Preheat your oven to 300°F (150°C).
Score the skin of the pork belly in a crisscross pattern.
Rub salt and pepper generously over the meat and skin.
Place the pork belly in a roasting pan, skin side up.
Roast in the oven for 2 hours to render the fat.
Increase the temperature to 450°F (230°C) for the last 30 minutes to crisp the skin.
Baste the pork belly with its own fat halfway through cooking.
Let the pork belly rest for 15 minutes after cooking.
Slice into pieces and serve with your favorite sauce.
Enjoy your perfectly cooked pork belly!
