How long does cooked potatoes last in fridge? Here's everything you need to know

Cooked potatoes are a staple in many households due to their versatility and the variety of ways they can be prepared. From mashed to roasted, potatoes can be a side dish or the main event in a meal. An important consideration, once you've cooked a surplus of potatoes, is how to store them safely and how long they will last in your refrigerator.

Proper storage not only ensures that your potatoes remain delicious but it also prevents foodborne illness. Here's what you need to know about storing cooked potatoes in the fridge and the best practices to maximize their shelf life.

1. The general rule of thumb for cooked potatoes is that they will last in the fridge for about 3 to 5 days when stored properly. This applies to all types of cooked potatoes, including baked, boiled, roasted, and mashed potatoes.

2. Temperature plays a crucial role in how long your cooked potatoes will last. The refrigerator should be set to 40°F (4°C) or below to slow the growth of bacteria.

3. The way you store the potatoes can also impact their shelf life. Make sure to use airtight containers or heavy-duty aluminum foil or plastic wrap to cover them well. This helps to keep out moisture and other contaminants.

Here are several factors that can influence how long your cooked potatoes remain edible:

1. The type of potato can make a slight difference. Waxy potatoes like red or new potatoes generally hold up better in the fridge because they have a lower starch content compared to starchy potatoes like russets.

2. How the potatoes were cooked will also matter. For example, potatoes that are cooked with a lot of dairy (like mashed potatoes with butter and milk) may not last as long as plain boiled potatoes due to the quicker spoilage rate of dairy products.

3. The presence of additional ingredients could also affect their fridge life. Cooked potatoes with added acids, like vinegar or lemon juice, may last a bit longer due to the preservative nature of these ingredients.

1. Cool your potatoes. Allow the cooked potatoes to cool to room temperature before storing them in the fridge to prevent the growth of bacteria.

2. Transfer them to a suitable container. Place your cooled potatoes in an airtight container, or wrap them securely in foil or plastic wrap.

3. Avoid storing potatoes with onions as this can cause them to spoil faster.

4. If the potatoes were cooked in a liquid, such as a soup or stew, the liquid can actually help to preserve them for a longer period.

When assessing whether your cooked potatoes are still good to eat, look for the following signs:

1. Off-smell: An unusual or foul odor is a strong indicator that they've gone bad.

2. Mold: Any visible mold growth means the potatoes should be discarded immediately.

3. Texture changes: If the potatoes have become extremely soft or slimy, they are likely no longer safe to eat.

4. Taste: If they taste sour or off in any way, it's best to err on the side of caution and throw them out.

Proper storage of cooked potatoes is critically important for both quality and food safety. If kept in the fridge, they can be a convenient and delicious part of meals for several days. However, always perform a quick check for any signs of spoilage before reheating and consuming leftovers. By adhering to these guidelines, you can safely enjoy your cooked potatoes for as long as possible.
