The secret to cooking lamb perfectly is knowing when it is done. You do not want to cut into a chop or roast to check. When cooking lamb, your best kitchen friend is a good meat thermometer to determine when you should remove your cut from heat. Stop cooking lamb when the thermometer shows 5 – 10° less than your planned temperature. Lamb will gain those degrees while resting. USDA recommends cooking chops and roasts 145º for medium-rare, 160º for well-done. Ground lamb should be cooked to at least 160º. But don’t serve immediately. Resting your lamb will allow the juices to settle. Wait 10 minutes before serving roasts and just five minutes for chops. Use the chart below as a guide.
