Peel and cut the potatoes into thin sticks.
Place the potatoes in a deep bowl, cover with water, add salt and mix. The salt will draw out excess moisture from the potatoes. Soak for 2 hours. This step can be skipped if you need the fries asap.
Drain the potatoes and dry thoroughly them using paper towels.
Preheat the oil over low-medium heat or at 130℃/270℉ if using a food thermometer.
Add about ⅓ of the potatoes to avoid overcrowding the saucepan and let them cook until they're soft and you can easily go through them using a knife, about 5-7 minutes.
Remove them from the oil and place them on a tray lined with paper towels to absorb the excess fat. Let them cool down completely.
Preheat the oil to medium-high heat or 180℃/350℉ if using a food thermometer.
Add ⅓ of the potatoes again and this time remove them when they're very golden. Place them on a baking tray with a cooling rack on top. You can keep them hot in the oven at 150℃/300℉ as you fry more.
Mix the salt and spices in a small bowl and sprinkle the mix over the potatoes, mixing in between. Repeat with the parmesan cheese and fresh parsley.
Serve immediately.
