The USDA recommends steaks and roasts be cooked to 145°F (medium) and then rested for at least 3 minutes.
A moderate oven temperature is often a range of 180 to 190 C (350–375 F), and a hot temperature is above 200–230 C (400–450 F). A fast oven would have a range of 230–260 C (450–500 F).
Medium Rare: 130°–135° Medium: 140°–145° Medium Well: 150°–155° Well Done: 160°–165°
To roast a whole joint preheat the oven to 180°C/160° fan/gas 4 and weigh the joint (with any stuffing, if using) in order to calculate the cooking time. Place in the centre of the oven; Rare – cook for 20 minutes per 450g plus 20 minutes. Medium – cook for 25 minutes per 450g plus 25 minutes.
The internal temperature should reach: Beef and lamb: rare 60°C; medium 65°C to 70°C; well-done 75°C. Need a thermometer?
Preheat the oven to 250 degrees celsius. Brush beef with oil and season well with sea salt flakes and freshly ground pepper. Place beef in a roasting pan and place in the oven 15 mins to roast. Reduce the oven temperature to 200 degrees celsius and roast for a further 25-30 minutes per 500g for medium.
When cooking a roast in the oven, keep it uncovered until roasted to the desired doneness. After removing from the oven, tent with foil and let stand 15 minutes before carving. This allows the juices to redistribute, preventing them from draining out during carving—and preventing dry, disappointing meat.
Bring the internal temperature to 135°F (for medium rare meat), 145°F (for medium meat), or 150°F (for medium well). The size and shape of your roast makes a difference in cooking time. As a general rule of thumb, at 225°F, cook your roast for about 30 minutes per pound, after the initial browning (for a medium rare).
As a guide: well done is 77°C, medium 71°C and medium rare 63 °C (leave to rest for 3 minutes) Pork in whole cuts can be cooked like red meat, but is better quality if pork steaks and pieces are cooked to 70°C and roasts to between 70°C and 75°C. Fish fillets can be cooked to around 69°C or when flesh flakes easily.
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.
Low temperatue cooking is ideal for roasting the best cuts of meat which are lean and very tender. It is not the same as slow cooking, which is a method of cooking humbler cuts of meat with liquid to tenderise them.
However, when you are roasting shoulder, round or rump roasts, the doneness temperatures should be adjusted 5 degrees higher; for best results, cooking beyond 145 degrees is not recommended. For narrower-shaped cuts of beef, such as eye of round, roast at 170 degrees for 2 hours per pound.
Medium-High Heat (375 to 400 degrees)
Direct grilling, indirect grilling, smoke-roasting, plancha, and salt slab grilling. Use for chicken pieces, planked fish, large vegetables.
Medium heat is a safe heat setting for cooking because it usually does not overcook food like higher heat settings. Use medium heat to make foods like scrambled eggs, quesadillas, fried onions, and rice. Medium-High Heat: Medium-high heat is between the middle and the highest setting on the knob of the stove.
However, on most stovetops, medium-high heat is usually around 6-7 on a scale of 1 to 10, where 1 is the lowest heat setting, and 10 is the highest.
Answer: 180° Celsius is equal to 356° Fahrenheit.
Regardless of the size of your roast, aim for cooking at 375 degrees F (190 degrees C), for 20 minutes per pound. After resting for 15 to 20 minutes your roast should reach its final internal temperature, which could be 5 to 15 degrees higher than when removed from the oven.
