Preheat the oven to 350 degrees Fahrenheit (177 degres Celsius).

Clean, peel and coarsely chop the rainbow carrots. If you cannot find rainbow carrots, regular orange carrots will work too.

In a mixing bowl combine orange juice, broth, onion powder, garlic, honey, sea salt, olive oil and black pepper.

In a casserole dish, place chopped carrots on the bottom and then pour the broth mixture over the top.

If desired, you can now add in cranberries. Cover with a lid, or foil, and bake for two hours.
