Cook for approximately 12 minutes, or until the top layer of the mac & cheese turns golden brown.
Allow to cool and enjoy!
A few notes:
(1) this recipe produces a fairly dry mac & cheese. For those who prefer a creamier mac & cheese, consider adding more milk.
(2) The cooking times were the ones prescribed in the TV program. When I did this, it did not produce the thick brown layer on top. Consider cooking at a slightly lower temperature for a bit longer, followed by turning on the broiler for a few minutes if you would like to recreate the crust shown on the TV program.
(3) This makes for great leftovers! Simply add 1-2 tablespoons of milk to the mac & cheese and microwave until warm.
