Yes, you can safely cook a beef rib roast that has been frozen for 18 months, as long as it was stored at a consistent temperature of 0°F (-18°C) or lower. While the quality may decline over time, including changes in texture and flavor, it should still be safe to eat. Make sure to thaw it properly in the refrigerator before cooking to ensure even cooking and food safety. Always check for any off odors or signs of freezer burn before preparing.
