How do you  cook frozen pot pie in oven?
 Preheat your oven to 425 degrees Fahrenheit. Unwrap the pot pie and place it on a cookie sheet. Cover the edges of the pie with aluminum foil. Cook the pot pie for approximately 20 to 30 minutes. Remove the aluminum foil. Reduce the oven temperature to 350 degrees Fahrenheit. Bake until the crust turns golden. This can be as long as 70 to 80 minutes if you are cooking two large pot pies. For a single pot pie, cook it for about another 40 to 50 minutes.
