Prepare the coating by setting up three bowls. In the first, combine all-purpose flour, sea salt, black pepper, and garlic powder. In the second bowl, beat the eggs with a splash of water. In the third bowl, mix panko breadcrumbs and Italian seasoning.

Coat the cheese sticks by first dipping them into the egg mixture, then rolling them in the flour mixture, returning to the egg, and finally coating them in panko breadcrumbs.

Once coated, place the cheese sticks on a lined baking sheet in a single layer and freeze for at least 45 minutes.

Heat the vegetable oil in a deep pot or fryer to 350°F (175°C) to ensure proper frying.

Carefully add the cheese sticks in batches and fry for about 2 to 3 minutes or until golden brown.

Transfer the fried mozzarella sticks to a wire rack to cool for a few minutes before serving.

Serve immediately with warm marinara sauce for dipping.
