Ingredients 
Roast for about 13-15 minutes per pound for rare, 17-19 minutes for medium, and 22-25 for cooked through. Check the meat with a thermometer to make sure it is the temperature you want it: 145°F for medium rare, 160°F for medium.
We suggest planning 30 additional minutes. Approximately 15 minutes for searing the roast at 450 °F prior to roasting and approximately 15 minutes for the roast to rest before serving .Common Names.
Cook for 20 minutes a pound. A 3.5 lb roast takes about 1 hour and 15 minutes for a rare roast, but watch the thermometer reading. After you cook it for 20 minutes a pound, take it out of the oven, let it sit for 1 minute and then check the thermometer reading.
Do not cover the roast and do not add any liquid (liquid is used for braising, not roasting). Remove the roast from the oven and place aluminum foil loosely over the meat to hold in the heat. Let the roast stand for 15 minutes. The temperature will continue to rise 5 or 10 degrees, reaching the proper doneness.
Here's what I do: I put a rack in the bottom of a roasting pan. Then I place the roast (no rubs or seasonings) on the rack and cover it with a lid. I put it in the oven at 400° for 15 or 20 minutes, then turn it down to 325° and roast for 30 minutes per pound. All it does is end up tough, chewy, and well-done.
Bring the beef out of the fridge 1 hr before roasting.) Heat oven to 190C/170C fan/gas 5 and sit the joint in a snug-ish roasting tin. Roast for 12 mins per 450g/1lb (about 55 mins for a 2kg/4lb 8oz joint) for medium-rare, or 15 mins per 450g/1lb (about 1 hr 10 mins) for medium-well.
Preheat your oven to the correct temperature to ensure your cooking time is accurate: 220C/Gas 7/fan 200C. Cook larger roasting joints on a high heat for the first 20 minutes to let the heat really penetrate the meat and give it a good crust on the outside. Good to read: chicken breast bake.
How long do you cook a 2 lb roast at 350 degrees? Cook at 350 degrees F for 20 for 25 minutes per pound.
How long does it take to cook a 3 pound roast at 350 degrees? Cook at 350 degrees F for 20 for 25 minutes per pound.
How long does a frozen roast take to cook in the oven? Place the roast on the rack and put in the oven for 25-30 minutes. Keep an eye on it every 10 minutes because it's going to get hot. You want a dark-brown crust to surround the meat.
Roast your beef, uncovered, to the desired doneness. After removing from the oven, tent with foil and let stand 15 minutes before carving. Roasts weighing over 8 pounds should be loosely covered halfway through roasting to avoid over-browning.
Preheat the oven to 250 degrees. Roast for about 25 minutes per pound of meat. Check the temperature 30 minutes early. You want 130° for medium-rare.
If it's not cooked correctly, that same cut of meat can be distressingly tough, chewy or dry. A failed pot roast can result from undercooking, overcooking or choosing the wrong cut of meat, so before you can fix it you'll need to decide where you've gone wrong. Read about beef roast marinade recipe.
Add the stock pot and enough boiling water to come a third of the way up the meat (rinse out the frying pan with it to collect any residual flavour). Transfer the meat to the oven, cover with a lid and cook for 6 hrs turning once or twice during cooking, until really tender. Further reading: beef roast cook.
Moral of the story: If you've got the time, salt your meat for at least 40 minutes and up to overnight before cooking. If you haven't got 40 minutes, it's better to season immediately before cooking. Cooking the steak anywhere between three and 40 minutes after salting is the worst way to do it.
Do you cook beef roast with netting on? Leave it on. The idea behind the netting is to hold the roast in a firm and tight hold while it cooks so the meat does not fall apart or loosen up and spread. Assuming cotton, you just sear your roast with the netting on and then drop it into the oven.
Reduce the heat to 190C/375F/Gas 5 and roast for half an hour per kilo for rare, adding another ten minutes per kilo for medium rare, 20 minutes per kilo for medium, and 30 minutes per kilo for well done. Remove the beef from the oven, transfer it to a carving board and cover with foil.
Brown in a 230°C oven for 20 mins, turn down to 150°C and add a little water to the pan. Cook for 25 mins per 500g (add/subtract 15 mins for well done/rare). Rest for 15 mins under foil and add any juices to the gravy.
Brown in a 220°C/Gas 7 oven for 20 mins, then turn down to 160°C/Gas 3 and add a little water to the pan. Cook for 20 mins per 500g (add/subtract 15 mins for well done/rare). Wrap in foil and leave somewhere warm to rest for at least 15 mins before carving.
Add water, wine or broth to about an eighth of an inch high in the pan. You may need to replenish it during cooking. This will keep drippings from scorching. Toward the end of roasting, let the liquid evaporate so that the drippings can brown for about 15 minutes.
