Method

Let roast stand at room temperature for 1 hour. Meanwhile, preheat the oven to 450°F.

Place roast, rib side down, on a rack set in a roasting pan and rub all over with salt, pepper and rosemary.

Roast for 30 minutes, then lower oven temperature to 375°F.

Continue to roast until an instant-read thermometer inserted into the thickest part of roast, without touching bone, reads 125°F for medium-rare, about 1 1/2 hours more. Let rest for 30 minutes before slicing.

About 30 minutes before roast is done, brush onions all over with oil and arrange on a large rimmed baking sheet.

Place in the oven with roast. When roast is done, increase oven temperature to broil, move onions to a higher rack, and broil until tops are slightly charred and caramelized, about 5 minutes.

Slice roast, arrange on a platter with onions and serve.
