Can You Reheat Burgers?
Written by Jordan Morley · Reviewed against FSA/NHS reheating guidance · Last updated 28 October 2026
Yes, you can reheat burgers — but only once, and it must reach 75°C (165°F) and be piping hot all the way through.
What makes it safe (or not)
Reheating burgers is safe when you follow the core food safety rules. The risk comes from bacteria that multiply while food sits in the 'danger zone' between 8°C and 63°C — so what matters is how quickly it was cooled, how it was stored, and whether reheating gets it properly hot. Each reheat cycle gives bacteria another trip through the danger zone, which is why the FSA advises reheating food only once.

How to reheat burgers safely
- Take burgers from the fridge and reheat it straight away.
- Reheat in the microwave, oven or pan until steaming hot throughout — 75°C (165°F) in the centre. Stir or turn partway through so there are no cold spots.
- Check the middle: it should be piping hot, not just warm.
- Eat immediately, and throw away anything left over — never reheat burgers twice.

Common questions
Can you reheat burgers twice?
No — the FSA advises reheating food only once. Each additional cooling and reheating cycle gives bacteria more time in the temperature danger zone. Portion it out so you only reheat what you'll eat.
What is the best way to reheat burgers?
Reheat in a hot oven or covered pan until steaming hot all the way through. Do not rely on the outside looking hot: the centre must reach 75°C.
Can you reheat burgers in the microwave?
Yes — the microwave is fine as long as the result is piping hot throughout. Stir halfway, use a cover to trap steam, and let it stand a minute so the heat evens out before checking the centre.
How do I know burgers are hot enough?
The centre should be steaming and too hot to eat straight away — 75°C (165°F) on a food thermometer. If the middle is lukewarm, keep going.
Can you eat burgers cold instead?
If it was properly cooked, cooled within 2 hours, and kept refrigerated, eating it cold within its fridge life is generally fine — the reheat rules exist for reheating, not for chilled eating.
How long can I keep leftover burgers before reheating?
Within 2 days in the fridge is the NHS/FSA advice for cooked leftovers (the US USDA allows 3–4 days). Cool it within 1–2 hours of cooking and keep the fridge at 5°C or below.
