💡 Peel Tip: Skin-on roasting usually stretches the yield, while peeled cubes lose a little more weight. Match the style to the pan if you want the estimate to feel tighter.
💡 Hold Tip: For long buffet service, round up the pan count first. Then keep a little extra warm in reserve so refills stay smooth and the tray never looks skimpy.

To calculate the number of sweet potatoes you will need for a meal, you will need to ensure that there is enough food for all the peoples who will be eating and to ensure that there is no wastage of food. The number of sweet potatoes you will need per person will change based off the way in which you serve the sweet potatoes to you guests. If you serve the sweet potatoes as a side dish to meals that contain proteins like chicken or ham, a person will eat approximately three-quarters of a cup of cooked sweet potatoes.

If, however, you serve the sweet potatoes as the main source of carbohydrates for your vegetarian meal, a person will eat more sweet potatoes, consuming approximately one and a quarter cup of sweet potatoes. If you serve the sweet potatoes as a buffet-style meal, a person will eat approximately two-thirds of a cup of sweet potatoes, as people will use the sweet potatoes as part of many other meal. Finally, if you serve the sweet potatoes as part of a holiday meal, a person will eat a full cup of sweet potatoes, as many holiday meals includes large portions of food.

How Many Sweet Potatoes to Buy for a Meal

The number of children that will be eating will change the amount of sweet potatoes that you need to prepare. Because children tend to eat 35 percent less volume than adults, if you are preparing a meal that includes many children, you will require fewer sweet potatoes to prepare. For example, when calculating the amount of sweet potatoes that you need for a meal that will include 20 guests, but 15 percent of those guests are children, you can calculate the amount of sweet potatoes needed for 17 adults.

In this way, you can prepare enough sweet potatoes for all of the the guests who will attend the meal without having any left overs. The number of sweet potatoes that you will prepare will change based on the way that you prepare the sweet potatoes. If you prepare the sweet potatoes as a mashed and pureed side dish, approximately one pound of raw sweet potatoes will yield three cups of prepared sweet potatoes.

If you roast the sweet potatoes, approximately one pound of raw sweet potatoes will yield two and a half cups of roasted sweet potatoes. Casseroles fall somewhere in between. Additionally, sweet potatoes prepared with sweet toppings will be eaten more fast than savory sweet potatoes.

The length of time that the sweet potatoes will sit out on a buffet may alter the number of sweet potatoes that should be prepared. If the sweet potatoes will sit out for thirty minutes, the amount of sweet potatoes will not change significant. However, if they sit out for two hours, some of the sweet potatoes will evaporate.

Therefore, if the sweet potatoes will be sitting out for an extended period of time, more sweet potatoes should be prepared. Additionally, the other foods that will be on the menu should also be considered; if there are many side dishes, people will eat fewer sweet potatoes. The style in which the sweet potatoes are to be served will determine the type of pan that should be used to cook the sweet potatoes.

A 9×13 inch baking dish can hold 12 cups of sweet potatoes, and is suitable to serve 10-12 peoples. A half hotel pan can hold 24 cups of sweet potatoes. These pans can be selected based on the number of peoples who will be served the sweet potatoes.

When purchasing sweet potatoes, it is best to round up to the nearest whole medium sweet potato. Additionally, there is two medium sweet potatoes in every one pound of sweet potatoes. Some mistakes that may be made in calculating the amount of sweet potatoes that are needed for a meal may include purchasing the sweet potatoes based on how they look in the market instead of the weight of the sweet potatoes.

One pound of raw sweet potatoes will only serve three to five peoples for a meal. Additionally, another mistake may be to forget to account for the number of children who will be eating. Another mistake may be to use the measurements of the sweet potatoes that are prepared in a mashed form for those that is roasted, as the roasted sweet potatoes will yield less sweet potatoes than those that is mashed.

Finally, people may not account for the fact that buffets encourage guests to take servings of the food; more sweet potatoes would need to be prepared in this case. These rules could of been used to calculate the number of sweet potatoes that would be needed for a variety of events. For instance, for a potluck that will feature 30 peoples, where 15 percent of the people are children, and the sweet potatoes will be roasted and available as a buffet, the amount of raw sweet potatoes that would need to be purchased would be between 18 and 20 pounds of raw sweet potatoes.

This amount of raw sweet potatoes will provide enough roasted sweet potatoes to fill three sheet pans. However, if the recipe for the sweet potatoes is changed to a holiday casserole with marshmallows, the amount of sweet potatoes will need to be increased, as the marshmallows will increase the appeal of the sweet potatoes to the guests. The variety of sweet potatoes that will be used may alter the preparation of the sweet potatoes.

Orange-fleshed sweet potatoes holds their shape when roasted. White sweet potatoes are better for mashing recipes. Sweet potatoes should be stored in a cool, dark place to prevent them from sprouting.

If increasing the volume of the sweet potatoes is desired, the skin should be left on the roasted sweet potatoes. If preparing a sweet potato puree, the sweet potatoes should be deeply peeled before roasting. These rules and patterns can be used to prepare sweet potatoes for any size group.

For instance, if preparing a meal for six peoples, between four and seven pounds of sweet potatoes should be purchased. For a reunion of 50 people, between 30 and 55 pounds of sweet potatoes will be sufficient for the meal. For 72 peoples at a large buffet, many sheet pans of sweet potatoes will be needed; however, if the sweet potatoes are to be served family-style, there will be fewer sweet potatoes that would need to be prepared.

Thus, by calculating the amount of sweet potatoes based on the number of people, the preparation of the dish, and the style in which the sweet potatoes will be served, the cooks will ensure that there is enough sweet potatoes for each guest.
