Crockpot (Slow Cooker) Bone In Turkey Breast

Grease the slow cooker on all sides with butter. Make compound spiced butter by mixing the softened butter with the spices, salt and pepper. Pat turkey breast dry well with paper towels. Coat the top of the turkey breast in the compound butter, using a spoon or brush. Add the onion slices and garlic to the crockpot in an even layer, and pour chicken stock over. Add the turkey breast, butter side up, to the crockpot on top of the onions. Cover and cook on low for 6-7 hours, or until a thermometer inserted into the thickest part of the breast reads 165 degrees. Optional: Broil in the oven for 5-10 minutes for crispy skin. Allow turkey breast to rest for 30 minutes to 1 hour before slicing and serving.
