Roasted Beets?

tuckatodd

I make roasted beets pretty often at work.  My question here compared to the chef steps approach is that mine take forever.  I usually wrap 3 or 4 in foil with some oil and sometimes a little water for steaming.  Place them in a hotel pan on a bed of kosher salt, (my chef's idea).  They usually take any where from 2 to 2.5 hours? We do not have a combi oven so this could be the difference as you can use steam with them.  Thoughts anyone or any pointers.  Thanks!!
