potatoes several more minutes to soften the lumps.
The mashing or ricing action, along with added liquid and butter, will make your mashed potatoes fluffy and creamy.
Is it safe to microwave potatoes?
Yes! There’s some risk of whole potatoes exploding in the microwave when steam can’t escape. When microwaving whole potatoes, always prick at least 3 holes an inch deep using a skewer or fork to avoid pressure buildup during cooking.
