How much Sliced, Cubed, French Fried, or Mashed is in a Sweet Potato?

Many recipes will call for "1 cup of cubed sweet potatoes" or "1 cup of sliced sweet potatoes” or even "1 cup of mashed sweet potatoes" but it is not always easy to determine actually how many sweet potatoes are in a cup. In order to help make cooking easier we did some experiments to help tell you exactly how many sweet potatoes you need to buy.

To answer How many sweet potatoes in a cup we went to the grocery store to check out the produce section. After surveying the vegetable selection we discovered that 1 pound of sweet potatoes is equal to 2 large or 3 medium sweet potatoes. We decided to use a medium sweet potato for our measurements.

We found that it took 1.25 medium sweet potatoes to obtain 1 cup of sliced potato. When cubing, we needed 1.3 sweet potatoes to reach the 1 cup mark. However, when measuring for 1 cup of mashed, 2 whole sweet potatoes did the trick.

Today sweet potato fries are very popular in more trendy restaurants. When preparing sweet potato fries at home, it took 1.3 potatoes to result in about 1 cup.

Even though they are often confused, did you know that sweet potatoes and yams are not the same thing? They aren’t even distantly related! Sweet potatoes originated from the tropical Americas and are part of the morning glory family; whereas yams, which are native to Africa and Asia, are related to lilies and grasses.

Next time your recipe calls for a cup of mashed, sliced or diced sweet potatoes you’ll know how much you’ll need to purchase at the store to cover it. You can also use our conversion tool below for any custom how many sweet potatoes in a..." measurements you need. If you are peeling a lot of potatoes by hand you should definitely look into getting a good vegetable peeler to greatly speed up the process. I feel comfortable recommending the OXO Good Grips Swivel Peeler since I use it all the time at home!
