I roast garlic bulbs in the oven frequently, but they aren't 'crispy'. The method I use is to cut a sliver off the top and bottom of the entire bulb (all cloves intact), sprinkle olive oil and sea salt over the top and bake in 350degree oven until soft.
Very yummy and great in recipes! Easy to make garlic bread with it too.
@Love2Run: I do something very similar on the pit. I just cut the top about 1/4" down, oil and salt, then leave it on the smoker until it starts get soft. It's great in a pot of mashed potatoes, melted butter for bread, on the skin of a chicken to hold rub on, etc..
