I love mashed potatoes. There’s something about the creamy, fluffy texture that just makes me happy. And they’re so versatile—you can top them with anything from gravy to shredded cheese to bacon bits.

But sometimes I don’t have the time or energy to make them the traditional way. That’s where these easy microwave mashed potatoes come in. You can have a delicious, satisfying side dish in just minutes!

Plus, they’re perfect for when you’re short on time or ingredients. All you need is some potatoes, milk, butter, salt, and pepper. And there are lots of variations you can try, too. So why not give them a try? They’re sure to become a new favorite!

Ingredients Overview


Yukon Gold potatoes have long been considered the best type of potato for making mashed potatoes. This is because they have a rich texture and subtle flavor that other potatoes just can’t match.

But any type of potato will work for this recipe. So if you have russet, red, or white potatoes on hand, feel free to use them.


When it comes to making creamy mashed potatoes, whole milk is my go-to ingredient. Not only does it add a lovely richness to the dish, but it also helps to thin out the potatoes so that they’re not too dense. However, if you want a lighter mashed potato, you can use a light cream.

Unsalted butter

Many home cooks prefer to use unsalted butter when making mashed potatoes. The main reason for this is that it decreases the chances of the potatoes becoming too salty.

When using salted butter, it can be difficult to gauge how much salt is already in the butter, and this can easily lead to mashed potatoes that are too salty. By using unsalted butter, you can control the amount of salt in the dish more easily, ensuring that your mashed potatoes are perfectly seasoned.

In addition, some people believe that unsalted butter is fresher than its salted counterpart. If you’re using fresh, flavorful potatoes, you want to be sure that the butter you’re using is of the same quality.

Kosher salt

I like to use Morton kosher salt to make microwave mashed potatoes. I find that the kosher salt doesn’t clump up like some of the other brands, and it adds just the right amount of saltiness to the dish.

Freshly ground black pepper

Freshly ground black pepper is always going to taste better than pre-ground pepper, no matter what you’re using it for and this is especially true for mashed potatoes. The essential oils in black pepper are what give it its distinct flavor, and these oils begin to dissipate as soon as the pepper is ground.

As a result, freshly ground pepper will always taste more intense than pepper that has been sitting on a grocery store shelf for months. In addition, freshly ground pepper is less likely to contain additives or preservatives that can diminish its flavor.


If you are looking to make a healthier version of mashed potatoes, try using light cream instead of milk and oils such as canola oil instead of butter. You can also add some flavor by using paprika instead of black pepper.


Everyone has a different way of making mashed potatoes, and that’s part of what makes them so special. Here are a few variations on the classic microwave mashed potatoes recipe that will make them even more delicious.

Adding roasted garlic gives the potatoes a mellow, sweet flavor that pairs well with most herbs and cheeses. Simply roast a head of garlic in the oven until it’s soft and fragrant, then squeeze the cloves out of the skins and add them to the potatoes.

If you want a bit more flavor, try adding fresh herbs. Chopped parsley, chives, or rosemary go well with roasted garlic, and add a nice herby note. Just stir them in at the end.

If you’re looking for a richer, creamier version of mashed potatoes, try adding some sour cream, crème fraîche, or Greek yogurt. It will give the potatoes a nice tangy flavor and make them extra-creamy.

Finally, if you’re feeling adventurous, try adding some grated cheese to your mashed potatoes. Hard, assertive cheese like cheddar, Parmesan, or Pecorino Romano will add a nice depth of flavor.
