Recipe Yield: 6–8 cakes
INGREDIENTS
2 cups cold mashed potatoes
1 large egg
1/3 cup all-purpose flour
INSTRUCTIONS
1. Mix the batter: In a large bowl, combine the mashed potatoes, egg, and flour. Stir until the mixture is smooth, thick, and scoopable. If your mashed potatoes are very soft or creamy, you may need an extra tablespoon of flour to hold the cakes together.
2. Shape the cakes: Scoop about 1/4 cup of the mixture and gently flatten into small patties, about 1/2 inch thick. Place them on a plate or parchment-lined tray while the skillet heats.
3. Pan-fry until golden: Heat 1–2 tbsp of oil in a nonstick skillet over medium heat. Once hot, carefully add the potato cakes (don’t overcrowd the pan). Cook for 3–4 minutes per side, or until golden brown and crispy. Transfer to a paper towel-lined plate. Repeat with remaining cakes, adding more oil as needed.
4. Serve warm: Enjoy immediately while the outside is crisp and the inside is soft. Serve with sour cream, green onions, or your favorite dipping sauce.
Helpful Tips to Perfect This Recipe
- Use Cold Mashed Potatoes: Cold mashed potatoes from the fridge work best—they’re stiffer and easier to shape, helping your cakes hold together.
- Don’t Skip the Flour: The flour binds everything and creates that golden crust. Add a little more if your potatoes are extra creamy.
- Medium Heat for Crispy Texture: Pan-fry over medium heat—too hot and they’ll burn before cooking through, too low and they’ll absorb oil.
