Rub meat all over with herb paste. Cover; chill at least 3 hours. (Can be made 1 day ahead. Keep refrigerated.) Preheat oven to 450°F. Place meat, fat side up, on rack in roasting pan. Roast meat 15 minutes. Reduce oven temperature to 350°F.

Remove from oven; let stand 20 minutes. Cut crosswise into 1/3-inch-thick slices. Arrange slices on platter.
