Old Fashioned Macaroni and Cheese

Ingredients:

2 cups uncooked elbow macaroni
4 tablespoons butter
2 tablespoons all-purpose flour
2 cups milk
1/4 onion, minced
Salt and pepper to taste
1 cup sharp cheddar cheese
1 cup mild cheddar cheese
1 cup Monterey Jack cheese
Butter, to taste

Directions: 

1. Preheat oven to 350 degrees.
2. Prepare the elbow macaroni according to package directions.
3. Meanwhile, melt the butter in a small saucepan over medium high heat. Stir in the flour until a cream colored paste forms. Then pour in the milk and stir constantly until this comes to a hard boil, and then stir for 1 more minute. Remove from heat and set aside.
4. When the macaroni is cooked, spread 1/2 of it into the bottom of a lightly greased 9x13-inch baking dish. Then layer 1/2 of the grated onion, 1/2 of the salt and pepper and 1/2 of each of the cheeses. Repeat this one more time: macaroni, onion, salt and pepper and cheeses, and then pour the reserved sauce over all. Top off with small pats of butter to taste.
5. Cover and bake at 350 degrees for 45 minutes.
