If I'm cooking double a recipe, to I need to cook it for longer?

[AskerOfStupidQuestions]

That's it really. Chicken casserole is in oven and I'm unsure of whether it needs to be in there for longer than the recipe states as I've made double.

I'd say a bit longer, but not double. Maybe test after an extra 10 mins and see how chicken is.

Ok, thanks!

also will depend on the shape of your dish. A wider shallower dish will need less extra time than a deep one
