Batch cooking
Also: meal prep, make-ahead cooking
Cooking components or whole dishes in larger quantities ahead of time, then storing them safely for later.
What it is
Batch cooking prepares base gravies, dals, rice, stocks, sauces, marinated proteins and doughs in bulk, then portions, cools and stores them. It is how restaurants serve a large menu quickly and how home cooks save weekday time.
Why cooks use it: It saves time and energy, reduces waste and makes complex meals quick on busy days.
The science
Safety depends on cooling quickly through the danger zone (5–60 °C), where bacteria multiply fastest, and reheating thoroughly. Spore-forming bacteria in rice (Bacillus cereus) and large meat dishes (Clostridium perfringens) are the main concerns.

Step by step
Plan dishes that freeze or keep well (curries, dals, gravies, stocks).
Cook in large, heavy pots; season slightly less than usual and adjust when reheating.
Cool quickly: spread into shallow containers or set the pot in iced water; cool rice within 1 hour.
Refrigerate within 2 hours (rice within 1 hour); label with name and date.
Freeze portions you will not eat within 3 days.
Reheat until steaming hot throughout (at least 75 °C), and reheat rice only once.
Heat and timing
- Batch cooking up to 5 °C · Fridge at or below 5 °C; freezer at -18 °C; reheat to at least 75 °C.
Time: Cooked food in the fridge: about 3 days (rice: 1 day); frozen: about 2–3 months for best quality.
How you know it’s right
- Containers labelled and dated
- Food chilled in shallow layers
- Reheated food steaming throughout
Common mistakes
- Leaving a large pot to cool overnight on the stove
- Putting very large hot batches straight into a small fridge
- Reheating rice more than once
- Freezing in one huge block
Troubleshooting
- Frozen gravy watery on reheating
- Simmer uncovered for a few minutes to reduce; potatoes and cream-based gravies freeze less well.
- Freezer burn
- Remove air from bags and use within 2–3 months.
Restaurant DNA
How professionals do it
Restaurants plan batch prep from par levels, cool food in blast chillers or ice baths, label everything with dates and use first-in-first-out rotation. Indian restaurants commonly batch-prepare base gravies and marinated proteins.
At home
A weekend session making onion-tomato masala, a dal and a stock, frozen in portions, covers many weekday meals.
General professional practice — not any particular restaurant’s recipe.
Food safety
- Cool cooked rice within 1 hour and keep it in the fridge no more than a day.
- Thaw in the fridge, not on the counter.
- Never refreeze thawed raw meat unless cooked first.
