Roasting by time is an extremely unreliable method. Buy a meat thermometer (about $5) and cook pork to an internal temp of 160oF
until you get a temp at the gone of at least 170
approximately 20 minutes per pound, and internal temp of 170 degrees
Why would you "cook" a pork roast in the microwave. Pork roast are a tough meat and it requires low temp at about 10 hours like in a crock pot.
its cooked when its internal temp hits 160 degrees
you cook boneless pork chops in the over on 350 for the temp and for about 35-40 minutes.
Cook your lion of pork for 20min per kg then 20min at the end and leave to rest out of the oven for 10min coverd with tin foil then carve.Enjoy!
You cook a roast normally by the meat's internal temp., not by time. In a beef roast, the internal temp needs to be about 145 for rare, 150 for medium, and 160 for well done. And in pork roasts, it needs to be at least 160 degrees F. for medium, and 170 degrees for well done. I usually cook my roasts in an oven that is set to 325 degrees F. (Source, USDA)
using a cooking thermometer ,plunge it the roast at the thickest part. 165 degrees is the temp for pork
Until it is done (145 degrees internal temp)
i say cook@ 400 for ten minutes then turn down to 325 and cook until internal temp is 165 -170 degrees.
40 mins and 20c
185 degrees F (85 degrees C) for a fully cooked pork roast.
400 degrees F for 30 minutes.
350 degrees for two and a half hours.
7 hours @ 250 for a rare roast
The center of the cut of pork should be 160 degrees Fahrenheit.
That sounds a bit low. I roast mine at 350 deg. and it takes about 45 min. per pound to cook. What's important is the final temp. inside the roast. You need to get an oven thermometer that you can stick into the roast and check to see if it reads at least 170 deg. If not keep cooking. The lower temp. you cook at means it will take longer to reach 170 deg. inside.
Bake at 350 degrees for 30 to 45 minutes.
Preheat your oven to 450, put in the roast and immediately turn it down to 350. Cook for 30 to 35 minutes a pound -- 4 to 4 1/2 hours for your roast.
Pork should not necessarily be cooked according to "time". It should be cooked to 160 degrees at the center of the roast. One important note is that it should also be cooked at a relatively low temp. Approx. 325 degree oven. High temps can cook the outer portion of the roast too quickly & dry it out and the center may not be cooked to optimal temperature making it dangerous too eat.
I assume it is a bone in roast - For bone in 20 minutes per pound should do it. Pork should reach an internal temp of 165 degrees Fahrenheit. CHECK the link I added.
