Step 7: Roast at reduced heat

Reduce the heat to 325°F. If your roast is 4 pounds, roast it for 1 hours 45 minutes more for medium, or 2 hours for medium well done.

If your roast is more or less than 4 pounds, roast it for approximately 25 to 30 minutes per pound for a medium roast. The temperature for a medium roast (pink all the way through) is 135°F – 145°F; the temperature for a medium well roast (tan with some pink) is 145°F – 155°F.

Remove the roast when it is about 5 – 10 degrees below your desired temperature because it will continue to cook as it rests.

Let your roast rest 15 to 30 minutes before serving. Tent with foil to keep warm.

Cut the roast into slices and serve, optionally with a side of gravy. For leaner cuts of meat, slice thinner.

Here are some popular cuts of meat to use:

  • Rump Roast
  • Top or Bottom Round Roast
  • Eye of Round
