Preparation:

1. Begin by thoroughly washing and scrubbing the potatoes. Peeling is optional; leaving the skin on adds texture and flavor.
2. Cut the potatoes into sticks approximately 1/4 inch wide and 3-4 inches long, aiming for uniform cuts for even frying.

Soaking and Drying:

1. Soak the potato sticks in cold water for 15-30 minutes to remove excess starch, contributing to a crispier fry.
2. After soaking, thoroughly pat the potatoes dry with paper towels to remove as much moisture as possible.

Garlic Infused Oil:

1. In a small saucepan, heat the olive oil over low heat. Add the minced garlic and gently cook for 2-3 minutes, ensuring the garlic does not brown. This process will infuse the oil with garlic flavor. Set aside.

Double Frying:

1. Fill a deep, heavy-bottomed pot with vegetable oil to a depth of 3 inches and heat to 325°F (160°C) for the first fry.
2. Carefully fry the dried potato sticks in batches to avoid overcrowding, for about 3-4 minutes per batch, until they are just pale and slightly golden. Remove and let them drain on a paper towel-lined plate.
3. Increase the oil temperature to 375°F (190°C) for the second fry. Return the fries to the hot oil and fry until golden brown and crispy, approximately 1-2 minutes.
4. Again, remove the fries and drain on clean paper towels.

Tossing and Seasoning:

1. Place the double-fried potatoes in a large bowl. Drizzle with the garlic-infused olive oil, ensuring the fries are evenly coated. Season with salt and black pepper and toss again.

Finishing Touches:

1. Sprinkle the fries with the freshly chopped parsley. If using, add grated Parmesan cheese and toss to ensure the fries are evenly coated with the seasoning and cheese.

Serve and Enjoy:

1. Serve the crispy garlic French fries immediately, enjoying the enhanced aroma and flavor.
2. These garlic French fries, with their crispy exterior and fluffy interior, highlighted by a rich garlic, and parmesan flavor, make a perfect side dish or indulgent snack.
