How Long Do Cooked Potatoes Last In The Fridge?

The shelf life of cooked potatoes depends on several factors, including how they were cooked, how they were stored, and the temperature of your fridge. In general, cooked potatoes will last for 2 to five days in the fridge and 2 to 3 months in the freezer. However, this timeline can vary depending on the factors mentioned above.

Factors That Affect Shelf Life

The way potatoes are cooked can affect their shelf life. Boiled potatoes will last longer than mashed or roasted potatoes because they have a lower moisture content. The amount of time that cooked potatoes spend at room temperature also affects their shelf life. If you leave cooked potatoes out for more than two hours, bacteria can start to grow, and they may spoil more quickly in the fridge.

The temperature of your fridge is also important. If your fridge is too warm, cooked potatoes will spoil more quickly. Make sure your fridge is set to below 40°F (4°C) to keep your food fresh for longer.

There are several signs that cooked potatoes have gone bad. These include a sour smell, mold growth, and a slimy texture. If you notice any of these signs, it’s best to throw the potatoes away.

Tips for Storing Cooked Potatoes

To ensure that your cooked potatoes last as long as possible, it’s essential to store them correctly. Here are some tips to help you store your cooked potatoes:

  • Store cooked potatoes in an airtight container. This will help prevent them from drying out or absorbing other flavors in your fridge.
  • Keep cooked potatoes away from raw meat and seafood in your fridge. This will help prevent cross-contamination.
  • Don’t store potatoes in aluminum foil. This can cause them to oxidize and turn black.

Can You Freeze Cooked Potatoes?
