In a medium saucepan, bring the chicken broth to a boil. Add the orzo pasta and cook according to package instructions until al dente, about 8-10 minutes. Stir occasionally to prevent sticking.
In the last 3-4 minutes of cooking the orzo, add the broccoli florets to the pot. Cook until tender and bright green.
Once the orzo and broccoli are cooked, drain any excess liquid and return the mixture to the pot.
Add the diced cooked chicken, shredded cheddar cheese, cream cheese, olive oil, garlic powder, onion powder, and red pepper flakes (if using) to the pot. Stir well to combine.
Cook over low heat for an additional 3-5 minutes, stirring frequently, until the cheese has melted and everything is heated through. Season with salt and pepper to taste.
Remove from heat and let it sit for a minute before serving.
Notes
Serve in bowls garnished with fresh parsley and extra cheese.
