How many potatoes for mashed potatoes for 5?

When preparing mashed potatoes, every individual for whom you are cooking will require almost a half-pound (228 grams) of potatoes so that everyone will get a serving that equals one cup.

However, the number of potatoes you will require will vary with the size of potato you are using and the quantity each person will consume. By and large, you can expect to use about 1 medium-large potato per individual, which will make almost 1 cup of mashed potatoes for every diner.

A single cup of mashed potatoes is equivalent to 0.5 pounds of potatoes, considering that 5 cups of mashed potatoes would be equal to 2.5 pounds of potatoes. To prepare 5 cups of mashed potatoes for 5 persons, you would require 5 medium-large potatoes or 20-25 baby potatoes.

The number of potatoes varies with 


One important thing which affects the number of potatoes is the size of potatoes you use when you are working with your measurements. If you are taking medium-large potatoes, then 1 potato per individual will be enough. 

If the potatoes are medium in size, you will require 1 or 2 potatoes for each individual you are providing. If the potatoes are more undersized, then 4 to 5 potatoes are nearer to 0.5 pounds.

If you like to be extremely precise with your measurements, you can always use a weighing scale to measure the potatoes. This way, you can be certain that the potatoes you are using per individual weigh 0.5 pounds.


Another thing that will make a difference when you are measuring out potatoes is the appetites of those you are providing. If you know that you are making mashed potatoes for a gathering that likes them and desires a second and third cup, it is probably not the right moment to make a limited amount of something. 

In that circumstance, you will have to toss a few more potatoes in the container so that there is enough to satisfy the guests.

If you are serving fewer appetites or people that are monitoring their carbohydrate consumption, you might have to reduce the number of potatoes you add. The idea is always to predict the requirements of those you are providing so you do not have to discard food or cook very little.

Though the serving size for mashed potatoes is one cup, if you are serving it as a side dish, you can split this quantity in half, it is based on how starved the guests are.

You can also cook an extra amount and use leftovers the next day. It is always more suitable to make extra than to not have sufficient.
