How to make crock pot turkey breast?
Compound butter. This is a fancy way of saying a flavored butter. Massage the butter into the skin and dot it all over the turkey breast.
Aromatics. Make a bed of arromatics (shallots, ginger, garlic) that will add extra flavor to the turkey and gravy.
Slow cook. Cook on low for 5 to 6 hours.

Finish in the oven. Give the turkey breast a brief blast in the oven to crisp up the skin. This is totally optional.

Make gravy. Use the drippings in the crock pot to make an insanely flavorful gravy.

Ingredients
You’ll need a turkey breast roast and some umami forward ingredients: butter, soy sauce, garlic powder, fresh garlic, ginger powder, fresh ginger, shallots, and chicken stock. A combination of fresh and powered ginger and garlic gives a double whammy – the powder is rubbed with soy sauce directly onto the turkey and the fresh is used to season the stock for the gravy.
