Gather the ingredients.
Make sure that the Italian seasoning is finely ground. If needed, run it through a spice grinder or a mortar and pestle.
Combine all ingredients and mix well. This marinade will settle so give it a stir when reloading the needle.
Inject the marinade into the turkey, butter the inside, and/or season the outside, if desired. Discard remaining marinade. Cook turkey per recipe instructions.
