Recently I went to Panera while out to the mall and had their Mac & Cheese. Delicious! This is my attempt to re-create it

1 (16 oz) PKG Pasta
3 T Butter
2 T Flour
1 T Garlic Salt
1/4 t Pepper
2 C Milk
12-13 oz White Cheddar

Cook pasta according to package directions and drain.  Use the same pan and melt the butter over medium heat. Stir in the flour and seasonings. Cook for a couple minutes, whisking frequently. Stir in the milk a little at a time, mixing constantly. Stir in the cheese and mix until well melted and very smooth. Return pasta to pan and mix well to coat.
