Add the dried orzo pasta, and mix well to coat the orzo with the butter.
Stir continuously, and sauté until the orzo is lightly golden brown, about 3 – 4 minutes.
Then add the chicken broth and bring to a low boil. Reduce the heat to low, cover and let simmer until the orzo has soaked up the liquid, about 15 minutes. Make sure to stir often, to prevent burning to the bottom of the pan.
Then add the lemon juice and zest, and simmer for about 2 more minutes.
Stir in the cream and parmesan cheese, then simmer for 2 minutes.
