Cut the mozzarella cheese sticks into even-sized pieces.
In a shallow bowl, beat the eggs and season with salt and pepper.
Place the flour and breadcrumbs in separate bowls.
Dredge each cheese stick in the flour, then dip into the beaten eggs, and finally coat with breadcrumbs.
Repeat the process for a thicker coating, if desired.
Heat oil in a frying pan over medium heat.
Carefully place the coated cheese sticks into the hot oil and fry until golden brown and crispy, about 1-2 minutes per side.
Remove from the oil and drain on paper towels.
Serve hot with marinara sauce or your favorite dipping sauce.
Enjoy your homemade mozzarella sticks!
