1. Preheat oven to 425 degrees Fahrenheit (220 degrees Celsius).
2. Combine all ingredients aside from 3/4 cup cheese in a nine- x 13-inch (20- x 30-centimeter) pan. Cover tightly and bake for 45 minutes.
3. Uncover and sprinkle with remaining cheese. (If the pasta looks too watery when you uncover it, leave it in the oven uncovered for 10 minutes, or as necessary, to allow the extra water to evaporate before sprinkling it with cheese.)
4. Return to the oven for an additional 10 minutes. Remove from oven and let stand 10 minutes before serving.
