I totally get the smell factor.
My grandmother would slow roast her Thanksgiving birds overnight and there was a direct conduit from the kitchen to my bedroom above. I smelled that bird cooking all night and by morning, the last think I wanted was turkey.
Thankfully, my bed now is a long way from the kitchen and I use this method frequently.
I just did pulled pork for a party. I put it in the oven at 10:00PM at 225F. Went to bed, turned the oven off at 10AM, and let it cool in it's own juices until I could shred it.
It doesn't get much better than that.
At the party, I had this person raving about the pulled pork and asked me how I did it. (see above).
"Oh!!!! That's too much work! (not at all really). Just put it in a crock pot! It's so easy!"
I said, well, you don't get the deep caramelization and flavor in the crockpot that you get in the oven. You just get boiled meat.
Again, "that's too much fuss."
I said, that must be why you liked it so much.
Smile.
