Wrap ribs tightly in aluminum foil so no steam can escape.
Put wrapped ribs on a baking sheet and cook in preheated oven for five to six hours.
Once cooked, remove ribs from aluminum foil and place them on baking tray.
Increase oven temperature to 400 degrees F (204 degrees C).
Cook ribs for an additional seven to eight minutes or until outside is crispy. Be careful not to overcook ribs.
Remove from oven and let cool for a few minutes before serving.
