I have a set of saucepas. I recalls from when I got them that the silicon handle is oven safe, so that you could put them under the grill to finish. But I don't recall if the glass lid is also oven-safe. Its handle is also silicon, but that might just be to match
I am considering if I could use it to cook bread in the oven, as the particular bread I am using calls to be cooked in something with a lid, e.g. a cassarole dish, and my dutch oven is too large.
