Is the Cosori TurboBlaze Ceramic or Teflon?

So here is the straight version, with the sources.

The short answer

Cosori currently states the TurboBlaze basket and crisper plate are PFAS-free ceramic. An independent testing lab, RTINGS, reported PTFE on the unit it tested—and its own changelog notes that Cosori later switched to ceramic. Both things are true. They describe units made at different times.

What nobody publishes is a way for you to tell which one is in the box before you open it. That is the honest gap, and it is covered further down.

What the manufacturer says

The exact model here is CAF-DC601-KUS, the 6.0-quart TurboBlaze in Dark Gray. Cosori's own product materials, checked 2026-07-26, state:

Cosori's genuine replacement parts say the same thing. The official replacement basket (CRP-DC601RB-KUS) and the official crisper tray, both sold for the CAF-DC601, are each listed as ceramic-coated and dishwasher-safe. That matters more than the marketing page: replacement parts are what the factory is shipping now.

What independent testing found

RTINGS published a hands-on test of the standard TurboBlaze (test bench updated 2026-02-20). The unit they measured reported PTFE—the material most people mean when they say Teflon. Their changelog notes Cosori subsequently moved to a ceramic coating.

Consumer Reports also has a lab entry for the exact CAF-DC601-KUS model. It does not settle the question: it records the basket only as generic “nonstick coating,” without naming ceramic or PTFE.

So the evidence lines up like this:

The part no one will tell you

There is no published way to identify which revision you are buying. We looked for one specifically: no cutoff date, no serial range, no packaging marking, and no model-number suffix that Cosori documents as a coating indicator.

You may run into a claim online that CAF-DC601 is the PTFE version and CAF-DC601-C is the ceramic one. We chased that down. It traces to a single page with no author, no citations, and no manufacturer backing, and the suffixes Cosori actually uses in the wild—-KUS for the US, -KEUR and -WEUR for Europe—behave like regional markers, not coating markers. We are not repeating that claim as fact, because it is not one.

What to actually do

If the coating is the deciding factor for you:

• Read the listing you are actually buying from. Current listings that say PFAS-free ceramic in the title or specs are describing the current revision. That is the strongest signal available to a shopper.
• Buy new, from a current listing, rather than open-box or old stock. The PTFE units are older production.
• If it matters enough, ask before you buy. A pre-purchase question to the seller about the coating on the unit they are shipping is reasonable, and their answer is worth more than any article—including this one.
• Check the replacement basket. If you ever replace it, Cosori's genuine CAF-DC601 basket is currently ceramic, so a swap resets the surface regardless of what the original was.

One more thing worth knowing

While checking this model we found a separate discrepancy worth flagging, because it affects whether this fryer fits your dinner. Two independent labs disagree on how much it actually holds. Against a 6-quart claim, RTINGS measured 6.3 quarts and Consumer Reports measured 4.5 quarts. That is a 1.8-quart spread on the same product.

We are not going to reconcile that for you, because neither lab publishes enough about its method for anyone to honestly say which figure describes the space you will actually use. Treat 6 quarts as the optimistic number, and if you regularly cook for more than three people, plan around the low end.

Where to check the current listing

Because the coating answer depends on which revision you get, the useful link is not to one fixed listing but to the exact model, so you can read what is being sold today:

• COSORI TurboBlaze CAF-DC601-KUS on Amazon: check the title and specs for PFAS-free ceramic before ordering.
• COSORI genuine replacement basket (CRP-DC601RB-KUS): currently listed as ceramic-coated and dishwasher-safe, if you want to replace the surface on a unit you already own.
