Tips
Pat fries completely dry after draining to maximize crispness during baking; moisture prevents browning.
Spread fries in single layer without overlapping for even cooking and uniform golden color.
Use a spray bottle for consistent olive oil distribution; aerosol spray may deposit unevenly.
Good to Know
Keep in airtight container at room temperature for up to 2 days. Reheat on baking sheet at 375 degrees F for 5-10 minutes to restore crispness.
Marinate potatoes in refrigerator up to 4 hours before drying and baking. Do not bake ahead; best served immediately after cooking.
Serve hot as side dish with burgers, sandwiches, or grilled proteins. Pair with ketchup, vinegar, or aioli.
Common Mistakes
Overcrowd the baking sheet to avoid steaming instead of baking; use two sheets if needed.
Skip the drying step to prevent soggy fries; paper towels are essential.
Avoid opening oven door mid-bake to maintain consistent temperature for even cooking.
