One of the great things about mashed potatoes is that the leftovers can go a long way. While variations abound, leftover mashed potatoes make a killer ingredient for croquettes.
A croquette is essentially any mix of meat or vegetables that's bound together and shaped into a ball or patty, then coated in breadcrumbs and deep fried.
Use your leftover mashed potatoes cold for the best results. To ensure you can roll your mixture to hold its shape, add a little flour to help keep it together.
Heat your oil to the ideal temperature, around 350 degrees Fahrenheit, and fry your croquettes until nicely browned and crisped. It only takes a couple of minutes.
