Chop the broccoli into fine pieces and place in a fine mesh strainer over a steamer basket pot with one inch of water at the bottom. Cover, bring to a boil and steam until cooked through and just slightly crispy, about 10 minutes.

In a large pot with a tight fitting lid combine 5 cups of the chicken broth, parsley flakes, onion powder, and garlic powder. Cover and bring to a boil. Meanwhile mix the flour with the ¼ cup chicken broth with a whisk until smooth.

Once the chicken broth comes to a boil, pour in the flour mixture and whisk constantly for 1 minute. SLOWLY add in the shredded cheddar, whisking constantly until all the cheese is melted. Add in the cream, and then the broccoli, heat through. Soup will thicken upon standing.
