How long can you leave a meringue pie out?

Meringue pie can be left out at room temperature for about 2 to 4 hours. Beyond that, it’s best to refrigerate it to prevent the meringue from weeping or becoming soggy. If you need to store it for longer, keep it in the refrigerator and consume it within 1-2 days for the best texture and flavor. Avoid freezing meringue pies, as the texture can be negatively affected when thawed.
