Prepare the marinade by mixing all of the ingredients together in a large bowl or a plastic Ziplock bag. Add the turkey breast and make sure that every part is covered with the marinade. If using a Ziplock bag, expel as much air as possible before sealing it. Marinate in a fridge for 12-24 hours. If marinating is not an option, roast the breast immediately and serve with those delicious pan juices - it will still be awesome.

Preheat oven to 325F.

Place the turkey breast into a deep baking dish and pour in the marinade. It's best to use a baking dish that is not too big otherwise too much liquid will evaporate. Bake uncovered on middle rack for about 1 to 1 1/2 hours, depending on size, until the internal temperature of the meat in the thickest part reaches 160F - the temperature will rise to 165F during resting (see Notes). Baste the top and the sides of the breast with pan juices about every 20 minutes - this will prevent the top from drying out and will help with browning.

If toward the end of baking the skin did not brown enough, turn on the broiler on high for 2-3 minutes. Do this before the internal temperature reaches 160F. I normally do it at about 150F internal. Monitor broiling process very closely as the skin can go from a nice deep-golden brown to charred pretty quickly.

Remove the turkey breast from the oven and let it rest for 5 minutes before carving and serving. I find that it's best to transfer the breast to a serving platter immediately upon removing from the oven. If left to rest in the hot baking dish, the internal temperature will rise too much and meat will lose more moisture.

Carve the meat, place on a serving platter and garnish with fresh rosemary twigs. Serve with the pan juices (don't forget to discard the cooked rosemary twigs), they are out-of-this-world delicious.
