Can You Reheat Broccoli?
Written by Jordan Morley · Reviewed against FSA/NHS reheating guidance · Last updated 28 October 2026
Yes, you can reheat broccoli safely — once, until piping hot. The old warnings about reheating vegetables are myths.
What makes it safe (or not)
Reheating broccoli is safe. You may have heard that vegetables like spinach or beetroot become dangerous when reheated because of nitrates — food safety agencies consider this a myth at normal dietary levels for adults; the nitrate caution applies mainly to preparing food for young babies. Follow the standard rules — cool within 2 hours, refrigerate, use within 2 days, reheat once until piping hot — and reheated broccoli is fine.

Common questions
Isn't reheating broccoli dangerous because of nitrates?
For healthy adults, no — the nitrate warning is a persistent myth at normal dietary levels. The caution about reheated high-nitrate vegetables applies mainly to food prepared for babies under about 12 months.
What is the best way to reheat broccoli?
Microwave covered with a splash of water, or steam it briefly, until steaming hot throughout. It will be softer than fresh.
Can you reheat broccoli twice?
The once-only rule applies to all reheated food, broccoli included.
Can you reheat broccoli in the microwave?
Yes — covered, with a splash of water, stirring once. It's the quickest way to get vegetables piping hot without overcooking.
Can you eat broccoli cold?
Yes — properly stored cold cooked vegetables are fine within 2 days, straight from the fridge.
How long can I keep leftover broccoli 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 broccoli instead of reheating it?
Yes. Cooled promptly and frozen in portions, it keeps for around 1–2 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.
