Yes, you can make this recipe ahead of time. I recommend only making it a day in advance as it only lasts 2-3 days in the fridge. Follow the recipe through step six (including a sprinkle of cheese on top of each bowl), then refrigerate the mac and cheese. When you're ready to eat it, continue with the last step. You will need to add a few extra minutes, as the mac and cheese will be cold right out of the fridge.
