If you have Eggo waffles and they are homemade, you can keep them in the refrigerator for 5 to 7 days and 1 day at room temperature. If the waffles are in a package, store them in the pantry for more than 7 days, and do not put them in the fridge. Frozen Eggo Waffles can stay in the pantry for 1 day and 3 to 5 days in the fridge.
