You have many options if you want to cook the top round roast. You can cook it whole or cut it into kebabs. If you choose to cook the whole top round, you should allow it to rest for about one hour or two hours before carving it. This will allow the juices to redistribute and make carving easier. Another great way to cook the top-round is to marinate it in an infused marinade for at least one hour. Then, when the roast is ready, you can cut it into kebabs or slices.
