Instructions

Step 1: Preheat your oven to 300°F (150°C). In a small bowl, combine 6 tbsp softened unsalted butter with 2 tbsp finely chopped fresh sage leaves, 1 tbsp orange zest, 1 tbsp lemon zest, and 4 minced garlic cloves. Mix thoroughly until well blended.
Step 2: Pat dry the 3 lbs boneless turkey breast with paper towels. Rub the turkey all over with 1.5 tsp salt, 1 tsp black pepper, and 2 tbsp olive oil, then spread the prepared sage and citrus butter evenly under and over the skin, massaging it in.
Step 3: Place the turkey breast on a rack inside a roasting pan. Roast in the preheated oven for about 2.5 to 3 hours or until an internal temperature of 165°F (74°C) is reached and the skin is golden and fragrant.
Step 4: Remove the turkey from the oven and let it rest for 15 minutes before slicing to allow the juices to redistribute, resulting in moist, flavorful meat.
