1-First step: get the turkey ready Remove the turkey breast from the fridge 45 minutes before cooking. This helps it roast more evenly, so the outside does not overcook before the center is done. While it sits, gather your ingredients, smash the garlic cloves, and chop the herbs for the butter mixture. If your turkey is frozen, thaw it safely first in the refrigerator or using the cold water method, never in a microwave.

2-Second step: heat the oven and prepare the baking dish Preheat the oven to 200°C (390°F), then set a rack in the lower middle position. Place the 12 smashed garlic cloves and the fresh rosemary, sage, and thyme sprigs in the center of a baking dish. This herb bed will flavor the drippings and make the pan smell incredible while the turkey roasts.

3-Third step: mix the garlic herb butter In a bowl, mix together the softened butter, 1 1/4 teaspoons table salt or 1 1/2 teaspoons kosher salt, 1/2 teaspoon black pepper, minced garlic, chopped sage, chopped rosemary, thyme leaves, and parsley. Stir until everything is evenly combined. This garlic herb butter is what makes the turkey breast rich, moist, and deeply seasoned.

4-Fourth step: loosen the skin Place the turkey breast skin side up on a board or tray. Using the back of an upside-down teaspoon, carefully loosen the skin from the flesh, working slowly so you do not tear it. This little trick gives you space to slide butter directly onto the meat, which is one of the best ways to keep a roasted turkey breast juicy.

5-Fifth step: butter the meat under the skin Smear about two-thirds of the butter mixture under the skin on the top half of the breast using your hands. This part may feel a little messy, but that is part of the fun. Turn the turkey upside down and spread the remaining butter on the undersurface, reserving about 2 tablespoons for the skin. The goal is to season the meat from the inside out.

6-Sixth step: set the turkey over the herbs Place the turkey on top of the herbs in the baking dish, skin side up. Smear the reserved butter lightly over the skin. Then sprinkle the top and sides with the remaining 1/2 teaspoon salt and black pepper to taste. If your butter mixture is salted and your turkey is not brined, this balance works beautifully.

7-Seventh step: roast and baste Put the turkey in the oven and immediately reduce the heat to 180°C (350°F). Roast for about 1 hour 30 minutes, which is roughly 15 minutes per 500g or 1 lb of turkey. Baste every 30 minutes with the pan juices. For the deepest flavor and moisture, aim to baste 8 to 10 times total if your roasting time allows it. If the skin starts browning too quickly, cover loosely with foil.

8-Eighth step: check doneness the right way Use a meat thermometer and check the thickest part of the breast, avoiding bone. You want the temperature to reach 74°C (165°F). This is the safest and juiciest finish point. If the turkey is not there yet, keep roasting and check again after a few minutes. A thermometer takes the guesswork out, and honestly, it saves dinner drama.

9-Ninth step: rest before carving When the turkey reaches temperature, move it to a plate or cutting board and cover it loosely with foil. Rest for 15 to 20 minutes before carving. This helps the juices settle back into the meat instead of running all over the board the second you slice it. Resting is a small step with a big payoff.

10-Tenth step: make the pan sauce and carve Remove the herbs and garlic from the pan. Squeeze the roasted garlic cloves to release their soft centers, then pour the pan sauce into a jug for serving. Slice the turkey breast thinly, making sure each piece includes some skin or underside for the best flavor. Serve with the pan juices, or turn those drippings into a quick gravy if you like.
