In a mixing bowl, combine shredded cheese, grated Parmesan, paprika, salt, and pepper. Mix well until evenly incorporated.
Add the beaten egg to the cheese mixture and stir until the mixture becomes sticky and slightly cohesive.
Sprinkle in the panko breadcrumbs gradually, folding them into the mixture until it holds together and is easy to form into balls.
Using a small scoop or spoon, portion out golf ball-sized amounts of the mixture. Roll each portion between your palms to form smooth, round balls.
Place the cheese balls on the prepared baking sheet lined with parchment or a silicone mat, spacing them about 2 inches apart.
Lightly spray or brush the tops of the cheese balls with oil to help them crisp up evenly during baking.
Bake the cheese balls in a preheated oven at 200°C (390°F) for 15-20 minutes, or until they turn a deep golden brown and develop a crispy exterior.
Halfway through baking, gently turn the cheese balls with a spatula to ensure even coloring and crispiness.
Remove the baked cheese balls from the oven and let them rest for 3-5 minutes; they will be hot and melty inside but crisp on the outside.
Serve the cheese balls warm, garnished with a sprinkle of fresh herbs or with your favorite dipping sauce for an extra touch of flavor.
