Why not make some delicious potato patties?

This is a great way to use up mashed potatoes, and they’re super simple to make.

Here’s what you’ll need:

  • 1 cup leftover mashed potatoes (I like to use white or yellow)
  • 1 egg, beaten
  • 1/4 cup flour (you can use all-purpose, but I prefer a gluten-free flour blend)
  • salt and pepper to taste
  • Vegetable oil for frying (about 1/2 inch deep)

To make them:

  1. Heat the vegetable oil in a medium skillet over medium heat until hot but not smoking.
  2. In a mixing bowl, mix together the flour, salt and pepper; stir in the egg and then add the mashed potatoes.
  3. Mix thoroughly, then shape into patties about 1/4 inch thick.
  4. Fry for 3 minutes on each side until golden brown on both sides.
  5. Serve immediately with ketchup if desired!

Top with some shredded cheddar cheese and bake at 375 degrees for about 20 minutes until the edges are golden brown.

14. Add It to Your Morning Eggs

15. Mix It in A Baked Potato Casserole


Here’s another great way to use up your leftovers: bake them into a casserole! Just mix them with some cooked bacon and cheese, then layer it all in a baking dish and bake it until golden brown on top.

This recipe is perfect if you have some extra time on your hands—you can even make it ahead of time so it’s ready when guests come over for brunch or dinner!
