Notes
What to do with Leftovers
Leftovers will last in an airtight container in the fridge for 4-5 days. For longer storage, freeze single-serve portions for up to 3 months.Reheat potatoes in the microwave until hot; stir occasionally so they heat through evenly. Add a splash of milk to thin them out, if needed. Pan-fry mashed potatoes in butter until they are crisp and golden on both sides.Add egg, flour or bread crumbs to make potato cakes or croquettes. Top shepherd's pies with leftovers.
