2. Slice the Potatoes
Cut the peeled potatoes into thin strips, about 1 cm (0.4 inch) thick. Keeping the slices uniform ensures even cooking.
3. Season the Fries
In a large bowl, toss the potato slices with mayonnaise. This helps the Parmesan stick and adds flavor without excess oil. Sprinkle with salt and black pepper to taste.
4. Add Parmesan
Sprinkle the grated Parmesan over the seasoned potatoes. Toss until each fry is coated evenly with cheese.
5. Arrange on Baking Sheet
Line a baking sheet with parchment paper or lightly grease it. Spread the fries in a single layer, leaving space between each one for even crisping.
6. Bake Until Golden
Place the tray in the oven and bake for about 25–30 minutes, flipping once halfway through. Remove when the fries are golden brown and crispy.
Serving Suggestion
Serve your Baked Parmesan Potato Fries hot, paired with your favorite dipping sauce such as marinara, garlic aioli, or classic ketchup. They make a fantastic side dish or a satisfying snack on their own.
