For best results, make sure the spinach is very well-drained to avoid a watery dip, and taste the mixture before baking to adjust salt, pepper, or heat to your liking; you can prepare the dip up to a day in advance and refrigerate it (adding a few extra minutes to the bake time from cold), and feel free to customize by topping with extra mozzarella or Parmesan for a more browned crust or by stirring in additions like finely chopped green onions, cooked bacon bits, or a squeeze of lemon for brightness.
