Pour your frying oil of choice in your pan at least 1/2 inch deep.

Start heating your grease. You want it from 350-360 degrees.

Put your cold leftover mashed potatoes in a mixing bowl. Add your flour, egg, and other seasonings, if needed, and mix together until incorporated. You will want a thick potato mixture.

Spoon your potato mixture into your hot oil. Dip your silicone spatula or back of spoon in frying grease so it doesn't stick to potato fritter, then gently smash out a patty from your potato dollop. You can put them in the skillet in patty form, but we prefer the more crumbly edges this way.

Fry for 3-4 minutes on each side, or until the internal temp is around 150 degrees and the fritters are a golden brown color.

Let rest on a paper towel lined plate to absorb any excess oil.

Serve with your favorite dipping sauce, garnishes, or enjoy as is!
