Begin with 4 cups of mashed potatoes. If you don’t have any on hand, you can easily make some by boiling peeled potatoes until tender, then mashing them with a bit of butter and milk until smooth.
In a large mixing bowl, combine the 4 cups of mashed potatoes, 2 cups of shredded mozzarella cheese, 1 large egg, 1/4 cup of all-purpose flour, and 2 1/2 tablespoons of chopped chives. Mix until all the ingredients are well incorporated.
If your mashed potatoes are particularly creamy, you may need to add up to 1/2 cup of flour to achieve the right consistency for shaping the pancakes. The mixture should be thick enough to hold its shape but not too dry.
Using your hands, form the mixture into small patties, about 3 inches in diameter. Make sure they are evenly shaped for even cooking.
Place the plain bread crumbs on a plate. Dredge each pancake in the bread crumbs, ensuring they are fully coated. This will give them that irresistible crispy texture.
In a frying pan, heat 2 tablespoons of light olive oil or canola oil over medium heat. You want the oil hot enough that it sizzles when you place a pancake in the pan.
Carefully add the pancakes to the hot oil, leaving space between each one for flipping. Cook for about 3-4 minutes on each side, or until they are golden brown and crispy.
Once cooked, transfer the pancakes to a paper towel-lined plate to absorb any excess oil. Serve them warm with a dollop of sour cream on top or on the side for dipping.
