A quick and easy comfort food casserole featuring creamy mashed russet potatoes loaded with crispy bacon, sharp cheddar cheese, and green onions, baked to golden perfection.
Do not over-mash the potatoes to avoid gluey texture. Use room temperature butter and sour cream for easier mixing. Cook bacon crisp but not burnt. Mix gently when folding in cheese and bacon. Tent casserole with foil if cheese browns too fast. Potatoes can be baked ahead and casserole assembled just before baking.
