Notes
You can use any shredded cheese you like, this recipe uses cheddar and mozzarella. But, it’s a great time to use up any leftover cheese in your fridge!
If you want to make this a few days before serving, cover with plastic wrap before baking, and store in the fridge. Allow the baking dish to come to room temperature before baking according to the directions.
