For a lower carb version of this use Dreamfields lower carb pasta on its own or mix in steamed cauliflower with the pasta (use half of the amount of pasta) and of course don't top it with potato chips.
2 boxes of penne pasta (or any tube shape of your choice) cooked and drained
1 stick of butter
1/2 cup flour (use whatever kind you have, I used white whole wheat)
3 cups milk (any type)
3 cups chicken broth (or veggie broth)
6 cups shredded cheese of your choice (I like gruyere, sharp cheddar, and a mild cheddar). Separate cheese into a 4 cup portion and a 2 cup.
2 tsp. dried mustard (or 1 tbsp. dijon)
2 tbsp. Onion Onion (dried onion or 2 tsp. onion powder)
1 tsp. salt
2 tsp. pepper
4 cups shredded chicken
1 cup Frank's Hot sauce (change the amount according to your taste)
Crushed potato chips (optional)
Preheat oven to 350 degrees.
In a medium bowl toss the chicken with the hot sauce and season with salt and pepper.
Ladle in 1/2 of the mac and cheese mixture. Top with chicken and 1 cup of shredded cheese.
Cover it with the other 1/2 of the mixture. Top with shredded cheese and crushed potato chips. Bake in the oven for 30-40 minutes until is is browned and bubbly. Remove for the oven and let sit for 20 minutes.
