Ingredients

Scale

Turkey and Seasoning

  • 2.5 – 3 kg / 5-6 lb single turkey breast, skin on, bone in (not brined)
  • 1/2 tsp salt
  • Black pepper, to taste
  • 1 brown onion, halved
  • 1 head of garlic, halved horizontally
  • 3 sprigs rosemary
  • 8 sprigs thyme (optional)
  • Oil, for drizzling (to crisp skin)

Garlic Herb Butter

  • 150 g / 10 tbsp unsalted butter, softened
  • 1 1/2 tsp salt
  • 1/2 tsp black pepper
  • 4 large garlic cloves, minced
  • 1 tbsp finely chopped fresh sage
  • 1 tbsp finely chopped fresh rosemary leaves
  • 1 tbsp finely chopped fresh thyme leaves
  • 1 tbsp finely chopped fresh parsley

Gravy Ingredients

  • 1/3 cup / 50 g flour
  • 1/2 tsp soy sauce (dark) or gravy colouring
  • Chicken broth/stock, for topping up (if required)


Instructions

  1. Prepare the Garlic Herb Butter: In a bowl, mix together the softened unsalted butter, salt, black pepper, minced garlic, and finely chopped fresh herbs (sage, rosemary, thyme, and parsley) until well combined.
  2. Loosen Turkey Skin: Pat the turkey breast dry. Using a small knife, carefully cut a slit on one side of the breast to separate the skin from the flesh. Gently slide an upside-down tablespoon between the flesh and the skin all around the turkey to create space for the butter.
  3. Slather Butter Under and Over Skin: Spread about two-thirds of the garlic herb butter under the loosened skin, ensuring even coverage. Spread the remaining butter all over the surface of the skin and underside of the turkey breast.
  4. Season Skin: Sprinkle the turkey skin evenly with 1/2 teaspoon salt and black pepper. At this stage, you may refrigerate the turkey covered for up to two days to marinate and deepen flavor, if preferred.
  5. Prepare Slow Cooker: Place the halved garlic head and brown onion at the bottom of a 5-liter / 5-quart slow cooker. Put the turkey breast on top, skin side facing up. Arrange the rosemary and thyme sprigs over the turkey.
  6. Slow Cook the Turkey: Cook the turkey on low for 6 hours, checking at 4 hours to monitor progress. The turkey is done when an internal thermometer inserted into the thickest part reads 75°C (165°F).
  7. Rest the Turkey: Using tongs, transfer the turkey breast to a baking tray and reserve the cooking juices. Loosely cover the turkey with foil and let it rest for 20 minutes to allow juices to redistribute.
  8. Crisp the Skin: Remove the herb sprigs from the baking tray. Drizzle the turkey skin lightly with oil (avoid butter at this stage as it burns easily). Place the tray under a high broiler or grill about 30 cm (12 inches) from the heat source. Broil for 5 to 10 minutes, watching carefully, until the skin is crispy and golden brown.
  9. Make Gravy (Optional): Use reserved cooking juices to prepare a gravy by stirring in flour and dark soy sauce, adding chicken broth or stock as needed to reach desired consistency.
  10. Serve: Slice the rested turkey breast and serve with freshly made gravy or cranberry sauce on the side.
