Buy a cast iron frying pan: choose the right material, size and model for everyday cooking

A cast iron frying pan can be used on the hob, in the oven, on the barbecue and, where suitable, on an induction hob. At the same time, the material has characteristics that do not suit every household: cast iron is heavy, retains heat for a long time and responds more slowly to changes in temperature.

When buying, three common mistakes can often lead to unnecessary costs:

  • Focusing only on the coating: An enamelled cast iron frying pan generally does not require traditional seasoning. However, the enamel can be damaged by hard knocks, metal utensils or sudden changes in temperature.
  • Underestimating the weight: A 23 cm cast iron frying pan can already weigh around 1.93 kg. An additional handle is therefore practical if you regularly toss food or lift the pan out of the oven.
  • Confusing diameter with usable cooking surface: The stated diameter does not always describe the actual usable frying area. Check the base, rim and handle dimensions before buying.

Which features matter most in a cast iron frying pan

1. Raw or enamelled cast iron?

A traditional cast iron frying pan without enamel is usually seasoned. Oil and heat create a protective patina. This can be affected by incorrect cleaning or prolonged exposure to moisture. After washing, the pan must be dried completely and, depending on the model, lightly oiled.

An enamelled cast iron frying pan, on the other hand, has a glass-like protective coating. It is neutral in taste and is also suitable for acidic ingredients such as tomatoes or wine. Cleaning is easier, although abrasive cleaning products, steel wool and sudden temperature changes should still be avoided. If there is visible chipping, the cookware should no longer be used.

2. Hob, oven and barbecue suitability

For UK households, versatile use is often a practical choice. Look for specific information on:

  • gas, electric, ceramic and induction hobs
  • oven temperature in degrees Celsius
  • use on the barbecue
  • dishwasher suitability
  • handle material and heat protection

An ovenproof frying pan should only be used up to the stated maximum temperature. The manufacturer’s instructions are particularly important for enamelled models. Cast iron handles also become hot and require oven mitts or heat-resistant gloves.

If you often braise, reduce sauces or keep food warm, you may prefer a frying pan with a lid. A glass lid makes it easier to monitor the food, while a matching cast iron lid helps retain heat. However, not every frying or serving pan is supplied with a lid.

3. Choosing the right size

The size should match your portion sizes and hob:

  • A small 12 cm frying pan is suitable for an egg, small side dishes, individual desserts or serving food directly at the table.
  • A 16 cm frying pan is practical for tapas, small portions and side dishes.
  • A 23 cm frying pan has room for one or two portions and can generally still be used comfortably in the oven.
  • A 26 cm frying pan is more versatile for meat, fish, vegetables and barbecue dishes at home, but requires more storage space and is heavier.

A cast iron grill pan also requires a sufficiently large cooking zone that heats evenly. The ridges create grill marks but reduce the area in direct contact with the food. For sauces or very flat foods, a smooth stainless steel frying pan may be more suitable.

Cast iron or stainless steel frying pan: which option is right for you?

A stainless steel frying pan with a multi-layer construction, such as stainless steel–aluminium–stainless steel, is generally lighter and responds more quickly to temperature changes. It is a practical alternative for anyone who often tosses food or prefers straightforward cleaning. Without a traditional non-stick coating, however, stainless steel requires the right temperature and amount of fat to reduce sticking when cooking delicate foods.

Cast iron, by contrast, stands out for its weight and long-lasting heat retention. This is useful for searing, braising and serving. For both materials, information about the base, handle, oven temperature and cleaning is more important than general claims about durability.

Care and safe use

  • Do not place a hot pan on cold, wet or delicate surfaces.
  • Clean enamelled surfaces with a soft sponge and mild cleaning product.
  • Allow the pan to cool and dry completely before storing it.
  • Only handle handles and lids with suitable heat protection.
  • Before buying, check that the information on oven temperature, dishwasher and barbecue use actually applies to the model you want.

Frequently asked questions about cast iron frying pans

Does an enamelled cast iron frying pan need seasoning?

As a rule, an enamelled surface does not require traditional seasoning in the same way as raw cast iron. Before first use, washing it with warm water and mild washing-up liquid is normally sufficient. The care instructions provided by the manufacturer always take priority.

How long does a cast iron frying pan last?

Its service life depends on the material, enamel, temperature control and care. Cast iron itself is robust, while damaged enamel or a warped base can restrict further use. Avoid knocks, sudden temperature changes and aggressive cleaning products.

Does a cast iron frying pan use more energy?

Cast iron generally takes longer to heat up, but then retains its heat for longer. If you warm the pan slowly over a medium setting and then reduce the temperature, you can make targeted use of its heat retention. On an induction hob, the base must sit flat and be compatible with the hob.
