How Many Potatoes Should You Make Per Person For Mashed Potatoes?

It never fails: every time you make homemade mashed potatoes, you end up either making too much and having a ton of leftovers. Or you end up having to give each person a tiny portion because you underestimated how many potatoes you would need so that everyone could get their fair share.

Cooking experts all agree that when making mashed potatoes, each person you are cooking for will need about 1/2 pound of potatoes so that everyone will receive a serving that equals 1 cup.

But how many potatoes are in a 1/2 pound? There are a few variables when it comes to figuring out how much a potato weighs that we will discuss below. In addition, you must also think about who you are feeding and how much they will eat.

Size

The first thing you will have to consider is the size of potatoes you are using when you are doing your calculations. If you are using medium/large potatoes, then one potato per person will be sufficient. If the potatoes are medium-sized, you will need 1-2 potatoes for each person you are feeding. If you use smaller potatoes, then 4-5 potatoes are probably closer to a 1/2 pound.

If you want to be extremely accurate with your weights, you can always use a kitchen scale to weigh the potatoes. That way, you can make sure that the potato or potatoes you are using per person weigh 1/2 pound.

Appetites

Something else to consider when you're counting out spuds is the appetites of those you are feeding. If you know that you are making mashed potatoes for a group that loves them and asks for seconds and thirds, it's probably not a good time to skimp. In that case, you will likely want to err on the side of caution and throw a few extra potatoes in the pot so that there is plenty to go around.

If you are cooking for smaller appetites or a group that is watching their carb intake, you might be able to cut down on the number of potatoes you use. The secret is always to anticipate the needs of those you are feeding so you don't waste food or make too little.
