FAQ
Can I freeze these mashed potatoes?
Yes, freeze in covered casserole up to 2 months. Thaw overnight in refrigerator before baking with reserved cream mixture.
What if I don't have heavy cream?
Substitute half-and-half or whole milk, though texture will be slightly less rich. Avoid low-fat milk which makes potatoes gummy.
How long do leftovers keep?
Store covered in refrigerator up to 3 days. Reheat portions in microwave or warm entire dish in 300°F oven until heated through.
