In a 3 quart heavy bottomed saucepan over medium high heat mix together orzo with chicken stock, water, granulated garlic, salt, black pepper and onion powder.
Bring to a boil, then immediately lower the heat and simmer on low uncovered for 15-18 minutes or until all of the liquid has been absorbed. Stir to prevent sticking.
Turn the heat off and add Parmesan and cream. Mix well until fully combined. (There's enough ambient heat to melt the cheese.)
Garnish with additional parmesan and chopped parsley and serve immediately.
