4 cups medium shells (almost a whole box)
5 Tablespoons unsalted butter
¼ cups flour
2-½ cups skim Milk
2 teaspoons dry Mustard
1 egg
1 pound cheese, I used sharp cheddar and an italian blend
½ teaspoons Salt (and don’t forget to salt the water when boiling the pasta)
1/2 tsp dijon mustard
½ teaspoons ground pepper
Optional Spices: Paprika, hot sauce (which I put some in)
Cook pasta till firm and drain. Melt butter and add flour and stir for 5 minutes. Don’t let it burn. Add spices and milk, stir until combined. Add cheese and everything else. Dump in the pasta and stir. Put into an oven-proof pan at 350 for about 25 minutes. I topped mine with homemade croutons and parm cheese.
Delicious!
