In three separate shallow bowls, place the flour in one, beaten eggs in another, and combine breadcrumbs, grated Parmesan cheese, dried oregano, dried basil, garlic powder, onion powder, paprika, salt, and pepper in the third bowl. Mix the breadcrumb mixture well to combine all the seasonings evenly.

Remove the mozzarella string cheese sticks from their packaging and cut them in half to make 24 shorter sticks. This step is optional, but it can make handling and frying easier.

Dredge each mozzarella stick in the flour, shaking off any excess.

Dip the floured stick into the beaten eggs, ensuring it's evenly coated.

Roll the egg-coated stick in the seasoned breadcrumb mixture, pressing gently to adhere the breadcrumbs.

If you prefer an extra crispy coating, you can repeat the egg and breadcrumb coating process once more after the first coating has dried.

Place the coated mozzarella sticks on a baking sheet lined with parchment paper and freeze them for at least 30 minutes. This step helps the coating adhere better during frying.

In a deep fryer or heavy-bottomed pot, heat vegetable oil to 350°F (175°C).

Carefully lower a few frozen mozzarella sticks into the hot oil, being cautious not to overcrowd the pot. Fry them for about 2-3 minutes until they are golden brown and crispy.

Remove the fried mozzarella sticks from the oil using a slotted spoon and transfer them to a plate lined with paper towels to drain excess oil. Repeat the frying process with the remaining mozzarella sticks.

Serve the crispy mozzarella sticks hot with marinara sauce for dipping.
