Can Bearded Dragons Eat Steak?
While bearded dragons can eat cooked, lean meat like steak, chicken, and turkey, only feed it to your beardie unseasoned and as an emergency protein source if, for some reason, you are unable to get their live feeders.
Also, both beef and chicken are very high in phosphorus that binds with calcium, making it useless to your pet. In other words, your bearded dragon will get less calcium absorbed into its system if you feed them steaks and other meats, so make sure to offer these kinds of food as a very occasional treat.
Dubia roaches and other live feeders will provide plenty of protein to keep your reptile happy and healthy, and you can safely stick to them.
