About 1 1/2 hours to 1 hour 45 at 350.
Cook at 350 degrees for about 3 hours.
1 hour and 46 minutes.
If you want medium roast, try 15 minutes a pound at 350. Test the temperature. You'll want about 145.
For 4.5 hours at 350.
At least 1.5 hours at 350 degrees. It should be fork tender.
1/2 per pound at 350 degrees
10-15 minutes a pound at 350. keep an eye on them, don't let them burn.
cook it on 325-350 for about and hour and a half
this depends on how large it is and how much it weighs.
In the oven, at 350-degrees, 30 minutes per pound. Example; 6-lb roast would take 3 hrs to cook.
I'd preheat the oven to 600 F, then put the roast in to slightly sear the outside to hold in some of the natural juices. As soon as you put the roast in, lower the temperature to 350 F and roast for approx 15 minutes per pound. That 15 minutes is not sacred, use a meat thermometer and determine when it's done by the internal temp shown.
