Oven – I left the non-stick pan in the oven while it was preheating, can I still use it

I would suggest the easiest way to cook ground beef with only disposable items is a grill. It's worked great for more than a couple of years.

But... If you don't have that, there are a few other things you can do.

Labor intensive but extremely effective is the raised rack made out of foil. You construct a tray out of tinfoil and add ridges to the bottom every inch to an inch and a half. This will cook your beef and allow grease runoff so you meat doesn't just cook in it's own fat.

The only other thing I could think of would be to cover one of your burners completely with tinfoil and use it like a frying pan, but i'm prertty sure that's gonna result in a lot of cleaning time, so it would probably be a negative once you took it all together.

I tried seasoning an aluminium kawali and was pretty successful doing this. I cleaned it very well and then layered it with a bit of oil (use peanut or canola) and then baked it outside on the bbq (or oven) for 30mins each time and then reapplying oil when it’s cooled down to touch. Important and ensure your kawali is upside down when baking and remove any handles. I repeated these steps 5 times ( see pics attached for result). Before using the wok properly, I sacrificed onions and ginger and burnt it for seasoning and then did the same thing with chicken pieces. To clean I used warm water, wipe it paper towel and dry it on stove top to fully dry the kawali. I then, apply some oil on it before storing on paper bag until next use.
