Equipment

  • 1 cutting board
  • 1 chef's knife
  • 1 airtight food storage container

Materials

  • 1 sweet potato

Instructions

Preparation

  • Wash your hands for at least 20 seconds before you begin.  Make sure you have a clean cutting board, chef's knife, and storage equipment on hand.  This is key to ensuring your sweet potatoes stay fresh for an extended period.  
  • If desired, use a vegetable peeler to remove the skin from the sweet potatoes.  You may need to rinse the peeled sweet potatoes to remove any dirt or debris.  Be sure to dry them off with a towel before cutting.  This will remove the excess water and avoid a slippery situation.
  • Cut the potatoes according to your cooking needs.  For example, you can slice them to make sweet potato "toast", cube them for stews and salads, or cut them into strips to make sweet potato fries.

How to Store Cut Sweet Potato in the Fridge

  • If you plan to roast or bake, store them dry in an airtight container.  This is the better technique when making crispy oven-roasted sweet potatoes.
  • If you plan to boil or steam, store them in an airtight container full of cold water to prevent any browning (oxidation) and dehydration.

Usage

  • Check for any browning or softening and discard those pieces.  If there is any odor, your stored sweet potatoes are no longer fresh and should be discarded.
  • If stored in water, drain them before use.  If cooking with dry heat (not recommended if you want a crispy result), pat them dry with a kitchen towel to remove excess moisture.  Use parchment paper to prevent sticking to the baking sheet.
  • Add oil right before roasting.  Avocado oil is best for high-heat cooking while olive oil can be used for lower-heat cooking (or as a finishing oil).  Anything above 400 degrees Fahrenheit would be considered high heat.  
  • When ready to cook, dry herbs can be added in advance while fresh herbs and spices should be added after cooking.

Notes

  • Do not add any oil or seasoning when preparing for storage.
  • Store immediately after cutting to avoid browning.
  • To make cutting sweet potatoes easier and safer, use a sharp chef's knife.  
  • To avoid food waste, plan to use your pre-cut sweet potatoes a couple of times during the week if you have more than you need for a single recipe.
