If you want to make your New York strip roast even more tender, here are 3 tips you can use:  Use a marinade: This gives the roast extra flavor while also helping break down the proteins in the meat. A marinade with an acidic ingredient, such as vinegar or citrus juice, will help to tenderize the meat further.  Pound it out: Use a mallet and gently pound your roast to help break down the muscle fibers. Doing this also helps flatten the roast out for even cooking.  Dry brine: This is a simple process of salting the meat about 30 minutes before cooking. The salt draws out the New York strips moisture, which is then reabsorbed, creating a juicier and more tender roast.
