Bake the ham, uncovered, at 350 for 40 minutes. This is one the “Bake” setting, not “Convection Bake”
Turn heat down to 170 if your oven can go that low. If not, set to 200.
Spoon some of the glaze that has fallen into the pan over top the ham. Cook overnight.
if your oven only goes down to 200, you may want to loosely cover the ham with tin foil. don’t seal it tightly, just kinda form it around the ham and set it on top. this will help keep it from getting too dry.
Baste the ham as soon as you wake up. Turn the temperature back up to 350 for 30 min to caramelize the glaze.
Set the oven to “Warm” and let sit the rest of the day, basting every hour or so, until it’s time to carve and serve.
