Question: do cooked lentils need to be refrigerated?
Answer: You will want to store lentils in a sealed package or airtight container in a cool, dry, dark place. ... Discard any lentils that are exposed to dampness or insect activity. Much like rice, lentils absorb water and double in size when cooked. Cooked lentils may be refrigerated up to one week in a sealed container.
