I’m sure I’m not the first person to ask this but I can’t find anything in search (have also Googled and can’t find an answer).
We go to church on Sunday mornings and are out of the house from about 10am till nearly 1pm. We cook our main meal when we get home but if it’s a roast (especially chicken) it can be about 3.30pm by the time we sit down. A friend told me they always put a roast in before leaving the house and set the oven to come on later, leaving them time to get veg etc sorted when they get home but without eating too late. I said I thought this sounded a bit dangerous because of the time at room temperature and then the oven gradually heating up, but she says it’s fine (and also their oven only takes 5 minutes to preheat, mine’s more like 20).
If I was going to do this I’d probably want to put it in at about 10ish, then have the oven come on at about 12. So 2 hours at room temp and then 15-20 minutes before it gets to its cooking temp. Is that safe? Is it more safe for eg beef than chicken?
