Add pasta to a 9x13-inch aluminum baking pan. Cover with water. Cover well with foil and bake for 30 minutes.
Remove pan from oven and drain water as much as you can. It is not necessary to use a colander; simply pour water into the sink using the foil to help you keep the pasta from falling out.
Toss with vodka sauce, heavy cream, and 2 tsp salt. Cover and bake an additional 45 minutes. Uncover, season with remaining salt (or to taste) and enjoy.
