help! my baking pans are bending!

does anyone know why my baking pans kind of bend in the oven? whenever i put my baking pans in the oven for any sort of cooking whether it's cookies or just using it as a base for a meatloaf pan i always hear a sudden crash and when i look inside one side of my baking pan is always tilted. It's like someone tried to bend it and got one side up and one side down. It always goes back to normal after i take it out of the oven..but i've never experienced anyone else with that problem? Could it possibly be because i store my pans in the oven even when i dont use them?

Mine Do The Same Thing And It Must Just Be That Cheap Old Alumninum!

The cheaper pans will do that.
I had a cookie sheet that did that til I invested in a better one.

thanks! i guess i have to buy new pans!

I switched to two of the large baking pans that look like jelly rolls pans. I use a silicone pad with them and the cookies bake beautifully on them. I found mine at SAMS CLUB back before Christmas 2 for $10. I had priced the smaller ones at other places for more than that for just one. I also got a couple of cake sheet pans that are good for just about everything.

I have one that's been like that for a while, but it doesn't bother me too much. I don't think I'll be upgrading till this one gets worse

This problem is endemic to thin, aluminum and non-stick (amounts to the same thing) pans.

They are heating unevenly in the oven. Because of that, different parts of the pan are expanding at different rates. This leads to a temporary warping, which cures itself when the pan cools.

If it bothers you the only solution is to invest in better grade sheet pans (or, more likely, half-sheets for the home oven). You can get them at restaurant supply places or on line. What you want is either steel or alumisteel as the material, with all steel preferred.

If you're used to non-stick pans, and switch to the steel, better invest in a silicone pad as well, or you'll experience some sticking and/or burning at first.

BTW, if you invest in standard sheet- or half-sheet pans you can also buy parchment paper already cut to fit.

This doesn't work with most housewares type pans because they are not standard sizes as used in the industry. For them you have to buy parchment paper by the role and cut it to fit.

But I Have Become Accustomed To The Popping And Buckling Noises Coming From The Innards Of Me Ole' Oven And Would Think Something Wrong If I Did Not Hear That While Baking Me Cookies!!!

Kind O' Like That Old Car I Used To Have That Made So Many Clinking, Chugging, And Churning Noises Forever, As Soon As I Changed The Oil And Did A Fine Tune On It Wouldn't Ya' Know Tha Darn Thing Back-fired Once And Gave Up The Ghost!

There's An Old Proverb; If It Aint Broke Don't Fix It, And It Aint Broke Cupcakecook!

Invest in good pans - you wont' be sorry! Ditto with cooking pans. Ditch the aluminum pans - not good for you anyway. Even if you have to buy them one at a time - it's well worth it.

i didnt think that my pan was aluminium. I have the half sheet jelly roll pans, but i dont think that they are industry size, because i do have to cut my parchment papers to fit. I bought my pan at this GREAT cooking supply shop where i live. I think it might be the only one of it's kind in southern california and they've been around FOREVER! it's called Cookin' Stuff and it's one of the those great local shops that just about everyone and their grandmother (probably especially their grandmother's) know about. They only sell everything that has to do with cooking from knives to mixers and cute accessories such as magnets and aprons! My mom and sister and I have been going there forever so i guess i'll have to go back and get better ones.

Triple C, try putting a kitchen magnet on the pan. If it's steel the magnet will stick.

But, if they're not standard sizes, I suspect they are aluminum and designed for the home market. The steel sheet- and half-sheet aren't all that expensive, actually. And they won't do that dance in the oven.
