Advice needed: Accidentally summoned a demon while trying to make mac & cheese

So I was hungry and bored and a little drunk and decided to make some homemade macaroni and cheese. I found this old leather-bound book that looked like a cookbook, so I opened it and followed a recipe. Turns out it was like the Necronomicon or something and I summoned a demon. He’s sitting on my couch right now being a dick, watching Netflix and drinking my beer. He won't leave and says he's going to take my soul unless I make him the world's best mac and cheese. I have a box of crappy dollar store instant mac in the pantry. What can I do to make it better? I don't have any crazy ingredients like fancy cheeses or truffles. Help.
