Discard foil. Brush ham with 1/3 of the glaze. Bake, uncovered, 1 hour or until heated through (140ºF), brushing with remaining glaze every 20 min. Meanwhile, toss parsnips and carrots with oil in large shallow pan. Add to oven with ham the last 45 min. of the ham baking time, turning vegetables every time ham is brushed with glaze.
