Dehydrated hash browns save freezer space because the lack of moisture allows you to store the shredded potatoes in your pantry with other dry goods. The potatoes shrink down as moisture is removed, so you can also store a greater amount of potatoes in a small space. Before cooking dehydrated hash browns, they must be rehydrated to restore the moisture. You can use them to make fried hash browns for breakfast or add them to a casserole. They are often sold in cartons in the dry goods section of your grocery store. You can even dehydrate your own potato harvest.

Place the dehydrated hash browns in a bowl. Bring a pot of water to a boil. Pour the water over the hash browns so the potatoes are completely submerged. Store-bought dehydrated hash browns sold in cartons can usually be hydrated inside the carton without need for a bowl.

Soak the potatoes in the hot water for about 10 to 15 minutes until rehydrated. The potatoes swell as they absorb the water.

Drain off the remaining water through a colander. Wrap the hash browns in a linen dish towel and wring the towel to squeeze out excess water from the potatoes. While you want to ensure the potatoes are rehydrated sufficiently, removing the excess water allows you to make crispy hash browns instead of steaming the potatoes.

Heat oil or butter in a non-stick skillet. Arrange the hash browns in a single layer and fry over medium heat for about five minutes or until the hash browns brown and become crispy on the bottom.

Flip the hash browns and cook the other side until crispy and brown. It helps to divide the hash browns in the pan into several smaller sections that are easier to flip.

Items you will need

  • Bowl
  • Pot
  • Colander
  • Linen dish towel
  • Skillet
  • Oil or butter
  • Spatula


  • Guidelines for rehydration might vary among different dehydrated hash browns manufacturers, so read the label carefully for any differences. For example, some might instruct to use lower temperature water and soak the potatoes for a longer period of time. This achieves the same goal of restoring moisture and softening the potatoes.
  • Hash browns used for a casserole usually taste best when cooked slightly in a skillet before adding to the casserole dish and baking. Follow the casserole recipe for specific instructions and treat the rehydrated hash browns as fresh.
