Don't overmix the potatoes after adding milk to avoid gluey texture - beat just until combined for the fluffiest results.
Warm the milk before adding to prevent cooling down the hot potatoes and ensure smooth incorporation.
Let the casserole rest 5 minutes after baking to allow the cheese to set slightly before serving.
