How to Store and Reheat Cooked Beans and Lentils Safely

Cool cooked beans and lentils quickly, store them covered, and reheat them to 165°F or hotter.

Editors Miraç Eroğlu, Utku Eroğlu

Key points
  • Refrigerate cooked beans within 2 hours, or within 1 hour if the surroundings are hotter than 90°F [4].
  • Divide large batches into shallow containers and cover them loosely while hot [3].
  • For the most conservative refrigerator limit, use cooked leftovers within three to four days [3].
  • Cooked beans can be frozen for up to 6 months, but freezing does not reset the clock [1][3].
  • Reheat leftovers to 165°F or hotter before serving [4].

Start with properly cooked beans and lentils

Safe storage begins with cooking. Cook food to a safe internal temperature to kill harmful germs that might be in it [4]. After soaking and rinsing, dried beans are simmered covered in fresh water for 1 ½ to 2 hours until tender [1]. Lentils do not need to be soaked, which makes them a good option when you are preparing dried beans in a rush [2].

If you soak dried beans, one source describes a cold water soak of 10 cups of water per pound (2 cups) of dry beans, left overnight or at least 8 hours [1]. Most beans rehydrate to triple their dry size, so start with a large pot [1]. One cup of dry beans makes 2 to 3 cups of cooked beans, which helps you judge how many containers you will need [1].

Canned beans do not require additional cooking [1]. Temperatures in this guide are in °F, as the sources give them.

Cool cooked beans and lentils quickly

Bacteria can multiply rapidly between 40°F and 140°F, the danger zone, so the goal is to limit the time cooked food spends there [3][4]. Foods cooked in large batches and held at unsafe temperatures have been linked to outbreaks of C. perfringens food poisoning [4]. Some pathogens cannot be destroyed by cooking and reheating once they have developed [3].

Refrigerate cooked beans and other leftovers within 2 hours of cooking [2][3][4]. If the food is in temperatures hotter than 90°F, such as in a hot car or at a picnic, refrigerate it within 1 hour [4]. Do not keep cooked food at room temperature if it will not be served and eaten soon [4].

  • Separate a large pot into smaller portions in shallow pans or bowls so the food cools quickly [3].
  • Cover the portions loosely while they are hot to allow the food to cool faster [3].
  • For soups and stews, use an ice bath to cool them if necessary [3].
  • Get the portions into the refrigerator within 2 hours of cooking, or within 1 hour if the surroundings are hotter than 90°F [4].

Refrigerate: containers, temperature and time limits

Once the food is cool, cover it in airtight packaging or sealed storage containers to keep bacteria out and retain moisture [3]. Refrigerate food at 40°F or colder [4]. A refrigerator set between 36°F and 38°F keeps food below 40°F [3]. Do not overfill the refrigerator, and allow air to circulate around the food [3].

The sources give slightly different time limits for cooked beans. One says leftover cooked beans keep in the refrigerator for up to 5 days in a covered container [1]. Another says to use refrigerated cooked beans within 3 to 5 days [2]. The USDA recommends storing cooked leftovers for no more than three to four days [3]. For the most conservative choice, use the three to four day window [3].

Do not eat leftovers that are green, moldy, slimy, or smell bad, regardless of how old they are [3]. A leftover can look fine after four days, yet some pathogens cannot be seen, smelled, or tasted [3].

Freeze for longer storage

Cooked beans freeze well [2]. They can be frozen for up to 6 months in airtight containers [1]. Cooking extra dry beans and freezing half for later is one way to save time [2]. Another source suggests cooking enough dry beans for more than one meal and freezing the rest [1].

Freezing does not reset the clock [3]. For example, if soup was in the refrigerator for 2 days before it was frozen, it should be used within 1 to 2 days after it is thawed [3]. After thawing, add a little moisture or seasoning to restore the flavor and consistency of the beans [1].

Reheat to 165°F or hotter

Reheat leftovers to 165°F or hotter before serving [4]. If you cook ahead, the same guidance says to refrigerate the food at 40°F or colder before serving and to reheat it to 165°F or hotter before serving [4]. A county health department document says a stem-type thermometer accurate from 0°F to 220°F must be provided, properly calibrated, and used to ensure proper cooking and holding temperatures [5].

That document also says proper cooking equipment must be used to reheat foods [5]. It says hot-holding equipment is to be used only for holding foods hot once they are cooked or reheated [5].

If you keep reheated beans or lentils hot for serving, keep them at 140°F or hotter [4]. Keep cooked foods at 40°F or colder or 140°F or hotter [4].

Store dried and canned beans

Keep canned and dried beans in a cool, dark place [2]. Store dried beans in hard, closed containers to protect them from pests [2]. Dried beans can be stored at room temperature for up to 6 to 12 months in a cool, dry place in airtight containers [1].

Storage times for beans, as stated in the sources

Refrigerator, cooked beans in a covered containerUp to 5 days[1]
Refrigerator, cooked beans3 to 5 days[2]

Dried beans in airtight containers, cool and dry placeUp to 6 to 12 months[1]

Frequently asked questions

Can I leave cooked beans on the counter to cool completely first?

Do not keep cooked food at room temperature if it will not be served and eaten soon [4]. Refrigerate leftovers within 2 hours of cooking, or within 1 hour if the food is in temperatures hotter than 90°F [4]. Dividing the food into shallow pans or bowls and covering it loosely while hot helps it cool faster [3].

How long do cooked beans and lentils last in the refrigerator?

The sources give up to 5 days, 3 to 5 days, and three to four days for cooked leftovers [1][2][3]. The most conservative of these is three to four days [3].

Can I eat leftovers that look and smell fine after four days?

Some pathogens cannot be seen, smelled, or tasted, so appearance alone is not a reliable guide [3]. The USDA recommends storing cooked leftovers for no more than three to four days [3].

Does freezing restart the storage time?

No, freezing does not reset the clock [3]. Time already spent in the refrigerator counts toward how soon the food should be used after thawing [3].

What temperature should reheated beans reach?

Reheat leftovers to 165°F or hotter before serving [4].
