Step 1

Heat oil in a large pot over medium heat. Add orzo and cook, stirring constantly, until lightly toasted, about 1 minute. Add wine and cook, stirring occasionally, until the liquid is absorbed, about 30 seconds. Stir in 2 cups water and 1 cup broth; bring to a boil over high heat. Reduce heat to maintain a lively simmer and cook, stirring occasionally, until most of the liquid is absorbed and the pasta is almost tender, about 5 minutes.

Step 2

Add zucchini and garlic and cook, stirring occasionally, until most of the liquid is absorbed and the zucchini is tender, about 2 minutes. Stir in chicken, cream cheese, 1/4 cup Parmesan, parsley, tarragon (or dill), pepper, salt and the remaining 1/2 cup broth. Cook, stirring constantly, until creamy and hot, about 2 minutes. Sprinkle with the remaining 1/4 cup Parmesan.
