The average serving size (in a restaurant) is 8oz of starch on the plate. So I would guess you're not meaning roasted whole, but cut into rondelles, seasoned and then roasted [I'm also assuming your potatoes will be about 1lb (or 16oz) a piece]. I would say around 75 potatoes.
NOTE: if you have a lot of other side dishes i would suggest cutting that number as not everyone may want those potatoes. keep the other side dishes to weight in accordance to the principle of 8oz starch 6oz vegetables 4-8oz meat' portioned accordingly. Hope that helped
I would use 40 pounds.
To make cheesy potato casserole most recipes require about 2 pounds of potatoes to feed 8 people. If you are feeding 150 people the recipe would need to be made 19 times over and require 38 pounds of potatoes.
I would make 38-40 pounds
I would use 40 pounds and cook them cut in halves in 2-3 large pots
3000 divided by 150 is 20 people.
That is 37.5 pounds.
About 5 pounds of mashed poatoes are needed for twenty people. ~in my opinion, five pounds of potatoes could feed ME!!!!!!!!........ but i LOve potatoes
an average potato may weigh 150 grams (0.33 lb) so there could be 20/25 in an 8 lb bag
It is 150 lbs
To feed 200 people with parsley potatoes, you generally estimate about 1/2 to 3/4 pound of potatoes per person, depending on whether it's a side dish or a main component. Therefore, you would need approximately 100 to 150 pounds of potatoes. Adjust the quantity based on the overall menu and portion sizes. Don't forget to account for the weight of any additional ingredients like parsley and seasoning.
There are approximately 68 kilograms in 150 pounds.
If it is a pre- entree salad, then about 36 pounds will do it. - If it is the main course, at least 80 pounds
