Mongolian Beef

Mongolian Beef, when freshly made and never opened, lasts about 3-4 days in the refrigerator. Once you've opened the packaging or started eating, it should ideally be consumed within 3 days, although it can technically last in the fridge for up to 4 days. If you've frozen the cooked Mongolian Beef, you've extended its life to about 2-3 months.

Telling if Mongolian Beef has gone rancid can require a minor inspection. Check the color first - if it has turned a different color, especially if it's gone grey or greenish, that's a sure sign it's bad. The smell is another giveaway. If it has a sour, potent smell that differs from its regular aroma - think rotten eggs - it's not safe to eat. If you're still unsure, a small taste test (without swallowing) could help, but it's best to err on the sidelines of caution if you're already suspecting it's spoiled.

• Store the Mongolian Beef in an airtight container once opened or cooked to prevent exposure to surrounding food odors in the fridge. • If freezing for longer shelf-life, use a freezer-safe container or bag. Try to remove as much air as possible from freezer bags to prevent freezer burn. • Division into meal-sized portions before freezing is a good way to avoid thawing more than you need at a time. Just ensure each portion is in its own air-tight, freezer-safe container or bag. • Always let the Mongolian Beef cool down before storing it in the refrigerator or freezer. Hot food can increase the overall temperature of your fridge causing other foods to spoil faster. • Ensure that the temperature of your refrigerator is set below 40°F (4°C) and your freezer at or below 0°F (-18°C) to ensure proper food storage.
