This creamy, cheesy mashed potato casserole is lightened up with Greek yogurt and chicken broth, then topped with crispy onions and turkey bacon for a healthier twist on comfort food.
Add crispy onions only at the end to prevent burning. Use room-temperature yogurt and butter for best texture. For a vegetarian version, skip bacon and add sautéed mushrooms and sun-dried tomatoes.
