Can You Reheat Gravy?
Written by Jordan Morley · Reviewed against FSA/NHS reheating guidance · Last updated 28 October 2026
Yes, you can reheat gravy — bring it fully to a simmer/boil, stirring, and reheat only once.
What makes it safe (or not)
Sauces and liquids are actually among the safest things to reheat, because you can stir them and see the whole volume steaming and bubbling, which shows it is hot all the way through. The standard rules still apply: cool within 2 hours of cooking, refrigerate, and reheat once only. Cream- and egg-based sauces need gentler heat to avoid splitting, but must still get piping hot throughout.

How to reheat gravy safely
- Refrigerate gravy within 2 hours of cooking; use within 2 days.
- Reheat in a pan over medium heat, stirring regularly.
- Bring it to a full simmer — every part piping hot — or 75°C (165°F) if using a thermometer.
- Serve immediately; discard leftovers rather than reheating twice.

Common questions
Can you reheat gravy twice?
No — reheat once only. Freeze in portions if you won't use it all.
What is the best way to reheat gravy?
Heat it in a pan over a medium heat, stirring, and bring it to a gentle simmer so the whole pot is bubbling and piping hot. In the microwave, cover and stir every minute or so, because microwaves heat unevenly and leave cold spots.
Can you reheat gravy in the microwave?
Yes — in bursts, stirring between each, until it's bubbling throughout. Stirring is essential because microwaves heat liquids unevenly.
Why did my gravy split when reheated?
Cream and egg-based sauces split under fierce heat. Reheat gently, stirring constantly — the safety requirement (piping hot) is the same, it just takes a little longer at lower heat.
Can you freeze gravy instead?
Most sauces freeze well for 2–3 months. Defrost in the fridge and bring fully to a simmer to serve — that counts as your one reheat.
How long can I keep leftover gravy 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.
Can I freeze gravy instead of reheating it?
Yes. Cooled promptly and frozen in portions, it keeps for around 2–3 months for best quality (USDA FoodKeeper), and stays safe beyond that. Defrost in the fridge, then reheat once until piping hot. See our freezing guide for the details.
