Quarter the two onions, pull the pieces apart, and lay them at the bottom of the slow cooker to create a base for the chicken rest on.
Remove any organs and rinse off the whole chicken. Pat it dry with a paper towel.
Combine all the seasonings above to make a dry rub. Season the inside cavity of the chicken as well as the entire outside. *Make sure to see my tip above about seasoning the breasts.
Place the chicken breast side down on top of the onions in the slow cooker. There is no liquid needed because the chicken will cook down in its own juices.
Put the lid on the slow cooker and cook the chicken on low for 7-8 hours.
Once the chicken is done, remove it from slow cooker and pull all the meat off the bones to enjoy as is, or use the meat in another recipe.
