Absolutely! You can definitely cook raw steak in a crock pot. Slow cookers are designed to cook food over a long period of time, which makes them ideal for tenderizing tougher cuts of meat like steak. The low and slow cooking process allows the steak to become wonderfully tender while absorbing the flavors of the sauce and seasonings. Just remember, always cook the steak on low for an extended period to ensure that it is both safe to eat and deliciously tender.
