Step 1

Preheat the oven to 300 degrees Fahrenheit.

Step 2

Cover the roast with foil but leave a small gap on top. Into it, pour 1/4 cup of leftover au jus. Close the gap and wrap the entire roast with another layer of foil.

Step 3

Reheat at 10-minute intervals until warmed through. Test for doneness by sticking a meat thermometer into the thickest part of the roast. The temperature should be at least 160 degrees Fahrenheit.

Step 4

Transfer the roast onto a serving plate and let it rest for 5 minutes before serving. Slice and enjoy!
