This pork shoulder roast, which requires a mere 20 minutes of hands-on time, makes a lovely centerpiece for any celebratory meal. Though you might find that it’s just easy enough to cook up for Sunday supper, or even on a cold, wintry weeknight. A rub of fresh sage, rosemary and chopped garlic lends the meat an earthy, aromatic flavor as it roasts altogether in the oven for upwards of three hours. So you can get this mostly make-ahead main in the oven, then spend some time leisurely finishing up on sides, salads, and even dessert. For family-style serving, put the sliced pork shoulder on a platter with a few more fresh herbs.
