Question: are all tefal pans oven safe?
Answer: Nonstick linings are safe up to 260C/500F, which is as high as any home oven gets. The limiting factor in pots and pans is the handle: Tefal uses Bakelite on some of its pans, and that can't be heated over 350F or it will be damaged. ... If you are going to use teflon in an oven you should remember to preheat the oven.
