Preheat oven to 350ºF.
Put butter, garlic, herbs, lemon, salt and pepper in a food processer and pulse until mixed well. Slather the turkey breast with the compound butter, making sure to get plenty under the skin. This can be done in advance, 12 hours or overnight, or 15 minutes before roasting.
Roast for 45-50 minutes, remove when internal temperature reaches 155ºF. Let rest for 15-20 minutes then slice and serve.
