Begin by gathering all your ingredients and preheating your oven to 375°F (190°C).

If using fresh potatoes, peel, cut into chunks, and boil in salted water until fork-tender, about 15-20 minutes. If using leftover potatoes, reheat in a pot or microwave.

In a large mixing bowl, mix the warm mashed potatoes with shredded cheese, eggs, flour, salt, and pepper until well combined.

Shape golf ball-sized portions of the mixture into round puffs and place on a parchment-lined baking sheet.

Transfer to the oven and bake for 20-25 minutes until golden brown and crispy on the outside.

Let the puffs cool slightly on the baking sheet for a few minutes before serving warm.
