Yes, you can! 1. Tightly wrap in plastic wrap. 2. Add the plastic-wrapped beef to a zip-lock freezer-safe bag. Squeeze all of the air out and make sure it's sealed tightly. 3. Place the bag in the back of the freezer so it reaches freezing temperature more quickly. Enjoy your leftover holiday roast no more than 2 months after freezing and do not re-freeze after thawing. Make sure to label with the freezing date!
