A basic southern-style pimiento cheese spread is combined with macaroni and baked to perfection with a crunchy french fried onion topping. I add some onion powder to the cheese mixture, but a teaspoon or two of fresh grated onion can be added instead. Add a dash of garlic powder to the dish or rub a split clove of garlic over the bottom and sides of the baking dish before buttering. Use regular or gluten free macaroni in this easy casserole.
