Hello!
I have done some experiments with this too, (Im from the UK so everything will be Oc not Of, sorry to confuse!)
So my first oven roast experiment i ended up with a fairly dark roast by accident but it also held a diffrent taste profile to how it would have if i had done a normal dark roast with the same beans, this expriment was not exactly a slow roast but got me thinking about it more;
Pre heat electric fan oven to 180oc,
place beans in a colander on middle shelf,
first crack began around 10 mins into the roast.
Its also good to give the beans a little shake every 5 mins or so to keep an even roast and dispurse chaff.
PS. Oven gloves are essential!
Another experiment I tried after was a real slow roasting in the oven,
Same principles only this time i set the oven to 75oc.
It took about an hour and half for first crack to appear and then i kept roasting for another 40 mins.
The end result was just what you would expect from a medium roast bean.
Overall, as far as a taste difference goes i havent found any pros to roasting in an oven compared to my normal roast.
But it is fun
