Pull the turkey breast from the fridge 30–45 minutes before cooking to take the chill off. Pat all sides completely dry with paper towels — wet skin won't brown. Mix softened butter with garlic, salt, pepper, and herbs like thyme, rosemary, and sage. Gently separate the skin from the meat to create a pocket. Spread one-third of the butter under the skin onto the meat, then coat the top of the skin and exterior with the rest. Set the breast skin-side up on a rack in a shallow roasting pan or greased casserole dish. Insert an oven-safe thermometer into the thickest part, keeping the tip away from bone.

Preheat oven to 177°C. Place turkey breast on the center rack and roast uncovered. Plan for about 20 minutes per pound — a 4- to 5-pound breast takes roughly 75 to 120 minutes. Baste every 30 minutes with pan drippings. If using a butter or wine basting mixture, brush half on after the first 30 minutes and the rest 30 minutes later. Start checking internal temperature after 1 hour. Insert a thermometer into the thickest part without touching bone. If the top browns too fast, tent loosely with foil. The breast is done at 74°C. Do not rely on color alone — always confirm with a thermometer.

在74°C时拉出火鸡，转移到砧板。静置10–15分钟后再切割——跳过这会导致汁液流出，肉类变干。温度可能会略微上升；这是正常的。 快速锅汁：从滴油中撇掉脂肪，加水至约2杯，以中火加热，搅入玉米淀粉水浓液，煮沸1分钟直到变稠。 避免：温度计接触骨头、跳过静置、忽视自制。切片并配汁食用。
