When I have leftover mashed potatoes, I often make gnocchi. But I wanted something to go with steak, so a couple of weeks ago I made potato croquettes from Thanksgiving mashed potato leftovers. They were fantastic: I'll make extra potatoes in the future just so I can make these again! I started with a Paula Deen recipe and tweaked it a little to make it not so rich. Everyone in the family loved them, though of course Ben ate them with ketchup!
2 tablespoons milk
1/2 teaspoon pepper
1/2 teaspoon chopped green onion or other kind of onion - can use more.
2 egg yolks, beaten
3 tablespoons all-purpose flour
4 cups mashed potatoes
1 egg, beaten
Sifted dried bread crumbs (I used panko)
Peanut oil or vegetable oil, enough to coat frying pan
Add milk, salt, pepper, chopped onion, beaten egg yolks and flour to mashed potatoes. Chill and then shape into a flat pancake, about 3/4 inch thick. Dip in the beaten egg, then roll through bread crumbs. Fry each croquette in oil, turning to brown on both sides.
Cook in small batches, making sure croquettes do not touch. Add more oil if needed.
