I had a small pork shoulder in the freezer, 4 pounds, and decided to roast it today. I found this recipe on Bon Appetit. Slow-Roasted Pork Shoulder with Mustard and Sage. The result was over the top good. I even served it with a soft polenta. The meat was so tender and so full of flavor.
skinless, bone-in pork shoulder (Boston butt; 5–6 lb.)
Kosher salt and freshly ground black pepper
½ cup Dijon mustard
¼ cup finely chopped fresh sage
2 tablespoons finely chopped fresh marjoram
4 cloves garlic finely chopped
Place a rack in lower third of oven; preheat to 325°. Season pork with salt and pepper. Mix mustard, sage, marjoram, and garlic in a small bowl. Spread all over pork, working it into all the crevices.
Place pork, fat side up, on a rack set inside a roasting pan and roast, basting with pan juices about every hour and tenting with foil if pork browns too quickly, until pork is well browned and very tender, 5–6 hours (depending on size of pork shoulder).
Let pork rest at least 10 minutes before serving (the meat should pull apart easily).
