0.5 cup butter unsalted room temperature (1 stick)
Equipment
frying pan
baking sheet
oven
kitchen thermometer
Directions
Preheat oven to 425°F. Gently loosen skin from turkey breasts and rub butter under skin and all over outside of breasts; season with salt and pepper.
Scatter thyme sprigs, rosemary sprigs, and garlic over a large rimmed baking sheet and arrange turkey breasts, skin side up, on top. Roast turkey breasts, turning halfway through, until skin is crisp and golden brown and an instant-read thermometer inserted into the thickest part of breasts registers 160°F (for optimal moistness, you will want to cook the white meat of the turkey breasts to a lower internal temperature than you would if cooking a whole bird), 45–55 minutes.
Transfer turkey breasts to a platter and let rest 10 minutes before carving.
Serve turkey breasts with pan drippings alongside.
