Settle an argument for me. Do you do this...

[PinkBalloon123]

When cooking frozen food, chips or a birds eye breaded chicken etc. I just whack it in the oven for half an hour job done. But...

do you heat the oven up first?

Depends if I'm in a hurry or not

I never used to. Dh does religiously. If he is in the kitchen I do so too, but not if I'm on my own. Zero difference in food outcome.

I don't heat the oven up first, I just add on an extra few minutes to make sure everything's cooked properly.

I allow an extra 5 minutes on the cooking time for a cold start.
I sometimes warm the oven, if I remember, but modern ovens warm quickly so it doesn't make much difference really.

Always heat oven up and wait for oven temp light to go off and then add food to be cooked.
Have read somewhere it doesn't make a difference with modern ovens anymore.

I always warm oven for at least 10 mins before putting anything in! My DM thinks I'm ridiculous and refuses to.

I always heat the oven first. I assumed that the instructions that say heat the oven to... means without the food in it

Yes I always pre- heat the oven. I worry I might make the kids ill if it doesn't heat through properly. My Dh also doesn't agree with me.

I click the oven on while putting stuff on to trays and setting the table. I find the result better from full heat.

Eh yes. I don't expect an oven to instant each 180 degrees or 220 degrees. I leave a few minutes for it to reach the optimum temperature and then whack the food in.

My oven has a rapid heat function so doesn’t take long so no-unless I’m baking cakes

Yes, I always preheat the oven.

No I've never pre heated an oven.

No - generally just chuck it in when I turn the oven on.

My oven takes 20 minutes at least to get to temperature, so I do now, I didn’t before though.

I don't. DH does.
He has no confidence in the kitchen so follows the instructions on the box, if it says preheat the oven then he will. I know when this matters and when it doesn't.

I don't preheat oven (because as one tends to it well in advance, it means it's on for longer and that's wasteful)

I add a bit to the cooking time.

Depends if I'm in a rush or not

If I don't properly warm the oven first I will add a minute or two to the timer though to ensure its cooked through

Yeah I do but only 5 mins or so

I have a gas oven - it gets to temp so quickly, you don't need to preheat. My electric oven takes 10 mins to get to temp, so I do preheat that one.

Yes always.

No, never for frozen food. I just give it an extra 5 minutes or so from the instructions on the packet.

No, but I cook on gas - it's a lot quicker to heat than electric

No.

My oven is shit, seems to cook much better when I reheat it
