About 350 degrees Fahrenheit For an 1 hour and1\2 to two hours.
you should roast a piece of beef at the temp of 160 deegrees This should read "TO the temp of 160 degrees, internal temp" (for medium doneness) If you roast it AT the temp of 160, it will probably spoil (or wind up full of bacteria) before it ever reaches doneness. Medium rare would be done at an internal temp of 145. Your oven temp should be at least 250 to 350 degrees depending on the size of the roast, the vessel that it is being roast in, covered or uncovered, & desired browness on the outside.
The recommended internal temperature for a roast to be considered done is 145F (63C) for medium rare, 160F (71C) for medium, and 170F (77C) for well done.
put roast in a preheated 500 degree oven for 20 minutes, then reduce heat to 325 and cook until done - use a meat thermometre and take roast out at 125 -135 and tent with foil for additional 20 minutes or so.
7 hours @ 250 for a rare roast
Roast at 325 to 350 degrees. Size of turkey will define how long to cook but the internal temp of the bird (@ breast) should be 185 degrees.
165 degrees F
To cook an arm roast in the oven, you typically need to cook it for about 2.5 to 3 hours at 325F until it reaches an internal temperature of 145F for medium-rare or 160F for medium.
To tell if a pot roast is done, use a meat thermometer to check the internal temperature. The roast should reach at least 145F for medium rare, 160F for medium, and 170F for well done. Additionally, the meat should be tender and easily pierced with a fork.
To cook a chuck roast on the grill, first season the meat with salt, pepper, and any other desired spices. Preheat the grill to medium-high heat and sear the roast on all sides. Then, move the roast to indirect heat and cook for about 1-2 hours, or until the internal temperature reaches 145F for medium-rare or 160F for medium. Let the roast rest for 10 minutes before slicing and serving.
To cook an arm roast in the oven, preheat the oven to 325F. Season the roast with salt, pepper, and any desired herbs or spices. Place the roast in a roasting pan and cook for about 2-3 hours, or until the internal temperature reaches 145F for medium-rare or 160F for medium. Let the roast rest for 10-15 minutes before slicing and serving.
Internal temp = 130°F to 140°F (55°C to 60°C) for medium rare.About 15-20 min/lb at 275 - 300 degrees Fahrenheit.Your cook time (15 lb at 250*F) will be about 5.5 hr, depending upon starting internal temp of the beef (bring it up to nearly room temp and you shorten your cook time)
The minimum cooking temperature for roast beef is 145F (63C). To ensure that the roast beef is cooked safely the internal temperature should be measured with a meat thermometer. Here is a list of recommended minimum internal temperatures for roast beef measured at the thickest part: 155F (68C) for medium-rare 160F (71C) for medium 165F (74C) for medium-well 170F (77C) for well-doneIt is important to note that the USDA recommends cooking all beef including roast beef to an internal temperature of at least 145F (63C).
