Make it Vegan: Use vegan cheese and the non-dairy milk of your choice. (I like unsweetened almond milk).
Make it Cleaner: Use nonfat milk, low-fat parmesan and cut the Gruyere in half.
Make it Gluten-Free: Hooray! This dish is gluten-free.
Make it Quick: This dish can be made through step 4 up to 24 hours in advance. Place in the oven cold and preheat oven. Bake for 50 minutes.
