Question: How long can you let cooked hamburgers sit out before they become unsafe to eat?
Answer: You can safely leave cooked hamburgers out at room temperature for two hours -- or one hour if the temperature is above 90 degrees Fahrenheit -- says the United States Department of Agriculture.
Cooked burgers that have been sitting out for longer than 2 hours (or 1 hour above 90° F) should be discarded. The reason is that bacteria grow rapidly when cooked ground beef is kept at temperatures between 40° F and 140° F. To prevent foodborne illness, try to refrigerate the cooked burgers as soon as you can.
You can safely keep cooked hamburgers in the refrigerator for 3 to 4 days; they’ll also keep well in the freezer for at least 2-3 months.
