Question: how long to cook a frozen 3 lb pork roast?
Answer: Wrap the roast completely in foil, place in a baking pan and roast at 325º for 3–4 hours. Let it cool, and you can slice or shred it to make carnitas, BBQ pulled pork, etc. Make a pan gravy with the drippings. you can refreeze portions in baggies to microwave when you need it.
