Meanwhile, combine marmalade, orange juice, Dijon, garlic, and rosemary sprigs in a saucepan over medium heat for the glaze. Bring glaze to a boil, stirring occasionally, and cook 1 minute, then remove from heat and let cool; discard rosemary sprigs.
Remove pan from oven. Using 2 wads of paper towels, rotate turkey breast side up then brush turkey with glaze. If broth has evaporated from bottom of pan, pour in an additional ½ cup.
Return pan to oven and continue roasting turkey until an instant-read thermometer inserted into the breast, but not touching the bone, registers 160°F and inserted into the thighs, but not touching bone, register 175°, 65–75 minutes more, brushing turkey with remaining glaze every 20 minutes until all glaze is used.
(To properly temp a turkey, insert the thermometer tip deep into the meat in several places and pull it back out slowly. Watch the numbers change on the screen. If you see a number that is below 160°F in the breast, return the turkey to the oven for more cooking.)
Remove pan from oven and gently transfer turkey to a carving board and let rest, uncovered, for 30 minutes. Slice and serve with favorite gravy.
