Sorry I can't answer your question - I don't know if it's oven safe - but I wanted to let you know that we purchased this set about three years ago and we LOVE it. We purchased it on a whim prior to our wedding, and took the $300 All-Clad set off our gift registry. Haven't regretted it for a moment. It's a fantastic set.

FYI, we do wash these in the dishwasher and have noticed in our new stainless-interior KitchenAid DW, the black outside finish on our pots and pans is wearing off and turning a matte silver color. Don't know what that's all about, but we don't care because they don't seem to be affected functionally, and the pots & pans are stored in a drawer anyway.

It's oven-safe up to 500 degrees. Don't use it under the broiler.

I can't imagine anything you would want to put in the oven at 500 degrees for any amount of time.

The only Kirkland cookware rated in the December '05 issue is the Kirkland Signature nonstick set, which was ranked #1 in its category. Where did you see the rating of the set you bought? Thanks, and I'm glad you're enjoying it.

My husband bought me a set of these pans five years ago to replace everything non stick we had due to my parakeet being killed by the nonstick toxins.. I have really enjoyed the pans, although they are heavy.. But.. I realized fairly recently the bottom has separated on my biggest frying pan, and soon I won't be able to use it. I am going to check and see what the warranty was. I hope it was lifetime. In any event.. I would be cautious about buying them again. BTW.. I have only used these pans on gas ranges.
