This is rich but pretty tasty. It definitely benefits from caramelizing the onions in the butter. Not having any croutons on hand, I used crushed saltines with butter for the topping. I reduced the recipe by half and, depending on the number of servings I need next time, I may even reduce it to a quarter, although the leftovers seemed to taste even better; heated in the microwave and then run under the boiler to crisp the topping. I'll add this to my rotation of mac and cheese recipes.
