How long to bake a 3.78 pound frozen pork loin roast?

Answer 1

From personal experience, the best way to bake a frozen pork roast is to seal it well in tin foil with a bit of added water and bake at 200 to 250 degrees F for up to 4 hours or more. Just wrap it, put in the oven and leave it for 4 hours. After 4 hours, check it for doneness. You are looking for juiciness and tenderness. The meat cooks slowly in its own juices and becomes fall-apart tender. If it isn't as tender as you'd like, as the defrosting will require a while, re-wrap and bake it longer.

Answer 2

1 3/4 to 2 1/2 hours.

For pork it is typically 20-25 minutes per pound at 350°F (177°C), from fresh or thawed meat to fully cooked. Always check the internal temperature to make sure it is cooked thoroughly. For pork it should be 165-170 °F (74-78°C), or warmer.

For a frozen roast it needs to thaw first before cooking, it requires an additional 10 minutes per pound to thaw the meat. The best way to do this is in a covered roaster. (Even better is to thaw it before you start cooking).
