Question: how long can you eat leftover ground beef?
Answer: Can I refrigerate or freeze leftover cooked hamburgers? How should they be reheated? If ground beef is refrigerated promptly after cooking (within 2 hours; 1 hour if the temperature is above 90 °F), it can be safely refrigerated for about 3 or 4 days. If frozen, it should keep its quality for about 4 months.
