Here's my recipe - It's not a recipe that needs baking (although you can if you want) so it's just as quick as making "the blue box." My son and his friends like it so much that when I offer to make them Mac & Cheese they always ask "box or homemade?" and if it's boxed they turn it down!
I also add veggies to it a lot of the time (broccoli, carrots, peas, cauliflower - what ever I have around)
Quick & Easy Mac & Cheese
1 lb. small noodles (shells, elbows - whatever shape you want)
1/2 cup butter
1 cup milk
4 cups (1 lb.) shredded extra sharp Cheddar cheese
1/4 cup shredded parmessean cheese
2 Tbls. cornstarch
1/4 tsp. dry mustard
1/4 tsp. paprika
salt and pepper to taste.
Cook your noodles per the package instructions. While they are cooking, shred cheese and mix cornstarch, dry mustard, paprika, salt and pepper into cheese.
When noodles are done, drain well. Add butter to pan and melt, then add milk. Let it warm a bit, then add cheese mixture. Stir until cheese is melted, then add noodles. Mix it all up and serve! Dinner in less than 30 minutes!
Enjoy.
