Preheat oven to 450 degrees F.
In a 9x13-inch baking dish combine orzo, broth, condensed soup, sour cream, soup mix, spices, worcestershire sauce, and ½ cups shredded cheese. Stir to combine.
Bake for 35 minutes, then remove from oven and top with remaining 1 ½ cups cheese.
Bake for another 15 minutes or until cheese is fully melted and bubbling.
Serve right away and top with parmesan if desired.
