If you store your lemon meringue pie in the refrigerator at a temperature of 40°F (4°C) or below, it can last for 3 to 5 days. But, let's be real, who can resist a slice (or two) of pie for that long? It's like trying to save a cookie for later - it's just not happening.
However, if you want to extend the life of your pie, you can try storing it in an airtight container or wrapping it tightly in plastic wrap. This will help keep it fresh for a longer period, but it's not a guarantee - after all, time waits for no pie. The filling and meringue can start to separate and become less stable, affecting the overall texture and taste.
