01 - Preheat the oven to 350°F.
02 - Pat the turkey breast dry with paper towels. Carefully loosen the skin and layer the ham slices evenly beneath the skin, covering the breast.
03 - Rub the turkey breast with olive oil and season with salt and black pepper.
04 - Place the onion, garlic, thyme, and rosemary in the bottom of a roasting pan. Set the prepared turkey breast on top, skin-side up.
05 - In a small bowl, mix together honey, Dijon mustard, brown sugar, and apple cider vinegar to make the glaze.
06 - Brush half the glaze over the turkey breast.
07 - Pour chicken broth into the roasting pan.
08 - Roast for 1 hour. Baste the turkey with pan juices and brush with remaining glaze.
09 - Continue roasting for another 30 minutes, or until the internal temperature reaches 165°F and the skin is golden brown.
10 - Remove from the oven, tent loosely with foil, and let rest for 15 minutes before slicing.
