Non-Toxic Bakeware UK (2026): Baking Trays Without PTFE
Quick answer
For lower exposure to PTFE and other non-stick coatings, bake on uncoated stainless steel, vitreous enamel, hard anodised aluminium, borosilicate glass, glazed ceramic or seasoned iron. A HaWare stainless steel tray set (£23.99) or Lakeland's enamel tray (£12.99) covers everyday roasting, with Pyrex glass for lasagne and Mermaid anodised trays for even baking.

How we chose
Most supermarket baking trays are steel or aluminium with a PTFE (Teflon) non-stick coating. We looked for trays and dishes where the cooking surface is the material itself (stainless steel, anodised aluminium, glass, glazed ceramic, enamel or seasoned iron) rather than a polymer coating. For each product we read the UK listing for material, maximum temperature and care rules. None has independent migration testing, so every pick is graded "moderate": the material choice is well supported, but there is no product-level lab data.
Why avoid non-stick coatings on baking trays?
Baking trays take more abuse than pans: metal spatulas, scouring, dishwashers and high oven heat. That matters because:
- PTFE is a PFAS, a family of very persistent chemicals that ECHA says can remain in the environment for generations. EFSA's tolerable weekly intake for the PFAS that build up in the body is very low (4.4 ng/kg body weight per week), though diet and water are the main sources rather than cookware (EFSA, 2020).
- Damaged coatings shed particles. A lab study found one crack in a PTFE surface could release around 9,100 particles (Luo et al., 2022).
- Overheated PTFE gives off fumes. Medical reviews link this to temperatures above about 350 to 400°C (Shusterman, 1993). Domestic ovens rarely reach that, but grills and empty trays under a hot grill can get close.
None of this proves a coated tray used gently is harmful. It does mean uncoated materials remove a question mark and tend to last longer.
Which baking tray materials are lowest exposure?
| Material | What touches food | Watch out for |
|---|---|---|
| Stainless steel | Bare steel | Sticking; small nickel and chromium release, mainly with acidic food |
| Anodised aluminium | Hard aluminium oxide layer | Dishwashers damage it; avoid long contact with very acidic food |
| Plain aluminium | Bare aluminium | Acidic and salty foods increase aluminium migration |
| Borosilicate glass | Glass | Thermal shock; slower browning |
| Glazed ceramic or stoneware | Glaze | Lead and cadmium in poorly made glazes |
| Vitreous enamel | Glass fused to steel | Chips expose steel |
| Seasoned iron | Polymerised oil | Acidic food, rust if left wet |
| Silicone | Silicone rubber | Low-quality silicone can release volatile siloxanes |
Aluminium: EFSA set a tolerable weekly intake of 1 mg aluminium per kg body weight and noted that food contact materials, especially with acidic or salty food, can add to intake (EFSA, 2008). Anodising seals the surface, which is why we picked anodised over bare aluminium.
Stainless steel: nickel and chromium can migrate in small amounts, mostly from new items and acidic food. EFSA has assessed nickel from food and water (EFSA, 2020). If you have a nickel allergy, glass, enamel or anodised aluminium may suit you better.
Ceramics and glazes: EU rules set lead and cadmium migration limits for ceramic articles (Directive 84/500/EEC). Buying from established makers is the practical safeguard; be wary of decorative imported pottery for cooking.
All bakeware sold in the UK must also meet the general rule that it must not transfer substances into food in amounts that could endanger health (Regulation (EC) 1935/2004; SI 2012/2619).
The best non-toxic baking trays in the UK
HaWare Stainless Steel Baking Tray Set of 2: best overall
Two full-size 40 x 30cm uncoated stainless steel trays that take metal utensils and the dishwasher. Caveat: the steel grade is not stated, food sticks unless you oil the tray or use baking paper, and thinner trays can warp at high heat.
Lakeland Enamel Handled Oven Tray: budget pick
Carbon steel with a vitreous enamel finish (a layer of glass fused onto the steel), rated to 240°C and usable on the hob, including induction. Lifetime manufacturer's guarantee. Caveat: enamel can chip if dropped, and it is not non-stick.
Mermaid Hard Anodised Baking Tray: best for even baking
Made in Birmingham, this anodised aluminium tray heats quickly and evenly and is stated to be PTFE and PFOA free, with a lifetime guarantee. Caveat: hand wash only, and it needs greasing or lining until it builds a patina.
Pyrex Essentials Rectangular Glass Oven Dish: best glass dish
French-made borosilicate glass, rated by Pyrex to the EN 1183 thermal shock test. Ideal for lasagne, gratins and crumbles. Caveat: glass browns bases less well than metal and still breaks if moved from hot oven to a wet or cold surface.
Falcon 31cm Enamel Baking Dish: budget enamel dish
Classic enamelware that goes from oven to table to freezer. Caveat: Lakeland's listing does not give a maximum temperature, and chips expose steel.
Emile Henry Large Rectangular Oven Dish: best ceramic
Glazed high-resistance ceramic made in France, rated to 270°C and grill use, with a 10-year warranty. Caveat: no published lead or cadmium test results on the product page; you are relying on EU ceramics rules and the maker's reputation.
Solidteknics Iron Baking Tray: premium pick
Pressed from a single 2.5mm sheet of wrought iron and pre-seasoned with rice bran oil, so the release layer is cooked-on oil rather than a synthetic coating. Caveat: it needs seasoning care, is not for acidic bakes, and costs £110.
What about silicone baking mats and moulds?
Silicone is flexible and naturally non-stick, but quality varies. Germany's BfR recommends that silicone elastomers in food contact release no more than 0.5% volatile organic compounds (BfR Recommendation XV), and studies have found low-molecular siloxanes migrate from silicone bakeware, more so into fatty foods (Helling et al., 2009; Zhang et al., 2012). If you use silicone, choose reputable brands, and see our guide Is silicone food storage safe?.
What to avoid
- Peeling or scratched non-stick trays. Replace them.
- "Ceramic" trays without a materials list. Many are thin sol-gel coatings on aluminium, not solid ceramic.
- Decorative imported pottery for cooking, unless sold as oven-ware by a reputable brand.
- Bare aluminium for acidic dishes like tomato bakes or marinades.
- Cheap silicone moulds with a strong smell that persists after washing.
Bottom line
For everyday roasting, an uncoated stainless steel tray or an enamelled tray does the job for under £25. Bakers who want even, light heat should look at UK-made anodised aluminium. For lasagne and crumbles, borosilicate glass or glazed ceramic from an established maker is a straightforward swap. Line trays with baking paper when sticking is a problem, and you will rarely miss non-stick.
Frequently asked questions
What is the least toxic material for baking trays?
+
There is no single winner, but uncoated stainless steel, vitreous enamel, borosilicate glass and glazed ceramic from reputable makers avoid polymer coatings altogether. Hard anodised aluminium is a good option for even baking if you hand wash it. Each has trade-offs: steel and enamel stick, glass browns slowly, and seasoned iron needs care.
Is anodised aluminium bakeware a good choice?
+
Anodising converts the aluminium surface into a hard oxide layer, which reduces aluminium transfer compared with bare aluminium. EFSA notes acidic and salty foods increase aluminium migration from food contact materials, so the sealed surface helps. Avoid the dishwasher, which can damage the anodised layer, and line the tray for very acidic dishes.
Are enamel baking trays good?
+
Vitreous enamel is a layer of glass fused to steel, with no polymer coating. It tolerates metal utensils and high oven heat (Lakeland's tray is rated to 240°C). The main weakness is chipping: a chip exposes steel that can rust, so retire trays with chips on the cooking surface.
Do stainless steel baking trays leach metals?
+
Small amounts of nickel and chromium can migrate, mostly from new items and with acidic foods. EFSA has assessed nickel from food and water. For most people, levels from cookware are minor; people with a nickel allergy may prefer glass, enamel or anodised aluminium. Washing new trays well before first use is sensible.
Is silicone bakeware a good alternative?
+
Good-quality silicone is flexible and non-stick without PTFE, but studies show low-molecular siloxanes can migrate, especially into fatty foods and from new items. Germany's BfR recommends limits on volatile compounds in silicone. Choose reputable brands, wash before first use, and avoid moulds that keep a strong smell.
How do I stop food sticking without non-stick?
+
Use baking paper or a light coat of oil, preheat metal trays before adding food, and let roasted food release naturally before turning it. Anodised aluminium and seasoned iron build up a natural release layer over time. Glass and enamel dishes work best for wetter bakes like lasagne and crumbles.
