Combine the ghee with the dried herbs, salt and pepper and set side.
Lightly grease the slow cooker with an avocado oil spray and add the orange slices, garlic and shallots to the bottom. Bundle the fresh herbs with cooking twine and place it at the bottom of the slow cooker.
Pat the turkey breast dry and add it to the slow cooker. Carefully seperate the skin from the top off the turkey breast and spread about half of the ghee mixture under the skin, and the other half on top.
Add 1 tbsp of mustard under the skin, and the other 1 tbsp on top of the skin, spreading evenly. Pour the maple syrup over the top of the skin.
Place the lid on the slow cooker and cook on low for 5-6 hours, or on high for 3-4 hours. The time will vary depending on the size, so be sure to check with an internal thermometor for 165 F!
Once fully cooked, turn the broiler on in the oven. Carefully transfer the turkey breast to a baking dish and place under the broiler for 2-3 minutes, or just enough time to get the skin lightly crisp!
Allow to rest for 10 minutes before slicing the turkey breast and serving traditional sides like green beans and sweet potatoes!
