Boil the potatoes: Peel the potatoes and cut them into even-sized sticks. Fill a large pot with salted water and bring it to a boil. Add the potato sticks and cook for 8-10 minutes, or until tender. Drain the potatoes and set them aside to cool slightly.

Mash the potatoes: While the potatoes cool, finely chop the parsley. In a large bowl, mash the cooked potatoes until smooth.

Season and combine: Add the chopped parsley, cornstarch, grated cheese, salt, pepper, and paprika to the mashed potatoes. Mix everything well until evenly combined.

Shape the potato sticks: With slightly damp hands, shape the potato mixture into sticks or desired shapes (think thick french fries).

Set up the breading station: Prepare three separate bowls for breading. In the first bowl, place the flour. In the second bowl, whisk the eggs until well beaten. In the third bowl, add the breadcrumbs.

Breading the potato sticks: Working in batches, coat each potato stick in flour, then dip it into the beaten eggs, and finally, coat it evenly with breadcrumbs.

Heat the oil: Heat enough vegetable oil in a large frying pan or deep fryer over medium-high heat (around 350°F/175°C).

Fry the potato sticks: Carefully add the breaded potato sticks to the hot oil and fry for 3-4 minutes per batch, or until golden brown and crispy on all sides. Don't overcrowd the pan, so the potato sticks have space to cook evenly.

Drain and serve: Using a slotted spoon, transfer the fried potato sticks to a paper towel-lined plate to drain excess oil. Serve hot, garnished with additional chopped parsley (optional).
