While there's a lot to be said about a baby vs adult bearded dragon's diet; I'm going to be focusing on the adult bearded dragons for this article.

One important difference is: Adults require 80% veggies and 20% protein while the opposite applies to babies.

Staple Foods

A staple for the adult bearded dragon is going to be their greens. They need a fresh mixture of various greens every day. (Although some are very stubborn and don't always eat their greens, they should still be offered every day.)

Suitable Greens

  • Collard greens
  • Mustard greens
  • Turnip greens
  • Endive
  • Escarole
  • Dandelion greens

Examples of Vegetables to Add to the Salad

  • Butternut squash
  • Yellow squash
  • Peas
  • Carrot shavings
  • Cut-up green peppers

Foods You Can Add Every Once in Awhile

  • Dandelions (the flower part)
  • Bok choy
  • Cut-up blueberries

Mine also love eating clovers in the yard but make sure that there aren't pesticides used where they will eat outside. I also wash off the dandelions.

It's important to provide a variety of greens and different combinations so they don't become bored and get a lot of different nutrients.

Dandelions can be an occasional part of your bearded dragon's diet.

Sources of Protien

I recommend offering various insects every other day or every three days.

Insects You Should Offer Often

Dubia roaches

  • These are my number one recommendation for a staple.
  • Offer five to six each meal.
  • They are full of protein and very nutritious for your bearded dragon.
  • Lightly dust with calcium and multivitamin twice a week.
  • I also feed my Dubia roaches greens that my lizards would eat to gut load them full of nutrition.

Phoenix worms

  • These are naturally a good source of calcium so will not require dusting.
  • Can offer up to 10-20 in a serving.

These are also perfectly okay to offer often but are a bit more expensive than the others.

Insects to Feed Occasionally


  • Feed about two to three each serving once a week or every other week.
  • They are a wonderful treat that bearded dragons go crazy for!
  • They provide lots of hydration so too many can cause watery stool.


  • Another one of bearded dragons' favorite treats that should also be given sparingly.
  • They are a high-fat food and also high in phosphorus.
  • The high amount of phosphorus contracts with the calcium, meaning superworms should always be dusted with calcium each time they are given.
  • Should only be given as a treat; two to three given once or twice a week is okay mixed in with their staple foods.


These are also high in fat but a delicious treat to give every once in a while.

Poisonous foods

Avocados and lightning bugs (fireflies) are fatal when eaten by a bearded dragon so never let these near your beardies.

The rule of thumb is that if you aren't sure if something is safe for them to eat, don't offer it until you know for sure. Never offer wild-caught bugs that can carry parasites.

Supplemental Nutrition

As mentioned above, most feeders will need to be dusted with calcium (I recommend with vitamin D3 to help them absorb the calcium) and a multivitamin. Pictured below is what I use. Unless you are feeding Phoenix worms, feeders will need to be dusted at least twice a week.

This is the multivitamin that I use once or twice a week.


While reptiles don't often need water daily, be sure to offer it at least twice a week by either dripping some onto their nose until they stop licking or under a slow-running faucet. Bath time is an excellent time to make sure they are getting their water intake!

I hope this simple guide was helpful to you; these were not all-inclusive lists but the main staples and basic guidelines that I follow! If you have other foods that your bearded dragons enjoy, drop them in the comments below!

If I ever have a reptile as a pet, it will be a bearded dragon. I think they're lovely animals. Thank you for sharing the feeding instructions, Neena. This is a very useful reference source.
