Variations & Tips
For a different twist, try adding a layer of thinly sliced potatoes or sweet potatoes for extra heartiness. If you have picky eaters, you can substitute the heavy cream with a lower-fat option and use a mild cheese like mozzarella. For a gluten-free version, use gluten-free bread crumbs. Feel free to add cooked bacon bits or a dash of nutmeg to the cream mixture for an extra burst of flavor.
