Step 1: Preheat your oven to 375°F (190°C). Pat the turkey breast dry with paper towels.
Step 2: Rub the turkey breast all over with olive oil, then season generously with salt and black pepper.
Step 3: Place the seasoned turkey breast, skin-side up, in a roasting pan or oven-safe dish.
Step 4: In a small saucepan, combine the cranberries, orange juice, brown sugar, honey, orange zest, grated ginger (if using), and cinnamon (if using). Bring to a simmer over medium heat, stirring occasionally, until the cranberries burst and the sauce slightly thickens, about 8-10 minutes.
Step 5: Pour about half of the cranberry orange glaze over the turkey breast.
Step 6: Roast for 45 minutes, then baste with more glaze from the pan. Continue roasting, basting every 15-20 minutes, until the internal temperature reaches 160-165°F (71-74°C) in the thickest part of the breast. Total cooking time will be approximately 1 hour 15 minutes to 1 hour 30 minutes, depending on the size of your turkey.
Step 7: Once cooked, remove the turkey breast from the oven and transfer it to a cutting board. Loosely tent with foil and let it rest for 10-15 minutes before slicing. This allows the juices to redistribute, ensuring a tender and moist turkey.
Step 8: While the turkey rests, you can gently reheat any remaining glaze in the saucepan. Slice the turkey breast against the grain and serve with the warm cranberry orange glaze.
