Place the mozzarella sticks in the freezer for at least 1 hour to prevent the cheese from melting too quickly during frying.
In a shallow bowl, combine the flour, cayenne pepper, paprika, and garlic powder.
Beat the eggs in a separate bowl.
Place the breadcrumbs into a third shallow bowl.
Dip each mozzarella stick into the seasoned flour mixture.
Coat the stick in the beaten eggs.
Roll it thoroughly in breadcrumbs.
For extra crispiness, repeat the egg and breadcrumb coating one more time.
Heat oil in a deep skillet or fryer to 350°F (175°C).
Fry the Spicy Nashville-Style Mozzarella Sticks in batches for 1–2 minutes or until golden brown and crispy.
Remove and place on paper towels to drain excess oil.
Serve immediately with ranch dressing, marinara sauce, or spicy dipping sauce.
