How many cups of sweet potatoes in a 29 oz can?

Quick Answer

There are approximately 3 cups of sweet potatoes in a 29 ounce can. A standard 14-16 ounce can of sweet potatoes contains around 1.5-2 cups. Since a 29 ounce can is double the size, it will contain roughly double the amount of sweet potatoes, which is 3 cups. The exact amount can vary slightly depending on the brand, size of the sweet potato pieces, and how densely they are packed in the can. But in general, a 29 ounce can will yield about 3 cups of sweet potatoes when drained.

Calculating Cups per Ounce

To calculate how many cups are in a 29 ounce can of sweet potatoes:

  • A standard cup of mashed, cooked sweet potatoes weighs approximately 8 ounces.
  • So if 1 cup = 8 ounces, then 29 ounces / 8 ounces per cup = approximately 3.625 cups.
  • Rounding down, that’s about 3 cups of sweet potatoes in a 29 ounce can.

You can use this same method to determine cups per ounce for any canned vegetable. Just remember that 1 cup of a canned product weighs about 8 ounces on average.

Typical Can Sizes

Here are some common can sizes for sweet potatoes and the approximate cups they contain:

Can Size Cups (Drained)
14-16 ounces 1.5-2 cups
29 ounces (family size) 3-3.5 cups
40 ounces 4-5 cups

As you can see, a 29 ounce can falls in the middle and contains about 3-3.5 cups when drained. The exact amount depends on the brand and how the sweet potatoes are packed into the can.

Tips for Canned Sweet Potatoes

When buying and using canned sweet potatoes, keep these tips in mind:

  • Look for cans with sweet potatoes packed in juice rather than heavy syrup, to avoid added sugar.
  • Drain and rinse the sweet potatoes to remove excess sodium and sugar.
  • For a healthier option, look for low-sodium or no-salt-added canned sweet potatoes.
  • Use drained canned sweet potatoes in soups, casseroles, oatmeal, etc. They work well in both savory and sweet dishes.
  • Substitute canned sweet potatoes 1:1 for fresh potatoes in any recipe.
  • Store unopened cans in a cool, dry pantry up to 1 year. Refrigerate leftovers in a sealed container up to 4 days.

Canned sweet potatoes are a convenient and healthy pantry staple. With about 3 cups per 29 ounce can, they provide ample roasted sweet potato flavor and nutrients without the prep work. Rinsing and draining removes excess sugar and salt for a boost of fiber, potassium, vitamin A, and more.

Cost Comparison of Canned vs. Fresh

Canned sweet potatoes provide convenience and value compared to fresh sweet potatoes. Here is a cost comparison:

Sweet Potatoes Average Cost
29 oz can (3 cups) $2-$3
3 cups fresh sweet potatoes $3-$4

As you can see, a 29 ounce can containing 3 cups of sweet potatoes costs comparable or even less than fresh sweet potatoes. Plus canned saves prep time peeling, chopping and roasting fresh potatoes.

However, fresh sweet potatoes have a more firm, crisp texture when roasted vs. the softened texture of canned. Choose canned or fresh depending on your recipe needs and budget.

Storing Leftover Canned Sweet Potatoes

Here are some tips for storing leftover canned sweet potatoes:

  • Transfer unused canned sweet potatoes and juice to an airtight container. Refrigerate up to 4 days.
  • To freeze, drain the sweet potatoes well and pack into freezer bags or containers. Freeze up to 6 months.
  • Reheat leftover canned sweet potatoes on the stovetop, in the microwave, or in the oven until heated through.
  • Add a splash of water or broth to prevent leftovers from drying out when reheating.
  • Use leftover canned sweet potatoes within a week for the best quality and flavor.
  • Avoid letting sweet potatoes sit in their can juice for extended periods, as this can cause texture changes.

With proper storage in the refrigerator or freezer, leftover canned sweet potatoes can be enjoyed throughout the week in quick sides, snacks and meals.
