I've done beets and potatoes in the slow cooker, so why not garlic? It may not be exactly the same as roasting in the oven, but it beats heating up the kitchen!
Tear pieces of foil large enough to completely enclose each head of garlic.
Wrap each head of garlic tightly in foil.
Place garlic inside your slow cooker, cover and cook on low for 6 hours.
Remove from foil packets, cut in half crosswise and squeeze out the roasted garlic pulp.
