For a variation, you can add a layer of sautéed mushrooms between the pork chops and potatoes for an earthy flavor. If you prefer a spicier kick, add a pinch of red pepper flakes to the cheese sauce. Those looking for a lower-calorie version can use sweet potatoes instead of regular potatoes, as they offer a different texture and natural sweetness. Finally, for an even richer dish, consider adding a layer of cooked bacon bits on top of the casserole before baking.
