01 - Preheat the oven to 350°F. Line a roasting pan with foil and place a rack inside.
02 - Pat the turkey breast dry with paper towels. Rub olive oil over the entire surface, then evenly season with kosher salt, black pepper, garlic powder, smoked paprika, and ground mustard.
03 - Place the turkey breast skin side up on the rack within the prepared roasting pan.
04 - Combine maple syrup, Dijon mustard, apple cider vinegar, orange juice, brown sugar, cinnamon, cloves, and allspice in a small saucepan. Simmer over medium heat, stirring occasionally, until slightly thickened, about 5 minutes. Remove from heat.
05 - Brush the turkey generously with a portion of the glaze, reserving the remainder for basting.
06 - Roast the turkey for approximately 1 hour and 40 minutes. Baste with reserved glaze every 25 minutes. If browning occurs too rapidly, tent loosely with foil. Cooking is complete when an internal thermometer inserted into the thickest part reaches 160°F.
07 - Remove the turkey from the oven, cover loosely with foil, and let it rest for 15 to 20 minutes to allow the internal temperature to reach 165°F.
08 - Slice the turkey and serve with additional glaze on the side.
