Ingredients and substitutions
- Potatoes - You can use any potatoes to make our microwave mashed potatoes, however starchy and fluffy potatoes work the best. King Edwards, Maris Piper, Russets, Yukon golds, Desirée or Rooster (which is what we used) work really well for making the perfect mashed potato.
- Milk - We used whole milk as it makes it all nice and creamy. However you could use skimmed or semi skimmed, or even swap it for a dairy free version.
- Butter - This adds lots of creaminess. You could use creme fraiche instead.
- Salt and pepper - Generously season.

Health benefits of potatoes
Whilst we do love a good sweet potato mash, you just can't beat mash made with white potatoes. White potatoes have so many nutrients in them, they really shouldn't get a bad reputation.
They are low in fat, sodium and cholesterol, they have nearly half of your daily vitamin C and they are a great source of potassium - even more than a banana. They are full of fibre and magnesium, and they are filling too. On top of this, they are also suitable for almost any diet, from vegan to gluten free. I am not sure what more you could want?
Why use a microwave
You will never get the same light and fluffy mashed potatoes using the microwave as you would on the hob. So, you might be wondering what the point of using the microwave is.
Microwaves have received a bad reputation over the years. They have been called lazy and they have been called dangerous. But, if you are looking at these recipes then I am guessing that you don't believe either of those, and neither do we. Let's dispel those myths.
Firstly, there is no real evidence that shows that microwaves are dangerous to your health. You will find a lot of information on the internet to say they are, but nothing scientifically proven. Studies have shown that using a microwave might be better at preserving nutrients than other cooking methods.
Microwaves are for lazy people? Nope! That is such an ableist thing to say. There are many reasons why people might use a microwave as a convenient method of cooking, such as not being able to stand at the cooker for any length of time.
Sometimes the microwave can be a bit of a life saver. If your oven breaks, or you are having your kitchen renovated, you need to be able to make meals with just a microwave. Maybe you are living in accommodation with no/limited cooking facilities like a hotel/studio/student halls. We want to show just what you can do with a microwave. We also love them for smaller portions.
We have a full section of microwave recipes for you to try.
The great thing about microwave mashed potatoes is that once it is cooked, there are lots of different ways that you can flavour it. We went with a little fresh parsley, but fresh chopped rosemary or thyme would work well.
Cheesy mashed potato just hits the spot for comfort food doesn't it?! Why not stir in some grated Parmesan or cheddar to make it nice and creamy? A spoonful of creme fraiche makes it really creamy too.
If you want to make some really indulgent microwave mashed potatoes, then stir some chopped cooked bacon into it. If you like a kick of heat in your food, then you can stir in some dried red chilli flakes.

Frequently Asked Questions
You can store any leftover mashed potatoes in an air tight container in the fridge and they will keep for up to 5 days. We wouldn't recommend freezing mashed potatoes. Once they are defrosted, they tend to go a bit gritty.
We use a really sturdy potato masher to mash our potatoes, as we are fine with a few smaller lumps. However, if you like your mashed potatoes super smooth, then get yourself a potato ricer. This gives you really smooth and creamy potatoes, and makes sure that they aren't overworked like they would be with a masher, which is key if you are going to use leftovers to make gnocchi.
Whilst leftovers of this side dish is rare in our house, if you do have any leftovers then there are a few really good options to make sure that nothing goes to waste. You can make leftover mashed potato cakes by mixing them with an egg and a little flour, then forming into patties and frying. Or, you can make our Leftover Mashed Potato Gnocchi.
This really depends on what potatoes you are using. If you are using the ones we have listed above, then your potatoes won't dry out. Also remember that the power of your microwave matters and you don't want them to dry out.
