Care and technique
Uncoated steel rewards a little technique, and the technique is quick to learn. These cover it:
Buying and returns
SEIDO Cookware sells through Amazon, so your order, delivery and returns are handled under Amazon’s own policy — including their returns window. We do not take payment on this site, which is also why you will not find a price here: Amazon’s is the one that counts.
Our 5-Year Limited Warranty applies whichever UK retailer you bought it from.
The material
Nothing applied on top.
The cooking surface is 304 (18/8) stainless steel — bare steel, made without intentionally added PFAS. There is no coating to scratch, flake or wear out, because there is no coating.

Performance
Sear on the hob. Finish in the oven.
Uncoated steel takes the hob heat that real searing demands, builds the browned fond that turns a pan into a sauce — then goes straight into the oven, because there is no coating to protect. A coated pan’s heat limits can rule out one or both.

What is a 28 cm frying pan good for?
A 28 cm stainless steel frying pan earns its place when you cook for more than two. The extra surface is not about size for its own sake — it is about browning. Proteins brown properly only when they have space around them; crowd a smaller pan and moisture pools, the pan temperature drops and food steams instead of searing.
As a large stainless steel frying pan, it also covers one-pan cooking: complete dinners, hash, shakshuka for the table, rice dishes finished in the pan. And it suits meal prep — cook a full 450 g (1 lb) of minced beef or a week's worth of vegetables in one round instead of two.
- Four chicken breasts or two large steaks with browning space between them
- Family stir-fries and one-pan dinners for three to five servings
- Batch cooking and weekly meal prep in fewer rounds
- Weekend breakfasts — bacon, eggs and hash browns without juggling batches
Is this a 30 cm frying pan?
No — and we won't round up. This frying pan measures 28 cm (11 in) across the rim. If a recipe or a habit calls specifically for a 30 cm pan, this one is 2 cm narrower.
In practice, 2 cm on paper matters less than how the pan fits your hob — measure your hob rings before you decide. If you need the most cooking space above everything else, a 30 cm pan gives you slightly more. For family cooking, 28 cm is a practical sweet spot.
Why uncoated stainless steel?
The cooking surface is bare 304 (18/8) stainless steel. There is no coating — so there is nothing to flake into food and no coating to wear out.
SEIDO Cookware frying pans are made without intentionally added PFAS and without synthetic coatings. What you get instead is a surface that rewards heat: bare stainless steel builds fond — the browned layer that becomes the base of a pan sauce — which coated surfaces are designed to prevent.
Uncoated steel asks for one habit: preheat before you add oil. Give the pan two to three minutes on a medium heat, test with a drop of water, then cook. It is a simple habit to pick up, and it stays with you.
How does the 28 cm fit the SEIDO Cookware frying pan range?
SEIDO Cookware makes three frying pans, all tri-ply clad with an uncoated 304 (18/8) cooking surface: 20 cm (8 in), 24 cm (9.5 in) and 28 cm (11 in). The 20 cm handles eggs and single portions. The 24 cm is the everyday middle. The 28 cm is the family-size frying pan — the one you reach for when the table is full.
If your kitchen has room for one large frying pan, this is the size that earns it. Buy now on Amazon.

Frequently asked questions
How many servings can a 28 cm frying pan handle?
A 28 cm (11 in) frying pan comfortably cooks three to five servings. In practice that means four chicken breasts with browning space between them, two large steaks side by side, a full 450 g (1 lb) of minced beef or a stir-fry for a family of four. For single portions or a couple of eggs, a smaller frying pan is the more practical fit.
Is a bigger frying pan harder to heat evenly?
A larger pan asks more of your hob, so technique matters. Preheat the empty pan on a medium heat for two to three minutes on your largest hob ring — not a small one, which leaves the edges lagging. Test with a drop of water: when it beads and rolls across the surface, the whole pan is ready. Add oil, then food. Rushing the preheat, not the pan size, is what causes uneven results.
Does the 28 cm frying pan have a non-stick coating?
No. The cooking surface is uncoated 304 (18/8) stainless steel — there is no coating to scratch, flake or wear out. SEIDO Cookware frying pans are made without intentionally added PFAS and without synthetic coatings. For easy release, preheat the pan fully, add oil and let proteins brown before turning; they release on their own once a crust forms.
What warranty comes with the 28 cm frying pan?
Every SEIDO Cookware frying pan, including the 28 cm (11 in), carries a 5-Year Limited Warranty and is sold in the UK on Amazon.co.uk. If you are comparing large stainless steel frying pans, check the warranty term alongside the construction — this frying pan is tri-ply clad, with a 304 (18/8) cooking surface.
