This cozy dinner for two is easily assembled for a fall or winter weeknight meal. Although you can simply cut your parsnips into 3/4-inch (2-cm) lengths, our test kitchen cooks like to employ the roll cut (also known as oblique cut) technique, which creates attractive pieces with plenty of surface area, which promotes quick cooking. To do this, starting at the narrow end of the parsnip, make a diagonal cut holding your knife at a 45-degree angle. Rotate the parsnip a quarter turn, cut again at the same angle and repeat as needed.
