Generally, Chicken Tortilla Soup can last for 3 to 5 days in the fridge, as long as it's stored properly in a covered container at a temperature of 40°F (4°C) or below. That's plenty of time to enjoy it for lunch or dinner, and even have some leftovers for the next day. Just make sure to label and date the container, so you know how long it's been sitting in there!
Now, you might be thinking, "What about freezing it? Can I just stash it in the freezer and forget about it?" Well, yes and no! Chicken Tortilla Soup can be frozen, but it's best to do so within 2 days of cooking, and it'll keep for 3 to 4 months in the freezer. Just be sure to thaw and reheat it safely, when you're ready to devour it again!
