How to make creamy macaroni and cheese
Prepare.
You'll want to prepare all of your ingredients before you start cooking, so everything is ready to go!
Shred your cheeses.
Start by shredding your cheddar cheese if it isn't already.

Options:
[1]. To make it easier, save the cheddar and parmesan. You can either shred them or grate them, but it's a whole lot easier to shred those cheeses too.;
[2]. It's easier and cheaper to shred if done inside a large saucepan than if you're piping it in the oven. You can use cubes of cheddar, if you like.;
[3]. Don't use a food processor if it is frozen. Go ahead and use your cheese knife if that's your preference.;
[4]. Also cube your velveeta so it melts down better. Bacon time! If you're going to add the bacon, then you'll want to precook it.;
The answer is:
[4].
