Preheat your oven to 400°F (200°C).

In a large mixing bowl, combine your leftover mashed potatoes, shredded cheese, flour, egg, and seasonings. Mix until well combined.

Scoop portions and shape them into golf ball-sized balls or patties.

Line a baking sheet with parchment paper and place your puffs on it, leaving space in between.

Bake for 20–25 minutes until golden brown.

Let cool slightly before serving warm with dipping sauces.
