A cast iron skillet is one of those purchases you make once and keep forever. This guide covers size selection, what to look for when buying, and how to care for your pan so it lasts generations. If the seasoning has started shedding black flakes, there is a separate guide to why cast iron seasoning flakes off and how to rebuild it.

If a pan has come out of the oven tacky, there is a separate guide to cast iron that is sticky after seasoning. This guide follows the seasoning-to-rust-to-reseasoning cycle that cast iron owners actually run into, rather than stopping at what the manufacturer’s care card says.

What Size Cast Iron Skillet Do You Actually Need?

6-inch: Single-serve only

Good for a single egg or individual skillet dessert. Not practical as an everyday pan — too small for most meals.

8-inch: Right for one or two people

Comfortable for two eggs side by side, a small steak, or a couple of fish fillets. Lighter than larger sizes, which matters more than most people think once you’ve been using cast iron for a while.

10-inch: The one most people should buy

The most versatile size. A 10-inch skillet handles a full breakfast for two, two large steaks side by side, sautéed vegetables, or a shakshuka for four. Large enough to be genuinely useful, light enough to be practical. If you’re buying one cast iron skillet, buy a 10-inch.

12-inch: For families and batch cooking

Fits a whole spatchcocked chicken or a large shakshuka for six. The trade-off is weight — a quality 12-inch typically weighs 3.5–4.5 kg (8–10 lb), which is genuinely difficult to transfer from oven to counter one-handed safely.

Pre-Seasoned vs. Raw Cast Iron

Almost every cast iron skillet sold today comes pre-seasoned — the manufacturer has applied thin coats of oil to the cooking surface and baked them at high temperature to create the initial non-stick layer. Pre-seasoned pans are ready to use straight out of the box and improve significantly with every cook. For most people, a pre-seasoned pan from Lodge or Victoria is the right starting point.

Surface Texture: Rough vs. Smooth

Traditional sand-cast skillets (Lodge, Victoria) have a slightly pebbly surface texture — a result of the casting process, not a quality defect. That texture smooths out over time as seasoning builds up. A well-used Lodge skillet cooked on weekly for a year is noticeably smoother and more non-stick than a brand-new one.

Premium brands like Finex and Stargazer machine-grind the cooking surface to a smooth finish before seasoning. More non-stick from day one, but typically three to five times the price of a Lodge equivalent. For most everyday cooking, Lodge gets there within a few months.

Cast Iron vs. Other Cookware

Cast iron is the right tool for searing, hob-to-oven cooking, and long slow braising. It’s not the right tool for delicate sauces (iron can react with acidic ingredients) or for eggs if the seasoning isn’t yet well established. High-heat searing also produces real smoke, so if you cook cast iron often, good kitchen ventilation matters more than it does with most other cookware.

If you’re trying to decide between a cast iron skillet and a cast iron dutch oven, my best cast iron dutch oven guide covers the case for each and reviews the top picks. I also have a detailed Lodge vs Le Creuset dutch oven comparison if you’re weighing whether the price premium is worth it. For the health question, my cast iron vs ceramic cookware comparison covers both materials in depth.

Which Brands Are Worth Buying?

Lodge ($25–$50)

See my full review of the Lodge 12-Inch Seasoned Cast Iron Skillet for a deeper look at performance and long-term ownership.

The default recommendation for good reason. Lodge has been making cast iron in Tennessee since 1896. Consistent, well-priced, and well pre-seasoned.

The main downside: it ships with a rougher, pebbly surface than the pricier brands, so eggs stick more in the first few months until it smooths out with use. Buy a Lodge if you’re buying your first cast iron skillet and don’t mind that early break-in period.

Victoria ($25–$45)

A Colombian brand that’s become a popular alternative to Lodge at a similar price. Victoria uses a slightly thinner casting, which some people prefer for the reduced weight. Very competitive quality at the price.

Field Company and Stargazer ($80–$150)

American-made skillets with machined smooth surfaces and designs that are genuinely lighter than Lodge or Victoria. The machining shows in the finish, and the price reflects it. Worth it if you cook on cast iron regularly and want the extra smoothness from day one.

Caring for Your Cast Iron Skillet

After Each Use

Rinse under hot water while still warm. Use a stiff brush or chainmail scrubber for stubborn bits — both are fine and won’t damage the seasoning.

A small amount of dish soap is also fine on a well-seasoned pan; the idea that soap ruins cast iron is a persistent myth. Dry immediately and completely — cast iron rusts quickly when left wet. While still warm, wipe a very thin layer of oil over the cooking surface.

If It Rusts

Rust is not the end. Scrub the affected area with steel wool, wash, dry immediately, and re-season by applying a thin coat of oil and baking at 230°C for an hour. A heavily rusted pan can be fully restored in an afternoon. The same process applies to a dutch oven — see my guide on cleaning a cast iron dutch oven.

Frequently Asked Questions

Can I use cast iron on an induction hob?

Yes. Cast iron is magnetic and works on induction without any adaptor. It heats more slowly than on gas, but once hot it retains heat exceptionally well.

Can I cook acidic foods in cast iron?

Occasionally and briefly, yes. A quick tomato sauce for 15 minutes is fine. A two-hour tomato braise isn’t — the acid will strip the seasoning and can impart a metallic taste. Use enamelled cast iron or stainless for long-cooked acidic dishes.

How do I know when my cast iron is well-seasoned?

The surface should look dark, feel slightly smooth rather than rough and pebbly, and have a slight sheen. Eggs should slide around with minimal sticking. Cast iron will never be as reliably non-stick as PTFE-coated pans — that’s expected, it’s a different tool for different tasks.

How often should I re-season the whole pan in the oven?

Only if the seasoning has been damaged — by rust, extended acidic cooking, or harsh cleaning. For a pan in regular use that’s oiled after each cook, oven re-seasoning should be a rare event, not a routine step.

How This Guide Was Put Together

Plainly: this is a research-based guide, not a hands-on test. I have not seasoned and used each of these pans, and nothing here should be read as a report from my own kitchen.

What it rests on: the metallurgy and physics of cast iron, which are well documented and not in dispute – heat capacity, the polymerisation that makes seasoning work, and why surface finish affects how quickly a pan becomes non-stick; along with manufacturer specifications for weight, diameter and factory seasoning; and the complaint patterns across verified-purchase reviews for pans in this category.

What I could not establish: anything about long-term seasoning behaviour from direct experience. The chemistry is documented; how a specific pan behaves after five years in a specific kitchen is not something this guide has measured.

Cooking Techniques: Getting the Most from Your Cast Iron

Searing Meat

Cast iron is the best home kitchen tool for searing. The key is temperature: get the pan properly hot before the meat goes in — about 3–5 minutes over medium-high heat. A drop of water should skitter and evaporate immediately, not just bubble. Pat the meat completely dry, season generously with salt and pepper, then place it in the pan without moving it.

Don’t touch it for at least 2–3 minutes. The meat will release naturally from the surface when a crust has formed; if it sticks, it’s not ready to flip. Sear the second side, then transfer the whole pan to a hot oven (230°C / 450°F) to finish cooking through. This method — hob sear, oven finish — consistently produces the best results for steaks, chicken thighs, and pork chops.

Oven Use

Cast iron is one of the very few pan types that can go from hob to oven at any temperature with no issues. It has no plastic or silicone components, no risk of warping, and no coating that degrades at high heat. This makes it ideal for frittatas, shakshuka, skillet breads and cornbread, and anything else that starts on the hob and needs to finish in the oven.

Preheat the pan on the hob first, then add ingredients and slide straight into the oven. Always remember: the handle stays hot long after the pan comes out. A folded tea towel over the handle is a good visual reminder.

Deep Frying and Shallow Frying

Cast iron’s high heat retention makes it excellent for shallow frying — the oil temperature drops less when food goes in, which means better browning and less greasy results. Fill the pan no more than halfway with oil to avoid overflow when adding food. Use a thermometer to check oil temperature before adding anything, and don’t crowd the pan. For full deep frying, a dutch oven shape is more practical than a skillet — see my best cast iron dutch oven guide for suitable picks.

Baking

Skillet cornbread is one of the simplest things you can bake in cast iron, and one of the best. Pour the batter into a preheated, lightly oiled skillet and bake at 220°C / 425°F for 20–25 minutes. The bottom and sides develop a golden, slightly crispy crust from direct contact with the hot iron — something you can’t achieve in a regular baking tin. The same principle applies to skillet cookies, single-serve cakes, and focaccia.

Cooking Eggs

Eggs in cast iron have a reputation for sticking, which puts some people off. It’s a technique problem, not a pan problem. Preheat the pan properly (2–3 minutes over low-medium heat), add a generous amount of butter, let the butter foam and subside, then add the eggs over a slightly lower heat.

The protein needs to set quickly, but not so fast that the egg seizes and sticks. A well-seasoned pan makes eggs considerably easier; a newer pan may need more butter or oil to compensate. With practice, this becomes as natural as any other cooking method.
