Lentils can be stored indefinitely but after a year their color will begin to fade and they will become dryer and take longer to cook. Also, keep in mind that it is uncertain how old the lentils are when they are purchased so it is a good idea to only store lentils for six months. Do not mix newly purchased lentils in with the lentils you have stored at home because the lentils you have been storing will be dryer than the ones you just purchased. Different degrees of dryness will cause the lentils to cook unevenly. Store in a sealable bag or airtight container in a cool dry area out of the direct sunlight. Cooked lentils can be stored in an airtight container and refrigerated for 4 to 5 days. Cooked lentils can also be stored in the freezer for up to six months, but freezing them may affect their texture when reheated.
