If I do my apple pie tonight can I leave it out or do I need to put in in the fridge
If you just baked your apple pie tonight, you can leave the apple pie out at room temperature for up to two days. Just make sure you keep the pie tightly covered. After two days, you need to store it in the fridge.
You should leave it out or the crust will get soggy. I don't recommend ever putting in the refrigerator. Only custard pies need to be refrigerated.
