Preheat oven to 400°F and lightly grease a 10-inch deep-dish pie plate. Set aside.
In a large bowl, combine 2 cups of the cheese, the ham, and macaroni and mix together. Spread in pie plate.
In a blender, blend together milk and eggs until smooth. Add bisquick mix and salt and, again, blend until smooth. Pour over mixture in pie plate.
Bake until a knife inserted into the center comes out clean, 35-40 minutes. Sprinkle with remaining cheese and bake until cheese melts, just 1-2 minutes more. Let stand 10 minutes before serving. Sprinkle with parsley, if using. Enjoy!
