If meat isn't cooked long enough, harmful bacteria can live in it and get you sick.
It is the healthiest if it is cooked to an internal temperature of 160°F. Although the cooking time can be adjusted depending on how a person likes their burger (medium rare, medium well, well done, etc.).
The temperature to cook steak to for desired doneness is typically 130F (54C) for medium-rare, 140F (60C) for medium, and 160F (71C) for well-done.
this depends on taste and cooking appliances. for instance on a bar-BQ you can cook in rare, medium, or well done, the same goes for a gas or electric stove.
I would cook it at 350 for 30 minutes covered. Then, uncover and cook until desired done-ness. I like medium rare which is generally achieved in an additional 15-30 minutes. For more tender meat you can cook at a lower temperature for a longer time.
7 hours @ 250 for a rare roast
15 minutes per pound for medium or 20 minutes per pound for well done.
How do you like your burger cooked: medium, medium-rare, or well-done?
because hamburgers won't allow it to be done.
At 300 degrees F.: Rare: 16 to 20 minutes Medium rare: 20 to 22 minutes Medium: 23 to 25 minutes Well-done: 26 to 30 minutes
The recommended internal cooking temperature for steak to ensure it is cooked to perfection is 145F (63C) for medium rare, 160F (71C) for medium, and 170F (77C) for well done.
for appoximatly 2 hrs depending on how well you want your beef cooked. Both the weight of the meat and cooking temperature will affect how well the meat is cooked. How you like your beef rare, medium rare, medium, medium well done and well done will be up to individual taste. Cook meat slightly longer to ensure it's well dine (but not burnt). Reverse cooking time for meat to be rarer. Tip: if you are cooling a roast and you have guests that like their meat cooked to either rare or well done or in between. Cook the meat to nearly cooked, this way, the meat at the outsides of a joint will be well done and as you cut to the centre of the joint, the slices will become less cooked (rare).
How long you would cook a 2.2 pound beef roast depends upon how you like it cooked. For a rare beef roast, cook at 200 degrees Celsius/390 degrees Fahrenheit for 30 minutes. For a medium beef roast, cook for 45 minutes or for well done meat, cook for an hour.
