Preheat oven to 425 degrees. Gather your ingredients so that you have everything close at hand. Prepare your potatoes. Peel and cut into thin strips using a French Fry cutter or a sharp knife. Mince the garlic.
Place the fries into a large mixing bowl and drizzle with the olive oil. Add minced garlic, thyme, seasoned salt, and freshly ground black pepper. Toss until evenly coated.
Line a baking sheet with foil (shiny side up), and then spray the foil with baking spray. Spread the fries onto the foil-lined baking sheet. Bake for 30 minutes, turning fries halfway through the baking process.
Return the fries to the bowl and sprinkle with 1/2 cup freshly grated Parmesan and dried parsley. If desired, add 1-2 more tablespoons of olive oil. Carefully stir to coat and spread once again on the foiled-lined baking sheet. Bake for another 10 minutes.
To serve, sprinkle the fries with the remaining Parmesan cheese and sea salt. Serve hot. Serves 4.
