This loaded mashed potato casserole is the ultimate comfort food—creamy, cheesy mashed potatoes topped with crispy bacon, sharp cheddar, and fresh chives, baked until golden and bubbly. Perfect for cozy nights, holiday dinners, or any time you need a dish that feels like a hug.
Don’t over-mash potatoes to avoid gluey texture. Warm milk before adding. Season cooking water generously. Watch broiler closely to prevent burning. Let casserole rest before serving. Use room temperature cream cheese for best blending. For make-ahead: assemble, refrigerate unbaked, add 10 minutes to baking time. Leftovers keep 4-5 days in fridge or freeze up to 3 months.
