this has been the recipe for crock pot turkey breast i have liked the best so far, after having tried a few over the past few thanksgivings. from recipetineats.com
ingredients
- 2 kg / 4 lb turkey breast, skin on, bone in or boneless (if using frozen, thaw it) (Note 1)
 - 1 head of garlic, cut in half horizontally
 - 1 onion (brown, yellow or white), unpeeled, cut in half
 - 5 sprigs of thyme (or 2 tsp dried thyme leaves)
 
Rub
- 1 1/2 tsp garlic powder
 - 1 1/2 tsp onion powder
 - 1 tsp paprika
 - 2 tsp salt
 - 5 grinds of black pepper
 - 1 1/2 – 2 tbsp olive oil
 
- Place Rub ingredients in a bowl and mix to combine, it should be a wet paste.
 - 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. (To roast, follow this recipe).
 - 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.
 
Crisp the Skin
- Preheat gril/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!
 - Serve immediately with gravy on the side.
