Fire up your Cru oven.
In a small bowl, mix the herb butter ingredients. Spread the herb butter underneath the turkey's skin. Place turkey breast in a cast iron pan.
Make sure your Cru oven has cooled down to abut 600°F.
Cook the turkey in your Cru oven, making sure to rotate every 10-15 minutes. It should take about an hour and a half - turkey breast is cooked at 170°F. If the turkey is browning too quickly, cover with foil and continue cooking.
