Instructions
 

  • Wash, peel, and cut potatoes into ½-inch thick fries. Then, if using the oven method, add your baking sheet to the oven and preheat it to 390ºF (200ºC).
  • This is optional, but it helps to get rid of some of the starch, which results in crispier fries. Fill a large bowl with water and add ice and add the potatoes. Soak for at least 30 minutes, then drain and rinse.
  • Lay them on a few layers of paper towels and dry well. This is important to make sure that the seasoning will stick properly.
  • Add the potatoes to a bowl and coat with 1 tablespoon of oil. Then, add the spice mix and stir until every last piece is well-coated.
  • Take the hot baking sheets out of the oven and spray them with cooking spray. Add the fries in a single layer, giving them enough space in between. Bake for 35-40 minutes, flipping halfway through, until golden brown.
  • If using an air fryer, preheat it to 390ºF (200ºC). Spray the air fryer basket with cooking spray, then add the fries in a single layer. Cook for 20-25 minutes, or until golden brown.
  • Finish by sprinkling a little bit of sea salt before serving.

Notes

  • Cut the fries into similar sizes. This ensures that they will cook evenly and at about the same rate.
  • Soak the potatoes in ice-cold water. If you have the time, I recommend soaking the fries anywhere from 30 minutes to 2 hours to get rid of the starch. This is my best trick for making crispy baked potatoes.
  • Dry them very well before seasoning. After soaking, make sure to completely dry the potatoes. This will help the seasoning stick better and will prevent the potatoes from getting soggy.
  • Preheat your baking sheets. Instead of using parchment paper, preheat your baking sheets and spray them with cooking spray. This creates a non-stick layer, and since you're not using parchment paper, the potatoes can have direct contact with the surface and get super crispy.
  • Work in batches if needed. It's essential to not overcrowd the air fryer basket or the baking sheets. If you don't give the potatoes enough space, they'll steam instead of crisp up, and will end up being soggy.
 
Storage
This recipe is best served when fresh, as the fries get soft when they cool down. However, if you have any leftovers, store them in an airtight container in the fridge for 3-4 days.
