Prepare rice according to package instructions. Use chicken broth for added flavor.
In a large stockpot add the olive oil and place over medium heat.
Once the oil is heated add the onion and garlic. Cook for about 2 minutes or until the onion has become translucent.
Season with salt and pepper. Add in the red pepper flakes, onion powder, garlic powder, and Italian seasoning. Stir.
Add carrots, celery, and chicken. Stir.
Stir in 5 cups of the chicken broth. Bring the soup to a boil then cover and reduce the heat to low. Allow to simmer for 20 minutes.
To serve, add a quarter of the rice (about ½ cup) to bowl. Spoon soup over the top of the rice.
