👩‍🍳 How to Make Potato Cakes

1. Mix the Batter

In a bowl, combine mashed potatoes, egg, flour, cheese (if using), green onions, salt, and pepper. Mix until a soft dough forms. If it's too wet to shape, add a little more flour. If it's too dry, add a splash of milk.

2. Shape into Patties

Scoop out about ¼ cup of the mixture and form into small, flat patties about ½ inch thick.

3. Heat the Pan

Heat a skillet over medium heat and add oil or butter (or a mix of both) until hot.

4. Cook Until Golden

Place patties in the skillet, without crowding. Cook 3–5 minutes per side until golden brown and crispy.

5. Drain & Serve

Remove from pan and let drain briefly on a paper towel-lined plate. Serve hot with your favorite toppings.

🧊 Storage & Reheating

• Refrigerate leftovers in an airtight container for up to 3 days.

⚖️ Tips for Best Results

• Cold mashed potatoes work best — they’re firmer and easier to shape.

• Don’t crowd the pan — give the cakes room to crisp.

• Use enough oil — for that perfect golden crust, don’t be shy with oil or butter.

• Add flour gradually — start small and increase only if the dough is too soft to hold its shape.
