Healthier ceramic, cast iron, glass, and stainless steel bakeware, plus the best of the “ceramic” non-stick options. If you have questions about lead, steel, nickel, non-stick coatings, or Prop 65 warnings, read my Metal Guide, Coatings Guide, and Part 2 of my course for satisfying answers.
Stainless Steel
Glass
French PYREX (uppercase!) is made from 100% borosilicate, which is a combination of boron and silica— boron is in many nutritional supplements and silica is the main mineral glass is made of. It is more resistant to heat changes than American Pyrex. This brand is ideal if you want to stick with glass for thinner bakeware like cookie sheets. Imported into the US from France by a woman dedicated to safer glass bakeware.
Glass is the healthiest material for baking and cooking. As long as you don’t subject it to wild temperature changes (freezer to oven or sudden hot water), standard Pyrex is as non-toxic as you can get in the kitchen. It’s boring, but coating-free, and made with simple minerals that are heated into a liquid and formed into bakeware shapes. This is what I use when I need a baking dish.
Stainless steel is another great and non-toxic option for baking, because stainless is super healthy, as long as you don’t have an allergy to nickel or chromium. You get less from baking or cooking in a stainless pot than from eating food or taking a multivitamin (read more in my Metal Guide.) Misen’s 100% stainless steel roasting pan has edges and handles and it can be used as a sheet pan, roasting pan, or even as a griddle. Doesn’t warp, and is an internet favorite. No coatings. A healthy and versatile choice.
360 Cookware has an entire bakeware line, too. They’re best known for their all-stainless slow cooker, but they also have classic cookie sheets, cake pans, loaf pans, and even cookie cutters. Made with 316 steel, which isn’t necessarily healthier than regular stainless, but is more durable and corrosion resistant.
Cast Iron
Ceramicware
Xtrema offers glazed ceramic bakeware for natural non-stick functionality. I consider leach-tested glaze to be second-healthiest, because it’s made from sand and mineral pigments— as opposed to say, “ceramic” non stick coatings, which are actually polymer-based and proprietary. They’ve done repeated leach testing on both their ceramic and their glaze, and meet Prop 65 requirements every time. There are no PFAS or nanomaterials present in it, which I appreciate. (If you’ve followed the Tamara Rubin/Xtrema drama, it’s ironically made this brand one of the most thoroughly tested options— you can read more about XRF, leach testing, Prop 65, and my thoughts in my guide here.) Ceramic is super heat resistant, so you can take these straight from the freezer to the oven or vice versa.
Made In’s porcelain (a type of ceramic) bakeware line is so pretty, and made from a 200 year old French ceramic recipe. The clay, sourced from Burgundy, is not glazed or coated with anything, and is inherently non-stick. They said in an email that they are lead, cadmium, and aluminum free, and have their ingredients posted, all of which are naturally occurring minerals common in ceramic clay. They have done third party testing of their clay and meet Prop 65 requirements. Ceramic is super heat resistant, so you can take these straight from the freezer to the oven or vice versa, and they look nice for serving, too.
If you’re looking for enameled cast iron bakeware, Staub is a healthy choice. I consider leach-tested enamel (or true ceramic glaze) to be second-healthiest, because these coatings are both made from sand and mineral pigments. Testing confirms heavy metal leaching is non-existent or minuscule, making enamel a pretty safe bet— as opposed to say, “ceramic” non stick coatings, which are actually polymer-based and proprietary. Staub has done third party testing and confirmed via email they meet EU and Prop 65 standards— and reassured me that they use traditional sand and pigment -based enamel (no PFAS, nanomaterials, lead, or cadmium.)
Lodge has an entire line of cast iron bakeware including muffin tins, bundt pans, and other specialty shapes, along with your standard casserole dishes, baking sheets, and loaf pans. Cast iron is super healthy, and gets better with time as you season it. Pre-seasoned with vegetable oil so it’s immediately non-stick. Start using your own favorite cooking fat with it upon arrival.
Ceramic Non-Stick
(FYI, “ceramic” non stick is not actually ceramic—you can read more in my Coatings Guide.)
In terms of material health, transparency, and testing, Our Place’s “ceramic” non stick is very similar to Caraway’s, and choosing between them would just come down to your aesthetic, their reviews, and what kinds of features you’re looking for. They also use nanomaterials in their coating, are also PFAS free, and are tested to Prop 65 standards to ensure no lead or cadmium leach. They were very patient, kind, and thorough with my many emails. Like Caraway, not perfect, but still definitely better than untested or PFAS-containing non-stick bakeware.
Listed here to thoroughly round out the millennial brands of ceramic non stick bakeware, and because I get questions about it, Great Jones is the least healthy of the bunch and in my opinion, engages in more healthwashing than Caraway and Our Place, because their statement that stays “PTFE and PFOA free” makes it seem like they’re free of forever chemicals if you don’t have the nuanced understanding that PTFE and PFOA are just 2 of thousands of types of PFAS. They are not free of all PFAS, as confirmed by email, in which they stated, “Holy Sheet, Little Sheet, Breadwinner, and Patty Cake is PFOA-free but not entirely free of PTFE or PFOS. They’ve all passed industry standard lead tests, and are free of cadmium.” Their pieces are very cute, and I appreciated their kind, honest, and prompt email responses.
I have Caraway’s “ceramic” non-stick line listed because I get a lot of questions about it, and because it’s an OK-ish option from a material health point of view. I think they do overstate the healthiness of their non-stick ceramic coating, and they did confirm via email that there are nanoparticles in it (likely nano-titanium dioxide.) However, they have done leach testing to prove that no heavy metals, titanium, or PFAS escape into your food per US and German limits for safety. They’re also PFAS free, which is definitely better than average. So, they’re imperfect, and there is some inherent risk until we learn more about nanomaterials and whether or not they’re an issue for cooking with. That said, they’re very aesthetic, and people like how they stack for small spaces.
If you want bakeware with a non-stick coating, GreenPan is the best option because they are the most transparent, thoroughly-tested, and best from a material standpoint. While no company fully discloses their ceramic non stick coating ingredients, and they’re all imperfect, GreenPan is definitely free of nanomaterials including nanotitanium, and have always been free of all PFAS. Their coating brand name is Thermolon, and it meets Prop 65 standards for lead and cadmium. They’ve also done testing to confirm that even at 850° the pans don’t release toxic fumes. While I think it’s better to bake on completely known surfaces, this is a pretty good option if you require non stick, and they’re a step above the rest in this category. Read more about coatings in my guide here, or by clicking the non-stick symbol below.

FYI ➜ “Non-toxic” doesn’t have a definition, and I use the words chemical-free, toxin, and toxic on Interior Medicine inaccurately. I do this for practical purposes, for now: they’re accessible terms that allow people to find what they’re looking for, and they’re shorthand for a complicated problem. I made an entire (free!) course about this. Check it out here.
