Pat the turkey dry all over with paper towels. Slather with the Rub, using most for the side and top.

Place the garlic, onion and thyme face down in the slow cooker. Place the turkey breast on top so it is elevated.

Slow Cook on LOW for 6 hours (do not use high) or until internal temperature reads 165F/75C when thermometer is inserted into the middle. Check internal temperature at 5 hours if you can.

Remove turkey from the slow cooker (do not leave in slow cooker on Warm setting) and let it rest for 20 minutes before crisping the skin.

Preheat grill/broiler to high. Place an oven shelf 30cm / 1 foot from the heat source. Remove turkey breast from the slow cooker into a heatproof serving dish. Place on the oven shelf and broil for 3 to 5 minutes until the skin is crispy. Keep an eye on it - it browns very quickly!

Strain the liquid into a measuring jug, squishing the garlic etc to extract all the flavour. If you are short of 2 cups, top up with chicken broth (I usually get 2 cups of liquid from a 4 lb / 2 kg turkey breast).

Melt butter in a saucepan over medium heat. Add flour and mix to combine. Pour about 1/2 cup of liquid into the flour mixture and mix until it forms a paste. Slowly add remaining liquid, stirring as your go. Use a whisk if required to make the gravy smooth. Simmer until thickened - take it off before it is as thick as you want because it will continue to thicken.
