Cooking Methods: The Practical To-Do List
Cooking Methods: what is worth doing, what is worth avoiding, and when to stop and see a doctor.
How the way you cook changes the fat, salt and nutrient content of a meal. The same ingredients can be a very different meal depending on method, usually because of what is added rather than what is lost.
Key takeaways
- Roasting and grilling: need little or no added fat
- Deep frying: adds substantial fat from the oil
- Most useful single change: Roast, grill, steam or microwave in preference to frying.
- Commonest mistake: Crowding a roasting tin, which steams the food instead.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
Do
- Roast, grill, steam or microwave in preference to frying
- Use the cooking water for gravy or soup to recover leached vitamins
- Measure oil with a spoon rather than pouring
- Finish with acid and spice rather than salt
Do not
- Crowding a roasting tin, which steams the food instead
- Boiling vegetables for long periods
- Adding salt throughout rather than tasting at the end
The numbers behind the list
The reasoning behind both lists, in numbers.
| Measure | Figure |
|---|---|
| Roasting and grilling | need little or no added fat |
| Deep frying | adds substantial fat from the oil |
| Steaming and microwaving | retain more water-soluble vitamins than boiling |
| Boiling | leaches vitamin C and B vitamins into the water |
| Key roasting technique | a single loose layer; a crowded tin steams |
If you change one thing
Roast, grill, steam or microwave in preference to frying. That is the opening item above. Doing only that is still doing something.

When to speak to a doctor
Cook poultry, pork, burgers and sausages until steaming hot throughout with no pink meat. Reheat leftovers until steaming hot, once only. People who are pregnant or immunosuppressed should be particularly careful with cooking temperatures and should avoid raw or lightly cooked eggs without the British Lion mark.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
