Sure you can! You have two options. One is to prep up the entire dish except for adding the cheese on top. When you're ready to cook it, remove the dish from the fridge and cook as directed (ONLY if you have a tempered dish that is safe to move from the fridge directly to the hot oven). You may need to cook covered an additional 10-15 minutes since the dish will be slightly cold. You can also cook the dish all the way through and then reheat for dinner 2-3 days later, adding a little bit more cheese to freshen it up at serving time.
