Meat dish baked in a dairy pan

I cooked chicken breast (a meat dish) in sauce in a dairy pan that was not ben yomo (had not been used in the last 24 hours), inside a meat oven. The dish was in a disposable aluminum pan that was placed on top of the dairy pan. What is the status of the food, the dairy pan, and the oven? If the pan or the oven need to be kashered, how is this done?

Shalom u’vracha. 

If there was a lot of sauce, the pan must be kashered by heating it in the oven at the highest temperature for half an hour. 

If there was not much sauce, the pan is permitted bediavad (of course, it is forbidden to do this lechatchila, but after the fact it is permitted).
