Mac 'n' cheese with dry mustard

For so many years, it was easy and fun to prepare “mac’n’cheese” out of a box. The slight cardboard flavor was overruled by the tremendous ease of boiling and either squeezing the tube of fake cheese or stirring in the powdered "cheese"!

Home-made recipes seemed to include lots of cheeses and more complicated steps that I “didn’t have time for” until this healthier gem was printed:

I made only slight modifications, by using fat free milk and sour cream, and adding onions and garlic. I’m grateful (pun intended) to the genius who marketed pre-shredded carrots to grocery stores. The first time I made the recipe, I hand grated them, got tired and used the blender blade to shred more, and finally decided that from here on out I’ll get the nifty bag of mass produced carrot shreds.

The dry mustard was a welcome and creative ingredient, adding depth of flavor. I used one bag of cheddar cheese and another cup of a pre-combined mix of cheeses (either "Mexican" or "Italian"). Positive reviews all around!

This last photo was before baking...forgot to take an "after" picture! The 9x13 pan was a double batch for a crowd. Do you have a favorite home made mac'n'cheese recipe that you can share?
