Baked Mac n Cheese

I have a few Mac n Cheese recipes.  Lately, I've loved this one, as it is EASY and QUICK and DELICIOUS!  Very yummy!  Shaking the flour/milk/onion salt mixture helps make this super-simple and the sauce is creamy and yummy.  The leftovers are even delicious!

ingredients:
8 oz. elbow macaroni
2 cups milk
1/2 cup flour
1 tsp. onion salt
4 1/2 cups shredded cheddar cheese, divided (use different types of cheddar for a great taste)
1 cup soft plain bread crumbs
1/4 cup butter

directions:
1.  COOK macaroni according to package directions; drain well. Set aside.

2.  PLACE milk, flour, and onion salt in a quart (mason) jar; cover tightly, and shake vigorously 1 minute.

3.  STIR together flour mixture, 3 1/2 cups cheese, and macaroni.

4.  POUR macaroni mixture into a lightly greased 13x9 baking dish or 2 (11 inch) oval baking dishes.

5.  Sprinkle evenly with breadcrumbs and remaining 1 cup cheese; drizzle evenly with melted butter.

6.  BAKE at 350 degrees for 45 minutes or until golden brown.
