Cheesiest Macaroni And Cheese - cooking recipe

Ingredients

1 lb macaroni (I use either elbows or springs)
4 cups milk
1 1/2 lbs shredded cheddar cheese (I prefer to shred myself)
1 lb mozzarella cheese
4 tablespoons flour
1/2 cup butter
1/2 medium onion, diced small
salt and pepper

Preparation

This step will take approximately 20 minutes, so preheat oven to 350\u00b0 while working on this step.
Put macaroni to boil.
In a medium pot heat butter and saute onions.
Add milk, flour, salt and pepper; bring to a rolling boil.
Slowly add cheddar cheese, stirring while adding.
After cheddar has dissolved, add the mozzarella, stirring while adding.
Drain macaroni.
Add macaroni directly to the cheese mixture in the pot.
Pour mac and cheese mixture into large lasagna pan.
Put in oven and bake for 30 minutes or until top is bubbly and golden brown.
