Make Ahead:

Make this dish ahead until just before baking. Wrap the dish and refrigerate until ready to bake. Take it out of the fridge for at least 1/2 hour before baking so the dish isn’t super cold going into a hot oven.

Leftovers of these mushroom dill scalloped potatoes are excellent. Just heat up the next day. Sprinkle a little more Swiss cheese on your leftover potatoes to jazz them up a bit. Enjoy!
