Serving Suggestions
This potato bake excels alongside roasted chicken, where meat juices enhance the creamy sauce. For casual meals, serve with a fresh green salad. During holidays, it complements traditional meats like ham or turkey perfectly.
Recipe Variations
Experiment with cheese combinations like cheddar and fontina for unique flavor profiles. Create a lighter version using half milk instead of cream, or add sautéed mushrooms between layers. For dairy-free needs, substitute with coconut cream and plant-based cheese alternatives.

Store leftovers in an airtight container for up to four days. Reheat with added cream in a 350°F oven until hot. Avoid microwave reheating. Portions can be frozen up to three months when properly wrapped.
