First, remove the turkey from the package and pat it dry. Now, in a small bowl mix the spices and herbs together with the oil.
Next, smother and rub the turkey down with this paste. Use all of it on the turkey, even the small paste pieces that fall off. Pick them up then rub them in again.
Slice up and onion then lay it across the bottom of the crockpot. Pour in 1/4 cup of water, nothing more. Place the turkey on top of the onions. Put the lid on the crockpot then turn on low and cook for 4-5 hours. Do not cook try to cook on high.
Check around the 3 hour mark with a meat thermometer and judge how much time left you need. For a 3 pound turkey, mines was ready right at the 4 hour mark.
When ready turn the crockpot off. Cut the twine or the net from the turkey carefully. Allow the meat to rest for 15-20 minutes before serving.
