Preparation

Step 1

These estimated roasting times are based on a minimum roast weight of 4 pounds (or 1.8 kg):

Recommended cooking temperature is 325ºF.

For Medium-Rare: Cook for 22 minutes per pound. Internal temperature on the meat thermometer should read 140ºF (or 60ºC) when the roast is removed from the oven.

For Medium: Cook for 25 minutes per pound. Internal temperature should read 155ºF (or 68ºC) when roast is removed from the oven.

For Well Done: Cook 30 minutes per pound. The internal temperature should be 165ºF (or 74ºC) when removed from the oven.

The minutes per pound are a guideline only. Exact cooking time can vary, which is why it is best to use a meat thermometer.

Allow 3 servings per pound of bone-in roast, 4 for a boned roast.
